Patent ID: 8884607

Claim:
An apparatus comprising: a plurality of interrupting devices, each having a mains electricity input and a mains electricity output and operable to disconnect the mains electricity input from the mains electricity output upon receipt of an overcurrent control signal; a plurality of current detectors corresponding to the plurality of interrupting devices, each comprising: a mains current circuit disposed in a corresponding mains electricity supply path; and a measurement circuit operable to measure a voltage drop across the mains current circuit; and a control circuit coupled to the plurality of interrupting devices and the plurality of current detectors, the control circuit operable to: receive voltage drop inputs from the plurality of current detectors; produce the overcurrent control signals upon detection of respective overcurrent conditions based upon respective voltage drop inputs; and determine and store a series of discrete current measurements of at least one of the plurality of current detectors; and communicate one or more of voltage, overcurrent or current data to at least one remote device via a network interface.
