Abstract

An electrical isolation device (10) is provided for use in an electrical distribution network having a plurality of branch circuits (b1-b4) each defined by line and neutral conductors connected between a power source (UT) and a load (11-14), the line conductor being electrically connected to one of a plurality of line buses (11 and 12) at an electrical distribution panelboard, the neutral conductor being electrically connected to a neutral bus (N) at the electrical distribution panelboard. The isolation device includes a capacitance coupled between the line and neutral conductor of each of the branch circuits and is designed to provide a low impedance path for an arcing fault occurring on the line conductor of the branch circuit. The capacitance is sufficiently large to provide power factor correcting current.
