In a nearly new Jaguar dealership, we discovered this while installing some new equipment. The contractor that did this not only forgot to pull the shipping label with his name on it off of the panel can, he put a big logo sticker on the panel cover with his name on it!

I guess he's proud ....

Besides the sloppy wire run it looks like the locknut is missing. Is this rigid or IMC? And why is the wire in front of the cover insert?

I am just a handy home owner, but to me it looks like the piece of rigid is too long to put a lock nut on the outside of the enclosure, and there is no bushing on the end to protect the wires from chafing.

The rigid nipple coming up from the bottom is a 2"X6". It passes completely through the KO, with about 1/2" inside the can before the threads even start! The horizontal nipple has locknuts only on the insides of the cans. There's not a bushing to be found anywhere I've been in the whole building.
The wires across the deadfront were just being held up so I could get a better pic of this glorious work (they were laying across the sharp edge of the nipple).
Any wiring above the T-bar ceiling is a breeze to trace, as there are no blank covers on any of the boxes. [Linked Image]
Yup, it's bad.

well, to say the least, i think i see a green wire comming out of the offending nipple.. my guess is the boxes are bonded together.. i hope...

Good call, I just wanted to add (for general public) that a locknut should be inside and outside the box too so that they could be tightened properly.

Another point we should probably bring up is that any conduit 1-1/4" or larger, &/or containing conductors #4 or larger is required to have a bushing on the end to protect the conductor from the sharp edge.

Also, a rigid conduit nipple as shown is required to have a bushing regardless of its trade size.

I'm just being nit picky here. I have never seen any requirement saying conduits 1-1/4 or larger have to have bushings. Lots of sections refer us to 300-4(f). Conduits containing #4 conductors or larger. The way I see it a 3/4" conduit with 2 #4's requires a bushing. A 2" with 20 #10's does not. Please correct me if I am wrong but having heard the 1-1/4" or larger reference before, I think it is either part of an older code that is not valid anymore or one of those many untruths taken as code because thats how we were taught.

I do agree with the rigid conduit reference.

Nick's right. There was a 1-1/4" rule, but apparently it's gone even by '96.
Yes, it was from previous codes.
