Well, after finding out what caused my small outlet fire, I thought that I would examine the other 220 volt outlet that the electrician installed. There were four wires coming into the outlet from the breaker box. Two hot wires, a neutral and a bare ground wire. The outlet was for a three wire hookup. The two hot wires were each hooked up correctly, but the neutral and bare ground wires were both wired together in the outlet box. It has been a long time since I wired anything, but I always thought that you never connected a neutral wire to the bare ground wire in 220v. Should the neutral wire be stubbed off in the outlet box and only the bare wire be connected to the outlet? More problems?
