description An arcing fault protection system for a switchgear enclosure includes an arc diverter for rapidly grounding or crow-barring the electrical distribution system in response to the detection of arcing fault currents in the system. Detection is done through a comparison of current on the main bus against the current through the feeder lines, whereby a difference in current gives a first detection signal. The first detection signal can be used directly, or AND'ed with other detection signals from optical sensors on the feeder lines, to provide the activation signal for operating the arc diverter.
