When the power goes out, the transfer switch is the component that decides how your home shifts from utility power to generator power. If you're setting up a backup system around a Generac RXSW200A3, the automatic transfer switch you choose determines how smoothly that shift happens. The RASTP 200A Automatic Transfer Switch w/ Power Management is designed for this exact role, and this review looks at whether it fits your backup power plan.
Quick Verdict
The RASTP 200A Automatic Transfer Switch is a compatible alternative to the Generac RXSW200A3, not a genuine Generac original part. It's listed at USD 375.50 and combines a 200-amp whole-house rating with DPM technology that can manage up to four HVAC loads without extra hardware. The durable aluminum enclosure is suitable for indoor or outdoor installation, giving you flexibility in placement.
Who It Suits
This switch is a strong fit for homeowners with a single-phase generator and a Generac RXSW200A3 setup. It's particularly useful if you want to control multiple HVAC loads without adding separate load-management hardware. The indoor/outdoor rating also makes it adaptable to different placement needs, whether you're keeping it near the panel or outside by the generator.
What Stands Out
The DPM technology is the standout feature here. Being able to manage up to four HVAC loads without extra hardware simplifies the overall backup system and reduces the number of components you need to install. That's a concrete advantage for a home with multiple air-conditioning or heating zones.
Key Trade-Offs
The listed specification is for single-phase generators, so that's the parameter to consider. The listed model is a 200A unit, meaning the service rating is fixed at that size. Those are the main parameters to keep in mind when deciding if this is the right fit for your home.
RASTP 200A Automatic Transfer Switch w/ Power Management for Generac RXSW200A3
This is the product under review. At USD 375.50, you get an automatic transfer switch that brings whole-home switching and built-in load management to a Generac RXSW200A3-based backup system. The reason to choose it is that these capabilities come together in a single unit at a clear price. The limitation is that this isn't a genuine Generac original part, so the decision comes down to whether that matters to you.
Bottom Line
For a home backup system built around the Generac RXSW200A3, this RASTP switch delivers the automatic switching and load management you'd expect in this category. The final decision comes down to whether you're comfortable using a non-original transfer switch in that role.
