Which box for flush-mount (in-wall) outdoor electrical outlet?
I'm adding an electrical outlet by running cable from an inside outlet in the same cavity. I will have a GFCI outlet inside, and run a regular grounded outlet off of it to the outside (as I've seen suggested here).
My question is about receptacle boxes: I know I can use a bell box, mounted to the surface, and then a waterproof cover. But which box would I use if I want to cut a hole in the siding and mount in the wall? Can I use the regular indoor old work boxes, or is there a special outdoor version? I haven't seen anything at the home improvement stores that mounts inside the wall and is specifically for outdoor use.
