I am wiring a plug for a Miller 212 230 volt welder. 8 ga. Wire with a 50 amp double pole breaker. My meter shows 120 volts on each hot terminal and the ground is good. Nothing happens when I plug the welder in. I hooked my 230 volt compressor to this receptacle and show 120 volts at each point in the compressor switch, but again, nothing happens. Thoughts.
