We're going to talk a little about 47 00:02:20,319 --> 00:02:22,639 mc cable and ac cable and we're going to be 48 00:02:22,759 --> 00:02:27,400 relating to an article that I wrote on the subject 49 00:02:28,360 --> 00:02:32,599 over on our website, fasttracksystem dot com. Over on the blog, 50 00:02:33,039 --> 00:02:35,560 so if you check it out, you will see it 51 00:02:35,599 --> 00:02:38,560 over in the blogs. And it's the actually it's the 52 00:02:38,599 --> 00:02:42,840 first blog of twenty twenty five. Very first one came 53 00:02:42,879 --> 00:02:46,759 out on January third, and we're talking about bundling of 54 00:02:47,680 --> 00:02:50,599 multiiconductor cable assemblies and more specifically, we're going to be 55 00:02:50,599 --> 00:02:53,879 talking about MC and AC cable today, but we'll just 56 00:02:53,960 --> 00:02:57,879 give you some general information about bundling. What bundling is, 57 00:02:58,080 --> 00:03:01,840 what is considered bundling a term that is not defined 58 00:03:01,879 --> 00:03:04,520 in the NEEC, but again you can kind of get 59 00:03:04,560 --> 00:03:08,719 there if you will, by just the language that's in 60 00:03:08,759 --> 00:03:11,039 the code itself. So we're going to be talking about 61 00:03:11,039 --> 00:03:13,680 all of that today on this episode. But again it 62 00:03:13,840 --> 00:03:16,879 remind you, folks, if you really want to get into 63 00:03:16,919 --> 00:03:19,360 a good course about learning the National Electrical Code, get 64 00:03:19,439 --> 00:03:21,080 rid of all the fluff. You just want it to 65 00:03:21,120 --> 00:03:25,919 be not full of Paul's opinions. And we've purposely constructed 66 00:03:25,919 --> 00:03:28,800 a program that does that gets rid of my opinions 67 00:03:28,840 --> 00:03:32,759 in there, and basically, you read it, you have chevrons 68 00:03:32,800 --> 00:03:35,360 you go to your codebook, you read what the code says, 69 00:03:35,400 --> 00:03:37,719 and you come back and you see how we paraphrased it, 70 00:03:38,159 --> 00:03:42,080 and that together helps you learn the National Electrical Code. 71 00:03:42,120 --> 00:03:45,680 And that's what makes our programs so popular. And if 72 00:03:45,719 --> 00:03:48,240 you still want a little bit of that video flavored, 73 00:03:48,280 --> 00:03:51,039 then obviously you can subscribe to the fast Tracks Tube, 74 00:03:51,439 --> 00:03:54,919 which is our video delivery platform, which is exclusive to us, 75 00:03:55,879 --> 00:03:57,840 and that's where we have the majority of our videos. 76 00:03:57,840 --> 00:04:01,240 For example, we did a two hour webinar just yesterday 77 00:04:01,759 --> 00:04:04,360 and that is available over on FasTracks Tube. 78 00:04:04,039 --> 00:04:06,240 Speaker 2: And it's not free. It's only two subscribers. 79 00:04:07,240 --> 00:04:08,919 Speaker 3: And in the future you're going to see less and 80 00:04:09,000 --> 00:04:12,319 less on our social media platforms and more of our 81 00:04:12,400 --> 00:04:16,279 content over on our own proprietary platform. Why because we're 82 00:04:16,279 --> 00:04:19,480 in business number two. We have made it so affordable 83 00:04:19,480 --> 00:04:22,199 that why wouldn't you do it?

Okay, 127 00:06:40,920 --> 00:06:42,800 so today we're going to be talking a little bit 128 00:06:42,839 --> 00:06:47,040 about the aspects of bundling and what is bundling, and 129 00:06:47,120 --> 00:06:50,319 we're going to show you talk about the provision of 130 00:06:50,439 --> 00:06:55,360 where if you have MC or ac cable that if 131 00:06:55,399 --> 00:07:00,439 you have you meet certain conditions then you may be bundling. 132 00:07:00,959 --> 00:07:02,319 Speaker 2: Okay, and we'll talk about that. 133 00:07:02,399 --> 00:07:04,480 Speaker 3: But you may be bundling your MC cable, which is 134 00:07:04,480 --> 00:07:07,480 a multiiconductor cable. You may be bundling it for more 135 00:07:07,519 --> 00:07:10,199 than twenty four inches without maintaining any spacing, means they're 136 00:07:10,279 --> 00:07:12,480 touching continuously for twenty four inch. 137 00:07:12,560 --> 00:07:13,360 Speaker 2: Over twenty four. 138 00:07:13,240 --> 00:07:18,839 Speaker 3: Inches, then that is basically bundling. And when you do that, 139 00:07:18,920 --> 00:07:21,480 you're going to have to do some type of adjustment. 140 00:07:22,000 --> 00:07:24,199 An adjustment just means that you're going to take whatever 141 00:07:24,199 --> 00:07:27,120 the capacity is you thought the conductor had and you're 142 00:07:27,160 --> 00:07:29,680 going to reduce it to what it actually can carry 143 00:07:30,160 --> 00:07:31,519 due to the condition of use. 144 00:07:31,759 --> 00:07:32,920 Speaker 2: And that's called adjustments. 145 00:07:33,680 --> 00:07:36,040 Speaker 3: We also have what's called corrections, which have to do 146 00:07:36,120 --> 00:07:40,360 with ambient temperatures, but that's for a totally different episode. 147 00:07:40,639 --> 00:07:42,560 And if you really want to get a good deep 148 00:07:42,639 --> 00:07:45,160 dive into adjustment and corrections, and I encourage you to 149 00:07:45,240 --> 00:07:49,040 go over to fast tracks Tube, that is fast tracks 150 00:07:49,120 --> 00:07:53,759 Tube fas t t r X tube dot com and 151 00:07:54,160 --> 00:07:57,639 watch the d rating demystified video that we did that 152 00:07:57,839 --> 00:08:02,319 really deep dives into continuous slowdes non continuous loads, conditions 153 00:08:02,319 --> 00:08:05,319 of use, the eighty three percent rule when it comes 154 00:08:05,360 --> 00:08:06,600 to three, ten dot twelve. 155 00:08:07,040 --> 00:08:09,600 Speaker 2: We cover all of that, and that is available over 156 00:08:09,639 --> 00:08:11,480 on fast Tracks Tube. 157 00:08:11,920 --> 00:08:14,480 Speaker 3: A lot of good content over there, and tons of 158 00:08:14,519 --> 00:08:17,360 new stuff's coming.

Okay, 172 00:08:56,200 --> 00:08:58,200 So this is kind of a new thing for us, 173 00:08:58,279 --> 00:09:01,200 and we're excited about it because it's going to engagement 174 00:09:01,720 --> 00:09:02,600 into the videos. 175 00:09:03,720 --> 00:09:05,360 Speaker 2: All right, So let's talk. 176 00:09:05,240 --> 00:09:08,919 Speaker 3: About this thing three ten, fifteen C one when we 177 00:09:09,000 --> 00:09:12,519 have more than three current carrying conductors, So if I 178 00:09:12,519 --> 00:09:15,200 have a twelve two, now i've got typically i'm gonna 179 00:09:15,200 --> 00:09:16,639 have two current caring conductors. 180 00:09:16,919 --> 00:09:21,000 Speaker 2: If I have a twelve three, I might have three 181 00:09:21,039 --> 00:09:22,279 current current conductors. 182 00:09:22,399 --> 00:09:24,960 Speaker 3: Okay, depending on whether the neutral, whether or not you're 183 00:09:25,000 --> 00:09:27,799 dealing with a system that that brand circuit is supplying 184 00:09:27,840 --> 00:09:31,320 non linear loads like fluorescent lighting, then of course that 185 00:09:31,360 --> 00:09:32,720 neutral is going to carry current. 186 00:09:32,759 --> 00:09:34,399 Speaker 2: It's going to be a non linear load. 187 00:09:35,559 --> 00:09:39,960 Speaker 3: We can also find out what neutrals are when they 188 00:09:40,080 --> 00:09:43,840 are considered current carrying by just going to three ten 189 00:09:43,960 --> 00:09:48,600 fifteen E and E is titled neutral conductor, and you 190 00:09:48,720 --> 00:09:51,159 go through there and you can see that, for example, 191 00:09:51,240 --> 00:09:54,159 three wires, two hots and a neutral in a four 192 00:09:54,200 --> 00:09:57,120 wire three phase y system, then that neutral is going 193 00:09:57,159 --> 00:09:59,559 to carry about the same current as any of the 194 00:09:59,639 --> 00:10:02,960 unground the conductors or the hots, so you definitely will 195 00:10:03,399 --> 00:10:05,519 count it as a current current. But the one that 196 00:10:05,559 --> 00:10:08,519 I just said fluorescence, for example, you could have a 197 00:10:08,559 --> 00:10:11,559 situation where it's a four wire three phase y circuit 198 00:10:12,039 --> 00:10:15,559 where the major portion of the load consists of non 199 00:10:15,600 --> 00:10:18,960 linear loads. Well, if it's a brand circuit for fluorescent lighting, 200 00:10:19,039 --> 00:10:22,799 then I can promise you that a major portion of 201 00:10:22,919 --> 00:10:25,720 that load on that brand circuit will be. 202 00:10:27,200 --> 00:10:28,360 Speaker 2: Non linear loads. 203 00:10:28,639 --> 00:10:32,200 Speaker 3: Okay, So if that's the case, then you're going to 204 00:10:32,279 --> 00:10:34,039 have a lot of harmonic currents in there, and that 205 00:10:34,080 --> 00:10:35,720 neutral is going to carry current and you're going to 206 00:10:35,759 --> 00:10:37,240 treat it as a current care and conductor. 