Abstract

A system according to the present invention including a main utility distribution panel which through corresponding circuit breakers, directly powers facility power line circuits which remain powered continuously, and an ‘off-peak’ utility distribution panel being powered by the main utility distribution panel through a contactor (relay, switch, etc.) controlled by a 24 hour timer, and the ‘off-peak’ utility distribution panel in turn powers facility power line circuits which may be de-energized to provide zero power draw from the main utility distribution panel during a selected time period as provided by the timer, which generally corresponds to periods when the facility is unoccupied and/or the equipment and appliances are turned off.

Claims

1. An off-peak power conservation system, comprising:

a main power distribution panel receiving a power from a source and providing a first plurality of circuits to external devices;

a switch connected to a power source and selectively providing power to an output according to a control signal;

a timer providing said control signal; and

an off-peak power distribution panel receiving power from said switch output and providing a second plurality of circuits to external devices.

2. The off-peak power conservation system of claim 1, wherein said switch power source is one of said first plurality of circuits.

3. The off-peak power conservation system of claim 1, wherein said switch power source comprises said power source to which said main distribution panel is connected.

4. The off-peak power conservation system of claim 1, wherein said switch comprises one of a contactor, a relay and an electrically controlled switch.

5. The off-peak power conservation system of claim 1, wherein said timer comprises a 24 hour timer providing said control signal according to a selected time interval.

6. The off-peak conservation system of claim 1, wherein said timer comprises a programmable timer.

7. The off-peak conservation system of claim 1, wherein said second plurality of circuits are provided via said main distribution panel to corresponding load circuits.
