Canadian Electrical Code Question

flemingetq

I am unable to find the Code number of the Canadian Electrical Code for the following install.

Why do the holes have to be drilled in the center of the 3.5inch wood stud. I need the Code Rule Number. I know why it has to be done, just do not know the code number.

Also are there any electrician in here from the Peterborough, Oshawa Ontario Canada area who would be looking for an apprentances starting in March 2011.
Thank you for all your help.

Sorry I can't help you more specifically, but I can tell you I'm pretty sure that any such requirement would be in the building codes, not the electrical codes.

12-516 (a) Cables must be 32mm from the face of the stud.

That would mean drill the hole in the center.

Needs to be done to reduce the likelihood of screws/nails from piercing the cable and may help in not reducing the load bearing capacity of the wood member (although I imagine this is a minimal benefit).

Same as the US. The largest drill bit you can use is 3/4" or 19mm provided you drill exactly in the middle. I've been using a 5/8" for my wiring because I can get two 12/2 NM cable through it if needed.
