Thanks for your electrical question Tobi.
Electrical Wiring for Single Phase Motor Controls
Tobi, a motor control is simply a relay contactor that acts as a switch which is activated by a different power source or a control circuit. The control circuit may be operated manually, or automatically when the control circuit is wired through sensors or other control devices. The single phase contactor is sized according to the electric motor voltage and amperage, and the control circuit is designed for the specific type of devices that will be used to control the single phase motor. The control circuit is typically a lower voltage than the motor voltage.
