Westinghouse 6500 Watt Dual Fuel: Transfer Switch Ready

Best for homeowners who want a compact dual-fuel option with ready transfer switch compatibility. Gasoline provides strong peak output, while propane offers longer run times in emergencies. It includes a 4.7-gallon tank with a fuel gauge and up to 14.5 hours at an appropriate load. It features a 120V duplex outlet, an RV 30A outlet, and a transfer switch ready 30A receptacle, all with rubber outlet covers for safety. Best for: homes needing reliable, switch-ready power without oversizing.
Caution: The unit’s longest runtimes occur at lighter loads; heavy air-conditioning loads may reduce run time. Minimal assembly is required after delivery, and you’ll want to verify local transfer switch compatibility before purchasing.
DuroStar DS13000MX: 13,000-Watt Dual Fuel

Choose this for maximum power in a dual-fuel package with a remote electric start. The 13,000-watt rating on both fuels provides ample capacity for whole-home backup and demanding loads. It supports a transfer switch connection and includes safety features like a CO detector to automatically shut down if dangerous fumes are detected. Best for: larger homes, workshops, or RVs that require robust, switch-ready power.
Limitation: It’s a heavier unit with a bigger footprint, so siting and transport require planning. Ensure your transfer switch and fuel availability align with expected usage.
Westinghouse 6600 Peak Watt: Compact Transfer Switch Ready

This model suits buyers who want a balance of portability and enough output for essential circuits. It provides 5300 running watts with 6600 peak watts, a 4.7-gallon tank, and a 30A transfer switch-ready receptacle. It’s easy to start with a recoil or electric option and includes safety features such as rubber-covered outlets. Best for: smaller homes or cabins needing reliable backup power with transfer-switch readiness.
Better for: users who value a lighter footprint while still needing enough power for critical appliances. Caution: Run time can vary with heavy loads, so plan load management accordingly.
WEN 5600-Watt: Transfer-Switch Ready

The WEN GN5600 is a cost-conscious option that still includes transfer-switch readiness and RV compatibility. It delivers 5600 starting watts and 4500 running watts, with a 4.3-gallon tank for up to about 12.5 hours at half load. It includes a wheel and handle kit for easier transport. Best for: budget-conscious buyers who still want reliable, move-to-mount power with transfer-switch compatibility.
Limitation: It may have fewer protective features than premium models, so consider adding CO monitoring or a dedicated transfer-switch installation by a professional if needed.
Westinghouse 12500 Dual Fuel: Remote Start Power

Ideal for large homes or heavy-duty remote power needs, this model offers 9500 running watts and 12500 peak watts on gasoline, plus 8500/11200 on propane.

Buying Guide: Transfer Switch Ready Generators
What to consider when selecting a transfer switch ready generator:
- Power needs: List essential circuits and appliances to determine running watts and peak loads. Heavy HVAC or water heaters may require higher output models.
- Fuel strategy: Dual-fuel and tri-fuel units offer flexibility during outages but may increase maintenance and operating costs.
- Transfer switch compatibility: Verify the receptacle type (L14-30R is common for 30A transfer switches) and ensure your switch supports the generator’s voltage and phase.
- Run time and fuel tank: Larger tanks extend runtime but increase size and weight. Match expected outage durations with tank capacity.
- Safety features: CO shutoff, automatic low-oil shutdown, and outlet covers improve safety during operation in enclosed spaces.
- Portability vs. permanence: Wheeled units are easier to move for seasonal use, while stationary setups may suit a fixed backup location.
- Installation considerations: Some models require professional wiring for transfer switches to ensure code compliance and safe operation.
