00:00:06,320 --> 00:00:36,119
Paul Ask Paul? What Up?
What Up? Everybody? This is Paul

2
00:00:36,119 --> 00:00:40,320
Abernathy. Welcome to another episode of
Let's Ask Paul the Podcast where I,

3
00:00:40,640 --> 00:00:45,439
Paul Abernathy, answer all of your
pressing, electrically code related questions that are

4
00:00:45,479 --> 00:00:51,960
submitted through our Let's Ask Paul podcast
portal, and that's over at Paul abernathy

5
00:00:52,439 --> 00:00:55,359
dot com. So no matter who
you are, you can go right over

6
00:00:55,399 --> 00:00:59,880
there and submit your questions. By
the way, we are changing our four

7
00:01:00,039 --> 00:01:03,040
romats when it comes to our fast
tracks. If you haven't heard, we

8
00:01:03,120 --> 00:01:08,840
have a new show that's starting on
June twenty eighth, and that new show

9
00:01:08,879 --> 00:01:15,200
at seven thirty pms Central Time.
That new show is a whole new format,

10
00:01:15,280 --> 00:01:19,000
whole new look, whole new theme. Everything's going to look totally different.

11
00:01:19,840 --> 00:01:23,439
And one of the beautiful things about
it is that you can submit questions

12
00:01:23,480 --> 00:01:29,680
that we will answer on that live
show by simply going to Paul Abernathy dot

13
00:01:29,760 --> 00:01:34,120
com. Now, Paul abernathy dot
com is our portal that we use to

14
00:01:34,799 --> 00:01:38,959
have people send questions and submit them
through everything. So that's the portal that

15
00:01:38,000 --> 00:01:42,439
we use. So I just want
to make sure that folks check that out

16
00:01:42,959 --> 00:01:47,480
at Paul Abernathy dot com and submit
your questions. Now, if you submit

17
00:01:47,599 --> 00:01:52,159
questions within twenty four hours of the
live show, it has a greater chance

18
00:01:52,159 --> 00:01:56,040
of it being answered on the actual
live show. Okay, that's important.

19
00:01:56,560 --> 00:02:00,159
If you're a fast Track student and
you're used to our Wednesday night sessions and

20
00:02:00,319 --> 00:02:04,040
we're kind of still doing Wednesday nights, but we're going away from zoom and

21
00:02:04,079 --> 00:02:07,120
we're going to be going back to
live streaming if you have questions in your

22
00:02:07,159 --> 00:02:12,039
program, again, it is fast
Tracks Live, so we are still dedicated

23
00:02:12,080 --> 00:02:15,280
to you the student. That's the
main main focus here, not just to

24
00:02:15,319 --> 00:02:20,080
do a live stream. It's is
the main focus is you students. What

25
00:02:20,280 --> 00:02:23,599
you do is you go to Paul
Abernathy dot com and you submit any question

26
00:02:23,639 --> 00:02:29,240
you have that you're encountering during your
studies in the fast Tracks program. If

27
00:02:29,240 --> 00:02:32,520
you don't understand something, again,
what do I always tell you? Right

28
00:02:32,639 --> 00:02:38,439
click, copy it and put it
in a word document. But here,

29
00:02:38,520 --> 00:02:42,199
just take it, copy it,
compile it, add any of your thoughts

30
00:02:42,199 --> 00:02:45,439
to it, and then go to
Paul abernathty dot com and just simply submit

31
00:02:45,479 --> 00:02:47,319
it through the portal. That way
it comes straight to me. You don't

32
00:02:47,319 --> 00:02:51,280
have to worry about it getting lost
in an email somewhere. It comes straight

33
00:02:51,319 --> 00:02:54,319
to me. And that's the best
way to send anything into us is through

34
00:02:54,319 --> 00:02:58,439
the Paul Abernathy dot com portal,
and it's be honest with you, it's

35
00:02:58,439 --> 00:03:00,719
the easiest way to do it.
It's pretty simple. Put your name in

36
00:03:00,759 --> 00:03:05,840
there, put your email addressing their, put your question in there, click

37
00:03:05,919 --> 00:03:08,360
that submit button. Boom And did
you know you can also listen to the

38
00:03:08,400 --> 00:03:12,639
podcast from that page as well.
Yep, be sure can't. So.

