Automatic Transfer Switches

Generac RXSW200A3 - Best for Whole House

The RXSW200A3 is Generac’s flagship automatic transfer switch. As a service-rated unit, it installs between your utility meter and main electrical panel, allowing whole-house backup without circuit selection.

Why It’s Our Top Pick:

This switch handles up to 200 amps—enough for most residential electrical services. When utility power fails, it automatically signals your Generac generator to start, waits for stable power, and transfers your home within seconds. When utility power returns, it transfers back and shuts down the generator.

Pros:

• True whole-house backup
• Completely automatic operation
• Outdoor rated installation
• Works even when you’re away
• Service entrance rated

Cons:

• Only works with Generac generators
• Requires standby generator purchase
• Higher cost
• Professional installation required

Generac RXSW100A3 - Best for Smaller Homes

The RXSW100A3 is the 100-amp version, ideal for homes with 100A electrical service or those using smaller Generac generators in the 10-16kW range.

Pros:

• Lower cost than 200A model
• Same automatic features
• Perfect for 100A homes

Cons:

• Limited to 100A service
• Won’t work for larger homes
