Ground Fault Sensor
Around all Conductors
Another way a ground fault protector works is with a sensor
around all the circuit conductors. When current is flowing
normally, the sum of all the currents is zero. However, a ground
fault causes an imbalance of the currents flowing in the
individual conductors. When the imbalance reaches a set level,
the shunt trip opens the circuit breaker, removing the load from
the line.
