Generac RXGW20SHA3 – Frequently Asked Questions

1) Will the Generac RXGW20SHA3 transfer switch handle a 200 amp service?
The RXGW20SHA3 is a 200 amp automatic transfer switch rated at 240 V, so it sits on a standard 200 amp single phase residential or light commercial service. It is a whole-house style switch with the load center built in, not a partial-load switch that only backs up a handful of circuits.
2) How much wall space do I need for the Generac RXGW20SHA3 transfer switch?
Plan for a unit measuring 38.5 inches high, 17.5 inches wide and 8 inches deep, weighing 49 lbs. That depth matters on a tight side yard or in a utility closet, and at 49 lbs it is a two-person set on the wall if you want it held plumb while you anchor it.
3) Can the Generac RXGW20SHA3 be mounted outdoors next to the meter?
Yes. The switch is housed in an aluminum Type 3R enclosure, which is the rain-tight rating used for outdoor service equipment, so it can go on an exterior wall beside the meter or the generator. Aluminum also means no rust bleed on a coastal or wet site. Finish is bisque.
4) How many circuits can I run through the Generac RXGW20SHA3 load center?
The integrated load center has 20 spaces. Fill those with full-size breakers and you get 20 circuits; use tandem breakers and it supports up to 40 individual circuits. It takes 1 inch standard, GFCI, AFCI, or tandem breakers, so AFCI bedroom circuits and GFCI kitchen and bath circuits land in the same panel rather than needing a separate one.
5) Do I need a separate load management module to run two air conditioners on a Generac RXGW20SHA3?
No extra hardware. The smart A/C module is integrated and manages up to four individual HVAC loads on its own. For a multi-family building or a house with several condensers, that shedding is what keeps a smaller generator from tripping on compressor inrush, and it saves buying and mounting separate load-shed modules.
6) Does the Generac RXGW20SHA3 switch have its own controller, or does the generator run the transfer?
The generator's controller does the work. It handles all timing, sensing, exercise functions, and the transfer commands, so there is no second control board to program at the switch. Practically, that means your startup and any delay adjustments happen at the generator, not on the wall by the meter.
7) Is the RXGW20SHA3 the same part as the RXGW20ASHA3?
They are the same 200 amp service-rated switch with the 20 to 40 circuit load center, and the orderable part number is RXGW20SHA3. If a quote or an existing install references RXGW20ASHA3, that is the part to supply.
