Question

Joists, Acoustic Tiles and Romex - is this OK?


Hi,
I am fixing my basement. I'll be installing acoustic tiles (i.e. hanging ceiling) from the ceiling joists. I'll also be installing receded lights (i.e. cans),type IC. For the lights I was planning to use regular Romex and staple it across the bottoms ( lenght-wise or cross-wise as required) of the ceiling joists, just above the tiles; instead of drilling the joists and passing the wires through the holes. Would this be OK? Or would I be contravening code?

Cables smaller than 3 #8's or 2 #6's must be run thru bored holes or be run on running boards. Drilling the holes is not tough and will provide more protection for the cables.

I usually run electrical half way through the joists (less chance of causing weaknesses in them) and non electrical (ex: data) at the bottom of the joists using hooks.

You can get drill bits made for making these holes and with a decent (not super high end) plug in drill you can make these holes in like 2 seconds per, goes very well. Usually i find it easier to trace where I want the wire to go, then go and make all the holes, then pull the wire after.

Does it have to be on a running board if it's above a suspended ceiling? I thought it didn't.

I believe you are correct. A suspended ceiling is considered protection from physical damage.
