Scott, youre getting as good as I used to be at finding strangeness... I can understand a plumber being cool with us and putting a waterline out for us to bond, but I'd think a cap would be favorable to the hosebib on the end... [Linked Image]

at least there's a bib on it to stop the grounded electricity from leaking out...and the handle is green indicating a grounded faucet.

Where in the code DOES it indicate size of water pipe necessary to stick your ground...... Something seems funny here.

A more serious thought, why couldnt the plumber have used a ball valve and pipe plug? That way some poor fool cant flood the place.

Doesn't it strike you as ironic that the "Type 1 Enclosure" label is directly under the hose bib.
NEMA 3 req. comes to mind!!

There's no minimum or maximum pipe size in NEC 250.52(A)(1) nor is there a material specified, only that it be "metallic".

[Linked Image] The clamp thingamajig is pretty creative, too [Linked Image]

Many inspectors in this area won't accept a capped pipe as part of the Grounding Electrode, because it may contain only trapped air. As lame as this thing looks, it might have been done in response to a correction notice.

Can a plumber put a hose bibb indoors with no drain?

I think the plumber did this grounding himself after demo of what that ground was connected to. Or, the electrician should have been a plumber.

And they do this, why??--It's the pipe that conducts electricity; water is actually a rather poor conductor. It conducts enough for the few milliamps it takes to kill someone in a bathroom accident, but not enough to seriously be considered as part of the grounding.

In fact, pure distilled water is actually a reasonably good insulator.
