I have a service panel that is the usual setup, mounted between two studs. The studs are not load bearing. I want to bring NM (Romex) cable into the side of the panel, but that involves drilling through the studs. How do I protect the cable?
Would this work, using a rigid conduit nipple then clamped by conduit nuts? (I might have to add washers or shim on the outside in case I can't get the threading just right).