207 00:10:37,320 --> 00:10:39,399 Speaker 2: So that's important for us to. 208 00:10:39,399 --> 00:10:42,399 Speaker 3: Understand because when we start to see these allowances in 209 00:10:42,440 --> 00:10:44,840 a second, when we get there at three ten fifteen 210 00:10:45,360 --> 00:10:48,919 C one D for MC and AC cable, when it 211 00:10:48,919 --> 00:10:52,480 comes to bundling, you're going to see that it can 212 00:10:52,519 --> 00:10:55,080 play a dramatic role on whether or not you get 213 00:10:55,120 --> 00:10:58,200 to use the you know, get to ignore adjustment factors 214 00:10:58,399 --> 00:11:01,399 or you have to say, crap, I have now got 215 00:11:01,399 --> 00:11:03,440 a situation where I have more than three current current 216 00:11:03,480 --> 00:11:06,240 conductors in this cable, and so now I'm going to 217 00:11:06,279 --> 00:11:08,639 have to adjust the opacity and that can make or 218 00:11:08,679 --> 00:11:11,080 break your day, depending on if you had a load 219 00:11:11,120 --> 00:11:13,919 that you needed a certain conductor for a certain amount 220 00:11:13,960 --> 00:11:16,600 of amps, and now you do some kind of adjustment, 221 00:11:17,159 --> 00:11:19,519 and now you got a conductor that doesn't have enough 222 00:11:19,759 --> 00:11:23,320 capability to handle the load because it is adjusted the 223 00:11:23,360 --> 00:11:26,600 opacity down below what you need. And now you got 224 00:11:26,600 --> 00:11:30,279 a problem. Okay, and then you're like, what do I do? Well, shit, 225 00:11:30,440 --> 00:11:33,440 if you don't detect it after it's already done and 226 00:11:33,480 --> 00:11:35,840 inspector finds out or somebody looks at it, then you're 227 00:11:35,879 --> 00:11:39,399 like Jesus, who do I backcharge for that? Nobody? Because 228 00:11:39,440 --> 00:11:42,000 you did it, you got to eat it. That's why 229 00:11:42,039 --> 00:11:44,519 it's so important to understand the National Legical Code. Now, 230 00:11:44,519 --> 00:11:46,720 there are some key principles that we'll talk about, like, 231 00:11:46,759 --> 00:11:50,240 for example, when you're stacking or bundling your EMCs and 232 00:11:50,320 --> 00:11:53,279 bridal rings whatever, then you know just to you know, 233 00:11:53,600 --> 00:11:58,200 not to put more than ten twelve two's for example, 234 00:11:58,679 --> 00:12:00,360 and you don't intermix. 235 00:11:59,919 --> 00:12:02,799 Speaker 2: It with ten gauge EMC's or anything like that, And 236 00:12:02,840 --> 00:12:03,639 we'll talk about that. 237 00:12:04,440 --> 00:12:06,559 Speaker 3: But there's just certain things that you learn in the 238 00:12:06,600 --> 00:12:09,480 trade and you have to be aware of that. An 239 00:12:09,480 --> 00:12:12,799 apprentice or somebody learning early on might not when you 240 00:12:12,840 --> 00:12:14,600 go tell them to run a bunch of mc cable, 241 00:12:14,639 --> 00:12:18,279 for example, they might not think about these code rules. 242 00:12:18,440 --> 00:12:21,919 And you can't blame anybody but yourself. If you're the 243 00:12:21,960 --> 00:12:25,519 master and your apprentice does this, they're under your watch, 244 00:12:25,639 --> 00:12:28,480 so we can't kick that bucket to somebody else, right, 245 00:12:29,039 --> 00:12:32,399 you're responsible for them. So that's the stuff we're going 246 00:12:32,440 --> 00:12:33,960 to talk about in today's episode. 247 00:12:33,960 --> 00:12:36,679 Speaker 2: Okay, now, before I get too deep into this. 248 00:12:36,759 --> 00:12:39,200 Speaker 3: I also want to tell you that I have a 249 00:12:39,200 --> 00:12:43,240 great blog on this subject and it's a living document 250 00:12:43,799 --> 00:12:45,480 and so if I feel like I want to add 251 00:12:45,519 --> 00:12:47,279 something else to it, we add more to it. 252 00:12:47,440 --> 00:12:47,679 Speaker 2: Again. 253 00:12:47,759 --> 00:12:49,639 Speaker 3: We don't want and done these things. That's why it's 254 00:12:49,639 --> 00:12:53,080 so important for you to follow our blogs. And we 255 00:12:53,120 --> 00:12:56,759 have dozens of blogs that you read them. And I'm 256 00:12:56,759 --> 00:12:59,120 a big believer in reading stuff. You know, we do 257 00:12:59,200 --> 00:13:02,679 have the video platfor videos a good supplemental I get it, 258 00:13:03,080 --> 00:13:06,840 but we have so bad attention spans today that how 259 00:13:06,840 --> 00:13:09,440 many times have you watched a video and you've watched 260 00:13:09,480 --> 00:13:11,200 it and you kind of forgot what the hell was 261 00:13:11,240 --> 00:13:13,279 in it, and you're like, shit, I gotta go back 262 00:13:13,320 --> 00:13:15,840 and watch it again. That's when people always say, hey, Paul, 263 00:13:15,879 --> 00:13:17,600 I want to rewind feature so I can go back 264 00:13:17,639 --> 00:13:21,879 and forth on a video. It's because videos are great 265 00:13:21,919 --> 00:13:25,799 as supplemental, but I never will buy into the fact 266 00:13:25,799 --> 00:13:29,039 that they are one hundred percent the best way to 267 00:13:29,240 --> 00:13:31,000 learn something technical. 268 00:13:30,639 --> 00:13:31,399 Speaker 2: Like the code. 269 00:13:31,519 --> 00:13:33,799 Speaker 3: I think you have to read it, and I think 270 00:13:33,840 --> 00:13:36,480 you read it, and the number one thing that people 271 00:13:36,519 --> 00:13:40,200 struggle with is comprehension. You read it and you don't 272 00:13:40,279 --> 00:13:43,639 know what you just read and that's a problem, and 273 00:13:43,720 --> 00:13:45,720 so we have to work on that. And that's why 274 00:13:45,759 --> 00:13:48,559 what we do in our program is give you the code, 275 00:13:49,080 --> 00:13:51,440 then we give you a chevron to the code section. 276 00:13:52,159 --> 00:13:56,360 Speaker 2: You go, you stop, you go to the codebook, you read. 277 00:13:56,120 --> 00:14:00,360 Speaker 3: The section, then you come back to the course material 278 00:14:00,960 --> 00:14:05,039 and it just makes better sense. And that's a scenario 279 00:14:05,080 --> 00:14:09,039 that we started years ago, and other people slowly copy 280 00:14:09,120 --> 00:14:12,759 the concept, but that is what we started when we 281 00:14:12,840 --> 00:14:16,120 created the fast Tracks system. It's not about the code. 282 00:14:16,960 --> 00:14:19,240 It's not about delivery the code. It's not about the 283 00:14:19,279 --> 00:14:24,320 code content. It's about the system and how we created 284 00:14:24,360 --> 00:14:27,519 the system, moving in and out of the codebook, illustrations, 285 00:14:27,960 --> 00:14:31,720 putting everything together. That's what we have the trademarks on okay. 286 00:14:32,200 --> 00:14:36,120 It is not one of those things that are code 287 00:14:36,200 --> 00:14:40,399 is code okay. And obviously we paraphrase the code where 288 00:14:40,399 --> 00:14:42,240 we need to, because again we don't want to copy 289 00:14:42,279 --> 00:14:45,159 it verbatim. We like to paraphrase it because it kind 290 00:14:45,159 --> 00:14:46,879 of gives it a little bit of flavor rather than 291 00:14:46,960 --> 00:14:50,120 just boring content that type of thing. But it all 292 00:14:50,200 --> 00:14:52,799 comes together at the end. So I encourage you to 293 00:14:52,879 --> 00:14:54,960 go check out the blog. It's over. You can't miss it. 294 00:14:55,000 --> 00:14:57,159 You go to our website, you click blog and it'll 295 00:14:57,159 --> 00:14:59,720 take you right to the blogs. Now this is January 296 00:14:59,759 --> 00:15:02,000 three blog, by the way, so it is again the 297 00:15:02,000 --> 00:15:04,879 first blog of twenty twenty five. So it's kind of 298 00:15:04,919 --> 00:15:07,879 special because we took the time to break it out. 299 00:15:08,320 --> 00:15:09,360 Speaker 2: And again mc. 300 00:15:09,639 --> 00:15:15,519 Speaker 3: AC cable, but let's talk multiiconductor cables assemblies in general. Okay, 301 00:15:16,120 --> 00:15:18,679 we're just sitting here, we have our coffee, we're chatting 302 00:15:18,679 --> 00:15:22,080 it out. So non metallic she's cable in m Okay, 303 00:15:22,120 --> 00:15:24,559 many people call it romex, which is a brand name 304 00:15:24,639 --> 00:15:27,360 for a product from South Wire, but it's basically just 305 00:15:27,399 --> 00:15:30,120 non metallic she's cable that can be bundled. We have 306 00:15:30,200 --> 00:15:33,240 rules in three thirty four dot eighty and again you 307 00:15:33,240 --> 00:15:35,759 hear me throw out these code references. You can always 308 00:15:35,799 --> 00:15:38,519 pause this podcast and go read it. I encourage you 309 00:15:38,559 --> 00:15:41,480 to be that engaged. Of course, if you're out on 310 00:15:41,519 --> 00:15:44,000 the job site and you're listening while you're working, get 311 00:15:44,000 --> 00:15:44,519 your work done. 312 00:15:44,639 --> 00:15:45,320 Speaker 2: Make that money. 313 00:15:46,039 --> 00:15:48,960 Speaker 3: That's that's how the world goes around. Make that money. 314 00:15:49,279 --> 00:15:52,039 But when you get your downtime, go to the codel 315 00:15:52,080 --> 00:15:54,840 can read it, go back and forth. Really get engaged 316 00:15:54,840 --> 00:15:56,879 in it because it's going to help solidify it and 317 00:15:56,960 --> 00:15:58,879 you learn it. I as a funny. I hear a 318 00:15:58,919 --> 00:16:01,240 guy all the time. He's he's so cool. He's over 319 00:16:01,279 --> 00:16:04,320 in TikTok. He's a cool guy. His name he goes 320 00:16:04,320 --> 00:16:07,600 by Philly Kso he's cool dude. And he'll tell you 321 00:16:07,720 --> 00:16:09,279 right up front. He says he's a dude. He says, 322 00:16:09,279 --> 00:16:12,120 I'm a duel man. He does it, okay, you know 323 00:16:12,200 --> 00:16:15,000 a kid. He does the work, but he doesn't know 324 00:16:15,120 --> 00:16:18,679 all of the code and he doesn't have to because 325 00:16:18,720 --> 00:16:21,039 he knows to stop and go read the code when 326 00:16:21,039 --> 00:16:23,480 he needs it. Other than that, he's just a product 327 00:16:23,519 --> 00:16:26,200 of doing it. He's got his hands dirty. He's got 328 00:16:26,200 --> 00:16:28,960 the cuts on his hands to prove it. So when 329 00:16:29,000 --> 00:16:32,159 we do things in the code now, what we do things, 330 00:16:32,159 --> 00:16:35,720 we're doing it per code. We probably have looked before 331 00:16:36,200 --> 00:16:39,200 and we're just doing it because we've done repetition over 332 00:16:39,240 --> 00:16:41,519 and over and over again. But he's pretty cool because 333 00:16:41,519 --> 00:16:44,120 when he doesn't know something about code, he's very honest 334 00:16:44,120 --> 00:16:47,039 about it, and he says, I don't know what the 335 00:16:47,080 --> 00:16:49,879 code says on this, he'll go read it and interpret it. 336 00:16:49,919 --> 00:16:51,799 But he doesn't carry the code book in his pocket 337 00:16:52,200 --> 00:16:54,159 and he doesn't have to, and you don't have to either, 338 00:16:54,759 --> 00:16:58,399 but it's healthy for you to understand the code because 339 00:16:58,399 --> 00:17:01,080 I think in a recent episode he was doing something 340 00:17:01,120 --> 00:17:03,679 and he thought that for example, I think it was 341 00:17:03,720 --> 00:17:07,319 the afcis when you're moving a panel and if you move, 342 00:17:07,400 --> 00:17:10,119 if you move it not more than six feet, then 343 00:17:10,160 --> 00:17:12,279 you don't have to even on a service change, you 344 00:17:12,359 --> 00:17:15,400 don't have to change and put afcies in. Now we 345 00:17:15,400 --> 00:17:17,400 can get into the semantics of whether or not you 346 00:17:17,519 --> 00:17:20,160 do an upgrade. And if you did an upgrade, then 347 00:17:20,200 --> 00:17:25,240 the jurisdiction could consider that new then they may invoke something. 