1 the following links are pre fitted to the starter. 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.
