Generac RXSW150A3 – Frequently Asked Questions

1) Will the Generac RXSW150A3 work with any standby generator, or only certain Generac models?
The RXSW150A3 is built for single-phase Generac generators running an Evolution or Nexus controller. If your unit uses a different controller or is three-phase, this switch is the wrong match. It is a 120/240 volt single-phase, service rated switch, so it also has to land on a single-phase service.
2) Can the RXSW150A3 be mounted outdoors next to the generator?
Yes. The enclosure is aluminum, NEMA/UL type 3R, rated for indoor or outdoor use, with electrostatically applied and baked powder paint for added corrosion protection. That makes it suitable for an exterior wall near the meter or the generator pad.
3) Service rated versus a standard transfer switch, which do I need?
Service rated means the switch can be installed as the service disconnect, taking the utility feed directly rather than sitting downstream of an existing main panel. That is what the RXSW150A3 is: a 150 amp service rated, whole-house switch. If your main breaker panel is staying as the service disconnect and you only want to back up selected circuits, a non-service-rated switch downstream of the panel is the simpler install.
4) Do I need separate load shed modules for the air conditioners with this switch?
No extra hardware is needed for up to 4 individual HVAC loads. Generac's digital power technology puts load management on the same board as the transfer switch hardware, so the switch handles the A/C shedding itself. You can still add a Smart Management Module if you want to manage additional loads beyond those four.
5) Is the Generac RXSW150A3 UL listed for permanent installation, and will it pass inspection?
It is a UL Listed transfer switch and also carries an ETL safety listing. The enclosure is NEMA/UL type 3R. There is no CSA listing on this one, which matters if you are installing in Canada under a CSA requirement.
6) What wall space do I need to plan for a Generac 150 amp smart switch?
Allow for a cabinet measuring 31 inches high, 15 inches wide and 8 inches deep. It weighs 30 lbs on its own and 39 lbs as shipped, so it is a one-person hang on a solid wall, though service rated gear usually wants to sit right beside the meter.
7) What happens to my loads if the generator starts to overload during an outage?
The smart A/C module watches generator frequency. If frequency drops, which signals an overload, it sheds the connected loads to keep the generator running instead of letting it stall or trip. Loads are reconnected as capacity comes back.
8) How large a generator can the 150 amp smart switch handle?
Rated to 22,000 watts at 120/240 volt single phase, which covers Generac air-cooled home standby units up through the 22 kW class. Anything larger, or any three-phase set, needs a different switch.
9) What comes in the box with the RXSW150A3, and what do I still have to buy?
The carton holds the transfer switch only. Conduit, fittings, service entrance conductors, control wiring between switch and generator, and any mounting hardware for your wall type are all separate. Order part number RXSW150A3 to get this configuration.
10) Does this Generac transfer switch need a Prop 65 warning, and where is it made?
No Prop 65 birth-defect chemical warning applies, and there are no shipping restrictions flagged on it. Country of origin is the United States, which is useful if you are filling out a Buy American or domestic-content line on a public project submittal.
