Possible Cause: Power supply stopped / Breaker switch off. Plug another appliance into the outlet to see if power is present. Reset circuit breaker to on position and push power button on user interface and hold for at least 1 second. Always use a dedicated, properly grounded circuit.
Why does my motor keep Tripping the circuit breaker?
When a single phase induction motor is at rest, the circuit is open and the motor requires no current. However, when the circuit is closed, the motor draws a tremendous inrush current, as much as 6 to 8 times its running current, which can cause the circuit breaker to trip immediately.
What happens when a circuit breaker is closed?
When the circuit is closed, the motor starts drawing a tremendous inrush current, which is up to 6 to 8 times its running current. This large inrush current can cause immediate tripping of the circuit breaker.
