Circuit breaker electrical power consumption monitoring

摘要

Monitoring electrical power consumption in individual circuits using power sensor devices (1 0) at circuit breakers. A device for sensing electrical power drawn through a circuit having a circuit breaking device in a power line, comprises sensing means, for sensing power being drawn through the circuit breaking device and generating one or more signals indicative of the power being drawn, and a contact configured to be inserted into the circuit breaking device for sensing the power being drawn there-through.
