Cummins 20kW Home Standby Generator Quiet Connect RS20AC with 200-Amp SE-Rated ATS

Cummins 20kW Home Standby Generator

Cummins Quiet Connect 20kW RS20AC with 200-Amp, Service-Entrance-Rated, NEMA 3R Indoor/Outdoor Automatic Transfer Switch supplies your entire home during an outage.

The RS20AC home standby generator connects permanently to your house through the automatic transfer switch and existing natural gas or propane supply. It monitors the power company distribution lines 24/7, then automatically starts and runs when it detects an outage and continues to run until the utility restores power.

Note: The Fuel Inlet Connection has changed locations. See FAQ Tab for details.

Cummins Quiet Connect 20kW

The RA Series 200-Amp Automatic Transfer Switch with NEMA 3R enclosure rated for indoor and outdoor use installs between the utility meter and the main circuit breaker panel. The generator controller automatically starts the generator within seconds after it detects an outage. After startup, it signals the transfer switch to isolate the home from the utility lines and supply it with power from the generator. It all happens automatically within seconds after an outage.

Powerful motor starting capability allows the Cummins RS20AC to start a 5-ton air conditioner while operating a full household load and supply clean power to sensitive electronics at the same time. From a no-load condition to accepting a normal household load, the voltage varies by no more than 1.25 percent. Under steady-state conditions, the RS20AC maintains voltage within 1.25 percent and frequency never varies more than 1.25 percent. Clean, worry free power you can count on.

The Cummins 20kW Home Standby Generator with Intelligent Load Management(**kit sold separately) learns and remembers the power requirements of 240-volt loads like air conditioners. Load management allows a smaller, more fuel-efficient generator to manage up to four central air conditioners or other heavy loads. The A051C329 Cummins Load Management Kit controls two appliances like an air conditioner or water water. Two kits can control four loads.

Monitor and control the Cummins Quiet Connect 20kW from almost anywhere. Advanced Remote Access (no cost) uses the highway safety and monitoring network for vehicles and equipment. Check generator status, program exercise periods, even manually start and stop the generator using the Cloud Connect Smartphone App on phones, tablets, or computers. Send performance data directly to your authorized dealer for worry-free maintenance.

A compact, efficient design packs the Cummins 20kW Generator into a 34 x 36 x 27-inch enclosure. The generator meets NFPA 37 code for installation just 18-inches from the home. A sleek and attractive cabinet blends into the landscaping.

Patented sound technology and an advanced housing design with a corrosion resistant aluminum exterior and galvanized steel interior reduces noise and vibration. Sound levels of just 65dBA make Cummins Quiet Connect 20kW home standby generators among the quietest in their class.

The Cummins RS20AC comes equipped for operation down to zero degrees out of the box. Cold weather accessories extend the operating temperature well below zero for reliable starts across the northern continental United States.

A patented “Crank-Only” mode reduces wear and tear during the exercise cycle. The engine cranks without starting while the controller performs diagnostics. The Cummins Quiet Connect 20kW generator gets the exercise it needs, while the controller ensures that the generator is operating correctly. This eco-friendly feature saves fuel and produces less noise than operating the generator for 5 to 20 minutes every week.

A Cummins QSJ999G Engine powers the RS20AC home standby generator. Cummins, the world-class leader in diesel and natural gas engines, designed and built the propane or natural gas engine. The installer selects the fuel-type during installation.
