ABSTRACT:
Conservation system for use with a power source which supplies power over premises wiring to utilization equipment such as lighting equipment. Contactors and a control system are provided to temporarily interrupt the supplying of power from the power source to at least a portion of the utilization equipment. At least one switching circuit is connected in series between the power source and that portion of the utilization equipment. The switching circuit is responsive to the temporary interruption of power to open the circuit between the power source and that portion of the utilization equipment and to maintain that circuit open after the temporary interruption of power ceases, thereby automatically deenergizing that portion of the utilization equipment upon interruption of the power.
