1
00:00:08,707 --> 00:00:10,221
Welcome to my house.

2
00:00:10,778 --> 00:00:12,531
This is a show for people with problems.

3
00:00:12,849 --> 00:00:15,478
Home improvement problems that is, and for people

4
00:00:15,478 --> 00:00:17,561
who want common sense guidance on how to

5
00:00:17,561 --> 00:00:20,262
build green and live a more sustainable lifestyle.

6
00:00:20,501 --> 00:00:22,646
Send an email a mighty house crew is

7
00:00:22,646 --> 00:00:24,988
on the job. This is

8
00:00:25,838 --> 00:00:26,553
my house.

9
00:00:29,411 --> 00:00:31,079
Alright. We're back and today.

10
00:00:31,889 --> 00:00:34,701
Where we've got another instant request from a

11
00:00:35,078 --> 00:00:36,433
a listener a viewer,

12
00:00:37,150 --> 00:00:37,469
a

13
00:00:38,346 --> 00:00:39,882
subscriber, 1 of those

14
00:00:40,354 --> 00:00:42,823
But anyway, we got an email from someone

15
00:00:42,823 --> 00:00:43,323
and

16
00:00:43,779 --> 00:00:46,031
they kinda we're getting confused about

17
00:00:46,487 --> 00:00:49,217
grounding and bonding, which I

18
00:00:49,529 --> 00:00:51,048
you have to say most people do.

19
00:00:51,927 --> 00:00:53,764
So we're gonna talk about that. But before

20
00:00:53,764 --> 00:00:55,043
we do that, make sure you hit that

21
00:00:55,043 --> 00:00:57,120
subscribe button, ding on the bell that way

22
00:00:57,120 --> 00:01:00,272
get notified next... Time, we post something, and

23
00:01:01,130 --> 00:01:02,728
go ahead and leave a comment below because

24
00:01:02,888 --> 00:01:04,965
I know this is a very interesting topic.

25
00:01:07,137 --> 00:01:08,096
If you're a geek,

26
00:01:08,975 --> 00:01:12,010
we'll just kinda clarify that right there. Because,

27
00:01:12,490 --> 00:01:14,014
this we're gonna go into the weeds. I

28
00:01:14,014 --> 00:01:15,442
know. We're gonna try to stay out of

29
00:01:15,442 --> 00:01:15,839
the weeds,

30
00:01:16,632 --> 00:01:18,378
but we may end up there. So...

31
00:01:19,092 --> 00:01:19,251
Alright.

32
00:01:20,139 --> 00:01:21,809
Do you wanna start with the share right

33
00:01:21,809 --> 00:01:24,116
away? Yep. Yeah. Let's go with that. Okay.

34
00:01:24,355 --> 00:01:26,821
Let's let's start with the share screen and

35
00:01:26,821 --> 00:01:27,878
go to the first

36
00:01:31,217 --> 00:01:32,813
there we go. There's our first.

37
00:01:33,929 --> 00:01:36,801
So we'll just clarify that grounding and bonding.

38
00:01:37,040 --> 00:01:38,337
I mean, they're 2 different

39
00:01:39,128 --> 00:01:39,628
processes

40
00:01:40,162 --> 00:01:42,889
or requirements on your electrical system

41
00:01:43,344 --> 00:01:45,014
and are extremely important in your home.

42
00:01:46,463 --> 00:01:46,963
But

43
00:01:47,500 --> 00:01:49,117
they seem redundant

44
00:01:50,213 --> 00:01:51,569
because of where you do some of the

45
00:01:51,569 --> 00:01:52,686
connections? U.

46
00:01:53,419 --> 00:01:56,213
But it's not. It still has... There's, like,

47
00:01:56,373 --> 00:01:59,326
different reasons for the 2. Correct. So...

48
00:02:00,284 --> 00:02:01,821
And if when doing

49
00:02:02,373 --> 00:02:04,201
some research for this, You go to the

50
00:02:04,281 --> 00:02:07,381
N epa's website, the National Fire protection agency.

51
00:02:08,096 --> 00:02:10,957
And if you read their definitions of of,

52
00:02:11,608 --> 00:02:12,084
rounding,

53
00:02:13,433 --> 00:02:15,416
you'll probably come away even more confused.

