Abstract

In a system, method and program for monitoring and control of a circuit having a circuit breaker, circuit profile information characterizing the circuit is used to determine a reset strategy for resetting of the circuit breaker when it becomes tripped. The circuit profile information may include an identification of any devices connected along the circuit, and may further include device profile information characterizing such devices. An embodiment of the method includes detecting that the circuit breaker has tripped, receiving device profile information from a device connected along the circuit, using the device profile information to formulate a reset strategy for the circuit breaker, and sending a command as part of implementing the reset strategy. An embodiment of the system includes a system controller operably coupled to the circuit and the circuit breaker, where the system controller is adapted to use circuit profile information to determine a reset strategy.
