I have an unfinished ceiling in my basement that I am currently prepping for a Ceiling Max type ceiling. I have a run of old woven jacket wiring that goes from the breaker box to the kitchen, but is stapled underneath the joists. I also have a run of BX that follows the same path, but is run perpendicular through the middle of the joists. I am planning on replacing the old woven jacket wiring with NM, but would like to run this through the bored holes that the BX currently goes through. Is it a code violation to run a NM cable and BX cable through the same hole(s) in joists?
