Abstract: A panelboard apparatus includes an enclosure; a first plurality of circuit breakers including a remotely controllable solenoid for actuating the circuit breaker and switching a circuit from a power line through a load; a holder for holding in the enclosure up to a second plurality of circuit breakers including the first plurality of circuit breakers; a controller for controlling up to the second plurality of circuit breakers; a printed circuit connection mechanism for connecting up to the second plurality of circuit breakers to the controller in one of a plurality of configurations, including printed circuit boards having a plurality of interfaces for up to the second plurality of circuit breakers; and a switch selection circuit for selecting one of the configurations in order to determine a location in the enclosure of a first one of the second plurality of circuit breakers.

Abstract: An electronically controlled lighting panelboard characterized by a power line panelboard having a plurality of remotely controlled circuit breakers for opening and closing circuits to corresponding loads. Each circuit breaker is interconnected to an interface which in turn is connected by a multi-conductor cable to an electronic controller or computer.

Abstract: An electronic controller, connected to a digital communication network, is responsive to commands from a master controller to control solenoid operated circuit breakers. The electronic controller also determines the status of all circuit breakers and reports back to the master controller to verify that the command from the master controller was executed and to provide historical data regarding the status of the circuit breakers. The electronic controller is synchronized to the same alternating current (AC) power source as the circuit breakers to control the operation of the respective circuit breakers to minimize electromagnetic interference (EMI) caused by the switching of the circuit breakers. The electronic controller further controls the operation of the circuit breakers to reduce the duty cycle of the power supply for the circuit breaker solenoids.

Abstract: A driver module is provided which cooperates with and drives a hardware interface to a two-way communication and control system. The driver module also performs a number of error checking functions in connection with each message sent out by the master so that faulty messages are not placed on the communication and control network.