348 00:17:25,279 --> 00:17:27,640 But if it's a like for like, for example, just 349 00:17:27,720 --> 00:17:29,720 taking one hundred damn fuse and turning into a hundred 350 00:17:29,759 --> 00:17:33,000 damn circuit breaker, then if you're you know, we can 351 00:17:33,039 --> 00:17:36,079 get into the semantics. But the point was he thought 352 00:17:36,119 --> 00:17:39,200 the six foot measurement was from lug to lug, and 353 00:17:39,240 --> 00:17:39,880 it's really not. 354 00:17:40,000 --> 00:17:41,680 Speaker 2: It's from enclosure to enclosure. 355 00:17:41,920 --> 00:17:45,039 Speaker 3: Okay, so it's the it's the wire between or the 356 00:17:45,079 --> 00:17:48,440 cable between the two enclosures. It doesn't include the portion 357 00:17:48,519 --> 00:17:51,440 that goes in into the lugs. And uh, it can 358 00:17:51,519 --> 00:17:54,759 make a huge difference, right, It makes a difference because 359 00:17:55,119 --> 00:17:58,400 it means that you can only go probably physically three 360 00:17:58,480 --> 00:18:00,920 feet because you're going to have at least a foot 361 00:18:00,920 --> 00:18:03,720 and a half in each one of the enclosures to determinate. 362 00:18:04,119 --> 00:18:07,119 And so that's why it's so important to read the code. 363 00:18:07,480 --> 00:18:09,359 And that's when he realized he did read it, and 364 00:18:09,400 --> 00:18:11,519 he says, oh wow, I was wrong. It's it's six 365 00:18:11,599 --> 00:18:15,160 feet from enclosure to enclosure, and so yeah, that's a 366 00:18:15,200 --> 00:18:18,000 significant difference. And that's because he stopped and went and 367 00:18:18,039 --> 00:18:20,720 read the code. Okay, that's the importance of it. And 368 00:18:20,720 --> 00:18:22,480 that's what you got to do as a trade person. 369 00:18:22,920 --> 00:18:24,680 You have to be engaged in the code. Whether you 370 00:18:24,720 --> 00:18:27,400 want to be hate the code, it doesn't matter. What 371 00:18:27,440 --> 00:18:31,119 you do is all founded in code anyway. Okay, all right, 372 00:18:31,359 --> 00:18:32,200 So anyway. 373 00:18:32,200 --> 00:18:35,680 Speaker 2: We're going to talk today about bundling. 374 00:18:35,400 --> 00:18:37,400 Speaker 3: And we're going to be looking at three ten fifteen 375 00:18:37,640 --> 00:18:40,279 C one, but we're going to be keing the focus 376 00:18:40,319 --> 00:18:42,240 in on the mc cable as it relates to the 377 00:18:42,359 --> 00:18:47,599 article that we that we wrote on our website. Okay, now, bundling, 378 00:18:48,480 --> 00:18:50,480 if you go to the NEC and you look at 379 00:18:50,519 --> 00:18:54,119 three ten fifteen C one and you look at it 380 00:18:54,240 --> 00:18:57,200 and it says more than three current current conductors. Now, 381 00:18:57,240 --> 00:18:59,400 the first thing that people struggle with this is the 382 00:18:59,400 --> 00:19:03,279 way this is one big run on paragraph, the way 383 00:19:03,319 --> 00:19:07,599 that it runs. Okay, multiple sentences grouped together, and one 384 00:19:07,640 --> 00:19:09,720 of our goals for the code panels was to try 385 00:19:09,720 --> 00:19:12,759 to break things out. But obviously some things get missed, 386 00:19:12,839 --> 00:19:15,200 or maybe they felt that this was pretty self explanatory 387 00:19:15,200 --> 00:19:18,480 they didn't need to break it out again. Code Panel 388 00:19:18,759 --> 00:19:20,599 six is probably the one that was working on this, 389 00:19:20,680 --> 00:19:22,880 and it's not like it's not like they didn't have 390 00:19:22,920 --> 00:19:28,039 their hands full with some other issues going on. And 391 00:19:29,079 --> 00:19:31,039 you might say, what are you talking about, Paul, And 392 00:19:31,079 --> 00:19:33,799 I'll just say, if you know, you know, if you 393 00:19:33,839 --> 00:19:36,160 don't know, it's best you don't get involved in it 394 00:19:36,200 --> 00:19:38,279 because it could end you. You could end up being 395 00:19:38,359 --> 00:19:40,680 deposed or something, so just. 396 00:19:40,240 --> 00:19:41,039 Speaker 2: Just ignore it. 397 00:19:41,720 --> 00:19:43,400 Speaker 3: But they had a lot of work on their plate, 398 00:19:43,519 --> 00:19:46,240 so they probably didn't look and nobody probably submitted any 399 00:19:46,319 --> 00:19:50,319 public input in order to break this out anyway, So 400 00:19:50,799 --> 00:19:52,519 let's look at it. I'm gonna read it to you 401 00:19:52,799 --> 00:19:54,400 and I'll break it out for you so it's easier 402 00:19:54,440 --> 00:19:57,119 to understand. And then well we'll tie it into our 403 00:19:57,200 --> 00:20:02,440 MCNAC application. So evere ten fifteen C one says more 404 00:20:02,480 --> 00:20:04,799 than three current car and conductors. So when we have 405 00:20:04,920 --> 00:20:08,519 more than three current carrent conductors, we are going to 406 00:20:08,599 --> 00:20:11,240 have to do what's called an adjustment. And all we're 407 00:20:11,279 --> 00:20:16,279 doing is adjusting the opacity of the conductor. Uh, because 408 00:20:16,319 --> 00:20:18,759 when it comes to more than three current carent conductors, 409 00:20:18,799 --> 00:20:21,880 you have what's called mutual heating, and the heating is 410 00:20:21,920 --> 00:20:24,400 going to cause the temperature of that conductor to rise 411 00:20:24,599 --> 00:20:27,799 quicker to the thermal limit of the insulation. 412 00:20:28,240 --> 00:20:29,160 Speaker 2: So what do we do. 413 00:20:29,240 --> 00:20:31,279 Speaker 3: We dropped the amount of current you can put on 414 00:20:31,319 --> 00:20:34,240 a conductor so that it gives a bit more of 415 00:20:34,279 --> 00:20:38,400 a headroom between the temperature that's generated from the conductor 416 00:20:38,480 --> 00:20:41,599 and the ambient temperature before it gets to a value 417 00:20:42,200 --> 00:20:47,359 that can compromise the rating of the conductor's insulation. And 418 00:20:47,440 --> 00:20:51,799 once you compromise the conductor's insulation, now it starts breaking 419 00:20:51,839 --> 00:20:54,960 down and you're going to get bolted, falts, ground faults, 420 00:20:55,359 --> 00:20:58,759 all types of things you do not want. Okay, So 421 00:20:58,799 --> 00:21:00,799 we're trying to preted against that. 422 00:21:01,400 --> 00:21:01,599 Speaker 2: Right. 423 00:21:02,160 --> 00:21:06,759 Speaker 3: So it reads as it says, the apacity of each 424 00:21:06,839 --> 00:21:11,200 conductor shall be reduced. So that's the goal here, that 425 00:21:11,279 --> 00:21:13,559 the concept is if you have more than three current 426 00:21:13,599 --> 00:21:17,680 current conductors, we're gonna have to drop that capacity, as 427 00:21:17,720 --> 00:21:21,519 shown in Table three ten fifteen C one. Okay, so 428 00:21:21,599 --> 00:21:23,799 that's a little table that you'll have, and that's the 429 00:21:23,839 --> 00:21:26,119 one that says, well, if you have four to six 430 00:21:26,759 --> 00:21:29,960 current current conductors, then you're gonna be using it eighty 431 00:21:30,000 --> 00:21:32,880 percent multiplier. If you have seven to nine, you're gonna 432 00:21:32,920 --> 00:21:35,920 be using a seventy percent. If you have ten to twenty, 433 00:21:36,119 --> 00:21:38,319 you're gonna be using a fifty percent. If you have 434 00:21:38,559 --> 00:21:41,759 over twenty one, for example, twenty one to thirty, it's 435 00:21:41,799 --> 00:21:43,640 going to be forty five, and then thirty one to 436 00:21:43,680 --> 00:21:46,519 forty it's forty and then forty ozh above forty one 437 00:21:46,519 --> 00:21:51,160 and above it's thirty five. Virtually, you're creating a conductor 438 00:21:51,480 --> 00:21:55,799 that will have zero current carrying ability eventually, or you're 439 00:21:55,799 --> 00:21:57,799 working your way towards that at least it won't have 440 00:21:57,920 --> 00:22:01,920 enough current carrying ability to handle whatever your intended load is. 441 00:22:01,960 --> 00:22:04,880 That you installed the brand circuit there in the first place, 442 00:22:04,880 --> 00:22:06,039 for that. 443 00:22:05,960 --> 00:22:07,759 Speaker 2: Becomes a problem. 