摘要： An electrical wiring device having a solid-state switch element positioned between the fault detection switch element and the solenoid coil to prevent the solenoid coil from being energized when the circuit interrupter is in the tripped state. The solid-state switch element may have a gate that receives a gate signal that turns the solid-state switch element on when the circuit interrupter is in the reset state and does not receive the gate signal so that the second switch element is turned off when the circuit interrupter is in the tripped state. The gate may be connected to the line terminals and to ground by a mechanical switch responsive to the circuit interrupter state or by another solid-state switch driven by a processor that is programmed to detect whether the circuit interrupter is in the reset state or the tripped state.

摘要： The present invention is directed to an electrical wiring device that includes an automatic test circuit configured to commence an automatic test at a predetermined time such that a test current propagates on a test conductor. The sensor assembly provides a sensor test output responsive to the test current only if both the differential transformer and the grounded neutral transformer are operative. A fault detector circuit is configured to generate a test detection signal in response to the sensor test output only if the fault detector circuit is operable and the at least one power supply is substantially charged. A device integrity evaluation circuit includes a timer that effects a tripped state when a time measurement exceeds a threshold, the test detection signal resetting the time measurement when properly wired before the time measurement exceeds the predetermined threshold but does not reset the time measurement when miswired.

摘要： A tester for a frequency-dependent ground fault interrupt wiring device, including: a tester circuit, including: a switch disposed between a first terminal and a second terminal, wherein a leakage current flows through a leakage path between the first terminal and the second terminal when a voltage is applied across the first terminal and the second terminal, a magnitude of the leakage current being determined, at least in part, by a conductivity of the switch; and a waveform generator configured to generate a periodic output signal having a frequency, wherein the switch is driven to modulate the magnitude of the leakage current such that the leakage current has a frequency substantially equal to a frequency of the waveform generator.
