1 00:00:23,519 --> 00:00:38,479 Ask What Up? What Up? Everybody? Welcome to another episode of Let's 2 00:00:38,479 --> 00:00:42,960 Ask Paul, the podcast where you can ask me anything you want about the 3 00:00:43,039 --> 00:00:49,320 National Electrical Code, maybe electrical contracting, maybe just business advice. Again, 4 00:00:49,359 --> 00:00:53,719 I've failed, I've succeeded, but i have had my share of failures. 5 00:00:53,799 --> 00:00:58,880 So I've been in your shoes. So and I'm about as a candid as 6 00:00:58,920 --> 00:01:02,679 electric educator to you're gonna get Okay, I'm not hiding behind any facade. 7 00:01:02,799 --> 00:01:06,959 I do my best to be real with everybody.

It's academy that I'm ahead of, and we 15 00:01:38,480 --> 00:01:45,040 provide electrical code related education, not just for exam prep, for anybody wanting 16 00:01:45,040 --> 00:01:47,120 to take their game to the next level, whether you want to be more 17 00:01:47,239 --> 00:01:53,159 well rounded in residential code, electrical code, commercial electrical codes, industrial electrical 18 00:01:53,159 --> 00:01:57,560 codes, HVAC electrical code, and troubleshooting and things like that, how to 19 00:01:57,599 --> 00:02:02,079 address scenarios when you go to a job and you're doing troubleshooting for HVAC electrical 20 00:02:02,319 --> 00:02:07,120 We have a program for that. If you didn't know grounding and bonding, 21 00:02:07,200 --> 00:02:12,039 even electrical theory, and if you're one of those guys that are extremely knowledgeable, 22 00:02:12,039 --> 00:02:15,560 then you might want to try tackling our course called the Magenta, which 23 00:02:15,639 --> 00:02:22,120 is Industrial electrical and it is intense. I'm talking engineering level intense. You 24 00:02:22,159 --> 00:02:24,879 know, you'll if you only learn ten percent of what's in that module, 25 00:02:24,919 --> 00:02:29,800 you're gonna come away far ahead of most people. It's it's very intense, 26 00:02:30,039 --> 00:02:34,080 and most of it confuses me too. So check that out on our website 27 00:02:34,080 --> 00:02:38,280 fast tracks system dot com.

Okay, all right, So today episode I 46 00:04:00,360 --> 00:04:05,120 had a question somebody sent in and and it's more of an opinion piece type 47 00:04:05,159 --> 00:04:09,080 of question they ask me. It said, Hey, Paul, love your 48 00:04:09,120 --> 00:04:14,159 podcasts, love what you do for the industry. I appreciate listening to your 49 00:04:14,240 --> 00:04:19,720 podcast on a daily basis. I wanted to ask you of the changes in 50 00:04:19,800 --> 00:04:26,079 the twenty twenty three National Electrical Code, what do you think is your most 51 00:04:26,319 --> 00:04:30,480 favorite change? Thank you again, keep up the great work. Okay, 52 00:04:30,680 --> 00:04:36,399 great, great question. I appreciate the question came in. I also appreciate 53 00:04:36,600 --> 00:04:40,639 now and then when people aren't just asking me code questions. But you know, 54 00:04:40,720 --> 00:04:43,720 it's like a yo, yo, want my opinion. Everybody knows I'm 55 00:04:43,759 --> 00:04:48,480 opinionated. I'll give an opinion. But okay, So as an educator, 56 00:04:48,839 --> 00:04:56,079 I have to say, okay, I have to say that the restructuring of 57 00:04:56,279 --> 00:05:00,560 Article two twenty, which started out not being a big fan of, Okay, 58 00:05:00,600 --> 00:05:03,040 i'm gonna tell you that. Right, all of that I thought, 59 00:05:03,120 --> 00:05:08,120 okay, why are you gonna break something? I get it. But the 60 00:05:08,279 --> 00:05:10,639 more I got into it, and I mean, there's a lot of great 61 00:05:10,720 --> 00:05:15,079 changes that took place in the twenty twenty three edition of the n EC, 62 00:05:16,199 --> 00:05:25,160 but the restructuring the style of Article two twenty, to me, was brilliant. 63 00:05:26,759 --> 00:05:30,279 It flows so much better. Uh. And as a person that has 64 00:05:30,319 --> 00:05:36,959 to teach people calculations, low calculations and things like that it's it's it's just 65 00:05:38,120 --> 00:05:41,519 a much better flow than it was in the pat not that it was anything 66 00:05:41,600 --> 00:05:44,360 wrong with the twenty twenty the twenty seventeen. I mean, we can get 67 00:05:44,399 --> 00:05:47,439 there, right, we can get there, but it just flows. It 68 00:05:47,560 --> 00:05:53,439 just seems to flow so much better in the tent the twenty twenty three edition. 69 00:05:54,519 --> 00:05:57,279 And so if you had your codebook and you had a twenty twenty three, 70 00:05:58,240 --> 00:06:02,000 you'll notice that article two twenty has a new illustration at the beginning where 71 00:06:02,040 --> 00:06:04,560 the scope is and you should always read the scope so you know that what 72 00:06:04,639 --> 00:06:12,879 you're doing is Germane. But now it pretty is pretty much a really good 73 00:06:13,040 --> 00:06:17,439 pictogram if you will, of how it flows your general requirements in part one, 74 00:06:17,920 --> 00:06:21,120 your brand circuit load calculations in Part two, and how they flow and 75 00:06:21,279 --> 00:06:28,279 feed into Part three or Part four, and how the feeder or service load 76 00:06:28,360 --> 00:06:31,319 calculations, whether it's the standard or optional or going to use values that may 77 00:06:31,439 --> 00:06:36,079 come from Part two when you're coming up with your different loads, and it 78 00:06:36,199 --> 00:06:42,519 just seems to be a much easier flow, and it makes it really clear, 79 00:06:43,279 --> 00:06:48,000 for example, that when you're doing standard calculations that when you're dealing with 80 00:06:48,120 --> 00:06:53,680 healthcare facilities, or you're doing with Marina's boatyards, floating buildings, commercial and 81 00:06:53,759 --> 00:06:57,759 non commercial docking, that they're going to follow the standard method. There is 82 00:06:57,839 --> 00:07:02,720 no real optional method for them. So it's just a much easier way to 83 00:07:02,800 --> 00:07:08,439 look at it. And it makes it very clear that your neutral loads get 84 00:07:08,560 --> 00:07:12,680 calculated on the standard method, regardless of whether you're using the optional standard to 85 00:07:12,759 --> 00:07:15,759 size your feeder or service on grounded conductors. When it comes to the neutral 86 00:07:15,759 --> 00:07:18,839 you're gonna have to use the standard method. They both agree that two twenty 87 00:07:18,879 --> 00:07:21,160 dot sixty one, which is going to reference you back to the standard, 88 00:07:23,519 --> 00:07:26,680 is all applicable, So it just kind of it just gives you a much 89 00:07:26,959 --> 00:07:31,560 much better flow to it. Okay for me, for me anyway, in 90 00:07:31,600 --> 00:07:36,000 my opinion. Now, one of the things that kind of moved around and 91 00:07:36,120 --> 00:07:41,279 here also is when you're coming up to calculations and two twenty dot five you 92 00:07:41,360 --> 00:07:43,920 have now an A, B and a C, and C talks about the 93 00:07:43,959 --> 00:07:49,600 floor areas, so that got stripped out previously of two twenty dot twelve and 94 00:07:49,720 --> 00:07:54,680 all that kind of stuff when it comes to and into twenty dot fourteen, 95 00:07:55,439 --> 00:07:59,639 when it comes to what are the dimensions you use in order to come up 96 00:07:59,639 --> 00:08:03,839 with your floor area. So that is two twenty five C. Interesting enough, 97 00:08:03,959 --> 00:08:07,040 one of the things that I do get comments all the time, and 98 00:08:07,079 --> 00:08:11,319 a lot of my students who when they're doing their low calculations, you know, 99 00:08:11,360 --> 00:08:15,519 they're always rounding up kWh and things like that, and I have to 100 00:08:15,639 --> 00:08:20,759 remind them that the rounding rule that falls under two twenty dot five B. 101 00:08:20,959 --> 00:08:24,480 And remember I'm looking at the twenty twenty edition. Okay, it says fractions 102 00:08:24,519 --> 00:08:28,399 of an amp here calculations should be permitted to be rounded to the nearest whole 103 00:08:28,519 --> 00:08:35,039 number whole amp here, with decimal fractions smaller than point five to be dropped. 