Cummins Power Generation RSS200-6635 Details and Specifications

Cummins Onan RSS200-6635 200 Amp Automatic Transfer Switch

The RSS Automatic Transfer Switch combines the dependability and flexibility in a small, economical package.  RSS swtiches are suitable for standby power systems in residential and light commercial applications. RSS transfer switches monitor utility power 24 hours a day and 7 days a week.  When utility power becomes unsatisfactory or fails; the controller signals the generator to start, then transfers the load.  When stable utility voltage returns, the transfer switch will automatically switch electrical load from the generator to utility.  No action is required by the home owner.

    Posted by Jesse Shwartz on 4th Dec 2011

    The RS20A 20KW ng/lp generator by cummins onan is a great buy. It turns on automatically which is a great service to us. We know 3 other people that have it. I wouldn't trade it for anything.