444 00:22:08,079 --> 00:22:12,279 Speaker 3: So let's read it and I'll explain each piece separate 445 00:22:12,559 --> 00:22:15,880 before we jump down to dealing with MCNAC allowances or 446 00:22:15,920 --> 00:22:18,400 provisions that you can use. Okay, So here it is 447 00:22:18,480 --> 00:22:20,720 again it says the opacity of each conductor shall be 448 00:22:20,799 --> 00:22:23,119 reduced as shown in Table three ten fifteen C one, 449 00:22:23,960 --> 00:22:26,920 where the number of current carr and conductors in a 450 00:22:27,039 --> 00:22:31,920 raceway or a cable exceeds three. So that's the first part. 451 00:22:32,119 --> 00:22:34,359 If you were to bullet point those out, that's what 452 00:22:34,440 --> 00:22:37,000 you would do if you're a highlighter of your codebook 453 00:22:37,039 --> 00:22:39,599 and you're not preparing for an exam, even if you 454 00:22:39,640 --> 00:22:42,480 are preparing for exam, if they let you highlight, this 455 00:22:42,519 --> 00:22:45,279 is where it helps to have multiple color highlights. This 456 00:22:45,480 --> 00:22:48,440 first part here you could do in pink or yellow 457 00:22:48,480 --> 00:22:50,680 or whatever you want to use, because that's the first rule. 458 00:22:51,119 --> 00:22:54,920 So that is raceways or cables where I have more 459 00:22:54,960 --> 00:22:57,920 than three current current conductors, then I'm going to reduce 460 00:22:57,960 --> 00:22:58,599 the opacity. 461 00:22:58,960 --> 00:23:02,039 Speaker 2: Okay. Next it says or. 462 00:23:04,599 --> 00:23:09,240 Speaker 3: Where single conductors or and this is where we kick 463 00:23:09,319 --> 00:23:16,359 in multiconductor cables not installed in raceways are installed without 464 00:23:16,480 --> 00:23:23,039 maintaining spacing for a continuous length longer than twenty four inches. 465 00:23:23,400 --> 00:23:24,720 Speaker 2: Okay, so we get into. 466 00:23:24,519 --> 00:23:26,519 Speaker 3: A lot of debates with people say, well, what the 467 00:23:26,519 --> 00:23:30,480 hell does without maintaining spacing mean and it means exactly 468 00:23:30,559 --> 00:23:34,480 what it says. If you're running a bunch of multiconductor cables, 469 00:23:35,200 --> 00:23:37,400 they're not installed in a raceway. Although, by the way, 470 00:23:37,440 --> 00:23:40,559 you can put multiconductor cables in a raceway. 471 00:23:40,640 --> 00:23:43,920 Speaker 2: It's a myth that people say you can't. Obviously you can. 472 00:23:46,559 --> 00:23:50,680 Speaker 3: So if I'm installing them without maintaining spacing, now the 473 00:23:50,759 --> 00:23:55,000 caveat here it says maintaining spacing for a continuous length 474 00:23:55,160 --> 00:23:58,640 longer than twenty four inches, okay, So if it's under 475 00:23:58,640 --> 00:24:01,759 twenty four inches, not so. That's why when you're running 476 00:24:01,920 --> 00:24:04,480 MC cables example, I'm just using MC because that's the 477 00:24:04,519 --> 00:24:07,640 topic of the day. If you're running them through board holes, 478 00:24:07,640 --> 00:24:10,720 for example, and they're close, they're all touching as they 479 00:24:10,720 --> 00:24:14,799 go through the borehole, that's fine. That's obviously not continuous 480 00:24:14,839 --> 00:24:17,319 longer than twenty four inches, right. 481 00:24:17,359 --> 00:24:18,319 Speaker 2: Well, they might. 482 00:24:18,200 --> 00:24:22,599 Speaker 3: Even run through a set of ganged studs and it 483 00:24:22,680 --> 00:24:24,680 might be twelve inches where that all of them run 484 00:24:24,759 --> 00:24:28,400 through that I'm just throwing things out there. That'd be okay, 485 00:24:28,640 --> 00:24:33,440 because that is not continuously longer than twenty four inches. 486 00:24:35,240 --> 00:24:37,160 So the moral of the story here is, if you're 487 00:24:37,200 --> 00:24:40,000 gonna run MC cables then we're gonna talk about MC's. 488 00:24:40,400 --> 00:24:42,319 But if you're going to run MC cables, and this again, 489 00:24:42,359 --> 00:24:47,200 this applies to any multiiconductor cable. Even though NM cable 490 00:24:47,200 --> 00:24:50,240 has its own rules about being in contact with thermal insulation, 491 00:24:50,480 --> 00:24:54,000 so does MC cable under three thirty four dot eighty 492 00:24:54,039 --> 00:24:58,079 four NM for nonmetallic and three point thirty dot eighty 493 00:24:58,119 --> 00:25:01,279 four MC even though they got their own rules for 494 00:25:01,400 --> 00:25:05,799 being in contact with thermal insulation. Okay, that will send 495 00:25:05,799 --> 00:25:09,119 you back here and you have to go to the table. 496 00:25:09,160 --> 00:25:11,000 So it sends you directly to the table, so you 497 00:25:11,000 --> 00:25:13,720 don't get to use the allowances that we're going to 498 00:25:13,720 --> 00:25:16,559 talk about in a minute for the thermal insulation contact 499 00:25:17,000 --> 00:25:20,119 here is different because this is just saying multiiconductor cables 500 00:25:20,160 --> 00:25:22,400 in general. So it could be trade cable, it could 501 00:25:22,440 --> 00:25:25,240 be NM cable, it could be MC cable, it could 502 00:25:25,279 --> 00:25:28,519 be AC cable, could be SEE cable. Those are all 503 00:25:29,119 --> 00:25:34,599 multiconductor cables, okay, multiconductor being two or more okay. And 504 00:25:34,680 --> 00:25:37,720 they're not installed in a raceway okay. So they're following 505 00:25:37,759 --> 00:25:41,119 their uses permitted rules dot ten of their specific wiring 506 00:25:41,119 --> 00:25:41,799 method and they're. 507 00:25:41,680 --> 00:25:44,519 Speaker 2: Being installed, but they're being installed in a. 508 00:25:44,480 --> 00:25:52,119 Speaker 3: Way that they're touching continuously for over twenty four inches. Now, 509 00:25:52,160 --> 00:25:54,839 I can tell you where I've seen this take place 510 00:25:54,960 --> 00:25:58,200 that had devastating effects, and this was in a grow 511 00:25:58,279 --> 00:26:01,880 house that was a regular dwelling, and I can't remember. 512 00:26:01,920 --> 00:26:04,079 I think it was in Colorado when they changed over 513 00:26:04,400 --> 00:26:06,480 and you had a house. It was a regular dwelling 514 00:26:06,519 --> 00:26:09,279 that was gutted pretty much, but it was used as 515 00:26:09,319 --> 00:26:12,720 a grow house. And they used what they did an 516 00:26:12,759 --> 00:26:15,759 installation practice where they bought all of their INM cables 517 00:26:15,799 --> 00:26:18,240 together like a trunk line, and then they tie wrapped 518 00:26:18,240 --> 00:26:18,640 them together. 519 00:26:18,680 --> 00:26:20,359 Speaker 2: It could do the same thing for MC whatever. 520 00:26:20,400 --> 00:26:22,759 Speaker 3: They thought that looked better because it was neaterter They're 521 00:26:22,759 --> 00:26:26,119 all running down the same way, and everything looked uniform. 522 00:26:26,200 --> 00:26:26,839 Speaker 2: They looked neat. 523 00:26:28,079 --> 00:26:32,160 Speaker 3: But the problem was now that they changed the loading conditions, 524 00:26:32,359 --> 00:26:34,559 the type of loading, it wasn't as diverse as it 525 00:26:34,640 --> 00:26:37,279 was with a dwelling. Now those conductors are caring much 526 00:26:37,319 --> 00:26:41,519 more current and in this scenario because they were bundled 527 00:26:42,039 --> 00:26:45,559 and they were installed where they were not maintaining spacing, 528 00:26:47,039 --> 00:26:50,480 and so in that point they were bundled for length 529 00:26:50,839 --> 00:26:54,400 longer than twenty four inches. They start the heat couldn't 530 00:26:54,400 --> 00:26:56,960 dissipate out of it. Even if it wasn't loading them 531 00:26:56,960 --> 00:27:00,079 to their full extent, the cables that were inside of 532 00:27:00,119 --> 00:27:03,519 the bundle couldn't dissipate the heat adequate and it caused 533 00:27:03,519 --> 00:27:06,640 the breakdown and it caused fires. And not to mention, 534 00:27:06,759 --> 00:27:09,599 they also through these in thermal insulations because that affects 535 00:27:09,599 --> 00:27:11,680 it as well. But at the end of the day, 536 00:27:12,680 --> 00:27:17,920 bundling was in effect because they were not maintaining the spacing, 537 00:27:17,960 --> 00:27:21,440 and of course probably never caused an issue because of 538 00:27:21,519 --> 00:27:24,400 diversity in the dwelling, even though the code is what 539 00:27:24,440 --> 00:27:27,880 it is, But it's the moment that they changed the 540 00:27:27,920 --> 00:27:30,400 condition of use, the loading what was going on in 541 00:27:30,440 --> 00:27:34,119 that building and without changing the wiring created a problem 542 00:27:34,200 --> 00:27:35,079 and it caused a fire. 543 00:27:35,400 --> 00:27:38,279 Speaker 2: Okay, so the rules are here for a reason. 544 00:27:39,599 --> 00:27:44,039 Speaker 3: Now it also goes on to say that that we 545 00:27:44,079 --> 00:27:48,000 can put so it actually says each current carrying conductor 546 00:27:48,079 --> 00:27:51,519 in a parallel set of conductors shall be counted as 547 00:27:51,680 --> 00:27:56,039 current carrying conductor. Okay, So if I have multiple sets 548 00:27:56,160 --> 00:28:01,079 for example, ABC, ABC, ABC, then again, and each current 549 00:28:01,119 --> 00:28:03,559 carent conductor in the sets, you know, the a's, the 550 00:28:03,599 --> 00:28:06,160 b the c's, they're all considered current current conductors. Now, 551 00:28:06,920 --> 00:28:09,519 if you go down and you look at the allowances 552 00:28:09,640 --> 00:28:11,880 under C one, you'll have an A, A B, A C, 553 00:28:12,000 --> 00:28:16,319 and a D. We're going to be focusing on D, okay, 554 00:28:16,400 --> 00:28:19,519 because you do have some allowances. For example, when you're 555 00:28:19,640 --> 00:28:23,720 running underground conductors, you have some allowances. 556 00:28:23,759 --> 00:28:25,400 Speaker 2: When you're talking about. 557 00:28:25,000 --> 00:28:30,400 Speaker 3: A raceway that is uh not exceeding twenty four inches, 558 00:28:30,400 --> 00:28:33,480 which people want to call a nipple. Chapter nine, Table 559 00:28:33,519 --> 00:28:37,000 one refers you know, refers to things like nipples. But again, 560 00:28:37,039 --> 00:28:40,359 I don't like that terminology. It's still just a raceway, okay, 561 00:28:40,440 --> 00:28:42,759 whether it's twenty four inches or not, it's still a raceway. 