ic rated can lights

[joshgarcia]

This should be an easy one, just unsure. i know that an ic rated can light can have insulation around it and non-ic cannot, but my question is in a basement ceiling do the can lights need to be ic rated if there is no insulation but the joist depth is just enough to fit the can light? Or can you use non-ic if there is no insulation? thanks

I think you have to have 3" clearance on non ic rated.

 

[joshgarcia]

but no clearance needed on ic rated?

Non IC needs ?" clearance from combustable materials.

See 410.66 (A)(1) in '05 NEC.

Correct - 410.66 (A)(2) in the '05 NEC

I googled it an 1 manufacturer says 3" so I think you have to follow installation instructions

which mfg???

 

[cpal]

2008 410.116(A)(1) Non-Type IC or the old 410.66

Unless a isting or instruction says different the Code states 1/2" from combustible materials

http://www.caprilighting.com/techtopic/capri/10.pdf and I think I had this arguement with the ahj on halo non ics he wanted them 3"

If there is no insulation then you can use non-IC cans. If there is insulation then you need to follow the manufacturer's instructions. All of the ones that I've seen usually require 3" of space from the insulation as per the manufacturer's note.

That manufacturer spec is for non-IC where there is insulation. It makes no mention of a 3" clearance from combustible surfaces. I say ?" is good to go.

Lightolier requires 3" for non-IC cans, look at features #6:

I actually just pulled that off the net and saw 3" didnt read with insulation.
I had a situation and I do think it was halo not swearing to it that non ic wanted 3" reguardless of insulation.

Rob,

That too is distance to keep insulation away. We are talking about combustible materials. 410.66(A)(2) '05 NEC 410.116(A)(1) '08 NEC

I'm not saying I doubt you, but I have never seen that type of spec. I would think a ?" air space around a fixture is more than enough clearance to prevent combustible material from ignition.

Actually my memory is sooo bad there could of been insulation and thus the 3". I know you are right about the half inch from combustable material if the instructions allow it.

So!
we are all on the same page? Non IC mo Insulation, 1/2" should be good to go!!

yes / no???

OP was not asking about insulation just tight to the structure.
