80kW Generators

80kW standby generators

The 80kW class is where commercial standby work begins in earnest: liquid-cooled engines, three-phase output, and a fuel system that has to be designed rather than plugged in. This collection carries 39 units, led by Cummins and Kohler, priced from roughly $26,600 to $41,600 before freight and installation.

Specification decisions

• Voltage and phase. 208V and 480V three-phase are the common commercial services; confirm the service voltage and whether the generator must match it directly or through a transformer.
• Fuel supply. Natural gas requires a dedicated regulator and adequate pressure at the unit; LP requires tank sizing for the required runtime. A 80kW unit at full load consumes a lot of fuel - the tank or line size is a design calculation.
• Transfer switch. Service-entrance or standalone, open-transition or closed-transition. The switch rating must match the service, not the generator output.
• Enclosure and sound. Level 1 and Level 2 enclosures differ by dBA and by cost; many jurisdictions have noise ordinances that decide this for you.

Installation reality

Expect a concrete pad, bollards, exhaust clearances, and a rigging plan - an 80kW unit with enclosure is well over 2,000 lb. NEC Article 702 governs the electrical side; fuel piping falls under NFPA 54/58 and local gas codes. Commissioning normally includes a load bank test; ask for it in writing.
