摘要： A power outlet that has a moveable ground pin disposed in a receptacle and has a normal position with the pin extended and an inserted position. An actuator arm with a projection member is coupled to the ground pin and a rotational cam stop abuts the projection member. A pushrod is included that has a shaft, a lever member coupled to the shaft, and a notch for receiving at least part of the cam stop therein. A circuit breaker is disposed in the outlet and has a switch with an OFF position, and an ON position for activating the circuit breaker. The switch is coupled to the lever member. When the ground pin is actuated into the inserted position, the projection member slides away from the receptacle, rotating the cam stop such that it is clear of the notch and the pushrod thereby is enabled to throw the switch from the OFF position to the ON position. The actuator arm spring independently returns the ground pin to the normal position when the pin is removed from the receptacle and works in conjunction with the pushrod spring to throw the switch of the circuit breaker from the ON position to the OFF position if the pin is removed with the circuit breaker switch in the ON position such that the ground pin is returned to the normal position.
