Generac RXG16EZA3 100A Automatic Transfer Switch Features:
The Generac RXG16EZA3 is an ideal solution for homeowners who want essential circuit backup without having to invest in a full-house generator system. This 100-amp, single-phase automatic transfer switch includes a built-in 16-circuit load center, making it possible to support the most critical circuits during a power outage—think lights, refrigerator, security system, HVAC zones—directly from the switch. It’s perfect for setups where only part of the electrical load needs backup or when the main breaker panel is located outdoors.
Engineered with both durability and ease of use in mind, the RXG16EZA3 is housed in a NEMA 3R aluminum enclosure that resists rain, snow, and debris. Its electrostatically applied, baked powder-coat finish protects against corrosion, ensuring long-term performance in harsh conditions. It includes a heavy-duty Generac contactor, capable of handling frequent automatic switching, while system timing, voltage sensing, and self-exercise functions are handled directly by the generator controller.
Flexibility is built in: the 16 space breaker panel can be populated as needed, with the bottom four spaces accommodating tandem breakers for up to 24 circuits. It manages up to four HVAC loads without additional modules, helping keep overall system size and generator capacity more efficient while still preserving comfort. With its open-transition transfer type and a withstand rating designed to handle typical service stresses, it delivers safe, reliable switching for essential circuit backup systems.
Backed by Generac’s five-year limited warranty, the RXG16EZA3 gives homeowners peace of mind with both product reliability and protection—enabling essential circuit coverage exactly when it’s most needed.

The transfer switch appears to be of good quality and is functioning properly. Only issue, the outside of the transfer switch was significantly damaged during shipping. My fault for not checking before accepting delivery, just disappointed that my new transfer switch doesn't look new.