54
00:02:16,527 --> 00:02:18,510
And it was simply because they keep saying,

55
00:02:18,669 --> 00:02:20,995
make sure you take this grounded bonded to

56
00:02:20,995 --> 00:02:22,995
there and it's... So they're... I think they

57
00:02:22,995 --> 00:02:24,115
need mean connect,

58
00:02:24,675 --> 00:02:25,474
not bond.

59
00:02:26,835 --> 00:02:29,569
Secure, they're saying bond like Connect. So then

60
00:02:29,569 --> 00:02:31,490
now that word is getting overused and then

61
00:02:31,490 --> 00:02:34,530
it becomes even more muddled, more confusing.

62
00:02:35,090 --> 00:02:37,810
So I think it's important to understand that.

63
00:02:38,384 --> 00:02:40,874
Grounding can also be called earth

64
00:02:41,250 --> 00:02:43,240
depending on where you in the country. Right.

65
00:02:43,479 --> 00:02:43,638
Right?

66
00:02:44,434 --> 00:02:46,916
And it's also how the system is wired

67
00:02:46,916 --> 00:02:48,823
to create what they call it ground fault

68
00:02:48,823 --> 00:02:49,220
circuit.

69
00:02:50,729 --> 00:02:52,874
So that's the pathway to ground.

70
00:02:53,764 --> 00:02:57,034
Yes. You're lighting, your outlet, your mechanical. Right?

71
00:02:58,310 --> 00:03:00,223
So like, you know, think about an outlet.

72
00:03:00,383 --> 00:03:01,898
Right? You have a hot neutral in a

73
00:03:01,898 --> 00:03:02,217
ground.

74
00:03:04,540 --> 00:03:05,676
Yes. Now

75
00:03:06,209 --> 00:03:08,196
if if you live in the Chicago land

76
00:03:08,196 --> 00:03:10,660
area and you have conduit it, you've got

77
00:03:10,660 --> 00:03:12,193
your hot, your neutral

78
00:03:12,504 --> 00:03:15,221
and then the the metal box, the metal

79
00:03:15,221 --> 00:03:15,780
conduit it,

80
00:03:16,499 --> 00:03:19,455
and that becomes your ground. That's why when

81
00:03:19,455 --> 00:03:21,230
you look at a the extension cords that

82
00:03:21,230 --> 00:03:22,909
the rest of the country uses called Bro

83
00:03:22,909 --> 00:03:23,150
x.

84
00:03:23,710 --> 00:03:26,430
They have that ground wire in there. Mh.

85
00:03:26,830 --> 00:03:27,330
That's

86
00:03:27,964 --> 00:03:29,878
taking place of what we have in our

87
00:03:29,878 --> 00:03:31,633
area of of metal conduit.

88
00:03:32,191 --> 00:03:32,691
So

89
00:03:33,068 --> 00:03:34,823
those those are interchangeable,

90
00:03:35,222 --> 00:03:37,136
and so that's providing the ground.

91
00:03:38,028 --> 00:03:38,903
Back to the panel.

92
00:03:39,540 --> 00:03:40,518
Right. So

93
00:03:41,291 --> 00:03:42,724
if you have... If you don't have Rome

94
00:03:42,724 --> 00:03:44,475
x, that's why you don't always see a

95
00:03:44,475 --> 00:03:46,955
ground in there because the the the pipe

96
00:03:46,955 --> 00:03:49,815
is... The the Emt, the conduit does that

97
00:03:49,815 --> 00:03:51,642
for you. But a good point on that.

98
00:03:51,801 --> 00:03:53,310
Those if you were to remove the outlet

99
00:03:53,310 --> 00:03:55,473
from the box. And say it's still hot

100
00:03:55,473 --> 00:03:57,542
and you plug something in, your outlet may

101
00:03:57,542 --> 00:03:59,395
still work, but it's no longer ground

102
00:03:59,770 --> 00:04:01,521
because you could removed it from that metal.

