Lock Rotor Amperage on Home A/C Units
Lock rotor amperage refers to the amount of current that will be demanded if voltage is applied to a motor and the motors shaft seizes or stops. This is similar to the start up current required by a motor. if the motor or a/c compressor is old, faulty, or in need of replacement the excessive demand for a longer than normal start up can cause the circuit breaker to trip.
