Conduit into DL

[mstrlucky74]

Any reason you can’t run EMT/RGS directly into the housing/j-box that’s attached to a downlight? Thanks.

Yes....several

Code wise no. But it might be impracticable to do it that way.

 

[mstrlucky74]

Yes....several

Which are? So if spec called for all wiring to be in EMT or RGS woould one still be able to provide a whip to the fixture? I assume, according to what you are saying, that would be the practical way to do it?

If you were in Chicago that would be the only way to do it. But providing a whip makes the installation much easier as well as allowing repositioning if needed.

So attached is the downlight I’m referring to and the layout on the drawing. You could not pipe right into the housing?

Yes you could.

There are reasons that running EMT in to the fixture would be impractical or more difficult, but nothing in code that prevents it, and in some cases codes that prevent them being flexed to. AHCA in Florida was not allowing it in hospitals for a while but I think they have come around. When the ceiling is hard lid and MC isn't allowed, I expect my guys to run conduit not flex.

NC DHSR and some local NC inspectors tried to require the same thing based on 517.30(C)(3), the problem was 517.30(C)(3)(3)d, the requirements of IBC chapter 7, and CISCA (grid ceiling installation in seismic categories) which basically says it is necessary to have a flexible connection to items attached to the ceiling grid.

Bingo....now the OP needs to find out if MC is allowed or not

Hard lid?

MC is not allowed but like I asked since that's the case would "whips/tails" still be allowed even though it asked for full conduit?

Sounds like you need to submit an RFI. in NYC you could use mc/bx/ or fmc but your spec might not allow it basically your allowed to by code, but the spec is what your going off of

I understand. But curious if you has spec that read like mine(full EMT) would fixture tails(FMC) be accepted. I know yes by code.

Full emt to me means full emt. RFI is your friend here

Is FMC listed in your spec? If so, what are uses permitted for FMC?

Did you look in the lighting section of your spec?

But if you use 4 sq boxes with whips and it is a sheetrock ceiling, then access panels must be provided for the 4 sq boxes.
