Generac RTSC800A3 – Frequently Asked Questions

1) Can the Generac RTSC800A3 transfer switch be mounted outdoors?
Yes. The RTSC800A3 comes in an aluminum NEMA/UL Type 3R enclosure with electrostatically applied, baked powder paint, so it is built for outdoor wall or pad mounting next to the generator or service entrance. The aluminum housing also keeps it from rusting out in coastal or wet locations, and the finish is grey.
2) What voltage and phase does the Generac RTSC800A3 automatic transfer switch work with?
It is a single-phase, 120/240-volt switch. If your service is three-phase, or 208V/480V, this is the wrong switch and you need a three-phase model instead. For a residential or light commercial 120/240V single-phase service backed by a Generac standby unit, it is the matching switch.
3) What size generator can the Generac RTSC800A3 transfer switch be used with?
It is designed for use with single-phase generators rated 150 kW and below. Pair it with a single-phase Generac standby set within that range; a three-phase set needs a different switch entirely.
4) Can this Generac transfer switch shed HVAC loads without adding extra hardware?
Yes. Digital Power Management is built in, so the switch manages up to four individual 24 VAC controlled HVAC loads with nothing else added. Add Generac Smart Management Modules and the count goes to eight managed loads. That is what lets a smaller generator carry a house with multiple condensers without oversizing the set.
5) How much wall space and clearance do I need for the Generac RTSC800A3 transfer switch?
Plan for an enclosure 52 inches high, 25 inches wide and 17 inches deep, plus your local working-clearance requirement in front. It weighs 130 lbs, so it is a two-person set and the mounting surface or pad has to carry that load.
6) Is the Generac RTSC800A3 transfer switch listed for use in an inspected installation?
It is UL Listed, and the heavy duty Generac contactor inside it is a cUL recognized device. The switch itself is cUL listed as well, which matters if the job is in Canada or an AHJ is asking for Canadian recognition on the equipment.
7) Does the Generac RTSC800A3 come with instructions and mounting hardware, or do I need to source those?
Installation instructions ship with the switch, and the installation hardware for the transfer switch is included. What is not included is the feeder conductors, conduit, lugs sized to your run, and the generator control wiring, so have those on the truck before the crew shows up.
8) Where is the Generac RTSC800A3 transfer switch made, and does it carry any shipping restrictions?
It is manufactured in the United States, which is the answer a government or institutional buyer usually needs for domestic-preference procurement. No restrictions are flagged on the item.
