Hey guys im new to this site. But here is my question. I am running sheathed electrical cable threw the ceiling to attach the recessed lights and also to attach to the circuit breaker. Its the easiest way i can do it. The question is can I run more than 1 cable per hole? I am using a 1in bit and the hole is big enough to run 2 cables with room to spare. I don't want to have to drill a ton of holes in the joists.

Yes, you can run more than one wire through a 1" hole. Any more than three you might start peeling the outer insulation off. Just make sure that when you drill your holes you stay in the center of the joists.

Thanks for the info guys. I try to keep as few holes as possible but i found if i drill a 1 inch hole i can run 2 or 3 cables versus 2 or 3 small cables. These are old 2x8 beams, im not to worried about them loosing support. The only one i had to place the whole lower than center was on a 4x8 beam as the other side is concret. But I reinforced the area with some wood to compensate it.

Thanks for the help guys!
