Furrion 50 Amp Automatic Transfer Switch F50-ATS
Best for: RV owners who want automatic, safe switching with robust protection. The Furrion F50-ATS features a built-in safe switch interlock system and supports automatic transfer between two 125/250 volt AC sources, such as a generator, shore power, or inverter. It uses a mechanical interlock to prevent both contactors from closing in parallel, reducing the risk of overvoltage on the output line. The UL 94 fireproof plastic casing adds a layer of safety for enclosed spaces. A 20–30 second delay ensures the generator reaches speed before load application.
Why selected: This model prioritizes safety and reliability in RV setups with multiple power sources. The interlock mechanism and delayed switching provide smoother transitions during power changes, which is particularly important for sensitive appliances and critical RV systems.
Limitations: The unit’s installation may require some wiring expertise, and it is designed specifically for certain input voltages. Confirm compatibility with your generator and shore power configuration.

Buying Guide: Choosing the Right 50 Amp RV Transfer Switch
- Power source compatibility: Confirm that the switch supports 125/250V AC or 120/240V configurations as required by your RV’s electrical system. The RV environment often uses shore power, generator, and inverter sources.
- Automatic vs. manual: Automatic transfer switches simplify operation by detecting power loss and switching sources without manual input. If you frequently rely on multiple power sources, automatic is advantageous.
- Safety features: Look for interlocks or mechanical interlocks to prevent parallel contactor operation, reducing overvoltage risk. A time-delay feature protects the generator from sudden load inrush.
- Durability and weather resistance: For exterior or semi-exposed mounts, choose galvanized, waterproof, or corrosion-resistant builds. Fire-rated housings offer extra safety in enclosed compartments.
- Installation complexity: Pre-wired options and clear wiring diagrams simplify installation. If you are not confident with electrical work, consider professional installation.
- Manufacturer support and compatibility: Verify that the unit is rated for RV power systems and that input/output configurations align with your current shore cord and generator setup.