104 00:08:35,960 --> 00:08:41,639 That only applies to when you're doing ampacity, not when we're doing you 105 00:08:41,759 --> 00:08:46,960 know, kW right or something like that. We just want the answer, 106 00:08:46,240 --> 00:08:50,720 I just I just want the answer. Yeah, when you go to translate 107 00:08:50,799 --> 00:08:56,360 that into amps, then you can do your rounding up or dropping off. 108 00:08:56,840 --> 00:09:01,279 But you know this, this rule, the fraction of an amp only applies 109 00:09:01,360 --> 00:09:09,240 to amperage, not to kW. Okay, so I think people you know, 110 00:09:09,879 --> 00:09:13,799 do get confused with that, but just remember that's what two twenty dot 111 00:09:13,840 --> 00:09:18,519 five is there for now. Interesting thing with the I'm talking about my favorites 112 00:09:18,799 --> 00:09:22,399 here. Interesting enough, when you start into part two for brand circuit loads 113 00:09:24,399 --> 00:09:28,320 in the twenty twenty three edition, it now loads it up front and it 114 00:09:28,480 --> 00:09:33,000 kind of gives you some direction moving forward, like it says, okay, 115 00:09:33,080 --> 00:09:37,240 you've got two twenty dot ten, which is general, and then it's got 116 00:09:37,320 --> 00:09:41,000 a one, two, three, four five, and it's reminding you that 117 00:09:41,279 --> 00:09:46,720 two twenty dot fourteen is for other loads all occupancies. To twenty dot sixteen 118 00:09:46,879 --> 00:09:52,360 is for additions to existing installations. To twenty dot forty one is for dwelling 119 00:09:52,519 --> 00:09:58,519 units, to twenty dot forty two is for lighting loads for non dwelling occupancies, 120 00:09:58,919 --> 00:10:01,240 and then to twenty forty boards for hotels and motel occupancies. Right, 121 00:10:01,320 --> 00:10:05,399 so this is your general brand circuit loading requirements. So I like how it 122 00:10:05,679 --> 00:10:09,759 starts out that way, kind of sets the kind of sets the tongue. 123 00:10:11,759 --> 00:10:16,559 And then after that you've got two twenty dot eleven, which tells you this 124 00:10:16,759 --> 00:10:20,200 is the maximum loads. Right, so this is the load on a brand 125 00:10:20,279 --> 00:10:24,360 circuit, and it's shannocks see the rating of the brand circuit nor the maximum 126 00:10:24,440 --> 00:10:30,080 load that are specified. Right in two twenty dot eleven A through C under 127 00:10:30,279 --> 00:10:35,600 the conditions specified therein. So this is where you get the guidance things for 128 00:10:35,960 --> 00:10:39,440 motors, for example, motor operated and combined loads. This is where it's 129 00:10:39,440 --> 00:10:45,320 going to give you, for example, for the brand circuits for four thirty 130 00:10:45,360 --> 00:10:48,440 dot twenty two, for conductor sizing all of that dinner. If you have 131 00:10:48,600 --> 00:10:52,639 multiple motors, that's where it's going to give you some guidance for four thirty 132 00:10:52,879 --> 00:10:56,320 twenty four where you take one hundred and twenty five percent of the largest motor 133 00:10:58,440 --> 00:11:01,759 at NFLC and then the some of the other motors that are in the same 134 00:11:01,840 --> 00:11:07,519 group. This is where you start to get that permission, right because we're 135 00:11:07,759 --> 00:11:13,120 we're talking about prance circuits here. And then of course you get things like 136 00:11:13,279 --> 00:11:18,480 cooking equipment under sea that it again says that ranges one amount of ovens, 137 00:11:18,519 --> 00:11:22,519 countermount of cooking units and other household cooking appliances in excessive one in three quarter. 138 00:11:24,120 --> 00:11:28,759 They're permitted to use the values and table to twenty dot fifty five. 139 00:11:28,840 --> 00:11:35,000 So that's where you get the permission. So a lot of times people overlook 140 00:11:35,039 --> 00:11:37,440 that, they just go straight into two twenty fifty five and they wanted, 141 00:11:37,519 --> 00:11:41,919 okay, I get it that I'm doing this for ranges, but what actually 142 00:11:41,960 --> 00:11:45,240 gave me the permission to be here? And that's why you got to go 143 00:11:45,320 --> 00:11:48,840 back and say, well, now in a twenty twenty three edition two twenty 144 00:11:48,039 --> 00:11:52,720 to eleven does that okay? So that's kind of one of my favorite things. 145 00:11:52,759 --> 00:11:56,039 Now in two twenty fourteen, again, this is all occupancy, So 146 00:11:56,120 --> 00:12:00,519 this applies to all. This is not just dwellings. This is every occupancy. 147 00:12:01,000 --> 00:12:07,879 It has a systematic list of A through K okay, And people ask 148 00:12:07,960 --> 00:12:09,879 me all the time it's like, well, what happens if I have a 149 00:12:11,000 --> 00:12:15,679 load to a specific appliances and it's not really covered under here, under B, 150 00:12:15,960 --> 00:12:16,960 C, D, E, F, G, H J K. 151 00:12:18,440 --> 00:12:22,879 Well, A would come into play because A is talking about a specific appliance 152 00:12:22,960 --> 00:12:26,360 or load. So if it's not like I have some specific appliance and it 153 00:12:26,440 --> 00:12:31,879 doesn't fit nicely in these little lists here that I don't have to account for 154 00:12:31,960 --> 00:12:35,039 the load, you do have to account for the load. So where would 155 00:12:35,080 --> 00:12:39,879 that fall? Well, it falls under A. Right it says an outlet 156 00:12:39,000 --> 00:12:45,240 for a specific appliance or other load not covered into twenty fourteen B through K 157 00:12:45,480 --> 00:12:50,320 shabby calculated based on the ampere rating of the appliance or the load serf. 158 00:12:50,440 --> 00:12:54,480 So again, it's still got to account for it. So I do get 159 00:12:54,519 --> 00:12:58,679 that question a lot from people. A good example of that would be a 160 00:12:58,720 --> 00:13:03,639 lot of times you could have let's say you had a cooking appliance that was 161 00:13:03,799 --> 00:13:07,720 less or one in three quarter or less. Well, still got account for 162 00:13:07,799 --> 00:13:11,679 that load. You just don't apply it to any demands in two twenty out 163 00:13:11,720 --> 00:13:13,759 fifty five. But you still have to account for the load. The load 164 00:13:13,879 --> 00:13:20,480 is there, it's not going anywhere, right, But you again, you 165 00:13:20,600 --> 00:13:24,120 have all of these allowances in here, fluminaires, signage, show windows, 166 00:13:24,960 --> 00:13:31,919 multi outlet assemblies, receptable outlets. Again, other than what you do in 167 00:13:31,000 --> 00:13:37,000 residential okay, which is two twenty fourteen j Well, not jay, excuse 168 00:13:37,080 --> 00:13:39,720 me. Two twenty dot forty one's where it is now, Okay, two 169 00:13:39,720 --> 00:13:45,080 twenty out forty one is where you're gonna get all of the rules for one 170 00:13:45,159 --> 00:13:48,039 family, two family, multifami. They used to be two twenty dot fourteen. 171 00:13:48,120 --> 00:13:52,879 So let's see there's the change, right. So what that is saying 172 00:13:52,000 --> 00:13:56,679 is that any receptable outlet, okay, it's going to be rated in one 173 00:13:56,759 --> 00:14:01,559 hundred and eighty v A. Now that does not apply to sidential that is 174 00:14:01,720 --> 00:14:05,559 going to be engulfed, right, your general use receptacles around your living room, 175 00:14:05,720 --> 00:14:09,600 your bedroom, that's all engulfed in that three VA per square foot, 176 00:14:09,960 --> 00:14:13,360 and that's now going to be in two twenty forty one rather than two twenty 177 00:14:13,639 --> 00:14:18,000 fourteen JA where it was in the twenty twenty or prior. And that makes 178 00:14:18,080 --> 00:14:24,200 sense right to kind of break this down. So since we're talking just receptacle 179 00:14:24,200 --> 00:14:28,639 outlets other than dwelling units, then it's one hundred and eighty VA per outlet. 