103
00:04:02,094 --> 00:04:03,690
Correct. A lot of times you'll see a

104
00:04:03,690 --> 00:04:05,286
small green wire go from the back of

105
00:04:05,286 --> 00:04:07,063
the outlet to the back of the box

106
00:04:07,282 --> 00:04:08,798
so that you pull the outlet out, the

107
00:04:08,798 --> 00:04:09,836
outlet is still rounded.

108
00:04:10,488 --> 00:04:11,625
Right. And,

109
00:04:12,318 --> 00:04:15,183
you know, they... That outlook could, like, get

110
00:04:15,183 --> 00:04:17,649
perfectly placed where the screws not bonded to

111
00:04:17,649 --> 00:04:19,735
or sitting on their tight enough. And it

112
00:04:19,735 --> 00:04:21,334
can actually float in there and all of

113
00:04:21,334 --> 00:04:23,814
a sudden that outlet no longer ground. Would

114
00:04:23,814 --> 00:04:25,334
show an open ground when you do the

115
00:04:25,334 --> 00:04:27,824
test. Correct. So that's why you'd... You'll do

116
00:04:27,824 --> 00:04:29,996
the jumper off the outlet back to the

117
00:04:30,213 --> 00:04:30,611
to the,

118
00:04:32,284 --> 00:04:34,195
to the box. Right. And I can see

119
00:04:34,195 --> 00:04:36,202
that a lot if you're doing say kitchen

120
00:04:36,202 --> 00:04:38,435
outlets with a grad packs splash and you've

121
00:04:38,435 --> 00:04:40,509
got spacers. And or you're relying on that

122
00:04:40,509 --> 00:04:42,343
screw to make good contact with the plaster

123
00:04:42,343 --> 00:04:44,257
ring in the back, and that plaster has

124
00:04:44,257 --> 00:04:45,782
to make good contact check with the box

125
00:04:45,782 --> 00:04:47,208
and the box. So I.

126
00:04:48,080 --> 00:04:50,220
Correct. So 1 of the primary purposes of

127
00:04:50,220 --> 00:04:52,415
the grounding goes for detection faults and like

128
00:04:52,772 --> 00:04:55,339
system, and it provides a path recurrence back

129
00:04:55,792 --> 00:04:57,700
from that fall point through the ground to

130
00:04:57,700 --> 00:04:59,051
the source neutral point.

131
00:05:00,258 --> 00:05:03,042
Which is all that's right here. Yeah. So

132
00:05:03,042 --> 00:05:05,111
when you think about that ground, all that

133
00:05:05,111 --> 00:05:06,383
stuff in the ground,

134
00:05:07,354 --> 00:05:09,508
it's also going to your neutral bar, but

135
00:05:09,508 --> 00:05:12,380
it's giving it path to earth or path

136
00:05:12,380 --> 00:05:12,939
to ground.

137
00:05:14,949 --> 00:05:17,270
So your neutral is always tied to that

138
00:05:17,270 --> 00:05:19,509
neutral bar. You've got your other bar. That

139
00:05:19,509 --> 00:05:21,270
1 on the bottom of that service panel

140
00:05:21,270 --> 00:05:22,410
would be actually

141
00:05:22,710 --> 00:05:23,750
something for you to put.

142
00:05:24,404 --> 00:05:25,838
You know, if you had other pieces of

143
00:05:25,838 --> 00:05:27,910
equipment, whether it's a phone box cable or

144
00:05:27,910 --> 00:05:29,901
whatever those are you... Where you're gonna re

145
00:05:29,901 --> 00:05:30,459
attach those.

146
00:05:34,696 --> 00:05:36,129
So I think most places like in the

147
00:05:36,289 --> 00:05:38,598
Chicago area, you can actually ground which it

148
00:05:38,598 --> 00:05:40,032
shows here is like to your water pipe.

149
00:05:41,161 --> 00:05:42,831
Yeah for the most part, you got 3

150
00:05:42,831 --> 00:05:44,978
quarter or 1 inch copper k run out

151
00:05:44,978 --> 00:05:46,887
for your water service so that's your ground,

152
00:05:47,125 --> 00:05:48,739
did put strap or sale

153
00:05:49,129 --> 00:05:51,127
clamp on that and that your ground.

