What Size Generator for 30 Amp RV? – Techniques And Tricks

If you are a regular traveler and enjoy going on camping trips with your RV, then you know the importance of having a generator. A generator is an important piece of equipment that provides power to your RV when there is no electrical hookup available. Without a generator, you would not be able to use any of the appliances or electronics in your RV.

While some RVs come with a built-in generator, most do not. This means that if you want to be able to use your RV while away from electrical hookups, you will need to purchase and own your generator. There are various generators on the market, and deciding which is the best for you.

What Is a 30 Amp Service for RV?


A 30-amp RV service is a power supply cable commonly used in RVs. It is a three-pronged plug that provides electricity to the RV. The amperage of the service is 30 amps, and the voltage is 120 volts. The cable is typically about 50 feet long and is made of heavy-duty copper wire.

Most RVs have a 30-amp service, which is the standard for most RV parks. However, some RVs may have a 50-amp service, which is more powerful and can provide electricity to more appliances.

The 30-amp RV service is connected to a power source, typically a power pole at an RV park. The other end of the cable is connected to the RV. The RV has a power panel that contains circuit breakers. The circuit breakers protect the RV from overloading the electrical system.

The 30-amp RV service is typically used to power the following:

  • Refrigerator
  • Microwave
  • Television
  • Lights
  • Water heater
  • Air conditioner

How to Choose a Generator For a 30 Amp RV?


If you are looking for a generator for your 30 Amp RV, you need to make sure that you choose one that is the right size. The size of the generator will be determined by the number of amps it can handle. You must make sure you choose a generator that can handle the number of amps your RV uses.

Power Output

The most important factor to consider when choosing a generator for a 30 Amp wattage is the power output. The power output is measured in watts, and you will need to know the wattage of your RV’s appliances and devices to determine the required generator size.

However, it is always best to choose a generator that can produce more power than you need. This will give you the flexibility to run more appliances and devices at the same time, and it will also help to prevent damage to your RV’s electrical system.

Fuel Type

When choosing a generator, you should also consider the fuel type. Generators can use different fuel types: gasoline, propane, or diesel. Each has its advantages and disadvantages. For example, gasoline generators are typically less expensive than diesel generators but more likely to produce harmful emissions.

Diesel generators are more expensive than gasoline generators but are much more efficient and produce fewer emissions. Propane generators are the most expensive option but the most efficient and produce the least emissions.

Noise Level

The noise level of the generator is also a very important factor. Some generators can be quite loud, which can be disruptive to your camping experience. If you are particularly sensitive to noise, you may want to choose a generator that has a low noise level.

In general, generators have a higher power output that will be louder than generators with lower power output. However, some high-quality generators are designed to run quietly.


The price of a generator for a 30 Amp RV can vary depending on the wattage and features of the generator. It is important to consider the needs of your RV when choosing a generator and how often the generator will be used.

How to Plug 30 Amp RV into the Generator?

Step 1

First, you need to find an available 30-amp circuit on the generator. Once you have found an available circuit, you need to connect the RV’s power cord. Make sure that the circuit breaker on the generator is in the “off” position before you make any connections.

Step 2

Next, you will need to connect a 30 Amp RV plug to the generator. To do this, you will need to use a 30-amp to 15-amp adapter. Once you have connected the adapter, you can plug the RV’s power cord into the adapter.

Step 3

Once you have plugged the RV’s power cord into the adapter, you can turn on the generator’s circuit breaker. This will provide power to the RV.

Frequently Asked Question

How Many Watts Does It Take to Run a 30 Amp RV?

It takes approximately 3600 watts to run a 30-amp RV. This is because the average RV uses about 120 volts of power and 30 amps of power. The formula for calculating watts is watts = volts x amps. Therefore, watts = 120 volts x 30 amps, which equals 3600 watts.

What Size 30 Amp Inverter Generator Do I Need for My RV?

When choosing an inverter generator for your RV, you must consider the wattage. A 30-amp inverter generator can provide up to 3,000 watts of power, which should be more than enough for most RVers. Some factors you may want to consider when choosing an inverter generator include the size and weight of the unit, the noise level, and the price.

What Is an Inverter Generator?

Inverter generators are a newer type of generator. They are becoming increasingly popular. They are similar to traditional generators in that they convert mechanical energy into electrical energy but differ in how they do this. Inverter generators have an inverter that changes the DC into AC, which is then used to power electrical devices.


If you’re going to be RVing at any time, you will need a generator. Whether you’re dry camping or boondocking, there are going to be times when you need to generate your electricity. A generator can provide the power you need to run your RV’s air conditioner, fridge, and other appliances. It can also recharge your RV’s batteries.

A 30 amp RV generator is a great investment for any RVer. It will give you the power you need when you need it, and it will give you peace of mind knowing that you’re prepared for any situation.
