Water Pipe Ground Wire

[texie]

Is there a special fitting for terminations that bonds the armor to the bare copper conductor?

Cheers, Wayne

Yes. there are clamps for this. Armored GEC is not a thing in my neck of the woods but I know it is in CA for some reason.

Congratulations on your 43 years. For the sake of the trades, I hope that we can attract some younger individuals and generate the interest in gathering and training that I experienced in my 40 years in the trade as well.

And congratulations to you. I know some areas, NC for one is trying to bring young people in, and be it good or bad, they even softened their requirements for licensing. BTW, welcome to the forums.

The pipe clamps have a mechanism to connect both the armor and the solid conductor to the pipe.

How about the other end? Suppose you want to connect it to a bare unarmored GEC, or have it enter an enclosure. How do you bond the armor at that end?

Just use the same clamp without the pipe.

You don't need to, as they're in contact for the entire length, but you can use a cable clamp at an enclosure.

250.64(E) makes no mention of cable armor, just raceways and enclosures.

Not sure texie, but I'm sure the inspectors out here have a pretty good reason ..

Entering the panel, I just use a romex connector with a ground bushing as a lock nut to bond at entry then end at the ground bar, seems pretty straight forward ..

The only real inspector is one that has coveralls in their trunk and uses them for inspection in the attic or under the house.

I got flagged for using #4 THHN wire for the water pipe bond back to the service panel, said if thhn was used, it had to be in conduit. Anyone else run into this for a ground wire?

Is there a need to protect from damage? That then would need conduit (one option).

One AHJ I worked in required all GECs that were accessible from the street to be in conduit or armor. It was a local amendment and the reason for it was copper theft. GECs were going missing for a while in some neighborhoods. Unless there's a local amendment like that, then the OPs inspector is just wrong.