180 00:14:30,919 --> 00:14:37,240 Now what's interesting with that is that even if it's a simplex, duplex, 181 00:14:37,200 --> 00:14:43,240 triplex, if it's just one strap, then it's one hundred and eighty 182 00:14:43,320 --> 00:14:48,480 VA. That's it, right. If it's a two gang box and you 183 00:14:48,600 --> 00:14:52,320 put two duplexes in there, then it's one hundred and eighty each, right, 184 00:14:52,879 --> 00:14:58,559 makes sense. Okay, So anyway, it's it's all seems to just 185 00:15:00,120 --> 00:15:05,879 flow so much better. And so the whole point of this, you know, 186 00:15:05,200 --> 00:15:09,600 I was asking my opinion, and so as an educator, one of 187 00:15:09,639 --> 00:15:13,840 the things that people always say to me is, Paul, what can you 188 00:15:13,000 --> 00:15:18,679 do? What can they do to make calculation especially low costs. Probably one 189 00:15:18,720 --> 00:15:26,080 of the most complicated daily tasks that somebody might have is a low calc and 190 00:15:26,240 --> 00:15:28,559 anything that you can do in a code to make it easier for people to 191 00:15:28,679 --> 00:15:35,799 understand it easier to learn the process. Now, in our courses, our 192 00:15:35,840 --> 00:15:39,399 fast track programs, we give you a nifty little sheet that you can use, 193 00:15:39,519 --> 00:15:43,159 and that's just to kind of get used to doing it over and over 194 00:15:43,240 --> 00:15:48,240 over again in your head and it becomes second nature and you just end up 195 00:15:48,440 --> 00:15:52,840 just knowing it. You're building up that knowledge base, that repository of knowledge 196 00:15:52,879 --> 00:15:56,200 in your head. Right as I tell people all the time, you could 197 00:15:56,240 --> 00:15:58,799 feel that beaker up so much over time, you're gonna lose something, whether 198 00:15:58,840 --> 00:16:03,440 you have evaporative knowledge or you just forget something, because out of sight, 199 00:16:03,519 --> 00:16:07,120 out of mind, you're always trying to refill that beaker of knowledge. And 200 00:16:07,159 --> 00:16:10,879 if you can learn something from somebody else, you don't have to know more 201 00:16:10,960 --> 00:16:14,679 than somebody else. But if you shut up and listen to them. This 202 00:16:14,840 --> 00:16:17,759 is why I love to listen to other educators. And it's not whether I 203 00:16:17,840 --> 00:16:19,200 think they know more than me or less than me, it doesn't matter. 204 00:16:21,200 --> 00:16:25,360 It's that they might have one little nugget of knowledge that I can put in 205 00:16:25,480 --> 00:16:26,960 my repository to help me. And that's the way you got to look at 206 00:16:27,000 --> 00:16:32,480 it, right, that's the way you have to look at it. So 207 00:16:33,960 --> 00:16:38,080 I'm always trying to replenish my beaker, if you will, my beaker of 208 00:16:38,200 --> 00:16:42,720 knowledge. Okay, my reservoir of knowledge, because you're just going to forget 209 00:16:42,799 --> 00:16:47,519 things over time. It's just the way it is. But in doing so, 210 00:16:47,960 --> 00:16:51,720 they have made it so that it does to me. Just to me, 211 00:16:52,799 --> 00:16:57,840 it does flow better, right, just does flow better. Now, 212 00:16:57,879 --> 00:17:02,039 when you get to part three, which is is we refer to this and 213 00:17:02,159 --> 00:17:06,880 it doesn't say standard method, but we refer to this as the standard method. 214 00:17:06,960 --> 00:17:11,119 This is the the maybe it's the general method that you would use. 215 00:17:12,279 --> 00:17:17,200 We call it standard method versus optional. But you know, it's doesn't say 216 00:17:17,279 --> 00:17:21,359 standard. To my knowledge, it doesn't say standard. It's just the method. 217 00:17:21,480 --> 00:17:26,839 It's the method that we use on exams for those that are taking electrical 218 00:17:26,880 --> 00:17:30,960 exams. Even though in the real world we would probably never use the standard 219 00:17:30,079 --> 00:17:34,119 or this the general method. In part three, we would always use the 220 00:17:34,160 --> 00:17:38,480 optional. It's going to result in a smaller service ninety nine point nine percent 221 00:17:38,519 --> 00:17:41,720 of the time, and that's what we're after right. No sense putting in 222 00:17:41,720 --> 00:17:45,920 a six hundred amps service. If a feign a service will get away with 223 00:17:45,960 --> 00:17:48,200 it. No sense in trying to put a foreigner if a two hundred amps 224 00:17:48,240 --> 00:17:52,279 gonna work, fine, you know. So at the end of the day, 225 00:17:52,319 --> 00:17:56,319 if it was two hundred and eighty amps and standard method and you did 226 00:17:56,319 --> 00:17:59,519 it in the optional method and it was one ninety, then I'm going with 227 00:17:59,559 --> 00:18:02,559 the two MP code allows me to do it. You can say, well, 228 00:18:02,559 --> 00:18:03,759 I'd never do that. I'm going with the man. Well you do, 229 00:18:03,920 --> 00:18:07,319 you boo, what reality is. It's permitted in the code. I'm 230 00:18:07,359 --> 00:18:11,119 going to do it right, doesn't make it wrong. That's up to you. 231 00:18:11,799 --> 00:18:18,960 You have that choice under Part three. It reminds us, and again 232 00:18:18,079 --> 00:18:21,799 this is why I wanted to point this out. In two twenty dot forty 233 00:18:22,319 --> 00:18:26,519 of the twenty twenty three edition of the NBC, it says the calculated load 234 00:18:26,680 --> 00:18:32,400 of a feeder or service shall not be less than the sum of the loads 235 00:18:32,960 --> 00:18:38,839 on the brand circuits supplied as determined by Part two of this article after any 236 00:18:40,079 --> 00:18:45,440 applicable demand factors permitted or required by Part three, four or five sign blah 237 00:18:45,480 --> 00:18:48,119 blah are applied. So this tells you right off the bat that a lot 238 00:18:48,200 --> 00:18:52,200 of the information that you're going to use in part three for your service or 239 00:18:52,240 --> 00:18:56,839 feeder is coming from what you do in part two. So it makes sense 240 00:18:59,079 --> 00:19:04,680 you basically think of Part three is is collaborating and bringing everything together that you 241 00:19:06,079 --> 00:19:11,480 might have utilized under Part two, the pieces, if you will, pieces 242 00:19:11,519 --> 00:19:15,519 of the puzzle coming together under part three. So when you get to part 243 00:19:15,559 --> 00:19:19,960 three, then you get to two twenty forty one, which is basically new 244 00:19:22,039 --> 00:19:26,319 for the twenty The approach to it is new for the twenty twenty three. 245 00:19:26,440 --> 00:19:30,920 And this is again that's telling you know here. What's interesting is because a 246 00:19:30,000 --> 00:19:37,359 lot of people get confused about can the general use receptacles through does that three 247 00:19:37,480 --> 00:19:41,759 VA which was lighting? Everybody referred to that as the general lighting, and 248 00:19:41,839 --> 00:19:44,920 then you had to convince everybody that no, well you can also put the 249 00:19:45,000 --> 00:19:49,720 receptacles like in your living room and bedroom and basement. You can put that 250 00:19:49,880 --> 00:19:56,000 those that three VA is encompassed in that. People still wanted to debate. 251 00:19:56,279 --> 00:19:57,039 I wanted to argue, and they say, wall wait a minute, it 252 00:19:57,079 --> 00:20:03,400 says general lighting. And then you had to actually read it to to get 253 00:20:03,480 --> 00:20:06,920 clarity for it. So in this case. Now it says TO twenty forty 254 00:20:06,960 --> 00:20:12,039 one says dwelling units, and it says minimum unit load. Unit load means 255 00:20:12,200 --> 00:20:17,920 that unit's combined loading. And it starts out by saying one family, two 256 00:20:18,000 --> 00:20:22,319 family, and multi family dwellings, the minimum unit load shall be not less 257 00:20:22,680 --> 00:20:27,759 than three VA per square foot. So multi family buildings, you're doing the 258 00:20:27,920 --> 00:20:33,799 individual dwelling units at their unit load. Outside dimensions, you're you're coming up 259 00:20:33,839 --> 00:20:38,359 with your three VA square footage and you multiply that by three VA, and 260 00:20:38,519 --> 00:20:45,759 that's your starting point. That's your that's your your VA per square foot and 261 00:20:45,839 --> 00:20:49,799 it's three VA per square foot and you multiply that by whatever your square footage 262 00:20:49,839 --> 00:20:55,160 is, and that's your overall square footage. Okay. It also reminds you 263 00:20:55,680 --> 00:21:02,240 in very easy to understand terms. Now it says unit loads include the following 264 00:21:02,519 --> 00:21:12,160 lighting and receptacle outlets, and no additional load calculations shall be required. Now 265 00:21:12,240 --> 00:21:15,680 I kind of said that before, but you had to read between the lines. 266 00:21:15,839 --> 00:21:21,119 And people always complain that the NC is a difficult document to read, 267 00:21:21,480 --> 00:21:23,839 and they always go, why did you just say what you wanted to say? 268 00:21:26,160 --> 00:21:30,319 You have to remember that the folks that sit on code panels are very 269 00:21:30,400 --> 00:21:34,920 technical and they like to keep things technical. But there has been an effort 270 00:21:36,039 --> 00:21:40,319 to try to simplify, get rid of redundancy, remove certain terminologies, and 271 00:21:40,440 --> 00:21:42,759 try to make it a little easier to read. Still not losing the fact 272 00:21:42,839 --> 00:21:48,039 that this is not a document for the untrained it's this is very much a 273 00:21:48,119 --> 00:21:51,839 document for the trained person. So you gotta understand some terminologies. You got 274 00:21:51,920 --> 00:21:55,000 to You gotta kind of be in the in the program, right, you 275 00:21:55,079 --> 00:21:57,000 gotta understand what we're talking about to kind of get the gist of this document. 