562 00:28:43,279 --> 00:28:43,720 Speaker 2: So I don't know. 563 00:28:43,759 --> 00:28:46,119 Speaker 3: I like the term nipple, but it doesn't use nipple here, 564 00:28:46,319 --> 00:28:47,720 so that's good, right. 565 00:28:47,759 --> 00:28:48,799 Speaker 2: And then of course, any. 566 00:28:48,599 --> 00:28:50,480 Speaker 3: Conductors that are installed in cable trades, you're going to 567 00:28:50,519 --> 00:28:53,240 follow the rules in six ninety two eighty uh for 568 00:28:53,480 --> 00:28:57,440 cable trade applications, and you got stacking and spacing and 569 00:28:57,480 --> 00:28:59,640 all these other rules that you have to follow for 570 00:28:59,759 --> 00:29:03,599 k if you're going to install single insulated conductors in 571 00:29:03,640 --> 00:29:08,079 cable trays. But we're focusing on the allowance for or 572 00:29:08,119 --> 00:29:12,519 AC cable because it probably is the most predominant application 573 00:29:12,599 --> 00:29:15,079 of MC cable and commercial buildings. I can tell you 574 00:29:15,240 --> 00:29:18,839 is on co wire, we produce a lot of twelve 575 00:29:18,880 --> 00:29:21,880 to MC cable. I mean a lot, I mean over 576 00:29:21,920 --> 00:29:24,680 one hundred machines that run twenty four to seven a 577 00:29:25,000 --> 00:29:27,519 year round, probably break for Christmas and New Year's but 578 00:29:27,640 --> 00:29:31,559 other than that, it runs all the time. And it's 579 00:29:31,599 --> 00:29:35,279 because you have the lighting loads and commercial receptacle loads 580 00:29:35,319 --> 00:29:37,599 and commercial and majority of all that is twelve gage 581 00:29:38,240 --> 00:29:41,680 and the vast majority of this is a simple twelve 582 00:29:41,720 --> 00:29:44,759 two okay, which does not have more than three current 583 00:29:44,799 --> 00:29:45,400 carent conductors. 584 00:29:45,400 --> 00:29:47,200 Speaker 2: There's two current carrying conductors in there. 585 00:29:47,960 --> 00:29:51,440 Speaker 3: So one of the things that I also again to 586 00:29:51,599 --> 00:29:55,880 not be redundant is I remind people when is a 587 00:29:55,960 --> 00:29:59,839 neutral considered current carrying You should take some time in 588 00:30:00,039 --> 00:30:02,799 go to three TENOT fifteen and then go all the 589 00:30:02,839 --> 00:30:05,799 way down and look at E. And I'm in the 590 00:30:05,799 --> 00:30:08,039 twenty twenty three edition of the NEC by the way, 591 00:30:08,079 --> 00:30:11,279 So in case anything reference I make to you in 592 00:30:11,400 --> 00:30:14,640 code you're like, well, that's not in my code book. 593 00:30:14,680 --> 00:30:17,240 Well it's going to be somewhere around there, okay, depending 594 00:30:17,279 --> 00:30:19,039 on what cycle you're in. But I'm working in the 595 00:30:19,079 --> 00:30:21,319 twenty twenty three edition, and I'm always going to be 596 00:30:21,319 --> 00:30:24,279 in the latest published edition, regardless of where you are 597 00:30:24,319 --> 00:30:26,920 in the country. I'm always going to be teaching out 598 00:30:26,920 --> 00:30:28,720 of the twenty twenty three I can't go backwards. 599 00:30:28,720 --> 00:30:30,240 Speaker 2: I have to keep moving forwards. Okay. 600 00:30:31,160 --> 00:30:34,599 Speaker 3: Now, if you look at what's considered a neutral conductor 601 00:30:35,400 --> 00:30:39,359 and what would not be considered current caring, then you 602 00:30:39,480 --> 00:30:43,319 have conditions here. For example, the neutral conductor of a 603 00:30:43,400 --> 00:30:47,119 three two two phase conductors and a neutral that are 604 00:30:47,160 --> 00:30:49,640 derived from a four wire three phase. 605 00:30:49,720 --> 00:30:52,200 Speaker 2: Why, well, if that's what you're doing, So. 606 00:30:52,160 --> 00:30:55,319 Speaker 3: You're taking a four wire three phase system and you're 607 00:30:55,359 --> 00:30:59,279 breaking off of that to create a three wire where 608 00:30:59,319 --> 00:31:02,519 you have two two ungrounded hot conductors and a neutral. 609 00:31:03,200 --> 00:31:07,039 If that's the case, then that neutral is current carrying 610 00:31:07,480 --> 00:31:10,400 because it's going to carry approximately the same amount of 611 00:31:10,440 --> 00:31:13,480 current as the ligne to neutral load currents of the 612 00:31:13,720 --> 00:31:17,640 other conductors that are there. Okay, So when that takes place, 613 00:31:18,359 --> 00:31:21,519 then you have to apply three ten fifteen C one, 614 00:31:21,599 --> 00:31:23,480 so it's considered a current carent conductor. 615 00:31:23,519 --> 00:31:25,640 Speaker 2: The other condition would be. 616 00:31:25,480 --> 00:31:28,119 Speaker 3: If you have a four wire three phase y system 617 00:31:29,000 --> 00:31:32,599 and the majority of or the major portion of the 618 00:31:32,640 --> 00:31:35,640 loads consists of non linear loads. 619 00:31:36,039 --> 00:31:36,240 Speaker 2: Right. 620 00:31:36,279 --> 00:31:39,119 Speaker 3: If that's the case, then you got what's called harmonic currents, 621 00:31:39,119 --> 00:31:42,200 and the worst affected be tripling harmonics. Those are going 622 00:31:42,279 --> 00:31:46,119 to be presented onto the neutral, and therefore that neutral 623 00:31:46,119 --> 00:31:49,119 conductor is going to be considered a current carry conductor. 624 00:31:49,160 --> 00:31:53,039 So you have to know what your system is. In 625 00:31:53,119 --> 00:31:56,480 a simple two wire cable twelve two, then the neutral 626 00:31:56,640 --> 00:32:00,240 and the hot are both considered current carrent conductors. Out 627 00:32:01,039 --> 00:32:04,160 If I have two conductors that are sharing a neutral, 628 00:32:04,240 --> 00:32:08,119 it's a you know, basically, I've got a multi wire 629 00:32:08,160 --> 00:32:11,920 branch circuit and I've got two one twenty voult circuits 630 00:32:11,920 --> 00:32:14,599 that are sharing a neutral. Well, then that neutral is 631 00:32:14,680 --> 00:32:18,000 only carrying the unbalanced current from the other conductors and 632 00:32:18,039 --> 00:32:20,440 it's not to be counted when you're applying three ten 633 00:32:20,480 --> 00:32:21,359 dot fifteen C one. 634 00:32:21,480 --> 00:32:22,759 Speaker 2: So that's why you. 635 00:32:22,720 --> 00:32:24,160 Speaker 3: See, if I have a red and a black and 636 00:32:24,200 --> 00:32:27,200 it's doing a multi wire brand circuit, you follow all 637 00:32:27,279 --> 00:32:30,599 the requirements to do that and identified handle tie or 638 00:32:30,640 --> 00:32:33,240 on a two pole breaker so that you ensure that 639 00:32:33,359 --> 00:32:36,400 each one of the legs are on a separate leg 640 00:32:36,440 --> 00:32:38,799 coming into the panel. Then what you're going to have 641 00:32:38,880 --> 00:32:41,240 is a cancelation effect take place, and then of course 642 00:32:41,319 --> 00:32:44,559 then we do not have to count that neutral as 643 00:32:44,599 --> 00:32:46,880 a current carent conductor when it comes to following these 644 00:32:46,960 --> 00:32:50,599 rules at three ten dot fifteen. However, if I have 645 00:32:50,720 --> 00:32:54,279 a three phase system and it's a multi wire brand circuit, 646 00:32:54,480 --> 00:32:58,240 and I have a neutral, but that neutral is basically 647 00:32:59,279 --> 00:33:02,079 dealing in a situation where it's supplying loads that are 648 00:33:02,079 --> 00:33:05,680 non linear loads like fluorescent lighting, then I have to 649 00:33:05,680 --> 00:33:10,559 be careful because then you've got what non linear loads 650 00:33:10,599 --> 00:33:14,400 fluorescent would be like that it's carrying non linear loads, 651 00:33:15,119 --> 00:33:18,880 then what happens, Well, then you've got current that is 652 00:33:18,920 --> 00:33:23,440 traveling on the neutral, probably equal to any of the others, 653 00:33:24,079 --> 00:33:26,880 any of the other ungrounded conductors to the neutral. 654 00:33:27,519 --> 00:33:29,960 Speaker 2: So what happens is you have to treat it as 655 00:33:30,359 --> 00:33:31,559 a current current conductor. 656 00:33:31,599 --> 00:33:34,039 Speaker 3: So these are things that you have to think about 657 00:33:34,720 --> 00:33:38,559 when do I count that neutral, And if you do 658 00:33:38,720 --> 00:33:42,440 count it, it can play a major role in whether 659 00:33:42,519 --> 00:33:45,720 or not you can apply three ten do fifteen C 660 00:33:45,920 --> 00:33:48,480 one D. And so that's what we're going to talk about. 661 00:33:48,519 --> 00:33:52,079 So we're looking at three ten fifteen C one D 662 00:33:52,519 --> 00:33:55,559 and this is based also on the article that I 663 00:33:55,599 --> 00:33:58,680 wrote over on our website, So make sure you check 664 00:33:58,759 --> 00:34:02,599 out that article. If any of this becomes confusing, take 665 00:34:02,680 --> 00:34:04,480 some time go check it out. 666 00:34:04,720 --> 00:34:07,359 Speaker 2: Doesn't cost you anything, it's free, all right. So what 667 00:34:07,400 --> 00:34:08,280 are we talking about here? 668 00:34:08,320 --> 00:34:11,800 Speaker 3: So is there a condition where I'm running MC cable 669 00:34:12,239 --> 00:34:14,559 or I'm running AC cable, and let's say I am 670 00:34:14,639 --> 00:34:18,039 bundling it for more than twenty four inches, I'm not 671 00:34:18,159 --> 00:34:20,559 maintaining spacing continuously. 672 00:34:21,199 --> 00:34:23,079 Speaker 2: Okay, okay, So all right? 