| 20110211283 | NOVEL CIRCUIT INTERRUPTING DEVICE WITH HIGH VOLTAGE SURGE PROTECTION - The present invention provides a circuit interrupting device which is capable of providing protection against electrical surge through its innovative electrical discharge design; establishing or discontinuing electrical continuity among the input power source, output load, and user accessible load through its innovative contacts connection/disconnection design; automatic or manual testing of the condition of the key components in the circuit interrupting device by way of a simulated leakage current; and testing whether the device is properly wired by way of a reset switch. | 09-01-2011 |
| 20090161271 | Novel circuit interrupting device with interconnecting reset and test buttons - 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. | 06-25-2009 |
