Abstract
An electrical fault detection and interruption device includes a switch module coupled between input and output ends of current carrying lines, a GFCI (ground fault circuit interrupter) fault detection module for generating a ground fault signal when detecting a leakage current on the current carrying lines, an AFCI (arc fault circuit interrupter) fault detection module for generating an arc fault signal when detecting harmful arcs on the current carrying lines, a drive module for driving the switch module to disconnect the electrical connection between the input and output ends in response to the ground fault signal and/or arc fault signal, a fault signal transfer module for generate a simulated leakage current signal in response to the arc fault signal, and a monitoring module for generating a harmful arc signal to test whether the electrical fault detection and interruption device is functioning normally.
