If a condenser fan motor grounds out, it will usually what?

When a condenser fan motor grounds out, a path to ground is created through a damaged winding or insulation, which effectively becomes a short circuit. That short pulls a large surge of current, far above normal running current. Protective devices in the electrical system are designed to detect this abnormal surge and trip the circuit breaker to shut off the power, preventing damage to the motor, wiring, or surrounding equipment. So in a grounding-out scenario, the unit will usually stop because the breaker trips. The other options don’t fit because grounding out doesn’t cause the motor to run faster, nor to operate with less current, and protection would prevent continuous operation.
