Just like electric motors, an electrical service panel should be equipped with a label which is attached either on the cover or inside the door.To stay on track with this question, the shop where the motor is to be installed must have an electrical service which supplies either 3 phase 230 volts, or 3 phase 460 volts. The information found on the label tells all about the motor size and electrical requirements. Every motor should have a name plate which is typically attached on the side or end of the motor.The Basic Requirements for Wiring Electric Motors Wiring a 3 Phase Motor for an Air Compressor Thanks for your electrical wiring question Cody. This electrical wiring question came from Cody in Enid, Oklahoma. When the compressor was moved it was simply unplugged from the wall and moved, all pressure switches and motor wires are in their same locations as before.Is it possible to wire the compressor with this combination of wires and where do they go?.The wires from our shop circuit breaker has 2 yellow hot wires at 120 volts each, 1 white neutral wire and 1 green ground wire. The motor starter is a Cutler Hammer # A10CNO.It is all wired and hooked up to the controller, but here is where we are having problems, we cant get it to start, it only hums. The label shows that it can be wired for 220 or 460.
The motor is 3 phase and it appears to be wired according to the diagram for the low voltage 220.It ran fine at the previous shop and then we moved it to this shop.We have a Saylor Beall air compressor we are trying to get wired up.Electrical Question: How is a 3 phase air compressor wired and where do the wires go?
