APC Universal Transfer Switch 6-Circuit 120V for $341.66

The APC Universal Transfer Switch (UTS) monitors the utility power conditions of your home or small business and safely transfers loads to two backup power sources when a power disturbance occurs. Power is conveniently distributed from the backup sources to as many as ten circuits, keeping critical loads such as lights, furnaces, well pumps, and home appliances up and running during an outage. Unlike other transfer switches that are compatible only with generators, the UTS can also be connected to a UPS.
