  • Electrical peak load distributor
    Patent number: 6590304
    Abstract: A method and apparatus for peak load distribution is disclosed. A peak load distributor reduces the demand on a power distribution system by controlling the power available to loads. The apparatus takes an AC current input and a micro-controller executes control algorithms to open and close power outputs to deferrable loads. The outputs are generally put in series with the power applied to a load to disable the load or to lower peak demand.