154
00:05:51,766 --> 00:05:53,843
Correct. We use plastic for our water lines,

155
00:05:54,163 --> 00:05:55,761
so we have to put in the ground

156
00:05:55,761 --> 00:05:56,160
rods.

157
00:05:57,054 --> 00:05:57,932
Which are shown there.

158
00:05:58,571 --> 00:05:59,049
Right here.

159
00:05:59,848 --> 00:06:02,103
And then because we do all concrete block

160
00:06:02,242 --> 00:06:02,960
and slam,

161
00:06:03,519 --> 00:06:05,608
all of our rebar has to be We

162
00:06:05,608 --> 00:06:07,996
have a building ground or steel, building steel.

163
00:06:10,862 --> 00:06:11,362
So

164
00:06:11,738 --> 00:06:12,853
on these ground rods,

165
00:06:14,061 --> 00:06:15,594
there's a minimum of

166
00:06:16,128 --> 00:06:18,194
2 that it's required because there's no way

167
00:06:18,194 --> 00:06:20,897
to really test the impedance of these. So

168
00:06:20,897 --> 00:06:23,540
now that's why they're requiring 2. Minimum of

169
00:06:23,540 --> 00:06:26,500
6 feet apart and 8 feet long. So,

170
00:06:27,620 --> 00:06:29,300
obviously, different parts of the country, you can't

171
00:06:29,300 --> 00:06:31,630
get an 8 foot ground rod in. So

172
00:06:31,630 --> 00:06:34,168
that's why you've got these different types of

173
00:06:34,168 --> 00:06:35,278
wires, plates,

174
00:06:36,309 --> 00:06:38,053
there's all different sizes. And you've just... If

175
00:06:38,053 --> 00:06:38,950
you go to the

176
00:06:39,259 --> 00:06:41,819
any nec c that'll show you exactly all

177
00:06:41,819 --> 00:06:44,300
your different options for getting proper grounding.

178
00:06:47,995 --> 00:06:48,495
So

179
00:06:49,675 --> 00:06:50,474
with that,

180
00:06:52,154 --> 00:06:52,394
this...

181
00:06:53,035 --> 00:06:55,035
I think this was part pretty interesting. The

182
00:06:55,035 --> 00:06:56,714
way you have to tie this in with

183
00:06:56,714 --> 00:07:00,469
your building steel. Mh. In in your area

184
00:07:00,469 --> 00:07:02,536
you're saying that this out actually goes up

185
00:07:02,536 --> 00:07:03,672
and then ties in

186
00:07:04,047 --> 00:07:05,637
to the... I would actually come up next

187
00:07:05,637 --> 00:07:06,694
to our where you're

188
00:07:07,162 --> 00:07:09,302
panel his or your service entrance so blow

189
00:07:09,302 --> 00:07:10,571
a hole in the block. And if you

190
00:07:10,571 --> 00:07:12,077
got a really good guy, which mine was.

191
00:07:12,236 --> 00:07:14,059
He put a... They put up a plaster

192
00:07:14,059 --> 00:07:16,226
ring. 2 gang class rings so that there's

193
00:07:16,226 --> 00:07:18,381
a cover on there. We now anybody needs

194
00:07:18,381 --> 00:07:20,877
to attach building steel for for ground

195
00:07:21,335 --> 00:07:23,671
and our bonding, which we'll get to next

196
00:07:23,984 --> 00:07:25,822
then that way they have some place that

197
00:07:25,822 --> 00:07:28,458
is all... It's guaranteed to work. It's guaranteed.

198
00:07:28,618 --> 00:07:29,576
It's all tied together.

199
00:07:30,216 --> 00:07:30,375
Right.

200
00:07:31,189 --> 00:07:32,947
So Okay. And like You said, that's a

201
00:07:32,947 --> 00:07:35,744
low impedance path or static charges surges caused

202
00:07:35,744 --> 00:07:37,662
my environment and anything, and it's getting it

203
00:07:37,662 --> 00:07:39,420
back to ground to the earth.

