Limit to wires thru single hole in stud?
I've never heard this before but didn't want to do something wrong from a code standpoint. I was running extra wires to a breaker box before drywalling around it. I noticed that there is swiss cheese above the breaker box with no more than 2 wires per hole. I've never heard that as a rule and I found one hole somewhere else that had 3 wires - but then I though that maybe I did that or it was a mistake.
So is there a maximum number of wires that can go through a single hole in a stud? I have 4 and with the swiss cheese and existing wires, it is hard to drill an extra hole.
