Assume that I have 5 circuits, all using 12/2 wire and and each supplying
various plugs and switches throughout a workshop. I drill a hole through all
the studs in order to get the wire to the respective terminals. Can I just
drill one hole in each stud and thread 5 12/2 cables through it, or do I
have to drill 5 holes, making swiss cheese out of them? I guess I'm
concerned about what amount of heat 5 cables running together would
Short answer. No. Long answer. You're right, heat and them
moving around each other because they will never have equal load
and expansion will be different They have been known to actually
rub each other bare in a tight hole. That's the old romex though,
the new plastic probably would not.
However, drill your holes above one another in the center of the
stud a few inches apart and the stud will not be affected at all
Can you provide one reference to this ever happening? Sounds like urban
legend to me. There is no problem running multiple Romex cables through
the same hole in a stud. You can even run Romex through a conduit.
Hey no problem with me. Do that in KC MO though and the inspector
will not pass it until you tear it out. Course he was an ass hole
too. He once made my electrician add a plug because although it
was the 12' apart code called for, there was a 4 inch boxout over
a drain on the wall and he measured around it, ie 4" out and 4"
back and that made the plug over the allowance by 8". You can
only put one wire in a romex connector into the box too or you
tear it out. Been there and done that.