204
00:07:40,153 --> 00:07:41,447
Correct. Alright. So

205
00:07:42,139 --> 00:07:42,957
that is

206
00:07:43,331 --> 00:07:43,807
grounding.

207
00:07:44,601 --> 00:07:44,840
Right.

208
00:07:47,620 --> 00:07:49,209
So that brings us to bonding.

209
00:07:51,446 --> 00:07:52,557
So bonding,

210
00:07:53,033 --> 00:07:55,414
bonding is the practice of intentionally. I like

211
00:07:55,414 --> 00:07:57,874
this this definition actually came up wikipedia.

212
00:07:58,683 --> 00:08:01,546
Okay. Electrical bonding is the practice of intentionally

213
00:08:01,546 --> 00:08:04,409
electrically connecting all exposed metal items,

214
00:08:04,886 --> 00:08:08,408
not designed to carry electricity in a room

215
00:08:08,798 --> 00:08:11,829
or building as protection from electric shock.

216
00:08:12,627 --> 00:08:15,520
Bonding is also used to minimize electrical arcing

217
00:08:15,578 --> 00:08:17,673
between metal services with electrical

218
00:08:18,051 --> 00:08:19,123
potential differences.

219
00:08:20,532 --> 00:08:20,850
Yes.

220
00:08:22,361 --> 00:08:25,223
So so do you wanna talk about, let's

221
00:08:25,223 --> 00:08:26,655
go to a... I just jump straight to

222
00:08:26,655 --> 00:08:27,791
a swimming pool

223
00:08:28,499 --> 00:08:30,643
And and what the potential is there.

224
00:08:31,358 --> 00:08:34,002
Okay. Got you wanna explain that 1

225
00:08:34,773 --> 00:08:36,123
and how you have to do that, at

226
00:08:36,123 --> 00:08:38,284
least you know, for swimming pools so that

227
00:08:38,284 --> 00:08:41,304
that way... Well, ours ours is probably a

228
00:08:41,304 --> 00:08:43,632
little different than yours at some respects. So

229
00:08:43,768 --> 00:08:45,778
because our our building steel

230
00:08:46,088 --> 00:08:48,235
goes through our pool decks and our pool

231
00:08:48,235 --> 00:08:48,633
shelves,

232
00:08:49,349 --> 00:08:51,894
all of that rebar is bonded together to

233
00:08:51,894 --> 00:08:54,254
begin with. But then we have another bond

234
00:08:54,774 --> 00:08:56,712
has to go from the pool shell

235
00:08:57,651 --> 00:08:59,409
directly to the equipment so that we have

236
00:08:59,409 --> 00:09:02,366
an equipment bond so that there's no conduction

237
00:09:02,366 --> 00:09:04,776
through water through pipe whatever so we have

238
00:09:04,776 --> 00:09:07,407
an equipment bond tying that bolts out.

239
00:09:08,444 --> 00:09:10,038
Is that when I learned about bonding, I

240
00:09:10,038 --> 00:09:12,032
was actually building a job in in verbiage

241
00:09:12,032 --> 00:09:12,271
ridge,

242
00:09:12,923 --> 00:09:15,387
and I had a an an electrical inspector

243
00:09:15,387 --> 00:09:18,249
fail a bathroom inspection because the tub with

244
00:09:18,249 --> 00:09:20,474
my whirlpool tub was not bonded to the

245
00:09:20,474 --> 00:09:20,792
drain.

246
00:09:22,159 --> 00:09:23,834
And I had never done that before, And

247
00:09:23,914 --> 00:09:25,668
I may asked him, you know, what's... I

248
00:09:25,668 --> 00:09:27,822
don't understand what's the point of this. Right.

249
00:09:28,061 --> 00:09:30,215
And fortunately, it was a good inspector warrant

250
00:09:30,215 --> 00:09:31,810
at least I asked the question properly.

251
00:09:32,940 --> 00:09:35,327
And he explained to me that because the

252
00:09:35,327 --> 00:09:37,716
drain is brass, my water line is copper,

253
00:09:38,034 --> 00:09:39,387
there's chrome on top of that,

254
00:09:40,198 --> 00:09:43,220
brass and copper do not carry electricity at

255
00:09:43,220 --> 00:09:46,003
the same potential. There's a variance in how

256
00:09:46,003 --> 00:09:47,673
much electricity will flow on them.