673 00:34:23,199 --> 00:34:27,480 Speaker 3: Is there a condition when I can apply this allowance 674 00:34:27,480 --> 00:34:29,880 where I can look at this adjustment factor and say, 675 00:34:30,000 --> 00:34:32,199 you know what, I don't want to deal with it. 676 00:34:32,480 --> 00:34:35,320 I don't want to have to apply the adjustment factor. Well, 677 00:34:35,320 --> 00:34:39,559 there is, but you have to meet specific conditions. There 678 00:34:39,559 --> 00:34:41,800 are four conditions to meet, and there is an exception 679 00:34:41,920 --> 00:34:44,440 to one of the conditions, but you have to meet them. 680 00:34:44,440 --> 00:34:46,119 Speaker 2: All okay, So let's look at it. 681 00:34:46,159 --> 00:34:48,719 Speaker 3: So, if you have your National Electrical Code, We're going 682 00:34:48,800 --> 00:34:51,760 to go again three ten fifteen C one D and 683 00:34:51,800 --> 00:34:55,679 I'm going to read it. It says adjustment factors shall 684 00:34:55,760 --> 00:35:00,360 not apply to type AC cable or to type MC 685 00:35:00,480 --> 00:35:04,039 cable under the following conditions. So what that means is 686 00:35:04,039 --> 00:35:07,239 you have to meet all of these conditions. Now we 687 00:35:07,280 --> 00:35:11,159 will give you an exception to one condition, but you 688 00:35:11,239 --> 00:35:14,000 still have to meet generally all the conditions that are 689 00:35:14,159 --> 00:35:15,679 in the scope of d Okay. 690 00:35:16,360 --> 00:35:19,039 Speaker 2: So what's the first thing that says? Okay? So let's 691 00:35:19,079 --> 00:35:19,840 assume in. 692 00:35:19,800 --> 00:35:23,760 Speaker 3: Our mind that we've got a situation where we have 693 00:35:25,119 --> 00:35:30,719 the twelve MC cables, and each one of those MC 694 00:35:30,840 --> 00:35:36,119 cables contain two current current conductors black and white, and 695 00:35:36,199 --> 00:35:40,079 so we have got twelve of them. And you don't 696 00:35:40,079 --> 00:35:43,960 blame the apprentice. You did it. You loaded it up. 697 00:35:44,199 --> 00:35:48,239 So let's see if we can use this allowance here, 698 00:35:48,480 --> 00:35:49,760 which is not an exception. 699 00:35:50,440 --> 00:35:52,079 Speaker 2: A lot of people call it an exception. 700 00:35:52,239 --> 00:35:55,599 Speaker 3: It's a provision because it doesn't say that this is 701 00:35:55,639 --> 00:35:58,559 an exception. It just it's a provision that you can 702 00:35:58,639 --> 00:36:03,559 utilize in here. So it says, first thing, it goes, okay, 703 00:36:04,039 --> 00:36:07,719 each cables do not have an overall outer covering. Okay, 704 00:36:07,880 --> 00:36:10,639 So this is three ten to fifteen, uh three ten 705 00:36:10,719 --> 00:36:15,480 fifteen C one D one and okay, so it's MC cable. 706 00:36:16,119 --> 00:36:20,000 It's not PVC jacket at MC, it's just MC cable. Okay, 707 00:36:21,000 --> 00:36:25,119 we have no jacket. Good there, We're good. The next 708 00:36:25,199 --> 00:36:29,039 caveat is that each cable shall have not more than 709 00:36:29,159 --> 00:36:32,400 three current carr and conductors. Well, if it did have 710 00:36:32,719 --> 00:36:34,480 if it did have more than three, then I couldn't 711 00:36:34,559 --> 00:36:36,400 use D and I just have to apply the adjustment 712 00:36:36,440 --> 00:36:39,159 factors like I would anything else. So we're trying to 713 00:36:39,199 --> 00:36:44,239 see if we can ignore the adjustment factors. Well, are cables, 714 00:36:44,280 --> 00:36:47,599 for example, which are twelve two which have two current 715 00:36:47,639 --> 00:36:50,480 carrent conductors. We're okay, we meet that item. So we 716 00:36:50,519 --> 00:36:53,960 meet D two not a problem. I had number three 717 00:36:54,159 --> 00:36:58,559 three says conductors are twelve copper. Okay, So this is 718 00:36:58,960 --> 00:37:02,679 very important to understand. There are people out there that say, 719 00:37:02,719 --> 00:37:06,079 you know what, what if I'm have a cables and 720 00:37:06,159 --> 00:37:11,679 I'm bundling them, but in that bundle of these twelves mcs, 721 00:37:11,840 --> 00:37:14,719 I also have some ten MC, maybe even some six 722 00:37:14,840 --> 00:37:18,360 MC that are in the same bundle. Can I isolate 723 00:37:18,400 --> 00:37:21,159 the twelves out and if I don't have more than 724 00:37:21,360 --> 00:37:23,719 well I'm getting ahead of myself. Can I treat each 725 00:37:23,800 --> 00:37:24,960 one of the bundles separate? 726 00:37:25,199 --> 00:37:25,320 Speaker 2: No. 727 00:37:25,480 --> 00:37:28,199 Speaker 3: If they're all bundled together, they're all putting off mutual heating, 728 00:37:28,400 --> 00:37:31,039 and they're all going to affect the opacity of their 729 00:37:31,079 --> 00:37:34,880 conductors in different ways for you to be able to 730 00:37:34,960 --> 00:37:37,760 use this adjust to ignore the adjustment factors. 731 00:37:37,760 --> 00:37:41,079 Speaker 2: Here, the rule is it has to be. 732 00:37:41,039 --> 00:37:44,239 Speaker 3: All twelve, okay, in order to do that, because even 733 00:37:44,239 --> 00:37:46,960 the tens or even the eights are going to add 734 00:37:47,400 --> 00:37:52,280 mutual heating over to these conductors. So the whole point 735 00:37:52,320 --> 00:37:57,960 here is that there's size twelve, okay, twelve gauge. The 736 00:37:58,000 --> 00:38:02,519 next one says, okay, so I have not more than 737 00:38:02,559 --> 00:38:04,239 if you have not more, so in our case we 738 00:38:04,280 --> 00:38:07,519 do have twelve games, so we're good. The next says, 739 00:38:08,119 --> 00:38:11,679 not more than twenty current carrying conductors are installed without 740 00:38:11,719 --> 00:38:16,280 maintaining spacing. That means, be honest with you if they're 741 00:38:16,800 --> 00:38:20,039 touching at any point. So once we get to this allowance, 742 00:38:20,440 --> 00:38:24,280 this provision in D, it's irrelevant the fact that we 743 00:38:24,440 --> 00:38:28,280 have the continuous without maintaining spacing for continuously for over 744 00:38:28,320 --> 00:38:33,280 twenty four inches. The assumption is we're down here because 745 00:38:34,239 --> 00:38:36,840 we have that issue. That's why we're down here. 746 00:38:37,360 --> 00:38:38,199 Speaker 2: Okay. 747 00:38:38,360 --> 00:38:41,320 Speaker 3: So in this scenario right here, it says, well, if 748 00:38:41,360 --> 00:38:44,039 you don't have more than twenty current current conductors installed 749 00:38:44,079 --> 00:38:50,400 without maintaining spacing, are stacked, or are supported on bridle rings, 750 00:38:51,440 --> 00:38:54,280 then you can say, okay, if I meet all of these, 751 00:38:55,039 --> 00:38:57,639 so I don't have the jacket, I don't have more 752 00:38:57,639 --> 00:39:01,000 than three current carent conductors. I am using twelve gauge, 753 00:39:01,079 --> 00:39:03,440 and I don't have more than twenty current CARR conductors. 754 00:39:03,480 --> 00:39:06,800 Guess what I get to ignore any of the adjustment 755 00:39:06,800 --> 00:39:10,079 factors even if I'm bundling that cable. Hell, I could 756 00:39:10,079 --> 00:39:14,679 bundle it for fifty feet MC cables as long as 757 00:39:14,719 --> 00:39:18,440 I have what no jacket, not more than three current 758 00:39:18,440 --> 00:39:21,559 current conductors, it's twelve gauge, and I don't have more 759 00:39:22,079 --> 00:39:26,480 the accumulation of conductors in this bundle. If I don't 760 00:39:26,519 --> 00:39:30,599 have more than twenty current carent conductors in summation, then 761 00:39:30,639 --> 00:39:33,840 I can just say forget about it and not worry 762 00:39:33,880 --> 00:39:35,119 about the adjustment factors. 763 00:39:36,519 --> 00:39:39,880 Speaker 2: That's a beautiful thing. Guys, think about how you're doing this. 764 00:39:41,719 --> 00:39:44,519 Speaker 3: Because it gives you the ability because a lot of 765 00:39:44,599 --> 00:39:47,480 times what you'll be doing is these twelves mcs are 766 00:39:47,480 --> 00:39:49,960 probably going to be due lighting in commercial buildings probably 767 00:39:49,960 --> 00:39:50,679 going to do lighting. 768 00:39:51,400 --> 00:39:53,719 Speaker 2: This lighting is going to be continuous loads. 769 00:39:54,119 --> 00:39:57,280 Speaker 3: Right, So when you're sizing the brand circuit to ten 770 00:39:57,360 --> 00:40:00,760 dot nineteen, you're sizing everything. If it's continuous load and 771 00:40:00,760 --> 00:40:03,000 one hundred and twenty five percent, so you've got to 772 00:40:03,039 --> 00:40:06,679 take all that in consideration. And lighting is continuously for 773 00:40:06,719 --> 00:40:09,719 three hours and more a maximum output whatever it's lamped at, 774 00:40:10,679 --> 00:40:16,039 so it can make a major impact on sizing conductors 775 00:40:16,079 --> 00:40:18,320 and which load you can have on something. So if 776 00:40:18,320 --> 00:40:21,760 you had to adjust it and start lowing that apacity, 777 00:40:22,440 --> 00:40:25,239 then you could end up with a conductor that after 778 00:40:25,239 --> 00:40:27,920 the end of the day, after all that work, does 779 00:40:27,960 --> 00:40:31,159 not have the apacity capable of handling whatever load you 780 00:40:31,199 --> 00:40:35,039 needed to handle, And that becomes a big headache, especially 781 00:40:35,079 --> 00:40:39,000 if you're it's not detected until the end of the 782 00:40:39,079 --> 00:40:42,920 job and you're going, well, why didn't the inspector find 783 00:40:42,920 --> 00:40:45,280 that out? Well, that's your responsibility, not the inspectors. They 784 00:40:45,320 --> 00:40:47,480 may miss it, they may not account it that they 785 00:40:47,519 --> 00:40:50,000 trusted you. They're not going to sit there and go 786 00:40:50,079 --> 00:40:52,360 through every single thing account I mean, they don't have 787 00:40:52,360 --> 00:40:56,280 the time for that. It's always going to be your responsibility, 788 00:40:56,639 --> 00:41:00,360 always your responsibility to make sure it's done right. Now, 789 00:41:02,719 --> 00:41:06,599 if I'm in this situation here and I've got let's say, 790 00:41:07,559 --> 00:41:10,159 let me give you one scenario that we give this 791 00:41:10,199 --> 00:41:14,280 scenario in are what's called practical application. What happens if, again, 792 00:41:14,360 --> 00:41:17,000 I have cables that are twelves and tens all together 793 00:41:17,039 --> 00:41:20,559 in the bundle. Okay, Well, if that's the case, then 794 00:41:20,679 --> 00:41:26,880 you cannot use this allowance and you cannot use the exception. 