30 kW gaseous-fueled standby generator with Brushless Wound-Field alternator and PowerBoost excitation. Mid-range CCL series unit for residential and light commercial backup.
The Kohler 30CCL is a 30-kilowatt gaseous standby generator and the mid-range unit in Kohler's CCL series. It uses a Brushless Wound-Field alternator with PowerBoost excitation, providing sustained short-circuit capability up to 300% of rated current for 10 seconds. The unit operates on natural gas or LP propane and is EPA certified for stationary emergency use.
The 30CCL shares its enclosure and dimensional footprint with the 25CCL and 36CCL, making it a straightforward step-up when 25 kW is not enough headroom but the site does not need the full 36 kW rating.
The 30CCL is a common residential and light commercial installation in our territory. It shares the same engine platform and enclosure as the other CCL models, so service patterns and parts are consistent across the series.

Estimate runtime on this tank
Fuel demand at 75% load
315,000 BTU/hr≈ 315.0 cf/min @ 1,000 BTU/cf
On utility natural gas the runtime is generally unlimited provided the supply line and meter can deliver this BTU/hr at the engine's required inlet pressure (typically 5–14" WC residential, up to 5 psi commercial). Confirm against the OEM's published fuel-pressure spec.

Frequently Asked Questions
What is the standby power rating of the Kohler 30CCL?
The 30CCL is rated 30 kW standby at 60 Hz. It is the mid-range unit in Kohler's CCL gaseous series, offering more headroom than the 25CCL for larger residential loads or small commercial applications.
What is the PowerBoost excitation system?
PowerBoost is Kohler's wound-field excitation design used in the CCL series. It provides enhanced motor-starting capability and sustained short-circuit support up to 300% of rated current for 10 seconds.
Does the 30CCL run on natural gas or propane?
Both. The 30CCL supports natural gas and LP propane with field-selectable fuel switching, like all CCL-series units.