257
00:09:48,804 --> 00:09:50,804
If you had a pacemaker, and you were

258
00:09:50,804 --> 00:09:51,304
holding

259
00:09:52,084 --> 00:09:54,084
the shower valve, which happens to be brass,

260
00:09:54,245 --> 00:09:55,605
and you stepped down the drain,

261
00:09:56,579 --> 00:09:58,177
or the water line, you know, and they

262
00:09:58,177 --> 00:10:00,255
connected to the copper, it literally could send

263
00:10:00,255 --> 00:10:03,372
milliamps through your body. Mh. Which most people

264
00:10:03,372 --> 00:10:05,862
would never notice us. Right. But if you

265
00:10:05,862 --> 00:10:08,249
had a pacemaker, it could stop it. Yeah.

266
00:10:09,045 --> 00:10:11,114
And that's where all this kinda came from,

267
00:10:11,750 --> 00:10:13,501
and it started making a lot more sense

268
00:10:13,501 --> 00:10:15,509
after he told me that. And I also

269
00:10:15,509 --> 00:10:16,870
appreciated that. You know what Mean It's so?

270
00:10:17,110 --> 00:10:19,429
Right? No. I get it. And never had

271
00:10:19,429 --> 00:10:20,709
a problem behind since.

272
00:10:21,990 --> 00:10:23,350
Because he took the time to explain it

273
00:10:23,350 --> 00:10:25,036
to you. Yeah. Well, as when you go

274
00:10:25,036 --> 00:10:27,102
online, it gets kinda confusing. So what's the

275
00:10:27,102 --> 00:10:29,724
practical reason. Right? What is it really helping?

276
00:10:30,280 --> 00:10:30,677
Right.

277
00:10:31,409 --> 00:10:33,327
That's what it is. It's really about trying

278
00:10:33,327 --> 00:10:33,987
to keep

279
00:10:34,525 --> 00:10:36,144
the potential the same

280
00:10:36,763 --> 00:10:38,840
in all your dissimilar metals in your home.

281
00:10:39,575 --> 00:10:42,294
Or business for that matter. Right. But this

282
00:10:42,294 --> 00:10:44,475
1, we're showing where we have our ground

283
00:10:44,774 --> 00:10:46,455
over I in the bottom left, and then

284
00:10:46,455 --> 00:10:48,786
that goes to your neutral terminal block But

285
00:10:48,786 --> 00:10:50,688
you can see the bond jumper on the

286
00:10:50,688 --> 00:10:52,748
chase way all the way to the right

287
00:10:52,748 --> 00:10:55,125
and to the left, there's where you're bonding.

288
00:10:56,011 --> 00:10:57,995
So now that case is gonna carry the

289
00:10:57,995 --> 00:10:59,502
same. They do the same thing when they

290
00:10:59,502 --> 00:11:00,636
get into the sub.

291
00:11:01,088 --> 00:11:03,167
They put another bond on there. If I

292
00:11:03,167 --> 00:11:05,392
was to touch the Chase or the panel

293
00:11:05,392 --> 00:11:05,631
below,

294
00:11:06,505 --> 00:11:08,651
the boxes are gonna be exactly the same.

295
00:11:09,287 --> 00:11:11,274
I'm not gonna have a different in potential.

296
00:11:12,403 --> 00:11:13,598
Correct. That's your service.

297
00:11:14,554 --> 00:11:16,307
So that next slide, I think is really

298
00:11:16,307 --> 00:11:18,060
good for more more for homeowners.

299
00:11:19,429 --> 00:11:21,110
This is what needs to be done in

300
00:11:21,110 --> 00:11:21,830
your utility.

