This smart switch is service entrance rated. It comes complete with a 200 amp main circuit breaker. The 6551 and RTS-W-200A3 smart switch is a good package for many homes. It may also be suitable for small business.

 

ENGINE/FUEL

Model 6551 is powered by the Generac 999cc OHVI® engine. It has a long history of strong, reliable performance, and has been one of their go to engines for several past model lines. The generator comes configured for natural gas and will output 19.5kW. It can easily be configured for LP operation during installation, which will provide the full 22kW

 

ENCLOSURE

The aluminum outer enclosure is extremely durable. It will look beautiful on your property for many years. This generator includes the decorative fascia that goes around the base. It creates a beautiful look whether the generator is installed on pea gravel or a gen pad. An external side door allows access to the 100 amp main circuit breaker and ground fault circuit interrupter (GFCI) receptacle. It has external LED indicator lights to show generator condition at all times. Model 6551 has been 3rd party tested. This testing concluded the generator enclosure would contain an internal fire. If the building structure has a one hour fire rating the generator may be located 18” from your home or business. Generator placement is always subject to local building codes.

 

OPTIONS

Compatible with Generac Mobile Link to keep you aware of your generator condition at all times. We have an optional cold weather kit model #6212 to keep your generator ready to run in the harshest conditions.
