Kohler Power 14,000 Watt (14kW) Dual Fuel 50-State Air-Cooled Home Standby Generator with 100-Amp Transfer Switch
Product Description
The Kohler Power 14,000 Watt (14kW) Dual Fuel 50-State Air-Cooled Home Standby Generator is a permanently installed backup-power system designed to keep important residential electrical loads operating during a utility outage. The KOHLER 14RCA runs on either liquid propane (LP) or natural gas (NG), providing flexibility for different home fuel systems.
The generator delivers 14kW on LP and 12kW on natural gas at 120/240V, single-phase, 60 Hz. It is powered by a KOHLER CH740 V-twin engine with 725cc displacement and uses an RDC2 controller. With a compatible automatic transfer switch, the system can automatically detect a utility failure, start the generator, transfer the connected loads to generator power, and switch back when utility service is restored. KOHLER specifies a response time of approximately 10 seconds.
Package Configuration Note
KOHLER lists the 14RCA as a generator-only model, with its automatic transfer switch sold separately. A 100A, 240V single-phase transfer switch can be paired with compatible KOHLER residential generators, including the RXT and RDT families. The exact transfer-switch model should be confirmed for the particular package because KOHLER offers standard, load-management, and service-entrance configurations.

14kW LP / 12kW Natural Gas Output
The generator's rated output varies according to the selected fuel.
| Fuel | Rated Output | Rated Current at 240V |
|---|---|---|
| Liquid Propane | 14kW | 58A |
| Natural Gas | 12kW | 50A |
KOHLER also lists a 33 kVA peak motor-starting rating at 240V, providing additional starting capability for loads with high initial demand.
The generator's actual usable capacity depends on the home's electrical load calculation and the starting requirements of connected equipment.
Dual-Fuel Operation
The 14RCA supports both natural gas and liquid propane, allowing homeowners to select the fuel source best suited to their property.
Natural gas can be supplied through a properly sized utility connection, while LP operation requires an appropriately sized propane storage system. Fuel pressure, piping, tank capacity, and connections should meet KOHLER specifications and applicable local regulations.
KOHLER CH740 V-Twin Engine
The generator is powered by a KOHLER CH740 V-twin engine with 725cc (44 cu. in.) displacement.
The engine operates at 3,600 RPM and is rated at approximately:
- 23.6 HP on LP
- 20.5 HP on natural gas
The engine drives a 2-pole rotating-field alternator designed to produce 120/240V residential power at 60 Hz.
100-Amp Automatic Transfer Switch
A compatible 100A automatic transfer switch (ATS) continuously monitors the utility power supply. When an outage occurs, the ATS signals the generator to start and transfers the connected loads to generator power. Once utility power returns, the ATS transfers the loads back to the utility and the generator shuts down according to its programmed sequence.
KOHLER offers 100A ATS options including:
- RXT-JFNC-0100A-QS7 — 100A, 240V, single-phase, 2-pole standard RXT ATS
- RXT-JFNC-100CSEQS3 — 100A, 240V, single-phase, 2-pole service-entrance RXT ATS
- RDT-CFNC-0100A-QS7 — 100A, 240V, single-phase, 2-pole RDT ATS
The RXT standard model includes load-shedding capability, while the service-entrance model also provides load-management capability. The RDT model is designed for single-phase residential/small-business applications.
Important: 100A ATS vs. Generator Output
The 100A rating belongs to the transfer switch, not the generator.
The 14RCA itself is rated for approximately 58A on LP and 50A on natural gas at 240V. A 100A transfer switch does not increase the generator's electrical output to 100A.
RDC2 Digital Controller
The RDC2 controller manages the generator's operating functions and provides system-status information. It is designed to support automatic standby operation when paired with a compatible transfer switch.
The system also supports remote monitoring, allowing homeowners to monitor generator status through compatible KOHLER solutions.
PowerBoost™ Technology
KOHLER's PowerBoost™ technology helps the generator handle demanding motor-starting loads without requiring a larger generator.
KOHLER identifies the 14kW model as capable of starting and operating a 5-ton air conditioner, although actual performance depends on the specific air-conditioning equipment and the overall electrical load. A professional load assessment should still be performed before installation.
Durable Aluminum Enclosure
The 14RCA features an aluminum outdoor enclosure designed for durability in demanding weather conditions. KOHLER states that its enclosure design is rated to withstand winds of up to 181 mph.
The generator measures approximately 47 × 26.2 × 32.2 inches and weighs approximately 440 pounds.
Exercise and Operating Noise
Regular exercise helps maintain generator readiness. The 14RCA is designed to perform automatic exercise routines and system diagnostics.
KOHLER lists approximate sound levels of:
- 63 dB(A) during weekly exercise
- 67 dB(A) during full-speed operation
Actual perceived noise can vary depending on installation location, surrounding structures, distance, and operating conditions.
Fuel Consumption
At 50% load, KOHLER lists approximate consumption of:
| Fuel | Consumption at 50% Load |
|---|---|
| Natural Gas | 124 cfh |
| Liquid Propane | 60 cfh |
Actual consumption varies according to load, fuel pressure, ambient temperature, and other operating conditions.
