Abstract: A system including a load center monitor (10) connected to a plurality of digitally enhanced circuit breakers (40) by a communication bus (26) provides monitoring and control of an electrical power distribution system. A user port (20) and a service port (22) provide a communication interface with an external computer. Visual indicators (34) and an audible alarm (30) provide for alerting persons to certain conditions in the system. Buttons are provided for CLEAR (38) and RESET (36) functions, and a diagnostic port (24) is also provided. The load center monitor (10) is operable to monitor the operation of the breakers (40) and download information therefrom in the form of historical data. Also, the load center monitor (10) can upload operating information to a breaker (40) in order to change the operation thereof.
