I believe that 110.26(F) Dedicated Equipment Space can be cited here.

Not unlike what's between their ears.

Trapped air??????????????????????????????

What the *&#@?

You got to be kidding us, please tell us your kidding.

Where does the NEC say anything about the presence or non presence of water?

I am dumbfounded.

Do they also require metal objects that are bonded, such as outlet boxes, metal conduit, gas piping to be filled with water?

And isn't the sharp "j-hook" bend in the grounding conductor a violation? One, exceeding the bend radius of the conductor and two, IIRC there is a specific reference to not having any sharp bends in the grounding conductor.

The hose bib was installed to put out the fire from the Challenger switchgear.

Guys, This "air pipe" business come up with various inspectors in various jurisdictions in the area.
These have not been just new-hire-wet-behind the-ears combination inspectors either, but have been seasoned veteran electrical inspectors.
My only guess, and it's just that and nothing more, is that the subject came up at an IAEI meeting and this was the concensus.

I still can't figure for the life of me though, why the inspector (or any of you guys) didn't notice the perverse use of the clamp(s)


If you'll look at that ground clamp you'll see that the actual conductor is clamped by nothing more than the saddle that is meant to hold the armor on a piece of armored ground wire. That clamp was never meant for this type of use, and has a maximum of a #6 conductor, as does the "hub" portion.
The correct hub, if used, would have a 2 screw clamp right in front of the hole that that conductor comes out, and the armored clamp could be saved to be used where it belongs.

One more thing: the red cap looks like the socket-protector that comes in recessed lights.
