I'm not sure if that top black is a conductor, or a uncut ty-wrap.. I think it's the latter. In fact it looks as though we might be seeing the uncut ends from two - one on the bundle of red wires above and one from a bundle on the right. P.S. The phase colors have been bugging me, and thinking about it some more I seem to recall our esteemed Webmaster telling us once that red-black-blue ordering is also common in Long Island. Bill, are you out there? Am I imagining things? [This message has been edited by pauluk (edited 06-29-2005).]

Are some of the conductors passing from the vertical conduit(s) through the first panel, and into the second one?
Perhaps even passing through to somewhere else? Would this be forbidden?

Wouldn't that cause a field around the conduits, cause them to chatter and fluctuate, and then turn cherry red hot?

My guess is that there probably is a wireway above these panels. Not only would you have the violation(s) you can see here, but the wireway above would probably have more than 100 conductors in a cross-section, not derated. This is a "pet peeve" of mine, and I see it too often. "Elektrition" will put as many 3/4" or 1" conduits across the top of the panel as will fit, so they don't have to figure anything out. (Note the empty conduits)

I've seen empty conduits before, at a new construction at my university. My electrical teacher said that it's fine to do that, plus easier on the rough-in, and have them meet at a junction box, just in case you'll even need to pull a new circuit to a new location.

On a recent walk-thru I noticed the EC didn’t run separate hot, neutrals, and grounds for circuits that I indicated on my drawings. I told the EC he needed to go back and add dedicated neutrals and grounds for the circuits indicated. This was his solution. I questioned them about the code violation, said they never heard of that in the code. By the way, this was the owner of the company and his lead foreman. Craig Lusinger

I'd like to see the Code reference for the "dedicated neutrals" myself. Isn't "dedicated neutral" an oxymoron? If the grounded conductor is a dedicated one, then it's not a neutral, is it?
Nonetheless, if it was on the drawings, and part of the contract documents, they should have done the job per specifications.
