Question 1
There are a number of individuals where I work who insist that no more than 3 NM cables can be passed through a bored hole in wood studs.
As far as I have researched, there are no NEC requirements for this.
1. Does anyone know of a section in the NEC that I may have missed, that requires this?
2. Does anyone else run across this same situation?
Question 2
Also have individuals in this area that do not permit data cable such as Cat 3 & Cat 5 in the same bored hole as NM or AC cable.
1. Where are those requirements found in the NEC?
Question 3
CATV cable does have a 2 inch separation requirement from NM Cable as per 820.52(A)(2) ['02], 820.133(A)(2) ['05].
1. Does this tell me that CATV type cable cannot be installed through the same bored hole as NM Cable?