39
00:03:13,199 --> 00:03:16,960
Anyway, if anybody out there is
looking to get in a really good electrical

40
00:03:17,039 --> 00:03:22,879
exam prep program or your post licensing
programs, like you want to get deep

41
00:03:22,960 --> 00:03:27,039
dive into residential commercial grounding and bonding, do me a favor. Check out

44
00:03:38,120 --> 00:03:42,360
All right, folks, let's get
into the night's episode. I have a

45
00:03:42,439 --> 00:03:46,319
question. It was submitted and it's
kind of right up my alley. It's

46
00:03:46,759 --> 00:03:51,639
talking about grounding and bonding, and
so I thought it'd be great for this

47
00:03:51,680 --> 00:03:53,560
episode. So if you're the individual
that's submitted this, here you go,

48
00:03:53,840 --> 00:03:57,719
We're gonna take care of it for
you. All right. Here's what says

49
00:03:58,240 --> 00:04:01,360
says Hi Paul. I have a
question about a recent install I saw being

50
00:04:01,360 --> 00:04:08,599
done at a softball field. The
contractor ran one inch PBC conduit underground from

51
00:04:08,599 --> 00:04:13,680
the shed where the remote distribution panel
is at out to the new scoreboard.

52
00:04:14,439 --> 00:04:19,480
PVC was run from the panel out
the wall to a PVC LB, then

53
00:04:19,800 --> 00:04:27,480
transferred to rigid metal conduit that went
into the ground. Then it changed over

54
00:04:27,519 --> 00:04:35,199
again to PVC sweeps was attached to
the RMC and continued on underground. And

55
00:04:35,279 --> 00:04:39,399
of course I'm sure that was done
at the other end as well, and

56
00:04:39,439 --> 00:04:42,639
we'll talk about that because a couple
of the problems I have with that is

57
00:04:43,079 --> 00:04:48,879
you typically don't transition from PVC LB
to rigid metal conduit right the tapering of

58
00:04:48,920 --> 00:04:55,399
the threads of rigid and how you
do you? Also how are you doing

59
00:04:55,439 --> 00:04:59,240
that? And again I don't know
the details, but typically a PVC it's

60
00:04:59,279 --> 00:05:02,040
smooth because it's glue. You glue
the raceway into it. It's listed for

61
00:05:02,120 --> 00:05:06,519
PVC. So what did they do
they put that? Is, if there's

62
00:05:06,519 --> 00:05:13,399
an adapter out there that's a PVC
LB too, rigid. Okay, I'm

63
00:05:13,399 --> 00:05:19,680
not sure there maybe is, but
that's the first big red flag is transitioning

64
00:05:19,920 --> 00:05:25,800
from a PVC LB which is listed
for use with PVC, and now you're

65
00:05:26,000 --> 00:05:30,079
using it with RMC and then you're
ultimately changing over again to PVC to make

66
00:05:30,120 --> 00:05:33,600
that long run. Okay, all
right, So that's what's at stake here.

67
00:05:33,680 --> 00:05:38,720
Now, what I can tell you
so far is that nothing's because the

68
00:05:38,879 --> 00:05:44,279
LB turned. Nothing said that that
metal elbows that they're using rigid metal conduit

69
00:05:44,319 --> 00:05:48,920
elbows. Nothing said that they're lower
than eighteen inches blow grade, right,

70
00:05:49,120 --> 00:05:54,639
So we don't have to worry about
two fifty eighty six in number the exception

71
00:05:54,720 --> 00:05:58,079
number three or anything like that for
the eighteen inches. And because that doesn't

72
00:05:58,120 --> 00:06:00,319
sound like that's in play. If
you got your code book, make sure

73
00:06:00,319 --> 00:06:02,759
you pause, right, definitely want
to pause. And what you want to

74
00:06:02,759 --> 00:06:09,120
do is you want to go look
at two fifty dot and let me get

75
00:06:09,160 --> 00:06:11,879
my mouth. So we're here and
I got all new equipment here, so

