Southwire Surge Guard Automatic Transfer Switch with RV Power Protection 40350RVC3 50 Amp

Get complete, automatic electrical protection for your RV with the SouthWire Surge Guard 50 Amp Automatic Transfer Switch with RV Power Protection (Model 40350RVC3). This unit does double duty — seamlessly switching between shore power and generator power while simultaneously guarding your entire rig, bumper to bumper, against the faulty park power that damages so many RV electrical systems.

Automatic Transfer Between Power Sources

The 40350RVC3 automatically transfers to whichever power source is energized — shore power or generator — with no manual switching, plugs, or cords to handle. When both sources are available, the system follows a smart priority sequence:

• Generator dominates after a 30-second delay when both are present
• Shore power reactivates after a 2-second delay once the generator is shut down

These built-in delays protect your equipment from the rapid, jarring power transitions that can damage sensitive electronics and appliances.

Bumper-to-Bumper Power Protection

Beyond simple transfer switching, the 40350RVC3 provides total electrical protection, shielding your RV from the faulty pedestal power, wiring problems, and voltage issues common at campgrounds. It's the kind of all-in-one safeguard that protects your investment every time you plug in.
