I have an old Gardner Denver, 2 hp compressor. The old 2 hp GE motor burned up, and I ordered a new motor from Surplus Center. The motor is hooked up 230 vt's, and has a diagram for either 120 or 230. I put white to L1, and black to L2, and green to ground. It seems pretty straight foreward to me. On initial start up, it kicked the two 30 amp breakers in the panel, as soon as the motor got wound up, this happened 3 times, so I switched the wires in the panel, over to a set of 40 amp breakers. The same thing happened again repetedly. Thinking that the motor was trying to do more than it was designed for, I removed the belt (load), and started it up, It then kicked off the thermal overload, shortly after starting. Is this a bad New motor?, or is it my wiring job? I don't have a free electrician available! The same wiring used to run the old motor ok, till the mice got into the motor.
