Generac RTSC600A3 – Frequently Asked Questions

1) Will the Generac RTSC600A3 work with a three-phase generator?
No. The RTSC600A3 is a single-phase, 120/240-volt transfer switch and it is built for use with single-phase generators rated 150 kW and below. If your set is three-phase, this is the wrong switch.
2) Can the Generac RTSC600A3 automatic transfer switch be mounted outdoors?
Yes. It comes in an aluminum NEMA/UL Type 3R enclosure with electrostatically applied, baked powder paint, which is a rain-tight rating for exterior wall or pad mounting. The aluminum body also avoids the rust issues a painted steel can has in coastal or wet locations.
3) How much wall space and clearance do I need to plan for a Generac RTSC600A3?
Plan the opening around 52 inches high, 25 inches wide and 17 inches deep. It also weighs 130 lbs, so on a wall mount you want blocking or a structural attachment, and realistically two people to set it.
4) Do I need extra load-shed modules to control air conditioning on a Generac RTSC600A3?
Not for the first four. Digital Power Management is built in, so the switch manages up to 4 individual 24 VAC controlled HVAC loads with no additional hardware. Add Smart Management Modules and the total goes to 8 managed loads, which is how you keep a large residence or small commercial building on a smaller generator without nuisance overload.
5) What size generator can the Generac RTSC600A3 handle?
The switch accepts up to 48,000 W of generator input and is specified for single-phase sets of 150 kW and below. For sizing on the utility side it is a 600 amp, 120/240 volt single-phase switch.
6) Is the Generac RTSC600A3 UL listed for permanent standby installations?
It is UL Listed, and the heavy duty Generac contactor inside is a cUL recognized device. The switch itself is also cUL listed, which matters if the job is in Canada.
7) Does the Generac RTSC600A3 ship with mounting hardware and instructions?
The RTSC600A3 ships as the transfer switch with its installation hardware and printed installation instructions. Conduit, conductors, lugs beyond what the switch carries, and any Smart Management Modules for load shedding are separate.
