Whole House 14kW Generator with 200 Amp Transfer Switch

Kohler Power 14,000 Watt (14kW) Dual Fuel 50-State Air-Cooled Home Standby Generator with 200-Amp Transfer Switch

Product Description

The Kohler Power 14,000 Watt (14kW) Dual Fuel Air-Cooled Home Standby Generator is a permanently installed backup-power solution designed to keep essential residential electrical loads operating during utility outages. The KOHLER 14RCA can operate on either liquid propane (LP) or natural gas (NG), giving homeowners flexibility when selecting a fuel source.

The generator is rated at 14kW on LP and 12kW on natural gas and delivers 120/240V single-phase power at 60 Hz. It uses a KOHLER CH740 V-twin engine, RDC2 controller, and a 2-pole rotating-field alternator. With a compatible automatic transfer switch, the system can automatically detect a utility failure, start the generator, transfer connected loads to generator power, and return them to utility power after service is restored. KOHLER specifies a response time of approximately 10 seconds.

Package Note

The 14RCA generator itself is the generator-only configuration, with the automatic transfer switch sold separately. KOHLER's 14RCAL configuration includes an RXT automatic transfer switch. Because the requested product is described as including a 200A transfer switch, the exact ATS model should be confirmed with the package being offered.

14kW LP / 12kW Natural Gas Output

The 14RCA provides different rated output depending on the fuel being used. KOHLER rates the generator at 14kW on LP and 12kW on natural gas.

This capacity is well suited to many residential backup applications, including essential appliances, HVAC equipment, pumps, refrigeration, lighting, and other household loads. Actual capacity depends on the home's load calculation and the starting requirements of connected equipment.

Dual-Fuel Flexibility

The generator can operate using either natural gas or liquid propane. This allows the system to accommodate homes with different fuel infrastructures.

Natural gas can be supplied through a suitable utility connection, while LP operation requires an appropriately sized propane storage system. Fuel pressure, piping, tank sizing, and installation should comply with KOHLER requirements and applicable local codes.

KOHLER CH740 V-Twin Engine

The 14RCA is powered by a KOHLER CH740 engine with a V-twin cylinder arrangement and 725cc (44 cu. in.) displacement.

The engine operates at 3,600 RPM and is rated at approximately 23.6 HP on LP and 20.5 HP on natural gas.

The engine drives a 2-pole rotating-field alternator designed to provide 120/240V residential power at 60 Hz.

Automatic Standby Operation

When installed with a compatible automatic transfer switch, the generator can provide hands-free backup operation.

When utility power fails, the ATS detects the interruption and signals the generator to start. After the generator reaches operating conditions, the ATS 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.

KOHLER specifies an approximately 10-second response time for the 14RCA.

200-Amp Automatic Transfer Switch

A 200A transfer switch can be used with KOHLER's residential generators, but its rating should not be confused with the generator's actual output.

The 14RCA produces approximately 59A on LP and 50A on natural gas at 240V. A 200A ATS is designed to switch a 200A-rated service or load; it does not increase the generator's output to 200A.

KOHLER offers 200A transfer switches in several configurations, including standard models, load-center models, and service-entrance versions. For example, the RDT-CFNC-0200B-QS7 is a 200A, 240V, single-phase, 2-pole ATS with a load center, while other 200A models are available without a load center or with service-entrance functionality.

For an accurate product listing, the specific ATS model number should be verified.

RDC2 Digital Controller

The RDC2 controller manages the generator's operating functions and provides system-status information. KOHLER identifies the RDC2 as the controller used on the 14RCA and 14RCAL models.

The generator also supports remote monitoring, allowing users to check generator status through compatible KOHLER monitoring solutions.

PowerBoost™ Motor-Starting Capability

KOHLER's PowerBoost™ technology provides enhanced starting capability for demanding motor-driven loads. KOHLER specifically states that the 14kW generator can start and run a 5-ton air conditioner, subject to the actual equipment specifications and installation conditions.

This makes the generator particularly useful for homes where HVAC compressors, pumps, or other motor-driven equipment are part of the backup-power plan.

Durable Aluminum Enclosure

The generator uses an aluminum enclosure intended for outdoor installation. KOHLER states that the enclosure is designed for a wind rating of up to 181 mph and that the panels can be removed without tools to simplify maintenance access.

KOHLER documentation also identifies an 18-inch clearance to combustible materials under the applicable guidelines; local codes may require greater clearances.

The generator measures approximately 47 × 26.2 × 32.2 inches and weighs approximately 440 pounds.

Exercise and Noise

Regular exercise helps keep the standby generator ready for an outage. KOHLER lists several exercise modes for the 14RCA/14RCAL platform:

• Unloaded weekly exercise with complete system diagnostics
• Unloaded full-speed exercise
• Loaded full-speed exercise when used with the required RXT ATS configuration

Each listed exercise cycle is 20 minutes.

KOHLER lists approximate sound output of 63 dB(A) during weekly exercise and 67 dB(A) during full-speed operation.

Fuel Consumption

At 50% load, KOHLER lists approximate fuel consumption of:

Actual consumption varies according to electrical load, fuel pressure, ambient conditions, and other operating factors.

Product Specifications

Specifications are based on KOHLER's current 14RCA information and official product documentation.

*The 200A rating applies to the transfer switch, not to the generator's power output. The exact ATS model and configuration should be confirmed for the particular package.

Typical Applications

The 14kW dual-fuel standby generator is suitable for:

• Small to mid-sized homes
• Essential-load backup
• Central air-conditioning systems
• Refrigerators and freezers
• Well and sump pumps
• Heating systems
• Home offices
• Security systems
• Networking equipment
• Lighting and household appliances
• Homes affected by frequent utility interruptions

Installation Considerations

The 14RCA is designed for permanent installation and should be installed by qualified professionals.

Installation planning should include:

• Electrical load calculations
• Generator sizing
• ATS compatibility
• 200A service configuration
• Natural-gas or LP fuel requirements
• Fuel-line sizing and pressure
• Generator clearances
• Exhaust and ventilation
• Grounding and bonding
• Local electrical and building codes
• Required permits and inspections

The generator should be sized according to the loads it is expected to support. High-starting-current equipment such as air conditioners, pumps, and compressors should receive particular attention during the load assessment.

14RCA vs. 14RCAL

KOHLER offers two closely related configurations:

KOHLER identifies RCA models as generator-only configurations with the ATS sold separately, while RCAL models are bundled with an automatic transfer switch.

Therefore, if a product is specifically advertised as “14kW Dual Fuel with 200-Amp Transfer Switch,” the listing should identify the exact ATS model to establish whether it includes a load center, service-entrance functionality, or other options.
