Code question (NEC 300.4)


I'm asking the following question after looking up NEC article 300.4(D)...

Are there any issues with running NMD wiring through a wall made of 2x3 studs and plates? This is an existing wall in a 1957 house. The wall is plaster on sand coat on 3/8" gypsum board lath. Presently, one side of the wall is removed and the other remains intact. I'm planning on boring holes for NMD 14-2 wiring allowing a min clearance of 1 1/4" from the inside edge of the intact wall to the hole edge. On the opened side of the wall, I'm planning on protecting the cables with metal plates wherever the wires go through framing. I'm concerned about NEC article 300.4(D) "Cables and Raceways Parallel to Framing Members and Furring Strips" because the cables running vertically along the studs would be stapled at a distance of less than 1 1/4" from the edge of the 2x3s. So to conform to 300.4... would I need to offset the cables 1 1/4" from the studs?

Also, I don't see any but... just in case... are there any issues with fishing cable through 2x3 stud walls that have not been opened up?

Since it is so hard to get information on CEC I'm asking about NEC rules but if someone knows about CEC (Quebec) then so much the better.

Thank you.

The NEC is meaningless in your case. Please wait for one of our Canadian friends to reply.


Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
