Patent ID: 8666685

Claim:
A system for monitoring a plurality of circuit branches coupled to an input line within a load center, the system comprising: a plurality of current sensors, each configured to be removeably coupled to at least one of the plurality of circuit branches and to produce a signal having a level related to a current level of the one of the plurality of circuit branches; a communications bus; a plurality of sensor circuits, each coupled to an associated one of the plurality of current sensors and configured to be removeably coupled to the communication bus, wherein each one of the plurality of sensor circuits is configured to convert the signal from the associated one of the plurality of current sensors to a digital measurement signal and provide the digital measurement signal to the communication bus; and a controller configured to be coupled to the communication bus and configured to receive the digital measurement signal from each sensor circuit over the communication bus and transmit data related to the digital measurement signal from each sensor circuit to an external client.
