test electrical junction box You need to kill all power to the electrical circuits in the box and using you continuity tester to "ring out" which hot wire is going to ground at the box. That being said, replacing the metal box with a plastic does not fix the problem of a shorting circuit. It looks to me like the inner knockout is 1 3/4" wide, which is what you need for an 1 1/4" trade size connector.
