Generac 400 Amp ATS 120/208 3 Phase NEMA 3R Cabinet.

The transfer switch monitors utility power and signals the generator to start when utility power is interrupted. When utility power returns, the transfer switch returns the electrical load from the generator back to the utility. This ensures your most important electrical loads are powered, within seconds, even when you’re away.

All RTS transfer switches are housed in a NEMA/UL Type 3R enclosure, with electrostatically applied and baked powder paint. The Heavy Duty Generac Contactor is a UL recognized device, designed for years of service. The control at the generator handles all the timing, sensing and exercising functions. Designed to operate with the digital Nexus controller used on liquid-cooled QT series gaseous generators from 22- 150 kW.

My Mom and Dad are both in their 80's and live in the country. With the installation of the 6551 I can rest assured that they will never be without power, heat, ac and water. this is a great unit and worked perfectly upon startup. Should have installed this a lot sooner for them.

By the way, my son-in-law also has one for his home. I live in a motorhome or I would have one also.
