  • Patent number: 4031406
    Abstract: In an electrical load control system, method and apparatus are provided for selectively, individually connecting and disconnecting a plurality of loads to and from a power source. The loads are selectively connected (added), disconnected (shed), and reconnected (restored or added), in a predetermined sequence, wherein the ranking of the loads in such sequence is selectively rotated in a manner which results in a sharing of on and off time and an equalizing of wear among all of the loads. As an example of this operation, a load control system is disclosed in which the consumption of electrical power is varied by periodically shedding and adding individual loads in order to maintain the level of power usage below predetermined limits and yet make full use of the available power within such limits.
