Drive your home with the RS20A standby generator, backed by the engine mastery of Cummins, a world-renowned leader in diesel and natural gas engines. This generator runs efficiently on either propane or natural gas, courtesy of the bespoke engine designed by Cummins. Its compact, stylish design allows for safe placement as close as 18 inches to your home, blending inconspicuously with your outdoor landscape. The unit sports a corrosion-resistant aluminum casing and a galvanized steel interior to minimize noise and vibrations. With sound levels at a modest 65 dB(A), it stands as one of the quietest generators in its category. Enjoy the combination of power and tranquility with our RS20A generator.

Equipped for immediate operation even at freezing temperatures, the Cummins RS20A generator is a robust companion for your home. With additional cold weather accessories, it can function seamlessly in temperatures far below zero, making it an ideal choice for homes throughout the northern United States. This generator isn't just resilient; it's powerful too. Capable of starting and running a 5-ton air conditioner, it simultaneously manages the full energy needs of your household. Not only that, it ensures the safe operation of your delicate electronics with less than 5% total harmonic distortion. Embrace the perfect blend of durability and power with the Cummins RS20A.


The RA Automatic Transfer Switch, seamlessly integrated with the RS series generator, ensures consistent power supply with its state-of-the-art design, compliant with the safety standard UL 1008. This combo is engineered specifically for quick and straightforward installation.
The RA transfer switch operates non-stop, scrutinizing the utility power around the clock. Should utility power falter or fail, it swiftly signals the generator to start, taking over the load automatically. Upon the return of stable utility voltage, the transfer switch smoothly transitions the electrical load back from the generator to the utility. The entire process requires no manual intervention from the homeowner, offering a truly automated power management experience.
