Can you support exit signs like this?

[cppoly]

I see this all the time where an exit sign's last support is at a ceiling mounted junction box. EMT is not supported either.

Is this allowed?

I hope it's okay. I have hung lights that way.

Thanks.

It's strange because I see this all the time at Costco and Whole Foods.

That's not emt hanging down

Agree, IMC, or rigid. Have seen signs hung from a couple of pieces of jack chain, supplied by MC strapped to one of the chains, since most MC has solid conductors, doubt it's kosher.

If mc is secured to the jack chain as well it could be stable enough. 1/4 inch rod instead of chain and then its 100% good to go.

But it is not permitted to use solid conductors to supply chain supported lighting fixtures, has to be stranded.

That's a good idea. Do you have a code reference?

410.54(E)

410.54(E)

I thought that was for zip cord that's part of a fixture construction but if applied to this type of install then good to know.

without looking at the code referance, I think I would agree that the MC is a wiring method not fixture wiring

Did they drill a hole in the 4 square box cover for the fitting? Or do they make box cover plates with knock outs?

I think it would be more secure if they rotated the box 90 degrees and use a side knock out. Plus you would still be able to take the cover off without taking the exit sign down.

They also make a fixture swivel cover

That reference is not about fixture wiring.

 

[suemarkp]

Its not? The section it is in says "Wiring of Luminare's" and the things in it seems to be things that a manufacturer of a luminare would need to follow. And I think the code reference is 410.56(E). It does seem like a good idea though to use stranded on a chain supporting a fixture.

Is an "exit sign" a luminaire covered by art 410 or is it a sign covered by art 600?

I did a little looking and haven't found anything yet in either article that mentions exit signs.

They seam more like an electrical device like a faceless GFI or 120v smoke alarm.

Maybe the question is what are they listed as?