76
00:06:12,040 --> 00:06:15,360
struggle struggling with it a little bit. Two fifty dot eighty six if you

77
00:06:15,480 --> 00:06:20,759
look at it, that is for
other conductor enclosures and race ways, and

78
00:06:20,839 --> 00:06:26,439
you have an allowance and exception number
three, item number one that would allow

79
00:06:26,519 --> 00:06:30,160
you to be able to not have
to bond those metal raceways and things like

80
00:06:30,199 --> 00:06:34,000
that. Okay, all right,
but that doesn't sound like what's going on

81
00:06:34,079 --> 00:06:36,920
here. That doesn't sound like what's
going on here. So what we're going

82
00:06:36,959 --> 00:06:40,199
to look at for the gentleman is
we're going to be looking at at two

83
00:06:40,199 --> 00:06:44,519
fifty dot four. Now, two
fifty dot four is the general requirements.

84
00:06:44,560 --> 00:06:49,800
Okay, these are to these What
we're looking at here is these are the

85
00:06:49,879 --> 00:06:59,040
prescriptive methods contained in two fifty shall
be followed and complied with the performance requirements

86
00:06:59,079 --> 00:07:02,040
of this section, which is section
four. So throughout the code your have

87
00:07:02,160 --> 00:07:06,560
prescriptive things you have to do.
In two fifty, you have prescriptive things

88
00:07:06,600 --> 00:07:12,519
telling you what to do, and
in doing that you basically meet the performance

89
00:07:12,560 --> 00:07:15,959
requirements that are here in two fifty
dot four. So, well one we

90
00:07:15,959 --> 00:07:17,279
want to look at Obviously, this
is a grounded system. So if you

91
00:07:17,319 --> 00:07:21,199
have your codebooks, we want to
look at two fifty dot four. A

92
00:07:23,279 --> 00:07:29,120
four and a three, Now a
four and a three. A three is

93
00:07:29,199 --> 00:07:32,720
bonding of electrical equipment, and then
of course a four is bonding of electrically

94
00:07:32,759 --> 00:07:38,839
conductive material and other equipments. So
let's look at A three first. Okay.

95
00:07:39,519 --> 00:07:42,519
So A three says, if you
have your codebook and I'll read it

96
00:07:42,519 --> 00:07:46,639
till you don't worry, it says
bonding of electrical equipment. It says normally

97
00:07:46,800 --> 00:07:57,879
non current currying conductive materials in closing
electrical conductors, okay, or equipment or

98
00:07:58,000 --> 00:08:05,240
forming part of such equipment shall be
connected together and to the electrical supply source

99
00:08:05,399 --> 00:08:09,000
in a manner that establishes an effective
ground fault current path. Okay, So

100
00:08:09,079 --> 00:08:13,240
we have to all metal parts that
are non current curring. This is why

101
00:08:13,279 --> 00:08:18,720
we bond everything together and things like
that. And then of course A four

102
00:08:18,959 --> 00:08:26,000
says bonding of electrical conductive material and
other equipment says normally non current carrying electrical

103
00:08:26,040 --> 00:08:33,039
conductive material and obviously that's what the
rigid metal conduit is, normally non current

104
00:08:33,039 --> 00:08:39,240
carrying, obviously, and it's that
are likely to become energized. Well,

105
00:08:39,279 --> 00:08:45,600
it's housing conductors. Okay, so
if you know, we'll read the next

106
00:08:45,600 --> 00:08:48,200
part of this question. But I'm
just kind of giving you the scope period.

107
00:08:48,200 --> 00:08:52,360
It is housing these conductors shall be
connected together and to the electrical supply

108
00:08:52,519 --> 00:08:58,919
source in a manner that establishes an
effective ground current ground fault current path.

109
00:09:00,360 --> 00:09:03,200
All right, So the bigger one
for me is a three. I am

110
00:09:03,240 --> 00:09:09,519
required, okay if the material isn't
closing conductors, which these raceways are.

111
00:09:09,120 --> 00:09:13,279
Okay, the metal raceway that we're
talking about, the metal portion, which

112
00:09:13,320 --> 00:09:18,919
is the RMC of this installation,
it has to be connected to the electrical

113
00:09:18,919 --> 00:09:24,720
supply source in a manner that establishes
an effective ground fault current campad right.

