摘要： A wiring device including an interrupting device, a fault detection circuit, and a testing circuit. The interrupting device is electrically connecting one or more line terminals to one or more load terminals. The fault detection circuit is configured to detect a fault condition and generate a fault detection signal in response to detecting the fault condition. The fault detection signal being provided to the interrupting device to place the interrupting device in a tripped condition. The testing circuit is configured to determine a frequency of an input voltage at the one or more line terminals, filter the frequency of the input voltage, determine whether the filtered frequency is within a predetermined range, and when the filtered frequency is within the predetermined range, perform a test of the wiring device.

摘要： A self-testing fault detector having a line side and a load side and a conductive path there between is provided. The self-testing fault detector includes an auto-monitoring circuit electrically coupled to a fault detection circuit and an interrupting device and it continuously monitors one or more signals to determine an operating state of the fault detector. At least one of the monitored signals includes a fault detection signal, wherein if said automonitoring circuit determines that the fault detection circuit is not properly driving the interrupting device, the automonitoring device converts an input-output port receiving the fault detection signal from an input to an output and drives the interrupting device into a tripped condition using the input-output port.

摘要： A circuit interrupting device including one or more line terminals for connecting to an external power supply, one or more load terminals for connecting to an external load, one or more contacts electrically connecting one or more line terminals to one or more load terminals; and an auto-monitoring circuit. The auto-monitoring circuit continuously monitoring one or more signals to determine an operating state of said circuit interrupting device. Wherein if said auto-monitoring circuit determines that said circuit interrupting device has reached its end-of-life and it is determined that the contacts have not failed, then a signal is driven to a first level to actuate a switch and open the contacts. Wherein said signal is further driven to a second level to inhibit said circuit interrupting device from resetting when it is determined that contacts of said interrupting device have failed. Wherein the second level has a voltage greater than zero volts.
