Our Cummins RS20A Is Beloved
By  
Texas
Review Posted 06/26/2022 
We've had our RS20A for a year now. The maintenance tech performed the first checkup and told me he was so happy to see that we had a Cummins. He went on to say that as reliable as they are, if something were to go wrong, it would diagnose itself. That is what he liked about it over the other popular standby generator brands. I exercise it under full load every 90 days by just dropping the breaker on the ATS. It comes right up in less than 10 seconds and runs both my ACs, a 3 ton and a 5 ton with ease. This baby is also proven to prevent short brown outs as it senses any fluxuation and comes on line immediately and stays on line until the power is stable.

The most interesting feature about our RS20A is it's ability to learn the characteristics of our home's electrical load and apply that learning to protecting itself from overloads that would shut it down. We run everything in the house, washer, dryer --- everything without worry. Also, I like the way it looks at the side of the house and how quiet it is. There is more to say, but too little typing room. Cummins products are tried and true and made to last. If you want quality and durability, look no further than a Cummins standby generator.