114
00:09:24,360 --> 00:09:28,399
Okay, Well it doesn't. It's
floating, it's isolating, and obviously two

115
00:09:28,480 --> 00:09:33,600
fifty eighty six doesn't come into play
because it's not eighteen inches below grade.

116
00:09:33,879 --> 00:09:35,720
Right, So that's a problem.
So let's go on and read the rest

117
00:09:35,720 --> 00:09:39,919
of this question and see if we
didn't answer what they wanted. Here says

118
00:09:41,039 --> 00:09:48,320
my question considering that section of RMC
with PBC on either side, because that

119
00:09:48,559 --> 00:09:56,039
RMC is not bonded, if the
wire insulation gets damaged during the pull or

120
00:09:56,080 --> 00:10:00,960
the insulation broke down over time,
I think this could be a potential hazard

121
00:10:01,159 --> 00:10:05,080
with your knowledge of article two fifty
and I'm looking for more insight on what

122
00:10:05,120 --> 00:10:09,720
the NBC has to say about this
type of installation. Thanks, thanks God

123
00:10:09,759 --> 00:10:13,960
bless. Okay, so here's the
reality. You're absolutely right. What's going

124
00:10:15,039 --> 00:10:20,559
to happen is you have a raceway
that is exposed to people coming in contact

125
00:10:20,639 --> 00:10:28,840
with it, you get a damaged
conductor. It energizes that metal small portion

126
00:10:28,919 --> 00:10:33,440
of RMC, and it's not going
to clear it over current device. It's

127
00:10:33,519 --> 00:10:37,720
not it's not bonded. So if
they did that on that end, they

128
00:10:39,200 --> 00:10:45,399
need to bond that those small portions
of the RMC back to the source.

129
00:10:46,200 --> 00:10:50,600
Right And in this case, if
they're running, obviously they're gonna have an

130
00:10:50,600 --> 00:10:54,240
equipment ground that runs with it,
that runs into PBC running all the way,

131
00:10:54,679 --> 00:10:58,440
they have to figure out how Obviously
this is inside of the race way,

132
00:10:58,440 --> 00:11:01,720
so they're gonna have to do bonding
jumpers outside. And again I don't

133
00:11:01,759 --> 00:11:05,120
know how far it comes from that
panel down, but all I can say

134
00:11:05,200 --> 00:11:09,519
is above ground. That's a poor
choice to use regid metal conduit above ground

135
00:11:09,960 --> 00:11:16,039
and try to connect it to a
PVC LB. And now you've got a

136
00:11:16,080 --> 00:11:20,720
metal component that, if it gets
energized, is certainly not going to clear

137
00:11:20,720 --> 00:11:22,679
a breaker. It's just going to
stay hot until you come in contact with

138
00:11:22,720 --> 00:11:26,720
it. Okay, So You're absolutely
right that as a problem. So I

139
00:11:26,759 --> 00:11:33,919
would cite to fifty dot four,
A three and a four, and I'm

140
00:11:33,960 --> 00:11:37,600
sure we could find other references in
there. But that's again, it's about

141
00:11:37,639 --> 00:11:39,799
as good as you need in order
to be able to tell them they're doing

142
00:11:39,039 --> 00:11:41,879
and doing a little something wrong if
they need to look at that right.

143
00:11:43,639 --> 00:11:46,679
So hopefully you got something out of
that, folks. That was a great

144
00:11:46,679 --> 00:11:50,480
one that was submitted, and it
wasn't a long one. I guess it's

145
00:11:50,480 --> 00:11:56,080
about ten or eleven minutes we did
on that podcast, but nothing else that

146
00:11:56,240 --> 00:11:58,919
that really we need to do for
that one. That's about it for that.

147
00:12:01,639 --> 00:12:05,639
So remember, folks, if you
have any questions, just go over

148
00:12:05,679 --> 00:12:09,639
to Paul Aberdey dot com. Feel
free to submit and we will answer them

149
00:12:09,639 --> 00:12:15,919
on a podcast, maybe even during
