Abstract
A circuit for detecting arc faults and over-currents includes two overcurrent detection circuits and a ground fault circuit referenced to a single ground and configured to receive power from a single power supply. Each over-current detection circuit includes a Hall effect current sensor configured to determine a current in a corresponding pole conductor. A method for detecting arc faults and over-currents includes determining a current in a pole conductor using a sensor not in contact with the pole conductor. This circuit and method allow a two-pole breaker circuit to be configured in a form similar to a one-pole circuit and eliminate tripping caused by spurious signals from bimetal sensors.
