This is work done by one of our crews. Their work is generally good, but there's an obvious violation. Can you do better than the local inspectors and spot it? (not the workspace violation)






The guys have never been called on it, so stopping the "habit" won't happen until there's another option (Screaming and yelling would get me nowhere, I'd like to offer something positive).

Does anyone have any ideas? How would you make it better and Code compliant??

Electure,
Are you concerned with gutter fill and derating?

How close are those transformers to the wall? Do they have a vent opening on the 'back'?

What's with the apparantly unsupported pipe...was it placed there as a spacer, and then forgotten?

pic1 - behind the xformers

pic2 - a little more obvious... just behind the xformer - 8 blocks up from the c-strut.

In the transformers, do the conductors go under the core to the lugs, over the core to the lugs, or are the lugs facing the wall?

Just a wild guess here.. but are the top breakers in the bigger panels too high up from the floor?

Scott you got me stumped.

I thought of labels but I think I see some.

I thought of the transformers in the working space but they are too high for that.

I thought of protection from physical damage but that is a subjective article and if the AHJ does not think these are subject to damage then it is OK.

So what is it?

Pretty nice looking parallel pipe work.

Bob

Trough above the panels??

Those 2 seal offs going into that 1 panel must be some expensive.

Is it a car shop, looks like a transmission jack??

I must agree with TXSparky on the gutter fill. Thats all I can really see.

Wow!
Yes, it's the derating in the wireway. Everything else is ok. (The C/B's aren't above 6'7", the sealoffs are all poured, xfrmrs have plenty of clearance, lugs are on front bottom. I don't see any unsupported pipe)
The wires in that wireway should be derated to 35%. Most of those panelboards are 42 circuits, and the number of conductors in a cross-section greatly exceeds 40. 310-15(b)(2)(a).


Can you think of another way that this could be done and have it come out clean and still comply??


(And yes, it's an auto service garage)...S
