The Kohler 14RCA produces 14kW on propane and 12kW on natural gas. It uses a CH740, 725cc V-twin engine running at 3,600 rpm, with 33kVA of peak motor-starting capability.
The Kohler 14RCA is intended for smaller and mid-sized homes where motor starting matters more than a small increase in running capacity.

Kohler's product page lists slightly different catalog figures (440 lb; 47 × 26.2 × 32.2 in; 67 dB(A) full speed). The table uses the dated April 2026 specification sheet.
What the size and fuel figures mean for installation
Kohler says the 14RCA can be placed as close as 18 inches from a home, citing NFPA guidance for clearance to combustible materials, and tells buyers to check state and local codes; the sheet also offers 3 in and 4 in concrete mounting pads and notes its dimensions are for reference, not installation planning. On propane, 60 ft³/hr at half load converts to about 1.65 gal/hr using Kohler's own factor of 36.39 ft³ per gallon, or roughly 119 gallons over a 72-hour outage (our arithmetic). See the propane tank sizing guide. (Source: 1.)

Where the 14RCA Fits
The Kohler 14RCA is intended for smaller and mid-sized homes where motor starting matters more than a small increase in running capacity. On natural gas, plan against 12kW rather than the propane nameplate. The 33kVA starting rating describes a short motor-start event and cannot be added to the running output.
Inventory the loads you need during an outage, including HVAC starting current, pumps and electric heat. Use the generator size calculator to organize the load list, then have an installer check the design against the exact alternator and fuel configuration.
Equipment Cost and Installation Scope
Kohler’s starting equipment MSRP for the 14RCA is $5,098, checked September 30, 2026. That is not an installed price.
A complete quote should itemize the generator, compatible transfer switch, battery, foundation, electrical and fuel work, permits, commissioning, registration and any load controls or cold-weather accessories. Long trenching runs, gas-meter upgrades and changes to service panels can materially change the total. Compare equivalent scopes from local installers; no national installed average is asserted here.

Transfer Switch and Fuel Supply
Confirm the exact package: 14RCA and 14RCAL are different purchasing choices. The L package is the transfer-switch bundle; do not assume a base-model equipment quote includes the switch. Require the transfer-switch model, amperage, service-entrance rating and load-management accessories as separate named items in the quote. A generator’s kW rating alone does not determine the correct transfer switch.

At full load, the technical sheet lists 193 ft³/hr of natural gas and 81 ft³/hr of LP vapor. Have the installer check fuel supply with the other connected appliances operating; a meter label or short pipe run alone does not establish sufficient capacity.
Ownership and Service
TP-7092 lists oil changes yearly or at 100 hours, oil-filter replacement yearly or at 200 hours, and oil-level checks every 24 operating hours. Use the complete current manual for air-filter, ignition, battery and other service tasks. Severe conditions may require shorter intervals; match the manual to your model and serial number.
