1. An energy management load panel arrangement, comprising:

  • a load panel enclosure;

    a plurality of circuit breakers secured in the enclosure, each of said circuit breakers capable of opening and closing in response to a control signal so as to interrupt an associated current path;

    at least one microcomputer for generating said control signals to control said circuit breakers and their associated current paths;

    a real-time-clock circuit, coupled with said at least one microcomputer, for automatically providing the time of day;

    a volatile memory circuit for storing time-event data which is used to indicate when at least one of said control signals should be generated; and

    an electronic multi-layered capacitor coupled to said volatile memory for providing operating power thereto for a significant period of time during a power outage;

    wherein the time-event data is retained during the power outage so that the circuit breakers are timely controlled, after the power outage, in response to said control signals, and the microcomputer automatically reads the time of day in the real time clock and, based thereon, corrects the time-event data in the volatile memory.
