Abstract

A wire management method using a wire manager including current sensing features provides input for power measurement and management systems. The wire manager may be a single wire or single bundle retaining device with a current sensor such as a hall effect sensor integrated therein, or may be a multi-wire management housing with multiple current sensing devices disposed inside for measuring the current through multiple wires. The wires may be multiple branch circuits in a power distribution panel or raceway, and the wire manager may be adapted for mounting in such a panel or raceway. Voltage sensing may also be incorporated within the sensors by providing an electrically conductive plate, wire or other element that capacitively couples to the corresponding wire.

Claims

1. A method of measuring energy usage in a building power distribution system, the method comprising:

installing a wire manager having a wire manager body within a raceway or panel of the building power distribution system;

controlling a position of multiple wires corresponding to multiple branch circuits of the power distribution system by directing the multiple wires through the wire manager body, wherein the wire manager body defines a plurality of apertures along one side of the wire manager body through which individual corresponding ones of the multiple wires are inserted by the directing;

isolating internal circuits of the wire manager from other circuits within the building power distribution system by installing a removable cover on the wire manager body;

securing the multiple wires within corresponding ones of multiple current sensors affixed to a printed wiring board by closing clamshell housings of the multiple current sensors around individual corresponding ones of the multiple wires, wherein the printed wiring board is mounted in the wire manager body so that ends of individual ones of the multiple current sensors are positioned within corresponding ones of the apertures;

measuring current in the multiple wires with current sensing elements integrated in the corresponding current sensors; and

communicating results of the measuring to an external system that are indicative of energy usage within the building power distribution system.

2. The method of claim 1, wherein the measuring further comprises sensing electric potentials at each of the multiple wires using voltage sensing elements integrated in the sensors.

3. The method of claim 2, further comprising transmitting a result of the measuring to an external system from an interface integrated with the wire manager body.

4. The method of claim 3, wherein the interface is a circuit integrated on the printed wiring board.

5. The method of claim 1, further comprising transmitting a result of the measuring to an external system from an interface integrated with the wire manager body.

6. The method of claim 5, wherein the interface is a circuit integrated on the printed wiring board.
