Generac RXG16EZA3 – Frequently Asked Questions

1) Can the Generac RXG16EZA3 transfer switch be mounted outdoors next to the meter?
Yes. The RXG16EZA3 uses an aluminum NEMA 3R enclosure, which is the rain-tight rating for outdoor wall mounting alongside a meter socket or on an exterior wall. It measures 30.1 inches high by 13.5 inches wide by 6.91 inches deep, so allow that footprint plus working clearance in front. At 39 lbs it is a one-person hang onto properly anchored fasteners.
2) What size generator does this Generac 100 amp ATS support?
Maximum wattage through the switch is 16,000 W on single phase, so it suits standby units up to roughly that output. Oversizing the generator beyond 16 kW gains you nothing here because the switch caps the transferred load.
3) Can I use this transfer switch on a three-phase commercial panel?
No. The RXG16EZA3 is a single-phase unit only. Three-phase service in a small commercial building needs a three-phase transfer switch; this one is built for standard 120/240V single-phase residential and light commercial systems.
4) Do breakers come with the Generac RXG16EZA3 load center transfer switch?
No. Package contents are the transfer switch only. The 16 breaker spaces ship empty, so order the branch breakers, any whip or conduit, and wire separately to finish the job.
5) Is this Generac ATS UL listed for permit and inspection?
It carries UL, ETL, and CSA safety listings, which covers the listing requirement an AHJ will look for on a permanent standby installation in the US or Canada. Built in the United States.
6) How does a load center ATS differ from a service-rated whole-house transfer switch?
A load center style switch like the RXG16EZA3 doubles as the panel for the backed-up circuits: you relocate up to 16 branch circuits into it and only those transfer to generator power. A service-rated whole-house switch sits ahead of the main panel and transfers everything, then relies on load shedding to stay within generator capacity. The load center approach lets you fix backup priorities in hardware and keeps the generator sized to 16 kW or less.
7) Is this switch suitable for a multi-family or retail backup install, or is it residential only?
Both, within its rating. Generac lists it for residential backup, professional offices, retail, multi-unit properties, and light industrial work. The limits that decide it are 100 amps, 16,000 W, single phase, and 16 backed-up circuits. Anything beyond those needs a larger switch.
8) What is the Generac part number for the 16-circuit 100 amp NEMA 3R transfer switch?
Generac model and MPN RXG16EZA3. That is the 16-circuit, 100 amp, single-phase load center ATS in the aluminum NEMA 3R enclosure.
