Cummins 100A Integrated Load Center & ATS, NEMA1

Cummins 100A Integrated Load Center Transfer Switch, RA Series, 120/240V Single Phase, NEMA1 Enclosure

The Cummins RA Series 100A Load Center Transfer Switch is equipped 20 spaces for circuit breakers and a transfer switch in one enclosure. These UL/CSA switch is suitable for residential and light commercial applications and monitors utility power 24/7. The included NEMA1 enclosure is rated for indoor installations only. 

The switch and generator set combination is specifically designed for a simplified, quicker installation. UL 1008 switches are suitable for standby power systems in residential and light commercial applications.  These Cummins RA Series Transfer Switches adhere to National Electric Code (NEC) and National Fire Protection Association (NFPA) requirements.

The Cummins RA series transfer switch is an AUTOMATIC Transfer Switch that 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 homeowner.
