Cummins RS20AC A061C602 20kW WiFi Quiet Connect™ Series Standby Generator LP/NG with 200A Automatic Transfer Switch Scratch and Dent
The RS20AC is a home standby generator permanently connected to your house by an automatic transfer switch. The generator operates on your home's existing natural gas (18kW) or LP Gas (20kW) supply. Access the generator controller on any smartphone, laptop, tablet, or desktop computer. Operate the generator manually, program the exercise cycle, view status and reports, or schedule maintenance.
