摘要： The present invention is directed to an electrical wiring device that includes at least one user accessible input mechanism and a test assembly configured to initiate a self-test in response to stimulus signal. The self test determines whether a sensor, a fault detection circuit or a circuit interrupter assembly are in an operational mode or are in a failure mode, the reset stimulus being provided in the operational mode and a reset lockout stimulus being provided in the failure mode. The device also including a reset lockout mechanism coupled to the circuit interrupter assembly and the test assembly. The reset lockout mechanism is configured to disable the reset stimulus in response to the reset lockout stimulus if any one of the at least one sensor, at least one fault detection circuit, or circuit interrupter assembly is determined to be in the failure mode after a predetermined time elapses.

摘要： The present invention is directed to a protection device that includes line terminals coupled to a power source disposed in an electric power distribution system. The protection device is configured to protect a portion of the power distribution system from at least one fault condition. The device includes a receptacle member that includes a housing and a cover. The cover includes receptacle openings configured to accommodate plug contact blades. Receptacle contacts are disposed in the housing. The receptacle contacts are also coupled to the line terminals to thereby establish an electrical connection between the receptacle contacts and the line terminals. Each receptacle contact is in communication with a corresponding receptacle opening. A protective shutter mechanism is integrated into the housing. The protective shutter mechanism is movable from a closed position to an open position upon insertion of the plug contact blades. The protective shutter mechanism is substantially hermetically sealed in the closed position. The protective shutter mechanism is also not movable from the closed position to the open position upon insertion of an object into only one receptacle opening, such that the object is prevented from making contact with the corresponding receptacle contact.
