Generac 9932 150A 1ph-120/240V Service Rated Nema 3R Automatic Transfer Switch Features:
Generac 9932 150A Service-Rated Automatic Transfer Switch (1Ø, 120/240V)
The Generac 9932 150 Amp Automatic Transfer Switch is designed for applications that demand higher electrical capacity and dependable automatic power control. Built to integrate seamlessly with Generac standby generators equipped with Evolution™, Power Zone™ 200, or Power Zone™ 410 controllers, this unit continuously monitors utility power and initiates an automatic transfer to generator power during an outage. Once utility service is restored, it safely transitions back—keeping your system running without interruption.
With its increased 150-amp rating, this transfer switch is well-suited for larger homes, multi-system setups, or light commercial environments where additional load capacity is essential. As a service entrance rated switch, it includes a built-in utility service circuit breaker, allowing it to act as the primary disconnect for the electrical system. This integrated design helps reduce installation complexity while supporting compliance with electrical code requirements.
Operational precision is achieved through generator-controlled logic, where all timing, voltage sensing, and transfer functions are managed directly by the generator’s controller. This allows for coordinated system performance, including adjustable voltage thresholds, start delays, and retransfer timing. The open transition transfer mechanism ensures a safe and reliable break-before-make transfer between power sources, protecting both equipment and connected loads.
The enclosure is built for long-term durability, featuring a NEMA 3R aluminum housing with a corrosion-resistant powder-coated finish for outdoor or indoor installation. A fast-mount hanging system simplifies the installation process, reducing labor time, while the heavy-duty contactor is engineered for consistent operation over years of use. Manual operation capability adds service flexibility, and the unit is backed by a 5-year limited warranty for added confidence.
