I realize it's common practice for electricians to install a bonding conductor in EMT but is this a requirement?
What are contractors doing across the country?

Here are a few rules pertaining to this....
10 804 (D)
10 808 (4) refers to section 12 1400 to 1410

Thanks!

I've never put it in any pipe without it but that's above code. Can't always trust those set screws to be tight.

But you can always trust a wire termination?

No but atleast I have a backup if either bond fails

EMt in a ground slab must have a bond wire installed outdoors where subject to mech damage
see 10-804(d)

When you do a non-metalic cable job do you add a second EGC in case the one in side the cable fails?

I am not picking on you I just find it funny that many electricians seem to trust their ability to splice more than their ability to properly secure a pipe and tighten the fittings.

Sometimes I run a wire EGC, sometimes I do not.

No I don't :laughing: but I get where you are coming from. Usually it isn't much extra work to pull a bond. It's just like when companies want a bond wire in cable tray. Not required but everyone wants one.

It's not much extra work to pull all #10 wire for 20A circuits either.

But in both cases, it is useless.

I've seen plenty of splice boxes in which people have been working in them for years and conductors pulled out of splices. It's usually easy to tell when a hot or neutral pulls out because something doesn't work. But when a ground pulls out no one knows. I trust the pipe as an EGC more than a splice.

 

[BlackHowling]

Everyone gets that splices can come undone and that set screws can get loose. The OP just wanted to know what electricians are doing across the country is all. In my experience it has been to always pull a bond unless it's low voltage. Hack and BBQ may not pull them and you guys have your reasons. Both ways are legal, mine can just be a little more pricey and time consuming.

In some cases I might not pull a bond i.e existing pipe that is pretty full/short runs/rigid conduit. I just haven't had those situations occur yet.

 

[macmikeman]

Here is how I decide. I look in the back of my van. If there is a spool of #12 green, I use it. If there is not a spool of #12 green in there, I confidently convince myself that we did it for years without ever once pulling in a ground and it was ok then so it is ok now.. no ground.

If I think the emt could be subject to damage, or the building could shift, or there could be extreme temperature changes I make sure to pull a bond.

Other than that I am hit and miss and there is no logic behind when I do it and when I don't.
Right now I have a roll of stranded 14 green that was an ordering mistake and I hate it. I have been pulling it in every chance I get.

If you really think the EMT can be damaged to the point it's electrical continuity would be broken you should not be running EMT in that area.

Im a maint elec, a grnd is a savior to pull in extras so i always pull it, material doesnt much matter where i work and i got time when installing new, so always a grnd and if its control or far pull, usually gets extra conductors... ##14,12 and 10s that is!

Just keep in mind the 2014 NEC will require the spares to be counted as current carrying conductors for the purposes of derating.

I don't understand why this is such a hard thing for people to grasp.

Listen, I am starting to get pissed off, scared if you will, that we are agreeing a lot lately.


Global warming is real! GO!

People get it but idiots can damage anything given the right conditions :laughing:

 

[drspec]

I always pull a ground wire in EMT, but that's because I came up doing residential and no matter how hard I try, I CAN NOT NOT have a ground wire in my runs.

I know code doesn't require it, but that's the way I am

 

[BBQ]

Than run threaded conduit.

Because what you are saying is that you are fine with raceway damage as long as there is a wire EGC in the pipe.

I've already told you that I am not against global warming and only dropped that into threads to troll, just like abortions and Energizer bunnies. Wait, that last one wasn't me :whistling2:
