Abstract
In an electrical power system for a residential building, a multi-conductor cable supplies power to loads in the residential building from a power supply. A net current returning from loads to the power supply via alternative conductive paths different from the neutral conductor in the cable creates a magnetic field in the vicinity of and inside of the residential building. A net current control device, including a ferromagnetic core, is attached to the multi-conductor cable in order to increase the impedance of the alternate conductive paths to the net current and to increase the net current flowing along the neutral conductor. Various modifications of the net current control device are disclosed.
