In the above one phase motor wiring i first connect a 2 pole circuit breaker and after that i connect the supply to motor starter and then i do cont actor coil wiring with Normally Close push button switch and Normally Open push button switch and in last i do connection between capacitor start motor and contactor. Thermal contacts TB white M 1 Z2 - Yellow Z1 - Blue U2 - Black U1 - Red Bridge L1 and L2 if speed controller SC is not required Anti-Clockwise Clockwise These diagrams are current at the time of publication check the wiring diagram supplied with the motor. Use the legend to understand what each symbol on the circuit means.
To read it identify the circuit in question and starting at its power source follow it to ground.
Wiring diagrams sometimes called main or construction diagrams show the actual connection points for the wires to the components and terminals of the controller. Draw a diagram showing how this could be done for a single-phase electric motor using two starter contacts. Always use wiring diagram supplied on motor nameplate. Here are ten simple electric circuits commonly found around the home.
