Cummins Power Generation RA Series 400 Amp Service Entrance Rated Automatic Transfer Switch, 120/240V Single Phase

The RA transfer switch monitors utility power 24 hours a day 7 days a week.  When utility power becomes unsatisfactory or fails:  the generator set is signaled to start, then automatically transfers the load.  When stable utility voltage returns, the transfer switch will automatically switch electrical load from the generator to the utility.  No action is required by the home or business owner.

The Cummins Power Generation residential transfer switch is integrated with the Cummins Power Generation residential gensets.  These products are listed to UL 1008, the standard for Transfer Switch Safety.
