We have a lowered ceiling in the kitchen and I am currently raising it. By doing so, I am having to re-route some of the wiring. I have drilled 1 1/4 in. holes through some of the rafters and fed 5 wires through the whole. My question is if this is ok. I was told by someone before that there was a limit as to how many wires could run through a conduit, but was unsure if 5 wires bunched next to each other in this fashion was exceptable.
