Generac RTSN100G3 – Frequently Asked Questions

1) Can the Generac RTSN100G3 transfer switch be mounted outdoors?
Yes. The RTSN100G3 comes in an aluminum NEMA/UL type 3R enclosure with electrostatically applied, baked powder paint, which is rated for outdoor wall mounting. The cabinet measures 21 inches high, 16 inches wide and 9 inches deep, and the whole unit weighs about 20 lbs, so a single installer can hang it.
2) Is the RTSN100G3 a single-phase or three-phase transfer switch?
Three-phase. The RTSN100G3 is a 120/208-volt three-phase automatic transfer switch rated 100 amps. If your service is single-phase 120/240, this is the wrong unit; you need a single-phase RTS model instead.
3) How big a generator can I run through a Generac RTSN100G3?
The switch accepts a maximum generator input of 22,000 W at 120/208 three-phase, with a 100 amp switch rating. Size the genset at or under that figure.
4) Does the transfer switch have its own controller, or does the generator run it?
The generator's controller does the work. On this Generac switch, all timing, sensing, exercise cycles and transfer commands are handled by the controller at the generator; the switch carries the heavy duty contactor that makes the transfer. That means it has to be paired with a compatible Generac standby unit rather than used as a standalone automatic switch.
5) Does the RTSN100G3 need extra hardware to shed HVAC loads?
No extra hardware for the first four. Using Generac's digital power management, the switch manages up to 4 individual 24 VAC controlled HVAC loads on its own, cycling power to appliances as needed. Add smart management modules and you can control up to 8 more loads.
6) Is the Generac RTSN100G3 listed for use in Canada?
It is both UL and CUL listed, and the Generac contactor inside it is a UL and CUL recognized device, so it can be specified on either side of the border.
7) What ships in the box with the RTSN100G3, and are instructions included?
You get the transfer switch itself as the included hardware, along with installation instructions. Conduit, conductors, breakers and any mounting anchors for your wall are a separate buy.
8) What is the exact Generac part number for the 100 amp 120/208 three-phase NEMA 3R transfer switch?
RTSN100G3. It is grey, built in the United States, and carries no sales restrictions or California Prop 65 birth defect chemical warning.
