Kohler Power RDT Series 240V 200A Automatic Transfer Switch with Service Entrance
Product Description
The Kohler Power RDT Series 240V 200A Automatic Transfer Switch with Service Entrance is designed to automatically manage the transfer of electrical power between a utility source and a compatible standby generator. When utility power fails, the ATS signals the generator system and transfers the connected electrical load to generator power. Once utility service is restored, it automatically transfers the load back to the utility source and allows the generator to shut down according to its programmed sequence.
The 200A service-entrance configuration is factory-equipped with a normal-source disconnect circuit breaker, allowing the transfer switch to serve as the service disconnect for applicable installations. The unit uses a 240V, single-phase, 2-pole, 3-wire configuration and is designed for use with single-phase KOHLER residential and small-business generators.

Automatic Backup Power Transfer
The RDT automatic transfer switch continuously monitors the utility source. If an interruption occurs, the ATS coordinates with the standby generator to initiate the backup-power sequence. Once generator power is available, the transfer mechanism moves the connected loads from the utility source to the generator.
When utility power returns and is stable, the RDT transfers the loads back to the normal source and the generator completes its shutdown cycle. This automatic operation removes the need for manual source switching during a power outage.
200A Service-Entrance Design
A major distinction of this model is its service-entrance rating. Unlike a standard transfer switch, the service-entrance version is factory-equipped with a normal-source disconnect circuit breaker. This allows the ATS to be incorporated into electrical service configurations where the transfer switch is required to provide the service disconnect function.
The 200A service-entrance model has a 22,000 RMS symmetrical ampere withstand and close-on rating at 240 VAC according to Kohler's RDT specification documentation.
Because service-entrance equipment affects the building's electrical service, installation and configuration should be performed by qualified electrical personnel in accordance with applicable codes and the manufacturer's installation requirements.
MPAC 500 Controller
The RDT uses a microprocessor-based MPAC 500 controller to monitor and coordinate transfer-switch operation. The controller provides status information through the transfer switch's indicator system and manages the automatic transfer and retransfer sequence.
The unit includes:
- Position-indicating LEDs
- Source-available indicating LEDs
- Common/fault relay
- Load-control time-delay functionality
An accessory board with an audible alarm and an external alarm module are available as options.
Load Management Capability
The RDT supports optional load shedding and includes a load-control time delay. Load management can help prevent selected electrical loads from being energized simultaneously when generator capacity is limited.
This feature can be useful in standby systems where certain nonessential loads need to be controlled to keep generator demand within the available capacity.
Durable Aluminum Enclosure
The transfer switch uses a corrosion-resistant aluminum enclosure designed for indoor or outdoor installation. The service-entrance configuration has a larger enclosure than the standard 200A RDT because it incorporates the service disconnect equipment.
The service-entrance model measures approximately 33.8 inches high × 18.6 inches wide × 6.4 inches deep and weighs approximately 26 lb. (12 kg).
Generator Compatibility
The current Kohler listing identifies the RDT 200A service-entrance model as compatible with all single-phase KOHLER residential and small-business generators.
This makes the RDT a suitable choice for installations where an automatic transfer switch needs to coordinate a KOHLER standby generator with the building's utility service.

Ideal Applications
The Kohler RDT 200A service-entrance ATS is well suited for:
- Residential standby generator installations
- Small-business backup power systems
- Whole-building standby power
- New generator installations
- Existing electrical-service upgrades involving standby generation
- Applications requiring a service-entrance transfer switch
- KOHLER residential and small-business generator systems
Service-Entrance vs. Standard RDT
It is important to distinguish this model from the standard RDT-CFNC-0200A-QS7.
| Feature | 200A Service Entrance | 200A Standard |
|---|---|---|
| Model | RDT-CFNC-200ASEQS4 | RDT-CFNC-0200A-QS7 |
| Rating | 200A | 200A |
| Voltage | 240V | 240V |
| Phase | Single phase | Single phase |
| Service Entrance | Yes | No |
| Normal-Source Disconnect | Included | — |
| Load Center | No | No |
| Controller | MPAC 500 | MPAC 500 |
| Approx. Weight | 26 lb. | 15 lb. |
| Approx. Dimensions | 33.8 × 18.6 × 6.4 in. | 24.1 × 13.4 × 7.0 in. |
The standard RDT is considerably smaller and lighter, while the service-entrance model incorporates the additional disconnect equipment required for its service-entrance configuration.
Installation Considerations
The RDT 200A service-entrance ATS is electrical service equipment and should be installed by a qualified electrician familiar with automatic transfer switches, standby-generator systems, and applicable electrical codes.
Before ordering, verify:
- Generator compatibility
- Service voltage and phase
- 200A service rating
- Service-entrance requirements
- Available fault current
- Enclosure requirements
- Local electrical-code requirements
- Required load-shedding configuration
The service-entrance designation should not be treated as simply an optional enclosure feature; it changes how the transfer switch integrates into the building's electrical service.
Why Choose the Kohler RDT 200A Service-Entrance ATS?
The Kohler Power RDT Series 240V 200A Automatic Transfer Switch with Service Entrance combines automatic generator transfer with a factory-installed normal-source disconnect. Its 200A capacity, 240V single-phase configuration, MPAC 500 controller, status indicators, load-management options, and corrosion-resistant aluminum enclosure make it well suited to residential and small-business standby power installations.
The RDT-CFNC-200ASEQS4 is particularly appropriate when a project requires a service-entrance-rated automatic transfer switch rather than a standard ATS. Its integrated service disconnect can simplify the electrical arrangement while providing automatic transfer between utility and generator power.
Model identification: The exact service-entrance model is RDT-CFNC-200ASEQS4. Kohler also offers a 200A RDT service-entrance configuration with a 42-space load center, model RDT-CFNC-200BSEQS3; that is a different product with substantially different dimensions and weight.
