ABSTRACT:
A demand controller uses a sensor to detect the operation of an electric load. The sensor operates a relay which supplies power to a magnetic contactor. The magnetic contactor controls power available to a second electric load so that the total amount of power consumed is held below a predetermined maximum. An auxillary switch operates in conjunction with the magnetic contactor to control power available to other loads. A hierarchy is established so that the most important load always has power available, and loads of lesser importance are controlled.
