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.
Keep the new outlet between the same two studs as the old, or else you'll
probably be making a bigger hole to get a drill in to drill thru the stud.
The old-work box Bob mentions has 'wings' that fan out behind the drywall
and a screw draws them tight against the back to hold the box in place.
In the good old days of metal boxes we used plaster ears, small pieces of
sheet-metal shaped like an upside down "F" that slipped between the box and
the paster. The 'arms' of the "F" were bent over inside the box to hold it
Easiest electrical trick in the world. Put it on the same side of the stud
as the existing outlet and buy a old work (existing sheetrock) box at home
depot or lowes. Make sure you measure the size and color of the finish
plate on other outlets in the room so they match.
Normal and common. An old work box just to the side of the existing
box, not on the stud side, works fine. I usually break out a tab in
the existing box on the side away from the sud, angle a long
screwdriver through it and pop a hole in the opposite wallboard with a
hammer to locate the new box.
