Located within a GFCI device having receptacle openings in its face is a movable contact bearing arm held in either a closed or open position by a latching member connected to a spring loaded reset button. The reset button assumes a first depressed position when the GFCI is in a conducting state, and a second extended position when the GFCI is in a non conducting state. A blocking member located within the body of the GFCI is adapted to be moved to a first position to blocks at least one opening of each receptacle, or to a second position to allow the prongs of a plug to enter the receptacle openings. When the GFCI is in the conducting state, the reset button is in its first position and holds the blocking member in its first position to permit the prongs of a plug to be inserted into the receptacle openings. When the GFCI is in a non-conducting state or is defective, the reset button and the blocking member are in their second positions and the prongs of a plug are prevented from entering the receptacle.

Resettable circuit interrupting devices having self-test and non-resettable or limited resettable power interrupting systems are provided. The permanent power interrupting system activates when a circuit interrupting device is no longer capable of operating in accordance with applicable standards governing such devices or the device is no longer capable of operating in accordance with its design characteristics.

摘要:
A typical duplex GFCI receptacles has two buttons, a test button that, when pressed, shuts off power to the receptacle and down stream devices, and a reset button that, when pressed, restores power to the GFCI and down stream devices. Generally, the test button is pressed to verify that the GFCI will interrupt power to the conductive paths and the reset button is pressed to reset the GFCI. In operation, the test portion of the GFCI will automatically break electrical continuity in one or more conductive paths (i.e., open the conductive path) between line and load sides upon the detection of a fault such as a reverse wiring condition, a ground fault, an open neutral and/or a defective GFCI device. When this happens the reset button in the typical GFCI receptacle is then pressed in an to attempt to restore power. The GFCI here disclosed has only one button which is used for both the test and reset operation. It is pressed to test the GFCI and its associated circuitry for operability and, only if all circuits are operable, upon release it resets the GFCI by closing open conductive paths. If, during operation, the test portion of the GFCI detects a fault and operates to shut off power to the receptacle and down stream devices, the pressing and releasing of the single button will reconnect power to the receptacle and down stream devices only if the GFCI is operational, if an open neutral condition does not exists and/or if the device is not reversed wired.
