Is it a violation to bring a raceway into the side of an outdoor disc. above the fuses? If it is I can't find it, and have never been failed for doing it. [Linked Image]

It should be fine if you are using sealing locknuts to maintain the integrity of the NEMA 3R enclosure rating.

Yes I agree. Had a little disagreement with a coworker regarding this. He claims it is the reason manufactuers don't supply KO's in this location.

Hey Rabbit, I agree with Ryan with a foot note. Some manufacturers will leave you hanging due to their listing info regardless of the entrance fittings.

I have never been tagged for this.

How was the antique tractor show? I ended up working on a MG set that weekend and the next. [Linked Image]

I think the "thats why theres no KO's" is a pretty cheesy argument.

What about a typical indoor 42 circuit can that has no KO's? Does he say that you can't punch it out? Of course you can.

Ryan J. , I have never heard of a sealing locknut. Could you reference a code article and maybe a link to a picture of one? Also are these required for type 3R enclosures?

Hey Roger,

Danged if I know I wound up working too. I had built a service for a manufacturd building (spelled double-wide) and when the AHJ came to look at my service he wouldn't accept the NM inside. This is being used for a pharmacy. The owner freaked and I wound up Jerking MC all day Saturday. There's always next year.

I'm looking for the code right now....I think 110.3(B) might apply, but there is an article that states something to the efect of "equipment shall be deemed suitable for the enviroment in which it is installed", and I beleive there is somewhere else, but I'm struggling to find it! Help please?
