Surge suppressor

摘要

A lighting installation includes a light fixture having a socket adapted to electrically connect to at least one lamp, the light fixture having a line voltage input, a neutral input and a ground input. Also included is a circuit for suppressing electrical surges including output leads for line voltage and neutral to the socket, a first varistor connecting the line voltage input and ground input, a second varistor connecting the line voltage input and neutral input, a third varistor connecting the ground input and neutral input, a resistor connecting the line voltage input and line voltage output, and a resistor connecting the neutral input and neutral output.
