Generac RTSN100J3 – Frequently Asked Questions

1) Can the Generac RTSN100J3 transfer switch be mounted outdoors next to the generator?
Yes. The RTSN100J3 is housed in an aluminum NEMA/UL type 3R enclosure with electrostatically applied and baked powder paint, which is the rating used for outdoor, rain-tight service. The aluminum shell also keeps corrosion down in coastal or humid installs, and it can go indoors just as well if your run is shorter that way.
2) Does the RTSN100J3 need a separate controller or timer board to run automatic transfer?
No separate control module is needed. On the RTSN100J3 the controller at the generator handles all the timing, sensing, exercise functions and the transfer command itself. The switch carries a heavy duty Generac contactor that is a UL and CUL recognized device. That means this switch is intended to be paired with a Generac standby unit that provides the control logic, not used as a standalone self-controlled switch.
3) How many air conditioners can a Generac RTSN100J3 smart transfer switch manage on generator power?
Using digital power management, the RTSN100J3 can shed and restore up to 4 individual HVAC loads that are 24 VAC controlled, with no extra hardware. Add smart management modules and you can manage up to 8 more loads on top of that. It cycles power on and off as loads demand, which is how you run a larger house or small commercial space off a generator that could not carry everything at once.
4) What size generator can I connect to the Generac RTSN100J3?
The RTSN100J3 is rated for a maximum generator input of 22,000 watts. Anything up to a 22 kW standby unit is within the switch rating; if you are specifying a larger genset, you need a bigger switch.
5) How much wall space do I need for the Generac RTSN100J3 automatic transfer switch?
Plan on a footprint of 21 inches high, 16 inches wide and 9 inches deep for the RTSN100J3 enclosure. It weighs 20 lbs empty, so a single installer can hang it, but anchor into studs or block and leave working clearance in front per your local code.
6) Is the Generac RTSN100J3 transfer switch approved for use in Canada?
Yes. The RTSN100J3 is both UL and CUL listed, and the contactor inside is a UL and CUL recognized device, so it is acceptable for Canadian installations as well as US ones. It is built in the United States.
7) Does the Generac RTSN100J3 come with installation instructions and mounting hardware?
Installation instructions ship in the box, and the switch itself is supplied as the transfer switch assembly. Conduit, fittings, conductors and the wall anchors suited to your mounting surface are supplied by the installing electrician. The finish is grey.
8) Does the Generac RTSN100J3 transfer switch carry a California Prop 65 warning?
No. The RTSN100J3 is not flagged as containing chemicals known to cause birth defects under California Prop 65, and there are no sale restrictions recorded on it. That matters for institutional and government procurement packages that require the disclosure up front.
