Direct Line Question



Would it be better to run direct lines spaced somewhat apart through the ceiling joist , or could you run both through the same hole in the ceiling joist?

The reason I ask is because I am running direct lines into a new room in the basement that already has holes drilled in the joist which could accomadate the 2 direct lines.

Thanks in advance

It shouldn't make that much difference, especially if you run each in its own conduit. If it's Romex, you might want to keep them about 6" apart.
Should the Romex be twisted to cancel interference? How many twists per foot? Twisted which way, counter clockwise north of the equator?, or would that just magnify the Coriolis effect ?
