What Size Generator for 50 Amp RV? The Right Way To Go About It

As an RV owner, you know your vehicle is a home away from home. And just like your home, you need a reliable power source to keep things running smoothly. That’s why a good generator is an important investment for any RV owner.

A generator can provide the power you need to run your RV’s appliances, lights, and other electronics. It can also charge your RV’s batteries, so you’ll always have a backup power source in an emergency.

What Is a 50 Amp Service for RV?


A 50 Amp service for RV is a type of electrical service designed for recreational vehicles. This service provides a higher power level than a standard 30 Amp service. It is typically used for RVs with more electrical needs, such as air conditioners, microwaves, and other appliances.

A 50 Amp service typically uses two 50 Amp breakers in the main electrical panel. The two breakers are connected to two hot, typically red and black wires. The two hot wires are then connected to the 50 Amp receptacle, which is typically located on the outside of the RV.

An RV owner must have a 50 Amp generator wire size that is long enough to reach from the RV to the 50 Amp receptacle. The cord will typically have a male plug on one end that will fit into the receptacle and a female connector on the other that will connect to the RV.

Once the cord is connected, the RV owner must turn on the two 50 Amp breakers in the main electrical panel. After the breakers are turned on, the RV owner can plug in the RV and begin using the higher power level provided by the 50 Amp service.

How to Choose a Generator for a 50 Amp RV?


When shopping for a generator for your 50 Amp RV, it is important to consider what you will use it for. If you plan on using it for long periods, you will need a generator capable of handling the load. There are many different generators on the market, so it is important to do your research before making a purchase.


The first factor is the size of the generator. You will need to choose a large enough generator to handle the load you plan on putting on it. The size is measured in cubic feet (cu. ft.). The larger the generator, the more weight it will be. Some people prefer a smaller generator because it is easier to transport.

Fuel Type

The second is the fuel type. The most common fuel types are gasoline, propane, and diesel. Gasoline generators are the most affordable but are also the least efficient and have the shortest run time. Propane generators are more expensive but more efficient and have a longer run time. Diesel generators are the most expensive but most efficient and have the longest run time.

Noise Level

The noise level is the third factor. Some generators are very quiet, while others can be quite loud. If you plan on using the generator for long periods, you will want to choose one that is not too loud.

The fourth factor to consider is the price. Generators can range in price from a few hundred to several thousand dollars. Before making a purchase, you must decide how much you are willing to spend on a generator.


The fifth and final factor to consider is the warranty. Most generators come with a warranty, but you will want to ensure that the warranty is for the time you plan to use the generator. By taking the time to consider all of these factors, you will be able to find the best generator for your 50 Amp RV.

How to Plug a Generator For a 50 Amp RV?

Step 1

Find the generator output power in watts. This is usually listed on the generator and will be something like “5000 watts.”

Step 2

Find the RV power requirements in amps. This should be listed in the RV’s owner’s manual.

Step 3

Divide the generator output power by the RV power requirements to find the number of amps the generator will supply.

Step 4

Plug the RV into the generator using a heavy-duty extension cord. Be sure to use a cord rated for the generator’s amperage. In this example, a 50-amp generator would require a 10-gauge extension cord.

Step 5

Start the generator and let it warm up for a few minutes.

Step 6

Turn on the RV’s power switch. This will usually be located near the main electrical panel.

Step 7

Monitor the RV’s electrical system. The RV’s electrical system will charge the batteries and power the lights and appliances if everything works properly. If the RV’s electrical system is not working properly, turn off the power switch and unplug the RV from the generator.
