I am in the process of adding an outlet to a wall in a previously renovated basement. The wall is drywall, mounted to furring strips which are attached to the cement wall.
My two options as I see it are:
- Externally mounted box run horizontally like wiremold or EMT and a handybox, or
- Cut a hole in the drywall, mount a handy box directly to the cement. Fish NM down vertically between the drywall and cement wall into the handybox. It leaves about 3/4" of the box jutting out from the wall. Patch around it, paint, good to go.
Which would be more "proper"? Any code concerns?
