Abstract:
A monitor control system and method for an electrical distribution system includes a trip unit of a circuit breaker. A sensor is associated with the electrical distribution system and coupled to the trip unit wherein the sensor is connected to one or more components of the electrical distribution system to detect whether the electrical distribution system is being serviced when a presence of a human being is also detected. A selector is coupled to the trip unit and configured to select maintenance mode parameters to define a mode of operation of the trip unit wherein in the maintenance mode arc flash reduction or tripping delay reduction is provided such that the trip unit operates based on the maintenance mode parameters.
