200 Amp 3 Phase Service Entrance Rated Transfer Switch
Generac 120/208-Volt 200 Amp 3-Phase Automatic Transfer Switch — Service Entrance Rated
The Generac 120/208-Volt 200 Amp 3-Phase Automatic Transfer Switch is designed for commercial and industrial standby-power systems that require automatic switching between utility and generator power. Its 200-amp service rating, 120/208-volt three-phase configuration, and service-entrance-rated construction make it suitable for applications where the transfer equipment must serve as part of the facility's electrical service.
The switch automatically monitors the normal utility source and transfers the connected electrical load to a compatible standby generator when utility power is interrupted. Once normal power is restored, it can automatically return the load to the utility source.
Key Features
200-amp automatic transfer switch for high-capacity electrical service.
120/208-volt, three-phase configuration.
Service-entrance rated for installations requiring the transfer switch to function as service equipment when properly configured.
Automatically transfers connected loads between utility and standby generator power.
Automatically returns the load to utility power after normal service is restored.
Designed for use with compatible Generac standby generator systems.
Suitable for commercial, industrial, institutional, and other three-phase applications.
Provides a centralized interface between utility power, generator power, and the connected electrical load.
Automatic Transfer Operation
The transfer switch continuously monitors the normal utility power source.
During normal operation, the connected electrical load receives power from the utility. If the utility source is interrupted or falls outside the programmed acceptable conditions, the compatible standby generator can start.
After the generator reaches the appropriate operating conditions, the transfer switch moves the electrical load from the utility source to generator power.
When utility service returns and stabilizes, the transfer switch automatically transfers the load back to the normal utility source. The generator can then complete its normal shutdown and cool-down sequence.
This automatic operation helps maintain continuity of electrical service without requiring an operator to manually switch between power sources.
120/208-Volt Three-Phase Power
The 120/208V three-phase configuration is commonly used in commercial and institutional electrical systems.
Three-phase service can supply both:
120-volt line-to-neutral loads
208-volt line-to-line loads
This makes the configuration suitable for facilities with a combination of lighting, receptacles, HVAC equipment, motors, machinery, and other three-phase or single-phase electrical loads.
The generator, transfer switch, distribution equipment, and connected loads must all be correctly matched for the intended electrical configuration.
200-Amp Capacity
With a 200-amp rating, the transfer switch is designed for substantial electrical service requirements.
The 200-amp rating refers to the transfer switch's current capacity; it does not mean that the standby generator necessarily produces 200 amps. Generator capacity must be selected according to the facility's calculated electrical load and the equipment that needs to remain operational during an outage.
A qualified electrical professional should perform the appropriate load calculation before installation.
Service-Entrance Rated Design
A significant feature of this configuration is its service-entrance rating.
When installed and configured in accordance with the manufacturer's instructions and applicable electrical codes, service-entrance-rated transfer equipment can serve as part of the facility's service equipment. This can simplify certain standby-power installations by integrating service disconnect and transfer functions into the same system.
Service-entrance applications have specific requirements for grounding, bonding, overcurrent protection, disconnecting means, and utility connections. The exact installation must therefore follow the applicable electrical code and Generac's installation documentation.
Suitable for Commercial and Industrial Applications
The three-phase configuration makes this transfer switch particularly appropriate for facilities where three-phase electrical service is required.
Potential applications include:
Commercial buildings
Industrial facilities
Manufacturing operations
Warehouses
Institutional buildings
Retail facilities
Agricultural facilities
Mechanical and equipment installations
Other facilities requiring three-phase standby power
Generator Compatibility
The transfer switch is intended to work with a compatible Generac standby generator system.
Compatibility should be confirmed before installation because generator and transfer-switch combinations can differ in control systems, voltage configurations, phase arrangements, sensing requirements, and connection methods.
Always verify the exact transfer-switch model against the generator manufacturer's approved compatibility information.

Note: Exact specifications such as enclosure type, NEMA rating, short-circuit current rating, number of poles, neutral configuration, dimensions, weight, terminal capacity, control features, and specific generator compatibility depend on the exact Generac model number. These details should be confirmed from the manufacturer's documentation for the particular SKU before being published as fixed specifications.
How the Transfer Process Works
1. Normal Utility Power
The electrical load is supplied by the utility source while the standby generator remains available for backup operation.
2. Utility Failure
The transfer switch detects a loss or unacceptable condition in the normal power supply.
3. Generator Starts
The compatible standby generator receives the appropriate start command and begins producing electrical power.
4. Load Transfers
Once generator power meets the required conditions, the transfer switch moves the connected electrical load from utility power to generator power.
5. Utility Power Returns
When normal utility service is restored and stable, the transfer switch transfers the load back to the utility source.
6. Generator Shutdown
The generator completes its normal shutdown sequence after the electrical load has been returned to utility power.
Installation Considerations
Because this is a 200-amp, three-phase, service-entrance-rated transfer switch, installation should be performed by a qualified electrical professional familiar with commercial and standby-power systems.
Before installation, confirm:
The utility service is 120/208V three-phase.
The electrical service is compatible with the 200-amp rating.
The generator is correctly rated for the intended voltage and phase configuration.
The transfer switch is approved for the specific generator model.
Service-entrance requirements are satisfied.
Grounding and bonding are correctly configured.
Overcurrent protection and disconnecting means meet applicable requirements.
The installation complies with local electrical codes and manufacturer instructions.
Advantages for Standby Power Systems
A properly installed automatic transfer switch provides several important benefits:
Automatic source switching during utility interruptions.
Three-phase compatibility for commercial and industrial electrical systems.
200-amp capacity for substantial service requirements.
Service-entrance capability for appropriately designed installations.
Automatic return to utility power when normal service is restored.
Hands-free operation when paired with a compatible automatic standby generator.
Reliable Three-Phase Power Transfer
The Generac 120/208-Volt 200 Amp 3-Phase Automatic Transfer Switch, Service Entrance Rated, is designed for facilities that need dependable automatic switching between utility and standby generator power.
Its combination of 200-amp capacity, 120/208V three-phase operation, automatic transfer functionality, and service-entrance rating makes it a suitable component for properly engineered commercial, industrial, and institutional backup-power systems.
For a complete installation, the transfer switch should be selected based on the exact generator model, electrical service configuration, calculated facility load, service-equipment requirements, and applicable electrical codes.
