Generac’s Home Link Upgradeable Manual Transfer Switch is a pre-wired electrical device that is installed next to your home’s circuit panel. During an outage， it delivers power to hard-wired appliances (such as furnace， well pump and lights) with the push of a button， safely and easily eliminating the need for multiple extension cords. It comes standard with 8 circuits， expandable to 10 circuits. When you are ready to install an automatic home standby generator， a certified electrician will change out the panel located in the Home Link with an automatic switch upgrade panel and new faceplate and it’s ready to be connected to a home standby generator (11 kW maximum).
