Generac 9952 200A Automatic Transfer Switch Features:
The Generac 9952 200A Service-Rated Automatic Transfer Switch is built to deliver whole-home power reliability and code compliance. With its 200-amp rating and service-rated design, this transfer switch is capable of serving as the main disconnect equipment in many installations. It automatically detects utility power loss and transfers critical circuits to generator power without manual intervention, so your home stays powered when you need it most.
Engineered for durability, the 9952 is housed in a NEMA 3R aluminum enclosure, ensuring it can be installed outdoors or in sheltered indoor locations. Its service-rated configuration provides stronger internal components—such as rugged contactors and heavier gauge lugs—designed to handle higher electrical loads and frequent switching. The switch supports safe open-transition transfer between utility and generator power, ensuring clean separation that helps protect both your home wiring and generator.
In addition to its robust construction and high-capacity throughput, the 9952 includes weather-resistant finishes to guard against corrosion and environmental factors. Its compatibility with Generac standby generators means installation and control integration are straightforward. Backed by a solid warranty, it gives homeowners peace of mind that their electrical system is protected both during outages and under daily stress.
