Everything you need to know
Configuration: 120/208V, 3-Phase, 60 Hz · Part #A054F636.
The Cummins C50N6 is a 50 kW natural gas or LP standby generator from the Cummins QuietConnect commercial-grade series — a liquid-cooled machine built to carry estates, agricultural operations, and light-commercial facilities through extended utility outages. Permanently connected to your natural gas or propane supply, it runs as long as fuel flows, with no refueling and no tanks to monitor.
Automatic, Hands-Off Backup
Paired with a Cummins automatic transfer switch, the C50N6 monitors utility power continuously, starts within seconds of an outage, and transfers the full load automatically — then returns to utility power and shuts down once the grid is restored. No manual switching, no cords, and no downtime for the systems that can't go dark.
Commercial-Grade Power & Control
Cummins PowerCommand control governs the C50N6 with precise voltage and frequency regulation and strong motor-starting capability — critical for hard-starting loads like central air conditioning, well and irrigation pumps, refrigeration, and three-phase equipment. It's the same power pedigree Cummins builds for hospitals, data centers, and critical facilities, scaled for estate and light-commercial use.
Natural Gas or Propane — Continuous Runtime
Connected to a utility natural-gas line, the C50N6 runs continuously through even multi-day outages with no refueling. On LP it draws from your on-site propane tank. Either way you get clean, continuous power without the fuel logistics of diesel, ideal anywhere a gas line is available.
