How to connect cooktop to electrical box
I have an electrical box that is recessed inside the wall, and a conduit for the cooktop that needs to be connected, and strapped down. That is 8-gauge wire for a 40a service, so it probably won't fit in one of the holes for normal romex. Do I have to cut open the wall to make this work? See pictures.
Ideally, the electrician should have installed a metal box with conduit holes, and then during install, I would have a box extension with more conduit holes. Right now I think my only option is to cut open the back of the cabinet and the back of the wall and put one of those in.