276 00:21:57,160 --> 00:22:00,319 You know, you're gonna crack it open and you're not familiar with the 277 00:22:00,079 --> 00:22:03,519 language, the trade slang or whatever, you're gonna you're gonna struggle. You 278 00:22:03,640 --> 00:22:11,839 are going to struggle. But this makes it very clear, right what's covered 279 00:22:12,000 --> 00:22:14,960 now? I get this question all the time. In fact, on one 280 00:22:15,000 --> 00:22:17,880 of our fast Tracks questions that are in our program. If you if you're 281 00:22:17,920 --> 00:22:21,279 not familiar with our fast Tracks program, go to our website fast tracks system 282 00:22:21,319 --> 00:22:23,559 dot com and watch the demo. Just go to the fast Tracks Black or 283 00:22:23,599 --> 00:22:27,319 the Plus and we've got a demo on there. One of the questions that 284 00:22:27,359 --> 00:22:33,640 people ask is if I have a rancher. Let's say there's a ranch dwelling 285 00:22:33,160 --> 00:22:41,279 and it's being placed on an unfinished basement and they don't finish the basement out, 286 00:22:41,960 --> 00:22:47,160 but they finished the first level, and they do a low calculation, 287 00:22:47,240 --> 00:22:48,599 a size the service, and all this kind of good stuff, and then 288 00:22:48,640 --> 00:22:52,680 it come back and aside they want to finish off the basement. Do I 289 00:22:52,839 --> 00:22:56,920 have to change that service? Do I have to do a calculation if all 290 00:22:56,960 --> 00:23:00,880 I'm doing is putting lighting and receptacles in there, just just normal general use 291 00:23:00,920 --> 00:23:07,599 stuff. Well, when they did their calculation, they needed to calculate in 292 00:23:07,880 --> 00:23:15,160 that square footage at three VA per square foot because it was clearly adaptable for 293 00:23:15,279 --> 00:23:19,559 future use. Somebody was going to finish that off someday. It's irrelevant whether 294 00:23:19,599 --> 00:23:26,680 it's finished off now. It was adaptable for future use, so you would 295 00:23:26,680 --> 00:23:33,400 be counting the square footage from the basement as well as the first floor when 296 00:23:33,480 --> 00:23:37,640 you did your original low calculation. So if I come back, electricians come, 297 00:23:37,720 --> 00:23:41,599 I'm coming in later and I'm going to be finishing off that basement, 298 00:23:41,559 --> 00:23:47,799 I don't have to add any additional load to that service. It is that 299 00:23:48,039 --> 00:23:52,839 three VA per square foot that was figured in is adequate, perfectly fine. 300 00:23:52,640 --> 00:23:59,160 Okay. So I think a lot of times when electricians do low calculations, 301 00:23:59,200 --> 00:24:02,359 even today, you know, very few do anymore. They just look at 302 00:24:02,400 --> 00:24:03,119 a house and go, oh, that looks like a two hundred AM. 303 00:24:03,200 --> 00:24:07,279 Ask yourself this and be honest when you bid your last house, did you 304 00:24:07,480 --> 00:24:11,400 actually do a low couch or did you just go and it looks like, 305 00:24:11,480 --> 00:24:15,559 that's two hundred AMP. I've done this before, and that might nay or 306 00:24:15,599 --> 00:24:19,279 may not be fine. Standard spec houses, standard stick house, that's probably 307 00:24:19,359 --> 00:24:25,400 fine. Houses I used to do were eight thousand, ten thousand square foot 308 00:24:25,440 --> 00:24:29,319 houses. I had to do a load calculation because I did not want to 309 00:24:29,359 --> 00:24:32,720 put a service that was unnecessary. I did not want to put an eight 310 00:24:32,799 --> 00:24:36,200 hundred AMP if a four hundred AMP could be fine. Bigger equipment, bigger 311 00:24:36,279 --> 00:24:41,240 headache, more rules from the utility that I had to jump through the hoops 312 00:24:41,240 --> 00:24:45,759 when you went to an eight hundred. I really focused on my low calcs. 313 00:24:47,839 --> 00:24:51,240 I get it. HiT's a little fifteen hundred square foot twenty twenty five 314 00:24:51,319 --> 00:24:52,680 hundred square foot house. Even up to a three thousand square foot house, 315 00:24:52,720 --> 00:24:56,279 probably two hundred AP is going to be more than enough due to diversity. 316 00:24:56,359 --> 00:24:59,519 It's probably fine. Now I do question at the day with all the other 317 00:24:59,559 --> 00:25:03,200 stuff EV and all this other stuff that's being added, it may be who 318 00:25:03,359 --> 00:25:07,400 view to do a low calculation, but every electrician said, at least know 319 00:25:07,440 --> 00:25:10,960 how to do it right. You should know how to do it. But 320 00:25:11,160 --> 00:25:14,200 when it comes to that basement, now they shouldn't have to do anything. 321 00:25:14,519 --> 00:25:17,400 That three vapor square foot should alad be figured in the size of the service. 322 00:25:17,680 --> 00:25:22,119 So nothing additional, and it makes it very clear here. Now it 323 00:25:22,240 --> 00:25:27,720 also add additional language to make it very clear in this when you're doing this 324 00:25:27,880 --> 00:25:33,759 unit load minimum unit load. It says the minimum lighting load shall be determined 325 00:25:33,880 --> 00:25:41,599 using the multiple unit load and the floor area as determined into twenty five C. 326 00:25:41,920 --> 00:25:45,880 So that's a reference back to how to calculate the outside dimensions to do 327 00:25:47,039 --> 00:25:48,720 that for the dwelling unit. Okay, And then it says, you know 328 00:25:48,839 --> 00:25:53,720 what, you're gonna have some motors, probably so motors that are rated less 329 00:25:53,720 --> 00:25:56,759 than an eighth horse power, so they had to be less than an eighth 330 00:25:56,839 --> 00:26:00,519 horse power. It's not one eighth horsepower or less. It says motors rated 331 00:26:00,920 --> 00:26:07,359 less than eight horse power and connected to a lighting circuit should be considered part 332 00:26:07,440 --> 00:26:11,920 of the minimum lighting load, so it's already encompassed in that three vapor square 333 00:26:11,920 --> 00:26:17,920 foot. So typical ceiling fans where people wanted to argue that those motors weren't 334 00:26:17,920 --> 00:26:21,480 accounted for a look, most of the ceiling fan motors are going to be 335 00:26:21,640 --> 00:26:23,960 less than an eighth horse power. Then at the end of the day, 336 00:26:25,839 --> 00:26:30,480 it's just it's just part of the three va per square foot. Don't have 337 00:26:30,599 --> 00:26:34,880 to rack your brain, cause any brain mustard to go on. It's just 338 00:26:36,119 --> 00:26:41,440 done. It's already considered. Okay. Now, one of the significant changes 339 00:26:42,680 --> 00:26:48,000 in relocation now for to twenty that I kind of like, is that now 340 00:26:48,279 --> 00:26:52,960 instead of it being two twenty dot twelve for the other than dwelling applications or 341 00:26:53,039 --> 00:26:57,119 non dwelling occupancies where you need to get the vapor square foot, you know, 342 00:26:57,319 --> 00:27:03,200 like for you know, dormitory, court houses, uh, you know, 343 00:27:03,519 --> 00:27:07,440 convention centers, healthcare of clinics and on. That used to be two 344 00:27:07,480 --> 00:27:11,960 twenty dot twelve. And I didn't like that because that was up kind of 345 00:27:11,039 --> 00:27:15,519 in the branch circuit thing. It was kind of moved up and it just 346 00:27:15,720 --> 00:27:21,559 really didn't make sense. So it is now into twenty dot forty two, 347 00:27:22,400 --> 00:27:27,160 and it's still similar table as you're all familiar with. It's going to give 348 00:27:27,200 --> 00:27:33,000 you the VA per square foot, and you know it's had some the notes 349 00:27:33,079 --> 00:27:38,240 underneath it and been kind of expanded for clarity. That's great, but that's 350 00:27:38,240 --> 00:27:44,480 where you're gonna get your vapor square foot when you're doing your calculation for like 351 00:27:44,680 --> 00:27:49,400 office buildings and and things like that. Okay, retails, restaurants, religious 352 00:27:49,440 --> 00:27:52,480 facilities, post offices, that's where you're gonna get that. So that's when 353 00:27:52,519 --> 00:27:56,680 you start your like But the key thing to remember here, folks, is 354 00:27:56,759 --> 00:28:00,039 that's lighting alone, and that's where a lot of people get confused. So 355 00:28:00,160 --> 00:28:03,000 with