ABSTRACT:
An electrical sub-metering system for making available information associated with power consumption of at least one circuit of a plurality of circuits is disclosed. The system includes an electrical panel board configured to distribute power to the plurality of circuits, a circuit breaker in power connection with a conductor of the at least one circuit, a voltage sensor, a hub to collect the information associated with power consumption from the voltage sensor and the circuit breaker, and a data collector to collect and make available to a user the information associated with power consumption. The circuit breaker includes a current measuring device to measure current through the at least one circuit and is in signal communication with the hub via a single communication interface that has a plurality of communication paths.
