Control system for domestic electrical energy supplies - includes device to limit energy to predetermined level even through total energy requirement may exceed this level

摘要

Domestc electrical energy distribution system feeding a number of heating circuits supplied from two different phases a neutral and also a number of electrical appliances, has as many contactors as there are heating and appliance circuits, plus an automatic switching device which operates continuously, which periodically and successively cuts off the supply to the contactor windings of the heating circuits. Has a manual multiposition switch, which for each position, controls a relay whose contacts feed the winding of, an appliance selected by the switch and cuts off the supply to the contactor windings of certain predetermined heating circuits.
