Automatic Transfer Switches

An automatic transfer switch (ATS) senses a utility outage, starts your standby generator and moves your electrical load to it, then switches back when grid power returns. It is what makes a standby generator hands-free.We stock Generac Guardian RTSN automatic transfer switches in 100, 200 and 400 amp ratings, RTSW three-phase switches, RXSW Smart switches with load management and the RXG16EZA3 with a built-in 16-circuit load center, in single and three phase and 120/208, 120/240 and 277/480 volt versions. Match the amperage to your service panel.See our automatic vs manual transfer switch guide. A licensed electrician must install any transfer switch. Every order ships within the United States for a $70 flat rate and comes with 30-day returns.