795 00:41:28,519 --> 00:41:33,320 Why because the exception is very clear on what you 796 00:41:33,440 --> 00:41:33,960 have to meet. 797 00:41:34,239 --> 00:41:34,760 Speaker 2: You have to. 798 00:41:34,679 --> 00:41:38,000 Speaker 3: Still meet one, two, and three in order to be 799 00:41:38,039 --> 00:41:39,440 able to even use the exception. 800 00:41:40,039 --> 00:41:41,920 Speaker 2: So what is the exception? Okay, I just gave you 801 00:41:41,960 --> 00:41:42,440 an example. 802 00:41:42,480 --> 00:41:43,920 Speaker 3: I was going to talk about ten and twelves, but 803 00:41:43,960 --> 00:41:46,639 I'll use this while I'm looking at the exception. 804 00:41:46,679 --> 00:41:48,760 Speaker 2: So I'll make it easy. Let's look at the exception. 805 00:41:48,840 --> 00:41:52,599 Speaker 3: So what if I happen to have more than twenty 806 00:41:52,760 --> 00:41:57,159 current current conductors? The apprentice will blame the apprentice. It's 807 00:41:57,199 --> 00:41:59,719 always on you because you're the master or the journeyman. 808 00:41:59,719 --> 00:42:01,800 They don't overseas it, but we'll blame the apprentice because 809 00:42:01,800 --> 00:42:02,920 it's just the easy thing to do. 810 00:42:03,000 --> 00:42:03,199 Speaker 2: Right. 811 00:42:03,880 --> 00:42:07,920 Speaker 3: So they happen to throw eleven or even twelve MC's 812 00:42:08,079 --> 00:42:12,079 in the bridle rings or in the bundle and they're 813 00:42:12,079 --> 00:42:16,639 not maintaining spacing, Okay, then you're like, oh, well, crap, 814 00:42:18,320 --> 00:42:20,840 what do I do? Now, because that takes you out 815 00:42:20,920 --> 00:42:24,800 of the ability to use this allowance here, and that 816 00:42:24,840 --> 00:42:28,360 would ultimately send your butt down to using the table 817 00:42:28,920 --> 00:42:32,440 three ten fifteen C one. And if we have got, 818 00:42:32,440 --> 00:42:36,760 for example, eleven m season there with twelve twos in 819 00:42:36,800 --> 00:42:38,800 each one and we got eleven so now that's twenty 820 00:42:38,840 --> 00:42:45,239 two current carr and conductors, well we have over twenty 821 00:42:45,280 --> 00:42:47,480 and we're like, oh crap. So if we didn't have 822 00:42:47,559 --> 00:42:50,320 an exception, then we would come down here and look 823 00:42:50,360 --> 00:42:53,039 and say, well, damn, if it's twenty one to thirty, 824 00:42:53,559 --> 00:42:59,039 that's going to drop it to forty five as a multiplier. Well, 825 00:42:59,400 --> 00:43:03,039 what what does exception say? Well, this exception says, you 826 00:43:03,079 --> 00:43:07,599 know what, if your cables meet the requirements of three 827 00:43:07,719 --> 00:43:10,960 ten fifteen C one D one and that is the 828 00:43:11,039 --> 00:43:14,679 one about not having a jacket on it through C 829 00:43:14,800 --> 00:43:17,280 one D three, which means it also doesn't have more 830 00:43:17,320 --> 00:43:20,360 than three current carry conductors in each cable and the 831 00:43:20,400 --> 00:43:23,119 conductors are twelve gauge, so I had to meet all 832 00:43:23,199 --> 00:43:25,679 three of these. So the twelve gates is a trigger 833 00:43:25,719 --> 00:43:29,360 here if that is a case, if you have more 834 00:43:29,400 --> 00:43:33,679 than twenty current carent conductors are installed longer than twenty 835 00:43:33,719 --> 00:43:39,400 four inches without maintaining spacing, are stacked or are supported. 836 00:43:38,880 --> 00:43:40,280 Speaker 2: On bridal rings. 837 00:43:41,000 --> 00:43:46,760 Speaker 3: It says a sixty percent adjustment factor shall be applied. Well, 838 00:43:46,800 --> 00:43:49,239 I can tell you right now you're far better to 839 00:43:49,320 --> 00:43:53,079 apply a sixty percent than to that scenario with the 840 00:43:53,639 --> 00:43:56,239 twenty two current car conductors than it is for you 841 00:43:56,280 --> 00:44:00,639 to have to apply a forty five. Make a huge difference. 842 00:44:01,039 --> 00:44:04,079 So we're assuming that this is MC. We'll assume that 843 00:44:04,119 --> 00:44:08,079 the conductor's inside of it are rated ninety degrees thhn, 844 00:44:08,239 --> 00:44:11,119 we just go with that assumption. The code allows me 845 00:44:11,199 --> 00:44:15,239 to adjust from the higher opacity conductor, so I'd adjust 846 00:44:15,280 --> 00:44:18,239 it from the ninety degree twelve gauge good for thirty amps. 847 00:44:18,639 --> 00:44:22,280 If I do it at forty five multiplier based on 848 00:44:22,320 --> 00:44:24,159 the table, then it gives me like a conductor that's 849 00:44:24,199 --> 00:44:26,280 good for thirteen point five amps. 850 00:44:26,559 --> 00:44:27,239 Speaker 2: That sucks. 851 00:44:28,159 --> 00:44:30,320 Speaker 3: But if I use the sixty percent, I believe it 852 00:44:30,320 --> 00:44:32,840 gives me a conductor. If you multiply from the thirty 853 00:44:33,119 --> 00:44:36,480 I believe it gives me an opacity of eighteen amps, 854 00:44:37,159 --> 00:44:41,280 which means that hey, for lighting applications, it may be 855 00:44:41,639 --> 00:44:44,599 okay for me to be able to utilize it right 856 00:44:44,719 --> 00:44:47,119 and still be able to keep going and doing what 857 00:44:47,159 --> 00:44:49,719 I'm doing. And now I have a conductor that again, 858 00:44:50,280 --> 00:44:52,760 as long as the load doesn't exceed eighteen amps, can 859 00:44:52,800 --> 00:44:55,960 I terminate that on a twenty amp overcurrent device. Absolutely, 860 00:44:56,039 --> 00:44:59,960 So I still get a twenty amp circuit based on 861 00:45:00,039 --> 00:45:02,039 on the rating of the overcurrent device. So I still 862 00:45:02,079 --> 00:45:05,840 meet that, especially if it's a circuit to a load 863 00:45:05,880 --> 00:45:09,559 that demands that it be a twenty amp rated circuit. 864 00:45:10,039 --> 00:45:13,760 So it's still at twenty amps. Now my load can't 865 00:45:13,760 --> 00:45:19,239 exceed eighteen amps. Right, But at the end of the day, 866 00:45:19,519 --> 00:45:21,199 when you're looking at it, you're like, at least I 867 00:45:21,239 --> 00:45:24,199 have something to work with, and it still can be 868 00:45:24,280 --> 00:45:27,960 protected at twenty amp overcurrent protected device, and we're okay, okay, 869 00:45:29,679 --> 00:45:31,920 and we meet the rules also in two ten dot 870 00:45:31,960 --> 00:45:35,239 twenty for the overcurrent protection for continuous loads. 871 00:45:35,559 --> 00:45:36,639 Speaker 2: Okay, that type of scenario. 872 00:45:36,840 --> 00:45:41,119 Speaker 3: So's it's one of those things that you're still going 873 00:45:41,199 --> 00:45:43,239 to be okay, But the moment you have to use 874 00:45:43,280 --> 00:45:44,639 that forty five, you're screwed. 875 00:45:45,519 --> 00:45:47,000 Speaker 2: Now, why don't I bring that up again. 876 00:45:47,079 --> 00:45:49,159 Speaker 3: Let's go back to the exist, go to my example 877 00:45:49,679 --> 00:45:53,800 of mixing twelves and tens. Right, So if I had 878 00:45:53,840 --> 00:45:57,280 ten MC cables with twelve conductor in it. Okay, then 879 00:45:57,320 --> 00:46:01,079 that's twenty current current conductors of twelve. Then I have 880 00:46:01,119 --> 00:46:04,320 four MC's in the bundle that have ten gauged. Again, 881 00:46:04,400 --> 00:46:07,440 two current carrent conductors in each cable, and that ends 882 00:46:07,519 --> 00:46:09,880 up with eight, so I have a total of twenty 883 00:46:09,960 --> 00:46:14,559 eight current carring conductors. Well, because the bundle includes tens, 884 00:46:15,639 --> 00:46:18,760 they do not meet the criteria of three ten, fifteen 885 00:46:18,840 --> 00:46:22,599 C one D because this whole criteria was based on 886 00:46:22,639 --> 00:46:25,360 twelve gauges, and you treat the bundle as a bundle 887 00:46:25,599 --> 00:46:28,400 because those tens are going to be putting off heat 888 00:46:28,480 --> 00:46:32,559 that's going to be affected by what they're going to 889 00:46:32,559 --> 00:46:36,880 be affecting those the opacity of those twelve gauge conductors. Now, 890 00:46:36,960 --> 00:46:40,679 the exception was for you to have over twenty, but 891 00:46:40,840 --> 00:46:43,360 then as you read it, it required the conductors to 892 00:46:43,440 --> 00:46:46,519 still be twelve. So that means you can't even use 893 00:46:46,559 --> 00:46:50,119 the exception because it demands the use of the exception 894 00:46:50,239 --> 00:46:51,719 that it has to meet the rules in one, two, 895 00:46:51,760 --> 00:46:54,119 and three. That means the conductors all in this bundle 896 00:46:54,840 --> 00:46:57,199 have to be twelve gauge. So the fact that you 897 00:46:57,320 --> 00:47:01,119 got ten gauge cables in there he moves your ability 898 00:47:01,159 --> 00:47:05,559 to use anything in this allowance of three ten fifteen 899 00:47:05,599 --> 00:47:06,159 C one D. 900 00:47:06,679 --> 00:47:08,360 Speaker 2: So what do you end up having to do? Well, 901 00:47:08,440 --> 00:47:09,000 you screwed. 