Abstract
The present invention provides a circuit interrupting device which contains four pairs of contacts to electrically connect/disconnect to an input power source to a user accessible load and an output power end. The present invention also provides a simulated leakage current generating switch, which is capable of automatically generating a simulated current to test the circuit interrupting device when the power lines are properly wired and in a tripped state. The present invention further provides a reset switch which allows reset when the power lines are properly wired and the reset button is depressed. In addition, the present invention provides a dual-functioned test button which can manually generate a simulated leakage current when a first-level test button is depressed, and can perform a mechanical trip when a second-level test button is depressed.
