Fuel Flexibility: Natural Gas or Propane

The Cummins RS60 Quiet Connect 60kW Generator 277/480 Volts 3 Phase operates on natural gas or LP propane. Fuel selection is field-configurable.

Fuel consumption rates:

Natural Gas

• Full load: 933.8 cubic feet per hour

• Half load: 545.0 cubic feet per hour

Propane

• Full load: 10.17 gallons per hour

• Half load: 5.96 gallons per hour

For facilities with municipal gas lines, a natural gas standby generator ensures uninterrupted fuel supply. Remote sites often prefer propane for storage flexibility.

Choosing the correct fuel source depends on:

1. Utility availability

2. Fuel storage regulations

3. Runtime expectations

4. Local code requirements

---

Code Compliance and Certification

The RS60 is a UL-2200 listed generator and complies with:

• U.S. EPA emissions standards

• IBC Seismic requirements

• NFPA 110 capable (with proper installation)

This ensures it meets strict commercial building code requirements. For contractors and facility managers, compliance simplifies inspections and permitting.

Practical Installation and Setup Considerations

Before installation, follow these best practices:

1. Prepare a reinforced concrete slab.

2. Confirm automatic transfer compatibility.

3. Size gas lines correctly for full-load operation.

4. Verify three-phase distribution panel compatibility.

5. Schedule professional commissioning.

The RS60 integrates seamlessly into commercial backup power systems when installed correctly.

If your power demand analysis shows future expansion potential, compare with the Cummins RS80 Quiet Connect 80kW 120/208V 3 Phase Generator for scalability planning.
