Generac 9929 200A 1ph-120/240V Service Rated Nema 3R Automatic Transfer Switch Features:
Generac 9929 200A Service-Rated Automatic Transfer Switch (1Ø, 120/240V)
The Generac 9929 200 Amp Service-Rated Automatic Transfer Switch is built for whole-home and high-demand standby power systems that require maximum capacity and fully automated operation. Designed to work seamlessly with Generac generators equipped with Evolution™, Power Zone™ 200, and Power Zone™ 410 controllers, this switch continuously monitors incoming utility power and automatically transfers your electrical load to generator power during an outage. Once utility service is restored, it transitions back smoothly—keeping your home or business powered without interruption.
With its 200-amp capacity, this model is ideal for larger residences or commercial applications where full electrical system coverage is essential. As a service entrance rated transfer switch, it includes an integrated utility service circuit breaker, allowing it to serve as the primary disconnect for the electrical system. This built-in functionality simplifies installation, reduces the need for additional equipment, and supports compliance with modern electrical code requirements.
The Generac 9929 uses an open transition transfer design to ensure safe, reliable switching between power sources. All sensing, timing, and operational control functions are handled directly by the generator’s controller, creating a fully synchronized system. Adjustable parameters such as voltage thresholds, start delays, and retransfer timing allow for customized performance based on installation needs and load conditions.
Constructed for durability, the unit features a NEMA 3R aluminum enclosure with a corrosion-resistant powder-coated finish, making it suitable for both indoor and outdoor environments. The fast-mount hanging system streamlines installation, while the heavy-duty Generac contactor is engineered for long-term reliability. With manual operation capability and a 5-year limited warranty, this transfer switch provides a dependable, high-capacity solution for automatic standby power systems.
