Includes Factory Installed Cold Weather Kit & In-home Display,
Runs on Natural Gas or LP
3 - 4 weeks from time of order.
The Cummins Onan RS20A ensures that life goes on even when the power goes out. The RS20A runs on Natural Gas or LP Vapor Propane and is manufactured with high-quality commercial-grade materials for safe and reliable performance. This unit comes equipped with a sound insulated, weather protective enclosure for outdoor installation. Quietest generator in its class, producing only 62d(b)a under a full load at 7 meters. Third party tested! This generator is not approved for use outside of the USA.
The Cummins Onan RS200 amp service entrance rated automatic transfer switche works hand-in-hand with the RS20A permanently installed, home standby generator. The transfer switch immediately senses when utility power has been interrupted, transferring responsibilities to the generator. When the utility power is restored, the transfer switch automatically transfers back to utility power, shutting down and instantly resetting itself for the next power interruption with no action required by the homeowner.
Electrical connections must be made and fuel systems installed by qualified and licensed personnel. Improper installations present hazards, which can result in personal injury or property damage. Please contact a licensed residential electrician and your local Natural Gas or Propane supplier for these services.
