I was a little disappointed to see that NEC 358.24 only says that bends "be made so that the tubing is not damaged." I suppose, though, that the further specification that the radius "shall not be less..." could apply to finding a violation to the sort of free-hand bending as is shown in this photo.

Why spend $8 for a bender, when you can tweak the pipe between studs, bricks, or a handy bumper? :-(

Reno,
I do think the tubing is damaged.
Aah, maybe I'm just picky [Linked Image]

Does it make the electrical installation unsafe if the tubing remains undamaged?

No Ryan, but if I installed the pipe in the pic, I would certainly hope nobody ever found out who did it.

I think this might fail the "workman-like" test. I confess that I've improved the angle of a conduit over my knee several degrees occasionally when deep in an attic or crawl-space.

I suspect that one of the bends made is too small in radius to comply with code...and the EMT almost certainly has a "flat spot-" even if this guy stopped just short of a kink.

With workmanship like this, no one should be surprised to see that the EMT is completely unsupported, or to find #12 wires serving a 30 amp water heater (yes, he did that also.) And, of course, no ground wire- even though there is flex used.

That sounds OK... if he used 2 per leg [Linked Image]

Of course, about the grounding wire... if the flex is under 6', is is required?

Good catch, Doug....that is one of our local requirements: all flex, sealtite get a ground wire.

WM, 110.12 issue there too. Looks like a 90 with 2 kicks, a twist, and a curl. Unbelievable.
