Abstract
A system and method are provided to detect a fault on a circuit. A current sensor is provided for sensing current on at least one line conductor and/or a neutral conductor on a circuit, and a switch is operated between at least first and second positions to selectively control a signal pathway on the at least one line conductor or the neutral conductor in relations to the sensor. The sensor performs a first current measurement corresponding to current across one conductor from the at least one line conductor and the neutral conductor in the first position, and a second current measurement corresponding to a current balance or imbalance between the conductors in the second position. The current sensor outputs the first current measurement for detecting an arc fault in the first position, or the second current measurement for detecting a ground fault in the second position.