dwellings, you're able to combine in general use receptacles I remember, and 356 00:28:03,079 --> 00:28:07,400 not talking small appliance, laundry things like that. That's got its own rules, 357 00:28:07,319 --> 00:28:12,559 that's got its own requirements. And to have fifteen hundred VA per small 358 00:28:12,599 --> 00:28:18,000 appliance per laundry and the minimums that are required with that. We get that 359 00:28:18,440 --> 00:28:22,400 to ten dot eleven. See all that type of rules, and in two 360 00:28:22,519 --> 00:28:27,519 ten fifty two we get it. It's not but what I'm talking about here, 361 00:28:29,319 --> 00:28:33,960 this is only the lighting load and the easiest way to remember it is 362 00:28:33,000 --> 00:28:37,079 if it's not a dwelling, you're going to treat the lighting and the receptacles 363 00:28:37,160 --> 00:28:41,880 separate. And it was always like that, but because of where it was 364 00:28:42,000 --> 00:28:48,559 located, it just seemed to me. Other educators can disagree, and that's 365 00:28:48,599 --> 00:28:52,319 fine. Everybody's entitled to their opinion, and I welcome other opinions. But 366 00:28:52,559 --> 00:28:56,759 for me who primarily what sets me apart from a lot of other educators, 367 00:28:56,799 --> 00:29:00,480 And this is not a pad on the back, folks, what I'm doing. 368 00:29:00,839 --> 00:29:07,200 What I'm saying is I spend a lot of time in exam prep. 369 00:29:08,119 --> 00:29:12,000 I'm known for my exam prep. Although I teach code to give analysis of 370 00:29:12,079 --> 00:29:15,799 code, I answer code quick, I consult. In fact, I'm heading 371 00:29:15,839 --> 00:29:18,759 next month up to New York for a case that I'm going to be expert 372 00:29:18,839 --> 00:29:22,440 witness on. I spend a lot of time in the code. But I 373 00:29:22,519 --> 00:29:26,200 am also known heavily for my exam prep. So when I tell you that 374 00:29:26,279 --> 00:29:33,000 I think that this flows better, it flows better from a perspective of being 375 00:29:33,079 --> 00:29:37,039 able to have students follow it a little bit better, and when they get 376 00:29:37,079 --> 00:29:42,240 out into the field and they encounter an issue, they're much more adapted. 377 00:29:42,319 --> 00:29:45,640 To being able to solve this issue because they understand how these things work. 378 00:29:48,160 --> 00:29:51,519 So that's what I mean by that, And I just mean that I spend 379 00:29:51,559 --> 00:29:56,240 a lot of time in exam prep. So when I say something flows better, 380 00:29:56,720 --> 00:30:02,599 it's just my opinion. But I think students can't agree that it flows 381 00:30:02,680 --> 00:30:04,960 better, right, or at least makes more sense if you will. So 382 00:30:06,200 --> 00:30:10,279 having this removed from two twenty dot twelve and put in two twenty forty two 383 00:30:10,319 --> 00:30:15,000 just just makes so much more sense. Okay, all right, So again 384 00:30:15,039 --> 00:30:17,839 that's going to give you a vapor square foot and whatnot, and of course 385 00:30:17,880 --> 00:30:19,680 you've got your energy code allowance, but I think most people ignore that. 386 00:30:21,119 --> 00:30:25,160 That means that you can ignore the vapor square foot for the lighting and use 387 00:30:25,240 --> 00:30:27,759 the energy code if you follow all of these points, these all these conditions 388 00:30:27,799 --> 00:30:33,160 are met. That might be great. If you've got an injury management system 389 00:30:33,440 --> 00:30:37,279 and an engineer's working this all out, and it may be that the overall 390 00:30:38,519 --> 00:30:44,799 VA for the lighting is less due to the energy code, then it would 391 00:30:44,839 --> 00:30:49,240 be based on using TO twenty forty two. Then you know what, that 392 00:30:49,400 --> 00:30:53,720 engineer has to sign off on that and they're responsible for that and most of 393 00:30:53,720 --> 00:31:00,559 the engineers I know aren't going to do that. I maybe a multi million 394 00:31:00,640 --> 00:31:04,559 dollar system with the so much intricral stuff that controls everything, they might I 395 00:31:04,640 --> 00:31:08,000 mean, that's not going to be what extra money. But the normal projects, 396 00:31:08,039 --> 00:31:11,680 the engineers are gonna say, now I'm just going to go the VAPRI 397 00:31:11,720 --> 00:31:15,240 and I'm just gonna follow the normal and I'm gonna do two twenty forty two 398 00:31:15,279 --> 00:31:17,680 and be done with it. But you do have an energy code provision. 399 00:31:18,319 --> 00:31:22,440 And now with everybody so focused on the energy code even more, I guess 400 00:31:22,559 --> 00:31:25,799 that this one was there before. It was there in the twenty twenty. 401 00:31:25,920 --> 00:31:30,960 I mean, this is not new, but you know I've probably not geared 402 00:31:32,000 --> 00:31:37,000 towards following it. And now you also get into things like the office buildings. 403 00:31:37,039 --> 00:31:41,440 These are going to be for the receptacles. It's only applies to office 404 00:31:41,480 --> 00:31:44,279 buildings. You have two twenty out forty three. So again remember any other 405 00:31:44,319 --> 00:31:47,759 building, it's one hundred and eighty VA per strap. But here you have 406 00:31:47,880 --> 00:31:51,759 some office buildings and it's going to give you a choice of using the one 407 00:31:51,799 --> 00:31:55,759 hundred and eighty v A per strap or one VA per square foot whichever, 408 00:31:56,119 --> 00:31:59,279 okay is the larger. That's what you're going to use, and then of 409 00:31:59,359 --> 00:32:01,680 course you have to twenty forty four hotels and mode TESTE. How it's logically 410 00:32:01,759 --> 00:32:08,119 flowing a little bit better now when it comes to the general lighting and allowances. 411 00:32:09,359 --> 00:32:14,880 Right, remember that table that used to be too twenty do I think 412 00:32:14,920 --> 00:32:17,200 it was? To twenty dot forty two, which is the for dwelling units, 413 00:32:17,279 --> 00:32:20,559 right, the first three thousand, one hundred percent, the next one 414 00:32:20,640 --> 00:32:22,799 hundred and seventeen thousand and thirty five percent. Anything over one hundred and twenty 415 00:32:22,880 --> 00:32:27,920 is at twenty five percent. Well, that's now to twenty dot forty five, 416 00:32:29,079 --> 00:32:31,759 same table, same there, it's just been moved. These are the 417 00:32:31,839 --> 00:32:37,279 demand factors that you get to apply to the lighting loads. Let's saying the 418 00:32:37,359 --> 00:32:40,559 dwelling, to the small appliance, to the laundry, all of that that 419 00:32:40,680 --> 00:32:45,640 you compile. This is where you get to apply those things. And what 420 00:32:45,799 --> 00:32:53,359 twenty forty five says is the demand factor specified in table two twenty dot forty 421 00:32:53,440 --> 00:33:00,160 five shall apply to that portion of the total brand circuit load calculating for general 422 00:33:00,240 --> 00:33:06,640 illumination. They shall not be applied in determining the number of brand circuits for 423 00:33:06,799 --> 00:33:09,279 the general lighting. So you're lighting. You're gonna you're gonna know the number 424 00:33:09,279 --> 00:33:13,559 of brand circuit based on the loads you have, and you're gonna be the 425 00:33:13,680 --> 00:33:16,279 number of brand circuits to depending on how many luminaires you had, And that's 426 00:33:16,279 --> 00:33:21,359 all based on the loads whatever the luminaires are. You don't use this to 427 00:33:21,480 --> 00:33:23,440 do that. Okay. So if I have a building and I have all 428 00:33:23,480 --> 00:33:28,440 these lighting circuits, they're gonna have a certain amount of load to them, 429 00:33:28,519 --> 00:33:30,680 and I got to size the brands, so I could have a need for 430 00:33:30,799 --> 00:33:34,599 twenty brand circuits, where if I use this, it might show that only 431 00:33:34,680 --> 00:33:38,000 needed eight. But you don't use this for that, Okay. You have 432 00:33:38,119 --> 00:33:42,200 to use the brand circuits. You have to know that you're gonna be adequately 433 00:33:42,200 --> 00:33:45,519 supplying those loads. This is just for the demand of the service, So 434 00:33:45,680 --> 00:33:51,440 that's what reminds you. You don't use this for determining how many brand circuits 435 00:33:51,480 --> 00:33:54,640 you need to supply that general lighting. This is just because it's under Part 436 00:33:54,680 --> 00:34:00,640 three. This is just for the service or feeder application. Okay. Now, 437 00:34:01,319 --> 00:34:07,240 one of the things that I often