Each circuit breaker in an electrical distribution system is paired with an electronic device which includes a computer processor and an electrical sensor. The processor of each device receives sensory current signals from the sensor contained in the same device, converts the signals from analog to digital data, and processes this digital data into information indicative of the direction of current in the vicinity of the circuit breaker with which the device is paired. The devices are networked (e.g., via Ethernet) so that each device's processor receives the current direction information which is produced by every other device, and processes the entirety of the current direction information which is both locally and remotely produced, thereby identifying the suspected fault in the system and deciding whether to send an activation signal to the circuit breaker with which the device is paired in order to isolate the fault.
