Hey folks, I can’t seem to find anything in the NEC about how many cables may be pulled through a single bored hole in a framing member (I know the edge of the hole must not be closer than 1.25” from any edge without a steel plate). Does such a regulation exist for residential wiring? If so, does it go by the number of cables or the total of the conductors? Also, is there a rule limiting the number of cables which may be run vertically through a single 14.5” stud bay? (Again cables or conductor total?) Any problem with interference from induction/EM fields? (I know, I know; I’m getting paranoid with that one.) Thanks in advance...

Can the light switch for the closet lighting be located inside of the closet or does it need to be on the outside? I have several closets that are around 3ft by 3 ft that I want to install lighting in and would prefer to have the switch on the inside. I am familiar with the rules on what type of lighting and where I may install it in the closet. Thank you for your help. -Bill
