Thinking of expanding a 2-gang box to a 3-gang box in a bedroom (light switches next to the door). I'm measuring about 6.25" between the studs. I want to use the following box, which is listed as having a width of 6.02".
It would be attached to the right stud. The left stud has a wire running down it, 12-2 Romex, that is taut and stapled to the stud. Seemingly, based on the measurements, there would be enough room for the box to fit in this space, even with the wire, and it wouldn't be squeezing the wire. Is there a reason this wouldn't be allowed provided the wire is not getting compressed?
