When I was building my house, I installed an outlet under my service panel which was temporarily connected to a breaker in order to supply our tools while building. I have since removed the outlet but now I need an outlet there again. Since the panel is in the basement, behind hinged wooden panels, is there a conflict with the code if I install a receptacle in that location under the service panel? I could locate a nearby circuit which has less than 12 units on it and wire it into that circuit. Or could I wire it directly to another circuit breaker in the panel? Is a 15A circuit breaker allowed to have two wires connected to it? thanks for the advice.
