<p>A peak load control And power-distributing system for residential or small commercial/industrial use in which some loads are uncontrolled and others are controlled. Current transformers in the main feeder for all loads supply currant to a thermal switch to detect when the power demand exceeds a predetermined value. The thermal switch starts a small synchronous motor having gears driving a shaft with cams operating microswitches for the controlled loads, One cam switch enables the motor to operate through a preprogrammed cycle, and to turn off at the end of a cycle whenever the thermal switch indicates the power demand has dropped below the predetermined value.</p> |
