Abstract
A low voltage electric power monitoring and circuit breaker system includes two processors. The first processor activates the circuit breaker when an overcurrent condition is detected and the second processor monitors the current sensed by the first processor and logs overcurrent values which arm the breaker as well as overcurrent values existing at the time the breaker is tripped.