tell people in here is that twenty 438 00:34:07,839 --> 00:34:12,280 five if we're doing the dwelling, and you remember what it allowed me to 439 00:34:12,360 --> 00:34:15,280 do. It allowed me to pick up the lighting as well as it allowed 440 00:34:15,320 --> 00:34:21,599 me to pick up those general use receptacle applications, and it allowed me to 441 00:34:22,559 --> 00:34:28,000 pick up other things in there like the laundry and the small clients. And 442 00:34:28,039 --> 00:34:30,519 when I when I'm applying this, I am able to apply this to that 443 00:34:30,840 --> 00:34:37,119 all of that, okay, So that is one aspect of that people will 444 00:34:37,199 --> 00:34:42,880 lose out one that I'm permitted to apply that all right. Now, I 445 00:34:43,000 --> 00:34:47,880 guess when when people see that or they get confused with that and they start 446 00:34:47,920 --> 00:34:52,000 to say, well, I get get confused, and how I'm able to 447 00:34:52,079 --> 00:34:58,920 apply all that? You have to understand that that's all part of the unit 448 00:34:59,079 --> 00:35:04,679 load at least when we're talking about dwelling units for example. And that's what 449 00:35:04,800 --> 00:35:09,159 allows me to apply that under to twenty forty five because it says type of 450 00:35:09,239 --> 00:35:20,320 ocupancy dwelling unit. Right, let's see here again goes into show windows, 451 00:35:20,360 --> 00:35:25,119 track lighting, and then of course it has receptacles again other than dwelling units. 452 00:35:25,159 --> 00:35:30,840 So remember the rules for whether it's multi multi outlet assemblies or it's at 453 00:35:30,840 --> 00:35:35,320 one hundred and eighty VA per square foot. If you're not dealing with the 454 00:35:35,519 --> 00:35:39,760 office rule that we talked about. Then you have other than dwellings, so 455 00:35:40,000 --> 00:35:45,000 now you get to apply an additional demand factor to non dwelling receptacle loads, 456 00:35:45,079 --> 00:35:50,519 and that's where you would use to twenty forty seven for that application, right, 457 00:35:52,440 --> 00:35:54,840 And then of course then you got to twenty to fifty, which is 458 00:35:54,880 --> 00:35:59,800 the motors that I don't think they added much clarity to that, but it's 459 00:36:00,039 --> 00:36:05,199 still reminds you that motors and air conditionings basically, long story short, you 460 00:36:05,320 --> 00:36:07,239 take the motor at one hundred twenty five percent, and when you're doing the 461 00:36:07,280 --> 00:36:13,239 low calculation, you just take the largest motor at one hundred twenty five percent 462 00:36:13,239 --> 00:36:15,239 if you have multiple motors, and then you have the sum of all the 463 00:36:15,280 --> 00:36:19,800 other motors. So that's where we tell you in a calculation, find the 464 00:36:19,920 --> 00:36:23,320 largest motor and try to capture that additional twenty five percent because it's probably already 465 00:36:23,320 --> 00:36:27,639 been captured at one hundred percent, So all you're trying to do is get 466 00:36:27,719 --> 00:36:30,880 that additional twenty five percent in order to comply with two twenty fifties rules. 467 00:36:31,320 --> 00:36:34,679 And that's the same thing for air conditioning, where it tells you to take 468 00:36:34,719 --> 00:36:37,559 it at one hundred and twenty five percent. Well, that's just kind of 469 00:36:37,719 --> 00:36:43,360 and I usually tell students that's the twenty five percent rule. Okay, but 470 00:36:43,559 --> 00:36:49,239 remember this one in two twenty fifty doesn't just apply to dwellings. This is 471 00:36:49,360 --> 00:36:52,320 broad. It applies to all motor applications, and it's not just a dwelling 472 00:36:52,440 --> 00:36:54,760 unit. But it seems to me when I'm explaining it to people, it 473 00:36:54,880 --> 00:37:00,320 seems to always be easier to do it in a dwelling application. Right in 474 00:37:00,360 --> 00:37:04,039 two twenty dot fifty one space heating, baseboard heating, all that kind of 475 00:37:04,079 --> 00:37:08,400 stuff that you're heating. And then of course two twenty out fifty two that 476 00:37:08,599 --> 00:37:13,920 is your And I think I said two ten to fifty two earlier for the 477 00:37:14,119 --> 00:37:15,000 for this, but no, it's two twenty out fifty two. This is 478 00:37:15,000 --> 00:37:19,079 where you get the fifteen hundred VA for the minimum of two small appliants. 479 00:37:19,119 --> 00:37:21,400 You could have more than one, I mean more than two, but you 480 00:37:21,480 --> 00:37:23,599 have to have at least two. And that's the laundry where you take it 481 00:37:23,639 --> 00:37:28,159 at fifteen hundred as well. If you have three laundries circuits, then you 482 00:37:28,280 --> 00:37:30,039 take each one at fifteen hundred. If you have six small appliance circuits, 483 00:37:30,079 --> 00:37:35,000 you take each one in fifteen hundred, okay, and then of course you 484 00:37:35,079 --> 00:37:37,679 get into your appliances. So I'm not going to go into everything here. 485 00:37:37,760 --> 00:37:43,360 I'm going to cut this one off. But you can see that the flow 486 00:37:43,519 --> 00:37:46,840 is much better, right to me, the beginning, the load end of 487 00:37:46,880 --> 00:37:51,440 the flow is much better. Also for twenty twenty three, we added people 488 00:37:51,559 --> 00:37:59,119 ask how do you incorporate ev SE Okay, so electric vehicles supply equipment, 489 00:37:59,199 --> 00:38:01,119 how do you figure that add into your service or feed or load calculation? 490 00:38:01,239 --> 00:38:05,480 Will Now you have two twenty to fifty seven that's going to do that, 491 00:38:06,360 --> 00:38:09,719 and it's basically telling you that the ev SC load shall be calculated at either 492 00:38:09,920 --> 00:38:15,199 seventy two hundred watts, which to me or equivalent to VA. That is 493 00:38:15,280 --> 00:38:20,320 your base value. Unless you know the equipment that's being installed is a higher 494 00:38:20,440 --> 00:38:25,400 nameplate value, then you take whichever is larger. Now, if the engineer 495 00:38:25,559 --> 00:38:30,679 or whoever's designing it is putting in an ev system and they just a note 496 00:38:30,760 --> 00:38:36,199 that you're doing that, then you base that on seventy two dats. Okay. 497 00:38:37,760 --> 00:38:43,559 Now, if they know the equipment right that's going to be installed, 498 00:38:44,840 --> 00:38:47,559 then that's that's another thing. For example, if it's a fifty amp unit, 499 00:38:47,760 --> 00:38:52,320 it's a level two charging system, then it's probably going to be greater 500 00:38:52,440 --> 00:38:57,800 than seventy two hundred watts, okay, because typically seventy two hundred watts is 501 00:38:57,840 --> 00:39:01,599 going to equate to about thirty AM. But if they know the equipment, 502 00:39:02,400 --> 00:39:07,400 it's a minimum of seventy two hundred or the rating of the equipment, whichever 503 00:39:07,519 --> 00:39:10,199 is greater. There's there, I'm gonna tell you this much. If they 504 00:39:10,280 --> 00:39:15,400 don't know, but you know you're gonna have an EVS in the system, 505 00:39:15,480 --> 00:39:17,639 like maybe you're in California where that's you know they're starting to want to mandate 506 00:39:17,679 --> 00:39:23,159 stuff like that. Then go on and add the seventy two hundred into your 507 00:39:23,199 --> 00:39:29,199 calculation. You don't have to speculate, well, what if they come in 508 00:39:29,280 --> 00:39:32,599 and put a bigger one. This is the service calculation. So luckily there's 509 00:39:32,719 --> 00:39:37,440 enough to diversity. It'd be nice to know what you're installing, but at 510 00:39:37,480 --> 00:39:39,239 a minimum, if you know there's an EVSC going to be installed, at 511 00:39:39,360 --> 00:39:43,920 least a minimum of seventy two hundred. If there is no nameplate or you 512 00:39:43,960 --> 00:39:49,840 don't know the equipment, okay, the good news is there's going to be 513 00:39:50,039 --> 00:39:54,800 enough diversity now when it's also going to dictate what circuit is being run to 514 00:39:54,920 --> 00:39:59,559 it. Obviously, if they're running a six gauge or something like that, 515 00:40:00,280 --> 00:40:02,800 then it's probably going to be a piece of equipment that's going to be greater 516 00:40:02,920 --> 00:40:07,119 than seventy two hundred watts, So you're gonna have to do your due diligence 517 00:40:07,159 --> 00:40:09,559 and check it out. I'm just telling you the CODES is a minimum. 