Say I have a 10 Horsepower motor on a planer and a rotary phase converter. The single phase power to the rotary phase converter is rated at and cabled to handle 100 amps.
Everytime you try to start the motor, it somewhat comes up to speed and then it trips the 100 amp breaker. If you take the belts off the motor starts fine. The planer head spins freely. If you put the belts on to the head it trips the breaker.
Checking the wiring it was a single phase leg, manufactured leg, and a single phase leg.
Switching it around so that the single phase legs come first and the manufactured leg comes last makes it work properly.
So I assume the single phase legs have to come first, but why? If there were true 3 phase power from the power company I don't think this would be an issue would it?
Do the single phase legs have to come first and the manufactured leg to come last in order for the motor to reach full power? Why?