301
00:11:24,470 --> 00:11:24,970
And

302
00:11:25,269 --> 00:11:27,269
a lot of the home inspectors today are

303
00:11:27,269 --> 00:11:28,730
picking up on this not

304
00:11:29,043 --> 00:11:31,927
not the municipal inspectors, but the

305
00:11:32,460 --> 00:11:34,049
home inspectors that come in when you buy

306
00:11:34,049 --> 00:11:35,241
a house or selling a house,

307
00:11:35,876 --> 00:11:38,199
they're picking up on this now. And Well

308
00:11:38,199 --> 00:11:39,959
if you look at the bottom of the

309
00:11:39,959 --> 00:11:41,959
water heater, look who copyrighted did this. So

310
00:11:41,959 --> 00:11:43,799
we have to give them credit. Oh, hey,

311
00:11:44,039 --> 00:11:44,360
Na.

312
00:11:44,854 --> 00:11:44,933
Yeah.

313
00:11:45,808 --> 00:11:49,229
Yep international. Right? Yeah. So we've done a

314
00:11:49,229 --> 00:11:50,979
lot of stuff with Na in the past

315
00:11:50,979 --> 00:11:51,479
and

316
00:11:51,948 --> 00:11:53,779
you know, done some of their training and

317
00:11:53,779 --> 00:11:55,610
and had them on on even in the

318
00:11:55,610 --> 00:11:58,157
past. You know, So I thought this was

319
00:11:58,157 --> 00:11:59,215
actually a really good

320
00:12:00,164 --> 00:12:02,319
drawing of what we're trying to talk about

321
00:12:02,319 --> 00:12:05,193
and probably more importantly is when you see

322
00:12:05,193 --> 00:12:07,508
that water line on the top there and

323
00:12:07,508 --> 00:12:08,626
where the water meter is.

324
00:12:09,599 --> 00:12:11,198
You see they put a jumper across.

325
00:12:11,837 --> 00:12:11,997
Right.

326
00:12:12,716 --> 00:12:14,394
Could you pull that water meter out as

327
00:12:14,394 --> 00:12:14,874
what happens.

328
00:12:16,232 --> 00:12:18,470
That... Yeah. You no longer have breaking your

329
00:12:18,470 --> 00:12:20,400
bonds. So you have to put the jumper

330
00:12:20,400 --> 00:12:22,554
over the meter. Same thing with your water

331
00:12:22,554 --> 00:12:24,388
heater just because the 2 lines go in

332
00:12:24,388 --> 00:12:25,984
and there doesn't mean they're gonna have the

333
00:12:25,984 --> 00:12:28,137
same potential so you jumper across over the

334
00:12:28,137 --> 00:12:28,536
water heater.

335
00:12:29,664 --> 00:12:32,363
Right. Because in fact is that for some

336
00:12:32,363 --> 00:12:33,815
reason, you drain that out

337
00:12:34,347 --> 00:12:36,196
and not now you have the

338
00:12:36,743 --> 00:12:38,491
you have... You don't have the water to

339
00:12:38,491 --> 00:12:39,841
be able to complete that connection.

340
00:12:40,636 --> 00:12:42,622
I guess the 1 thing that's missing here

341
00:12:42,622 --> 00:12:43,122
is

342
00:12:43,908 --> 00:12:45,972
if this is a gas dryer,

343
00:12:46,449 --> 00:12:48,378
they also require you to go from

344
00:12:48,989 --> 00:12:51,053
1 side, 1 pipe down to the gas

345
00:12:51,053 --> 00:12:52,244
pipe also.

346
00:12:53,212 --> 00:12:54,643
Yeah. I didn't find... I could not find

347
00:12:54,643 --> 00:12:56,550
any that actually showed the gas pipe, but

348
00:12:56,550 --> 00:12:58,060
that's... It I made that comment earlier, but,

349
00:12:58,139 --> 00:12:59,808
yes, you'd wanna bond gas pipe.

350
00:13:00,841 --> 00:13:01,341
So

351
00:13:02,129 --> 00:13:04,681
These are... Yeah. These are fairly important here

352
00:13:04,681 --> 00:13:06,356
that you gotta watch out for this 1,

353
00:13:06,675 --> 00:13:07,951
and then you should have 1 more that

354
00:13:07,951 --> 00:13:09,169
goes down to the gas

355
00:13:09,706 --> 00:13:11,381
if you've got a gas water heater.