902 00:47:09,440 --> 00:47:11,760 Speaker 3: You have to treat them as twenty eight current care 903 00:47:11,800 --> 00:47:14,519 and conductors, and you're gonna have to apply the forty 904 00:47:14,679 --> 00:47:17,480 the multiplier forty five from the table three ten fifteen 905 00:47:17,559 --> 00:47:20,599 C one and you're gonna apply it to the opacities 906 00:47:20,639 --> 00:47:22,800 of the twelves, and you're gonna apply it to the 907 00:47:22,800 --> 00:47:24,159 opacities of the tens. 908 00:47:24,800 --> 00:47:27,079 Speaker 2: And that's just your new opacity. 909 00:47:27,199 --> 00:47:30,320 Speaker 3: And again it may drop you, probably will drop you 910 00:47:30,360 --> 00:47:35,760 below any usable value, especially with the twelve gage. So 911 00:47:37,320 --> 00:47:41,079 it's so important to understand how these rules are applied. 912 00:47:41,960 --> 00:47:45,239 And again the bundling part of it can be something 913 00:47:45,280 --> 00:47:48,679 that we can argue until the sun goes down and 914 00:47:48,719 --> 00:47:50,960 the sun comes up and your AHJ's got to make 915 00:47:50,960 --> 00:47:56,000 the call. But in the general charging rule, it's very 916 00:47:56,039 --> 00:47:59,800 clear that if they are bundled together doesn't say bundling, 917 00:48:00,199 --> 00:48:03,320 but they are installed together without maintaining spacing, which is 918 00:48:03,360 --> 00:48:09,079 slang for bundling continuously length longer than twenty four inches, 919 00:48:10,119 --> 00:48:13,119 then you're going to have to apply the adjustment factors. 920 00:48:14,360 --> 00:48:15,920 Speaker 2: The allowance under. 921 00:48:15,800 --> 00:48:21,039 Speaker 3: D is simply saying, you know what, I get their bundled, 922 00:48:22,199 --> 00:48:24,480 whether they're bundled one inch in this case or the 923 00:48:24,599 --> 00:48:26,599 over twenty four, I get it, they're bundled. So you're 924 00:48:26,639 --> 00:48:29,960 coming to me to find some relief. Okay, Well, I'm 925 00:48:29,960 --> 00:48:30,800 gonna give you some. 926 00:48:30,719 --> 00:48:32,800 Speaker 2: Relief as long as there's no jacket on it. 927 00:48:32,880 --> 00:48:34,840 Speaker 3: There's not more than three current current conductors, and the 928 00:48:34,840 --> 00:48:37,599 conductors are twelve gauge and you have not more than 929 00:48:37,639 --> 00:48:39,760 twenty boom, I'm gonna give you some relief. 930 00:48:42,159 --> 00:48:42,599 Speaker 2: You get me. 931 00:48:44,760 --> 00:48:46,880 Speaker 3: And then next thing they're gonna go is, well, you 932 00:48:46,880 --> 00:48:50,519 know what if you happen to have over twenty and 933 00:48:50,599 --> 00:48:54,119 you have over twenty and you still meet rule, you 934 00:48:54,159 --> 00:48:57,440 know the requirements of one, two, and three, then I'm 935 00:48:57,480 --> 00:49:00,159 gonna let you get away with it. But here, you know, 936 00:49:00,159 --> 00:49:03,840 here's the caveat. Okay, here's the caveat. I'm going to 937 00:49:03,960 --> 00:49:06,480 let you do what. I'm going to let you use 938 00:49:06,599 --> 00:49:10,880 sixty percent rather than the forty five percent, and that's 939 00:49:10,920 --> 00:49:13,599 going to save your butt in some cases. But in 940 00:49:13,679 --> 00:49:19,800 order to use this exception, it has to be twelve. Now, 941 00:49:19,800 --> 00:49:21,599 there are some people out there that will say, I'm 942 00:49:21,599 --> 00:49:23,360 sure there are that will say no. You know what, 943 00:49:23,920 --> 00:49:26,239 if I don't have more than twenty of the twelves 944 00:49:26,599 --> 00:49:29,440 and then I have the tens, then I can treat 945 00:49:29,480 --> 00:49:32,639 each separately. So I can apply this allowance to the 946 00:49:32,960 --> 00:49:36,320 twelves because it's not more than twenty. But then I 947 00:49:36,760 --> 00:49:41,360 apply the general rule to the tens, okay, using the 948 00:49:41,400 --> 00:49:43,800 summation of all the conductors, so it'd be twenty eight 949 00:49:43,880 --> 00:49:47,480 current current conductors, and apply the forty five percent to 950 00:49:47,679 --> 00:49:52,400 the tens. But I'm okay to ignore those that are 951 00:49:52,440 --> 00:49:54,639 bundled that are not more than twenty. But that's not 952 00:49:54,760 --> 00:49:59,639 really what the code says here. That bundle is treated 953 00:49:59,760 --> 00:50:03,400 as one because it puts off mutual heating because you're bundling, 954 00:50:03,920 --> 00:50:07,159 and that's going to affect the opacities of those twelves. 955 00:50:08,599 --> 00:50:12,079 So at the end of the day, you know whether 956 00:50:12,119 --> 00:50:16,760 they were tens or more twelves, does it matter. There's 957 00:50:16,800 --> 00:50:21,519 still more than twenty current current conductors in that bundle, right, 958 00:50:22,159 --> 00:50:25,840 And if that is the case overall bundle, then that's 959 00:50:25,880 --> 00:50:29,360 the case if you want to apply the exception, then 960 00:50:29,400 --> 00:50:32,199 it makes it very clear that its exception only will 961 00:50:32,239 --> 00:50:35,840 apply if they're twelve gauge, and that is why the 962 00:50:35,880 --> 00:50:38,599 exception references one, two, and three. So whatever you want 963 00:50:38,639 --> 00:50:41,119 to make up in your mind and think that number 964 00:50:41,119 --> 00:50:44,800 four allows you to isolate out the twelves from the 965 00:50:44,840 --> 00:50:47,440 tens in a multiple bundle where you have different sizes, 966 00:50:48,000 --> 00:50:50,360 then it kind of doesn't make sense when exception four 967 00:50:50,480 --> 00:50:54,199 ends up referencing that. Okay, well, to do this, it 968 00:50:54,280 --> 00:50:56,880 gives you the sixty percent you need to make sure 969 00:50:56,920 --> 00:51:01,360 there's still all twelves. You get what I'm saying, Okay, 970 00:51:01,840 --> 00:51:05,039 all right, and in order to apply at four not 971 00:51:05,159 --> 00:51:08,039 more than twenty, then that has. 972 00:51:07,920 --> 00:51:09,639 Speaker 2: To be twelves. Okay. 973 00:51:10,199 --> 00:51:13,159 Speaker 3: So anyway you interpreted how you want, that's how I 974 00:51:13,199 --> 00:51:15,320 look at it, and that's the only way to ensure 975 00:51:15,360 --> 00:51:17,880 that you're not going to break down that insulation. I 976 00:51:18,039 --> 00:51:22,679 encourage you to go over and read my blog because 977 00:51:22,719 --> 00:51:26,960 I also bring up an example of non simultaneously energized 978 00:51:27,000 --> 00:51:30,960 conductors that don't have to be counted as current carry conductors. 979 00:51:31,719 --> 00:51:33,519 And I give an example of that where I might 980 00:51:33,639 --> 00:51:36,679 have a raceway running to a piece of equipment that 981 00:51:36,840 --> 00:51:39,920 is basically has the air conditioning loads in the furnace loads, 982 00:51:40,159 --> 00:51:41,840 but neither one of them will be on at the 983 00:51:41,880 --> 00:51:44,559 same time. So there might be six conductors in that raceway, 984 00:51:44,599 --> 00:51:48,280 let's say, but only three of them at any given 985 00:51:48,320 --> 00:51:51,840 time will be energized. So I only have to count 986 00:51:51,880 --> 00:51:55,360 three rather than the total of six as current carry conductors, 987 00:51:55,400 --> 00:51:59,159 because these three for the furnace cannot be energized as 988 00:51:59,239 --> 00:52:02,480 the same time, let's say, as the other ones for 989 00:52:02,559 --> 00:52:04,000 the AC system. 990 00:52:04,159 --> 00:52:05,039 Speaker 2: You get what I'm saying. 991 00:52:05,440 --> 00:52:09,679 Speaker 3: So that is actually underneath the table in three ten 992 00:52:09,760 --> 00:52:10,239 fifteen c. 993 00:52:10,400 --> 00:52:12,679 Speaker 2: One. It is an asterisk. 994 00:52:13,199 --> 00:52:15,840 Speaker 3: It reminds you when it comes to the number of conductors, 995 00:52:15,920 --> 00:52:19,400 and it's the very last sentence. And so that may 996 00:52:19,559 --> 00:52:24,239 save some people if they're running conductors in a race 997 00:52:24,280 --> 00:52:28,360 way to a piece of equipment that cannot be They 998 00:52:28,440 --> 00:52:30,559 might be running to two pieces of equipment that cannot 999 00:52:30,559 --> 00:52:31,920 be energized at the same time. 1000 00:52:32,840 --> 00:52:37,079 Speaker 2: That may save somebody's butt. Okay. And also that. 1001 00:52:37,000 --> 00:52:39,800 Speaker 3: Note down there, or that that that asterix underneath it 1002 00:52:40,719 --> 00:52:44,920 also reminds you obviously that you're not going to be 1003 00:52:45,000 --> 00:52:47,840 using the grounding or bonding conductors as current carrying conductors. 1004 00:52:48,280 --> 00:52:50,840 People will argue, is but they carry fault current. Yes, 1005 00:52:50,960 --> 00:52:54,960 but they're not classified as current carrying conductors. Okay, so 1006 00:52:55,039 --> 00:52:57,159 they don't have to be counted as such. And where 1007 00:52:57,159 --> 00:53:02,119 do you see that three ten fifteen f Okay, go 1008 00:53:02,199 --> 00:53:05,840 read it, read it and weep in that type of thing. 1009 00:53:05,880 --> 00:53:08,519 So all right, all right, folks, that's about all I 1010 00:53:08,559 --> 00:53:10,920 probably wanted to talk about on today's episode. Hopefully got 1011 00:53:10,960 --> 00:53:12,760 something out of it.

And maybe I'm wrong, maybe 1021 00:53:37,599 --> 00:53:39,320 you think I'm interpreting something different. 1022 00:53:39,719 --> 00:53:42,719 Speaker 2: That's perfectly okay. I'm here to learn too, so okay, 1023 00:53:42,760 --> 00:53:43,639 I'm not a know it all. 1024 00:53:43,960 --> 00:53:46,280 Speaker 3: I'm just trying to give you some experience from thirty 1025 00:53:46,360 --> 00:53:49,000 nine years of working in the code where I develop 1026 00:53:49,079 --> 00:53:50,119 my opinions from. 1027 00:53:50,559 --> 00:53:53,320 Speaker 2: And so good.
