I'd like to add an outlet behind an existing outlet in the same wall (back-to-back). Actually, the new outlet box can't be directly behind the existing outlet box since there is not enough depth in the wall, but on the opposite side of the stud might work.
I can do the electrical work no problem, but I don't want to knock a bigger hole than necessary in the drywall. Has anyone done something like this, have any advice or cautions against possible problems I may encounter?
Thansk in advance.
