Generac RTSW200J3 – Frequently Asked Questions
1) Can the Generac RTSW200J3 transfer switch be installed outdoors?
Yes. The RTSW200J3 is housed in an aluminum NEMA/UL Type 3R enclosure with electrostatically applied powder coating, so it is rated for outdoor wall mounting. Finish is grey.
2) Does the RTSW200J3 being "service rated" mean I can skip a separate main breaker?
Service rated is the point of the RTSW designation: the switch is suitable for use as service equipment, so it can be installed at the service entrance ahead of the panel instead of behind a separate main disconnect. It is 200 Amp, 120/240 V, three phase, and UL Listed.
3) Will the RTSW200J3 work on a single phase 120/240 service?
No. The RTSW200J3 is built for 120/240 volt three phase service at 200 amps. For a single phase residential or light commercial service you need the single phase version of the service rated RTSW switch, not this model.
4) What size generator can I connect to the Generac RTSW200J3?
Maximum generator input is 22,000 watts. Size the standby set at or below 22 kW on the 120/240 V three phase configuration; a larger generator needs a higher rated switch.
5) Does the RTSW200J3 come with its own controller and exercise timer?
No separate controller is needed or supplied with the switch. On Generac RTSW switches the controller at the generator handles all timing, utility sensing, weekly exercise, and the transfer commands, so the switch itself carries the heavy duty UL recognized contactor and the transfer mechanism only. That means the generator has to be a compatible Generac unit with that onboard controller.
6) How much wall space do I need for the RTSW200J3 enclosure?
Plan on 48 inches of height, 21.82 inches of width, and 10.06 inches of depth off the wall. It weighs 55 lbs, so one installer can hang it, but the 48 inch height means you need clear vertical run plus working clearance in front.
7) Is mounting hardware included with the RTSW200J3, or do I need to supply it?
Mounting hardware ships with the switch, and installation instructions are in the box. You still supply conduit, fittings, and conductors sized for the 200 amp service, plus the control wiring run to the generator.
8) Is the Generac RTSW200J3 made in the USA?
Country of origin is the United States, which matters if you are buying under a domestic sourcing preference on a government or institutional job.
9) What is the exact part number to order for the 200 amp service rated 3-phase Generac switch?
Order Generac RTSW200J3. That MPN is the 200 amp, 120/240 volt three phase, service rated automatic transfer switch in the NEMA 3R aluminum enclosure.
