Patent number: 10574053Abstract: A method and system for supplying electric power to a plurality of priority loads from either a utility power source or a secondary power source, such as a generator. A control unit monitors the power draw by each of a plurality of priority loads and base loads during the supply of electric power from the utility power source. When the supply of power from the utility power source is interrupted, the control unit determines the number of the priority loads that can be powered by the secondary power source based on the monitored power draw of the priority and base loads prior to power interruption. The secondary power source is activated and the determined number of priority loads is immediately connected to the secondary power source without delay. When the utility power source returns, the system and method transfers utility power back to all of the priority and base loads.Type: GrantFiled: January 3, 2018Date of Patent: February 25, 2020Assignee: Briggs & Stratton CorporationInventors: Brandon M.
