Generac RXG16EZA1W 100A 1ph-120/240V Nema 1 Pre-wired Automatic Transfer Switch with 16-circuit Load Center Features:
Generac RXG16EZA1W 100A 1-Phase Automatic Transfer Switch Features:
The Generac RXG16EZA1W is a robust indoor solution for homeowners seeking essential power protection without dedicating an entire generator system to every circuit. With a 100-amp single-phase rating (120/240V), it includes a built-in 16-circuit load center. This lets you choose and power only the most critical circuits—think lighting, refrigeration, essential HVAC, and security—during outages, helping reduce generator size and installation costs while preserving vital functionality.
This model comes pre-wired with a two-foot whip to streamline connection to your main panel, saving installation time. The switch is housed in a NEMA 1 steel enclosure with a powder-coated finish—intended for indoor use in garages, basements, or utility rooms. The heavy-duty Generac contactor ensures reliable automatic switching, while the generator’s controller handles sensing, timing, and self-exercise to maintain readiness.
Open-transition switching is part of the design, meaning the utility input is disconnected before the generator power is applied, preventing source overlap for safer operation. With support for standard, tandem, GFCI, and AFCI breakers, the load center offers flexibility in configuring which circuits matter most. Backed by a 5-year limited warranty, the RXG16EZA1W combines compact design, essential circuit backup, and peace of mind.

Prewired Transfer...
Saving time and accuracy is most important when installing generator systems. Purchasing this pre-wired transfer switch does both. Installing this transfer switch allows time to focus on other aspects of a generator installation. Having a select-circuit transfer prewired with circuit breakers and branch circuit wiring made the installation more profitable. Investing a little more for this model, instead of a basic "non-wired" model, was well worth the added cost. Highly recommend this pre-wired transfer switch!