356
00:13:12,113 --> 00:13:14,817
Mh. And and that way your your tying

357
00:13:14,817 --> 00:13:15,612
all that together,

358
00:13:16,327 --> 00:13:18,974
and you're eliminating all those potentials

359
00:13:19,906 --> 00:13:21,678
and differences there. So

360
00:13:22,705 --> 00:13:24,480
So do you think we've made this any

361
00:13:24,696 --> 00:13:25,891
easier to understand?

362
00:13:27,484 --> 00:13:29,077
I don't know about us. I think some

363
00:13:29,077 --> 00:13:30,192
pictures help. Yeah.

364
00:13:31,802 --> 00:13:32,121
So,

365
00:13:34,196 --> 00:13:34,515
I guess,

366
00:13:35,233 --> 00:13:36,611
I'd almost have to say

367
00:13:37,068 --> 00:13:37,946
if you got questions,

368
00:13:39,078 --> 00:13:41,711
drop them down below. We'll go ahead and

369
00:13:41,711 --> 00:13:43,387
and do our best to answer them and

370
00:13:43,387 --> 00:13:44,504
steer in the right direction.

371
00:13:45,222 --> 00:13:45,722
And

372
00:13:46,593 --> 00:13:48,849
just to circle back to what caused this

373
00:13:50,423 --> 00:13:52,360
topic to come up in the first place

374
00:13:52,658 --> 00:13:53,158
is

375
00:13:54,348 --> 00:13:56,041
someone opened up an electrical

376
00:13:56,655 --> 00:13:57,928
oven that they had,

377
00:13:58,644 --> 00:14:01,032
and it had a ground, an isolated ground

378
00:14:01,032 --> 00:14:02,089
coming from the panel

379
00:14:03,593 --> 00:14:04,389
to the outlet.

380
00:14:05,265 --> 00:14:07,176
And he had some friends that were telling

381
00:14:07,176 --> 00:14:08,711
me he needed to then

382
00:14:09,484 --> 00:14:12,610
put a jumper from that to the electric

383
00:14:12,610 --> 00:14:13,570
box also,

384
00:14:14,690 --> 00:14:15,670
but that's already

385
00:14:16,290 --> 00:14:18,370
already bonded back to the panel. There's no

386
00:14:18,370 --> 00:14:19,810
reason to tie those 2 together.

387
00:14:20,623 --> 00:14:22,136
If there was an electrical shock,

388
00:14:23,171 --> 00:14:25,002
you know, now you no longer have an

389
00:14:25,002 --> 00:14:28,108
isolated ground from your appliance back to the

390
00:14:28,108 --> 00:14:28,426
panel,

391
00:14:29,156 --> 00:14:31,003
because you've bonded it

392
00:14:31,375 --> 00:14:34,308
to the to the, electrical box. So Right.

393
00:14:34,625 --> 00:14:35,655
You don't wanna do that.

394
00:14:36,783 --> 00:14:40,370
So if if you have AA4AA4

395
00:14:40,370 --> 00:14:42,681
conductor outlet, and has a ground, you put

396
00:14:42,681 --> 00:14:44,217
your ground in there that's isolated,

397
00:14:44,850 --> 00:14:45,970
back to the panel here.

398
00:14:48,690 --> 00:14:50,129
So that's where that goes.

399
00:14:51,330 --> 00:14:52,950
And that's what started the whole

400
00:14:53,423 --> 00:14:55,885
the whole topic. We just wanna make sure

401
00:14:55,885 --> 00:14:56,679
nobody gets shocked,

402
00:14:57,314 --> 00:14:59,482
and this is bonding and grounding

403
00:15:00,094 --> 00:15:02,000
are are really important and you need to

404
00:15:02,000 --> 00:15:04,165
make sure that that it's all done correctly.

405
00:15:04,564 --> 00:15:07,116
I wanna say with that, keep it square

406
00:15:07,116 --> 00:15:07,356
level.

407
00:15:08,153 --> 00:15:10,227
Till next time. Till next time. There you

408
00:15:10,227 --> 00:15:11,982
go. Alright. And

409
00:15:12,874 --> 00:15:13,987
Go tokyo shocked.

410
00:15:14,702 --> 00:15:15,338
Don't shark.
