Panel as Raceway. Yes or no.

[frizbeedog]

A circuit exits a panel.

It enters a junction box adjacent to the panel. (behind the panel actually, on the other side of the wall).

It gets routed through a contactor.

It re-enters the panel and then exits the panel through a conduit, and out to the load.

I ask because I saw this last week and am looking for code refrences, for or against. Or similar examples.

Here's a picture of the install. You may notice it from a thread I did last week.

It's perfectly legal, see 312.8

The picture is not really relevant to the question though.

Thanks roger. for the code reference.

The picture is not relevant to the question?

...it was, I thought, to represent whether or not that install was a violation.

An opinoin was given to me that this was a violation, from a co-worker, as an example of it being used as a raceway, and I wanted to clear it up.

...any violations regarding the installation as I described?

edit.
The picture just shows where the conductors are routed through before re-entering the panel, and then exiting it again. I see where you might be confused as to it's relevence.

The reason I said the picture is not relevant to the question is, it wouldn't matter what would be feeding in and out of the panel, substitute a photo cell for the contactors for instance, in either case it is a legal installation if 312.8 (splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space) is not violated.

I gotcha now.

Somehow I knew it was right. Thanks.

You're welcome.

That looks like a perfectly acceptable way to add contactors for appliances or blowers for a fire-suppression hood system to me. I'm going to be adding three to a system on Monday.

Added: I probably would have used a single box for both contactors, though.

The 'other' electrician didn't know what we was doing. He ran two conduits directly into the microswitch box of the suppression head; no J-box. Nothing works correctly. He was quickly fired.

That's exactly what I have to do. Add one for the deep fryer. :smile:
