| 20110116212 | Method of Recovering Power Losses In A Residential, Commercial, or Industrial Facility - Disclosed is a method of installing a passive electrical element, or voltage control guard (VCG), in an electrical circuit of a circuit breaker box in an electrical network of a residential, industrial, or commercial facility. The VCG has an inherent capacitance, resistance, and inductance and has at least two electrical leads that are installed to establish a parallel connection on a neutral bus bar in the circuit breaker box, with a portion of a current on neutral bus bar flowing through the VCG. When the VCG is properly installed, the VCG converts wasted or lost power in the electrical network to useable power, thereby reducing the total electrical consumption of the facility. | 05-19-2011 |