518 00:40:09,639 --> 00:40:14,079 Now, if you're going to have an EVS in your building, this is 519 00:40:14,119 --> 00:40:16,719 not requiring one, by the way, it's if you do have it, 520 00:40:17,559 --> 00:40:23,719 okay, then it's seventy two hundred lots minimum, okay, or the nameplate, 521 00:40:23,880 --> 00:40:30,159 whichever is greater. And then of course you have two twenty dot sixty, 522 00:40:30,280 --> 00:40:32,400 which is you know, kind of drove people crazy for years. This 523 00:40:32,559 --> 00:40:36,320 is a non coincident load. This is dealing with two loads that are not 524 00:40:36,400 --> 00:40:40,559 going to be operated simultaneously. This does not just deal with like AC versus 525 00:40:40,840 --> 00:40:45,000 heat. That's just an example we use as an educator, but this could 526 00:40:45,039 --> 00:40:47,679 be in a commercial, this could be an industrial. If you have two 527 00:40:47,719 --> 00:40:52,760 pieces of equipment that are not designed to run at the same time, then 528 00:40:52,039 --> 00:40:55,920 you use the one that's larger than the other. One, and so if 529 00:40:55,960 --> 00:41:00,519 you size it to the large one, then if the small one runs, 530 00:41:00,559 --> 00:41:04,599 who cares. So that's what we mean by non question. You don't have 531 00:41:04,679 --> 00:41:08,280 to take both of them into consideration when adding the loads, because the smaller 532 00:41:09,239 --> 00:41:12,599 is not going to be the larger. It is not going to be on 533 00:41:12,679 --> 00:41:15,280 at the same time as the smaller or the lesser, so it's perfectly fine. 534 00:41:15,320 --> 00:41:21,599 So that's what we mean by non coincident load. Okay, Now there 535 00:41:21,719 --> 00:41:23,960 was a change in twenty twenty that most people are aware of. When you're 536 00:41:24,000 --> 00:41:30,679 comparing these non coincident loads, right, is, if you're comparing two loads 537 00:41:30,440 --> 00:41:36,239 and they are non coincident, you take the one that's the larger if the 538 00:41:36,320 --> 00:41:43,679 one is the lesser. Okay, it happens to have is well, if 539 00:41:43,719 --> 00:41:46,400 you read a code, it says if the motor or air conditioning load is 540 00:41:46,480 --> 00:41:50,920 part of the non coincident loaded is not the largest, so it's the lesser, 541 00:41:51,840 --> 00:41:55,519 then you take it at one hundred and twenty five percent of either the 542 00:41:55,559 --> 00:41:59,800 motor load or the air conditional load, whichever one you're dealing with, whichever 543 00:42:00,119 --> 00:42:04,920 larger, and you use that in the calculation to compare which one that you 544 00:42:05,119 --> 00:42:10,280 use so when we're doing a dwelling, we use this as an example where 545 00:42:10,320 --> 00:42:15,400 you have the heat versus AC. Right, and and let's say that the 546 00:42:15,480 --> 00:42:22,480 heating and a system, the heating and air conditioning is is thermostatically interlocked so 547 00:42:22,719 --> 00:42:25,960 that the heat can't be on when the AC is on. Let's just use 548 00:42:27,039 --> 00:42:30,440 that as an example because that's easy for people to understand. If I do 549 00:42:30,599 --> 00:42:35,360 my calculation, my load for my heating is greater than the air conditioning load. 550 00:42:35,800 --> 00:42:37,639 Remembering that I'm going to include the air handler. If that's used to 551 00:42:37,639 --> 00:42:42,440 blow the heat around, I'm going to use that in both of my calculations. 552 00:42:43,000 --> 00:42:46,800 If the heat is greater than the AC, but the largest motor in 553 00:42:46,880 --> 00:42:51,519 the building, which is probably in a dwelling, it's can probably be your 554 00:42:51,519 --> 00:42:57,599 air conditioning unit, the air conditioning compressor. If that's the largest motor, 555 00:42:58,159 --> 00:43:00,719 then this is telling me to compare the two by taking that motor at one 556 00:43:00,800 --> 00:43:05,840 hundred and twenty five percent plus the some of the other loads like an air 557 00:43:05,920 --> 00:43:09,599 handler and condenser and a condensing fan, and now compare that to the heat. 558 00:43:09,639 --> 00:43:14,159 Again. If the heat is still greater than you just go with the 559 00:43:14,239 --> 00:43:17,559 heat, and now the AC is discounted. It's gone, But you still 560 00:43:17,639 --> 00:43:22,400 have to go find that second largest motor because you still gotta you still gotta 561 00:43:22,440 --> 00:43:24,320 meet to twenty fifty, right, and that probably gonna be something like a 562 00:43:24,360 --> 00:43:29,800 garbage disposer or whatnot. Okay, and you got you gotta get that extra 563 00:43:29,880 --> 00:43:32,480 twenty five percent. Okay, we talked about that earlier. But the heat's 564 00:43:32,480 --> 00:43:35,880 the one that's gonna win. And that's the one you're gonna size because it's 565 00:43:36,000 --> 00:43:39,480 greater than it. So it's okay because it's much greater that when the AC 566 00:43:39,719 --> 00:43:43,280 is running, it's not greater than the heat, so there's no harm. 567 00:43:43,360 --> 00:43:49,280 You're sizing everything for the greater or the loads. Makes sense. But let's 568 00:43:49,320 --> 00:43:53,480 say that that air conditioning compressor at one hundred and twenty five plus the air 569 00:43:53,599 --> 00:43:58,199 handler and a condensing fan ended up being greater than the heat all of a 570 00:43:58,239 --> 00:44:00,639 sudden, now it overtakes the heat. Well, now you're getting rid of 571 00:44:00,679 --> 00:44:05,920 the heat and you're using the air conditioning values. Well, now, since 572 00:44:05,960 --> 00:44:08,239 I took that air conditioning at one twenty five and that was the largest motor, 573 00:44:08,840 --> 00:44:12,320 now I don't have to do two twenty dot fifty. I don't have 574 00:44:12,400 --> 00:44:15,760 to go looking for the largest motor at one hundred twenty five percent, because 575 00:44:15,760 --> 00:44:20,079 I already did that in my calculation for the non coincident load, I'd use 576 00:44:20,119 --> 00:44:22,079 the air conditioning at one twenty five. See I didn't. I had to 577 00:44:22,239 --> 00:44:28,840 use it in order to follow the rules of two twenty sixty. But if 578 00:44:28,880 --> 00:44:32,280 the heat had been greater and I'd discounted the air conditioning altogether, then I 579 00:44:32,440 --> 00:44:36,800 still have to go hunting for the largest motor and I can't use the air 580 00:44:36,840 --> 00:44:40,199 conditioner because that's already been discounted. It's removed because we went with the heat. 581 00:44:42,199 --> 00:44:45,840 Hopefully that makes sense, okay. And when I see people do low 582 00:44:45,920 --> 00:44:52,639 calculations in our program and their numbers don't really come up to the end when 583 00:44:52,679 --> 00:44:54,519 we asked them to do a low cock and hey, I'm telling you, 584 00:44:54,639 --> 00:45:01,079 our course is not easy. Ask any of our students, and it's not 585 00:45:01,280 --> 00:45:06,199 easy. We ask you to calculate the loads on the dwelling. We give 586 00:45:06,280 --> 00:45:08,159 you all the variables, and we ask you to do it. Unit eight, 587 00:45:08,320 --> 00:45:12,920 eleven and thirteen are literally the hardest units in our program, and people 588 00:45:13,159 --> 00:45:17,280 struggle. But that's a good thing. It's good to struggle. It means 589 00:45:17,320 --> 00:45:21,840 that you're gonna remember it. If you're in the program, a structured program 590 00:45:21,920 --> 00:45:23,320 like mine, and you're just trying to bullet through it and get done like 591 00:45:23,400 --> 00:45:29,280 it's a freaking sprint, then you wasted your money. I'm the first one 592 00:45:29,320 --> 00:45:31,679 to tell you, I'm not gonna give your money back. Okay, I'm 593 00:45:31,719 --> 00:45:35,840 not giving you your money back. You made the stupid choice to try to 594 00:45:35,920 --> 00:45:39,880 race through it, but you have to remember it's there for a reason and 595 00:45:39,960 --> 00:45:43,920 it's complicated. Don't ask to throw in the towel. Don't say, Paul, 596 00:45:44,000 --> 00:45:46,239 give me the answers. Keep doing the units until you get it, 597 00:45:47,119 --> 00:45:50,920 and once you get over seventy percent, I'm going to give you the answers. 