Abstract:
The present invention provides a novel circuit interrupting device, preferably a ground fault circuit interrupter, which contains a reset button that is capable of interacting with a test button to perform an end-of-life-component test on the circuit interrupting device. The circuit interrupting device also contains a reset switch coupled to the reset button which is capable of disallowing reset if the device is miswired and/or fails the end-of-life-component test. Only when the circuit interrupting device is properly wired, in a tripped state, and all of the key components in the circuit interrupting device are working properly, the depression of the reset button allows the device to be reset.
