Abstract
Abstract The disclosed emergency control links an auxiliary electrical generator having an auto-start mechanism and an outlet socket, with a utility's power distribution socket, to maintain electrical power at a controlled socket in the event of a utility's power outage. The emergency control has a controlled socket into which the plug of a powered apparatus would be inserted, instead of into the utility's socket; a distribution plug that would be inserted into the utility's socket; and a generator plug that would be inserted into the generator outlet socket. These plug-ins allow use of the control without hard-wiring it into the utility's power lines. The control connects the controlled socket to either the distribution socket or to the generator outlet socket. Detectors sense power at the distribution socket and at the generator outlet socket; and a microprocessor responds to a sensed power outage at the distribution socket to start the auxiliary generator and connect the controlled socket to the generator outlet socket, and responds to restoration of power at the distribution socket to reconnect the controlled socket to the distribution socket and to deactivate the auxiliary power generator.
