Should/can I run the 12/3 wire inside the wall or just run a conduit up to the attic?
I want to install split receptacle 20 amp outlets in my garage. The subpanel in the garage is surface mounted to a finished and insulated wall. The other walls in the garage are not finished. So my plan is to run the wire up to the attic and then feed it through the unfinished walls to the outlets.
