For use within an electrical distribution system, a circuit arrangement is provided which includes a multitude of circuit breakers (20), each of which is operable by remote control in at least open and closed circuit positions. A circuit breaker control circuit is included and has a termination circuit (30) which interprets circuit breaker control signals from an external switch device, a circuit breaker drive board (34), which controls and monitors the multitude of circuit breakers (20), input means and a data path for receiving manual input instructions, a data port and a data path for receiving programming data from an external device, and a switch input data path, coupled to the termination circuit (30), for carrying circuit breaker switch instructions from the termination circuit. The control circuit responds to the manual input instructions, programming data and circuit breaker switch instructions according to a prioritization scheme. |
