1. An energy management system for reducing the power consumption of a plurality of normally energized loads comprising:

  • means providing a source of interrupter actuating voltage;

    first timing means having a 168-hour timing cycle;

    second timing means having a 24-hour timing cycle;

    third timing means having a fractional day timing cycle; and

    a plurality of independently acting subcircuits each includinginterrupting means capable of interrupting the flow of energy to a particular one of said plurality of loads,first switching means responsive to said first timing means and operative to apply said actuating voltage to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to its corresponding load during a selected period of said 168-hour timing cycle,second switching means independent of said first switching means but connected in parallel circuit therewith and responsive to said second timing means and operative to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to said corresponding load during a selected period of said 24-hour cycle, andthird switching means independent of said first and second switching means but connected in parallel circuit therewith and responsive to said third timing means and operative to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to said corresponding load during a selected portion of the fractional day timing cycle.