598 00:45:51,719 --> 00:45:54,719 And if you still don't get it, come to our Wednesday night sessions 599 00:45:55,039 --> 00:46:00,360 seven thirty every Wednesday night and ask say, hey, Paul, can you 600 00:46:00,480 --> 00:46:07,880 go over unit six question review number eight and I'll go review it for you. 601 00:46:08,280 --> 00:46:12,039 Okay, that's the importance of coming to it now. If you have 602 00:46:12,360 --> 00:46:14,840 if you have a question that's just out of the ballpark, then you need 603 00:46:14,880 --> 00:46:16,599 to give us twenty four hours in advance so we can put together a presentation 604 00:46:16,960 --> 00:46:21,480 so they don't kind of get people confused trying to wing it. But if 605 00:46:21,519 --> 00:46:24,280 it's part of the program, then you can come to the live event and 606 00:46:24,679 --> 00:46:28,840 you can ask Paul, can you explain this question in this unit. That's 607 00:46:28,880 --> 00:46:31,639 what it's for. So I think people got confused with the Wednesday nights about 608 00:46:31,719 --> 00:46:35,960 that. That's what it's for. I'm not there to entertain the general public. 609 00:46:36,000 --> 00:46:38,000 I'm there for my students. I just decided to make it go public 610 00:46:38,360 --> 00:46:43,639 if you will, okay, anyway, that's kind of a synopsis. I 611 00:46:43,679 --> 00:46:49,440 won't go into the optional method because it wasn't really a significant you know, 612 00:46:49,880 --> 00:46:55,559 too bad a significant changes in that. But there was something that was added 613 00:46:55,760 --> 00:47:01,719 in the twenty twenty three which is dealing with energy management systems EMS under two 614 00:47:01,719 --> 00:47:06,280 twenty dot seventy and this is saying, look, and this is under the 615 00:47:06,320 --> 00:47:09,079 standard method value way. It's under part three. It says, if an 616 00:47:09,199 --> 00:47:14,679 energy management system is used to limit the current to a feeder or service in 617 00:47:14,800 --> 00:47:17,960 accordance with seven fifty dot thirty and that's all those rules, and you meet 618 00:47:19,000 --> 00:47:22,119 all the rules for energy management, you're able to meet all these It says 619 00:47:22,199 --> 00:47:29,920 a single value equal to the maximum and peer set point of the EMS shall 620 00:47:30,000 --> 00:47:34,400 be permitted to be used in low calculations for these service or feeder. It 621 00:47:34,519 --> 00:47:38,639 says the set point value that's whatever you set it to not exceed in your 622 00:47:38,840 --> 00:47:43,920 energy management system. Mean it's going to shunt off loads, shut off loads, 623 00:47:44,039 --> 00:47:46,800 going to manage the system. If that's what you've got, then it 624 00:47:46,880 --> 00:47:53,239 says the set point values in the EMS shall be considered a continuous load for 625 00:47:53,360 --> 00:47:58,360 the purpose of load calculations. So whatever that value is that you set as 626 00:47:58,440 --> 00:48:02,760 that set point, you take that at one hundred and twenty five percent size 627 00:48:02,800 --> 00:48:07,840 everything accordingly. But you are able to use that value in the EMS system, 628 00:48:07,920 --> 00:48:13,239 and it is and you have to meet all the caveats in seven fifty. 629 00:48:14,199 --> 00:48:17,239 I have not today seen that. I know that that's new. I 630 00:48:17,360 --> 00:48:22,480 have not seen any buildings that follow that, which an example of this might 631 00:48:22,559 --> 00:48:27,760 be a big office building which the service might be quite large. When you 632 00:48:27,840 --> 00:48:30,280 do the calculation under the standard method most people going you are going to be 633 00:48:30,400 --> 00:48:36,000 using optionals anyway. But they do the standard methods, they calculate it all 634 00:48:36,039 --> 00:48:42,599 out. But then they have some type of system management system that is cycling 635 00:48:42,679 --> 00:48:45,559 off loads, limiting loads. It's going to keep the values to not exceed 636 00:48:45,639 --> 00:48:52,079 a certain level. Well, then obviously if that's the case and you meet 637 00:48:52,119 --> 00:48:58,880 all the caveats that are there in seven fifty for those EMS type systems, 638 00:49:00,039 --> 00:49:04,239 let's say that you meet it, you're compliant with that, you're an engineer, 639 00:49:04,280 --> 00:49:07,679 you design it. So maybe under the standard calculation it was four hundred 640 00:49:07,679 --> 00:49:13,159 amps, but under this EMS, your set point maybe is two hundred amps. 641 00:49:13,960 --> 00:49:16,480 Well, you can use that two hundred amps. Remember you're going to 642 00:49:16,519 --> 00:49:22,199 take it as continuous loads for sizing things like conductors and devices. But I'm 643 00:49:22,320 --> 00:49:30,199 able to use that set point. That's huge because that uses technology that's trying 644 00:49:30,280 --> 00:49:35,599 to create a way of, for lack of a better term, keeping the 645 00:49:35,719 --> 00:49:38,239 loads at a set point, shunted in some way, keeping it from getting 646 00:49:38,239 --> 00:49:42,960 to a certain point, and then you're designing your service or feeder load based 647 00:49:43,000 --> 00:49:49,800 on that. Right, So don't ever assume that that's a given, because 648 00:49:50,320 --> 00:49:52,400 you know, that's something that's going to definitely be an engineered system. That's 649 00:49:52,480 --> 00:49:57,880 not something that the normal electrician, every day sparky is going to be working 650 00:49:57,920 --> 00:50:00,719 with. Okay, so again, but it's there, and there's engineers that 651 00:50:00,760 --> 00:50:05,599 are flewing intoing that. So that's you know, that's good other than that, 652 00:50:05,760 --> 00:50:08,760 folks, everything else really didn't change too much. And my opinion was, 653 00:50:09,519 --> 00:50:15,559 how did I feel the flow went? And that's my flow. Now. 654 00:50:15,679 --> 00:50:17,039 The only other thing I will tell you into twenty that I think it 655 00:50:17,079 --> 00:50:22,239 makes a lot of sense is it did expand into a part six for healthcare 656 00:50:22,320 --> 00:50:29,039 facilities when it deals with receptacle loads and the demand factors you get for receptacle 657 00:50:29,079 --> 00:50:32,280 loads was introduced. We'll probably talk about that in another series. And then 658 00:50:32,360 --> 00:50:38,679 of course low calculations for Marina's boatyards, which is Part seven. All of 659 00:50:38,760 --> 00:50:45,519 that was added to article to twenty. And so again it stands out to 660 00:50:45,679 --> 00:50:54,079 me because it flat out tells you that we have our set parameters that we 661 00:50:54,159 --> 00:50:59,400 want you to do when it comes to the low calculations for healthcare facilities and 662 00:50:59,599 --> 00:51:04,920 a low calculations for marinas and things like that. Now, I will remind 663 00:51:05,000 --> 00:51:07,199 you that the healthcare facility you would you would use the standard method as you 664 00:51:07,239 --> 00:51:13,480 normally would. The only addition to Part six is the receptacle load aspect of 665 00:51:13,559 --> 00:51:15,920 it. And that's the same thing for Marina. You still got your low 666 00:51:15,000 --> 00:51:19,760 calcu You're gonna do understandard method, right, But when it comes to the 667 00:51:21,079 --> 00:51:27,360 predominant loading. When it comes to receptacles, you do get some allowances now 668 00:51:28,440 --> 00:51:34,039 under Part six and Part seven of Article two twenty. So that's a welcome 669 00:51:34,079 --> 00:51:37,639 addition. Definitely clears things up when it comes to receptacle loads, and it's 670 00:51:37,920 --> 00:51:43,079 kind of gets rid of those confusions that people would be all over the place 671 00:51:43,840 --> 00:51:47,599 in the different five fifty five for marinas and things like that. So are 672 00:51:47,639 --> 00:51:52,079 not five is five ft five? Yeah? It might be. So it 673 00:51:52,239 --> 00:51:55,599 gets you, you know, keeps you from being It helps reduce some of 674 00:51:55,639 --> 00:52:00,159 the confusion that you have out there, and so I'm all for anything that 675 00:52:00,199 --> 00:52:06,199 can make it so much easier for people that have to be able to navigate 676 00:52:06,239 --> 00:52:09,920 and flow in all that type of things. So welcome addition, folks. 677 00:52:10,000 --> 00:52:14,719 So that's my take to twenty. I think the structuring of that and what 678 00:52:14,840 --> 00:52:20,280 they did with that is probably my favorite change from a geeky calculation standpoint, 679 00:52:21,000 --> 00:52:27,039 That would be my favorite change in the twenty twenty excuse me, twenty twenty 680 00:52:27,159 --> 00:52:31,360 three edition, and I welcome that to the code panels to bring that clarity 681 00:52:32,440 --> 00:52:37,320 everywhere. But good job to the panel that did that for article to twenty. 682 00:52:38,199 --> 00:52:40,719 Great job.
