Generac RXG42SHA1 – Frequently Asked Questions

1) Can I use the Generac RXG42SHA1 as the service entrance disconnect, or do I still need a separate main panel?
It is service equipment rated, so it can land the utility feed directly. The RXG42SHA1 combines a 200 amp service entrance rated automatic transfer switch with an integrated 42 circuit load center in one enclosure, and it carries UL Listings for service equipment and consumer safety under UL67 and UL1008. That lets you replace the existing main panel and ATS with a single unit rather than feeding a downstream sub panel.
2) Which brand of circuit breakers fit the Generac RXG42SHA1 load center?
The integrated load center takes 1 inch standard, GFCI, AFCI, or tandem breakers from Siemens, Murray, Eaton, and Square D. That means you can often reuse the breakers out of the panel you are removing instead of buying a full set, and there is no Generac-branded breaker requirement.
3) Will the Generac RXG42SHA1 work with my air conditioner without adding a load shed kit?
No extra hardware needed. Digital Power Management is built into the switch and it will manage up to four individual HVAC loads, provided those units are 24 VAC controlled, which covers standard residential thermostat-controlled condensers. The switch sheds and restores them so a smaller generator can carry the house.
4) Can the Generac RXG42SHA1 transfer switch be mounted outside on the side of the house?
Indoor only. It ships in a steel NEMA 1 enclosure, which is a general purpose indoor rating with no protection against rain or windblown water. Put it in a basement, garage, or utility room. For an exterior wall you need a NEMA 3R rated service entrance switch instead.
5) Will the Generac RXG42SHA1 work with any standby generator?
It is built for single phase Generac standby units running the Evolution or Nexus controller. Those controllers carry the two-wire start and Digital Power Management communication the switch relies on. If your unit uses a different controller platform, or you are running three phase, this is not the switch for that install.
6) Is the Generac RXG42SHA1 approved for installation in Canada?
No. This version is UL Listed but not CUL, and it carries no CSA listing, so it will not pass a Canadian electrical inspection. Canadian jobs need the CUL listed version of the service entrance switch.
7) How big a generator can the Generac RXG42SHA1 handle?
The switch is rated to 200 amps and 22,000 watts maximum, which puts it in line with a 22 kW single phase air-cooled standby unit. Sizing above that requires a higher capacity switch.
8) What actually comes in the box with the Generac RXG42SHA1, and what do I still have to buy?
The carton holds the transfer switch and the integrated load center as one assembly. Branch circuit breakers, the main breaker sizing to your service, conduit, and the control wiring run to the generator are all separate. Budget for a full set of 1 inch breakers unless you are reusing Siemens, Murray, Eaton, or Square D breakers from the panel you are pulling out.
9) Is the Generac RXG42SHA1 made in the USA?
Country of origin is the United States, which is the line procurement officers on government and institutional jobs usually need on the submittal.
