Claim:
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.
