Abstract
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.
