If you have a 50-amp RV but only a 30-amp generator, the L14-30P to 14-50R adapter allows you to connect the two. This is useful when you need to power a larger RV with a generator that doesn’t have a 50-amp output.

NEMA L5-30P to TT-30R Generator RV Adapter

The L5-30P to TT-30R adapter is used to convert a smaller 30-amp locking generator plug to fit a standard 30-amp RV outlet. This type of adapter is handy for smaller generators that have a different locking mechanism.

NEMA L5-30P to 14-50R Generator RV Adapter

This adapter is essential for connecting a 30-amp generator with a locking plug to a 50-amp RV. It ensures that even with a lower-capacity generator, you can still power your larger RV, albeit with limitations on the number of appliances you can run simultaneously.

NEMA L5-30P to L14-30R Generator RV Adapter

The L5-30P to L14-30R adapter connects a smaller 30-amp generator to a larger 30-amp receptacle. This is useful when dealing with different locking mechanisms between your generator and RV.

Additional Type:

  • 14-50P to TT-30R Generator RV Adapter: For using a 50-amp generator outlet (14-50P) with a 30-amp RV receptacle (TT-30R).
  • 6-50P to TT-30R Generator RV Adapter: Converts a 50-amp, 240-volt generator plug (6-50P) for use with a 30-amp RV receptacle (TT-30R).

It's important to note that the specific adapter you need will depend on the plug types of your RV and generator. Always ensure compatibility before making a purchase.

What Are the Differences Between 30 amp and 50 amp RV Generator Adapters?

Amperage Capacity

The main difference between 30-amp and 50-amp adapters is the amount of power they can handle. A 30-amp adapter can support up to 3,600 watts, while a 50-amp adapter can handle up to 12,000 watts. This makes 50-amp adapters more suitable for larger RVs with more appliances, providing the power needed for multiple devices to run simultaneously.

Tips: The power of a simple power adapter can be calculated by the following formula: Power (Wattage) = Voltage (Voltage) x Current (Amp)


It’s crucial to match the adapter to your RV’s power requirements. If your RV is equipped with a 50-amp system, using a 30-amp adapter will limit the power available, potentially preventing you from running multiple appliances at the same time. Conversely, using a 50-amp adapter for a 30-amp RV could result in an overload.

Cable Gauge and Thickness

Thicker cables are used in 50-amp adapters to handle the higher current flow without overheating or causing a voltage drop. This ensures that the power is delivered efficiently and safely to your RV. Thinner cables in a 30-amp adapter might not be suitable for the demands of a 50-amp system, leading to potential safety hazards.

Socket and Plug Configurations

The configurations of the plugs and sockets are different for 30-amp and 50-amp systems to prevent incorrect connections. These configurations include safety features that protect both your RV and generator from damage due to incorrect connections. For instance, a 30-amp plug will not fit into a 50-amp socket, ensuring you use the correct adapter for your setup.


When choosing between a 30-amp or 50-amp RV generator adapter, it's crucial to consider your RV's power requirements, the generator's output capacity, and the specific plug types involved. Selecting the appropriate adapter ensures safe and efficient power delivery, optimizing your RV experience.
