ABSTRACT:
The present invention provides a novel circuit interrupting device capable of performing an automatic end-of-life test using a status test switch (KR-1), when the device is properly wired and the reset button is at a tripped state. The present invention is further characterized by its novel reset mechanism using a reset start switch (KR-4), a novel electrical connection between an input power end, an output power end, and a user accessible end to establish or discontinue electricity in the circuit interrupting device, and a novel test mechanism which uses a test button in connection with a rotatable lever to provide a dual test function to either test the components of the circuit interrupting device when the power is on and the reset button is at a reset state, or provide a mechanical trip when the reset button cannot be tripped by artificially generating an electric leakage current. Finally, the present invention provides a method to monitor the end-of-life of the device.
