I'm putting in a couple of new electrical circuits in a new room. What is the accepted practice when you are running two cables in the same direction? I have drilled a hole in the studs to run one cable, but with a 3/4 inch hole, I can fit two cables in the same hole. Is this the right way to go, or is the norm to drill another hole a few inches up and run the second cable separately?
Same question with respect to stapling cables coming in and out of the boxes. Is it the norm to staple each cable separately to the stud, or to secure wires running in the same direction from the box with a single staple?
