A 50-amp service is required by many contemporary RVs.
Unfortunately, in certain areas, the number of RV parks or resorts that provide this service is limited.
It’s essential to have a generator aboard that can offer enough power to your 50 amp RV, especially if you want to go to more remote areas with your RV.
Trying to figure out how many watts your RV uses at any particular moment might be difficult.
You’ll need to know about the electrical requirements for your major appliances, as well as the wall outlets where you plug in your cellphones and other electronic devices.
So, how big should a generator be for a 50-amp RV? The smallest generator possible For a 50 amp RV, I suggest going with a 4,000 watt generator.
Although the size of the generator you need will be determined by the ratings of your individual appliances as well as how many appliances you generally operate at once.
However, if you operate many appliances at the same time, your power demands may surpass that limit.
In the rest of this post, I’ll show you how to figure out what your RV’s electrical demands are so you can choose the best generator for 50 amp RV usage.
I’ll also go over four great portable generators that can handle 50 amps and address some of the most common concerns concerning 50 amp electrical service.
How to Select the Correct Generator Size for a 50 Amp RV
While 4,000 watts is a good starting point, there are other additional aspects to consider before deciding on the best generator for your requirements.
Choose one of the three power-outage scenarios below to help you choose the correct size generator for your 50 amp RV.
Let’s start with how to calculate your RV’s electrical requirements, and then look at a few additional considerations that may influence your ultimate buying choice.
#1. Calculating How Many Watts A 50 Amp RV Consumes
To comprehend your electrical requirements, we must first comprehend the maximum watts offered by a 50 amp service.
Because a 50 amp socket contains two 120-volt hot wires, a 50 amp service may provide a total of 12,000 watts.
This is referred to as a 120/240 split service by some.
In a 50 amp service RV, multiplying amps by volts is the formula for obtaining watts.
We can acquire a 6,000 watt rating by multiplying 50 amps by 120 volts.
However, since a 50 amp connection contains two hot wires, we may increase the power to a maximum of 12,00 watts.
However, we must exercise caution here since it is all too simple to conclude that the generator you choose should be capable of supplying 12,000 watts.
However, this isn’t always the case.
A generator with that much power may be quite costly, and it will supply much more electricity than you could ever need.
#2. Identifying Your Electrical Requirements
The starting and operating wattages for your different equipment must be carefully considered when determining your RV’s electrical demands.
The amount of electricity required to start an appliance is referred to as startup watts.
The amount of electricity required to keep an appliance operating is known as running watts.
Startup wattage is often greater than operating watts, as seen in the chart below from Honda.
|Starting wattage||200 to 600|
|Running wattage||200 to 600|
It’s worth noting, nevertheless, that the electrical ratings of the appliances may vary from those shown in this chart.
These are only estimates to help you figure out which appliances in your 50 amp RV will use the most electricity.
#3. Selecting an Appropriate Wattage For Your 50 Amp RV
Let’s have a look at how to pick adequate watts for your 50 amp RV’s individual requirements.
Let’s start by distinguishing between beginning and operating watts.
The appliances in your RV will use more electricity when they first turn on than they will after they’re up and running.
This implies that rather of concentrating on operating wattage, you should prioritize obtaining a generator that provides adequate starter wattage for your equipment.
Whether you have one or two air conditioning systems on your trailer will be the most important aspect in determining the demands of a 50 amp RV.
A 4,000-watt generator would most likely enough for a 50 amp RV with a single air conditioning unit.
However, adding a second 15,000 BTU A/C to your starting may significantly increase your initial power needs.
When figuring how much watts you’ll need in a generator, start by calculating the beginning wattage for your RV’s major appliances.
|RV Air Conditioner Size||7000 BTU|
|Starting wattage||1700 Watts|
|Running wattage||600 Watts|
|RV Air Conditioner Size||10,000 BTU|
|Starting wattage||2000 Watts|
|Running wattage||700 Watts|
|RV Air Conditioner Size||13,500 BTU|
|Starting wattage||2700 Watts|
|Running wattage||1250 Watts|
|RV Air Conditioner Size||15,000 BTU|
|Starting wattage||3500 Watts|
|Running wattage||1500 Watts|
The air conditioning unit (or units), refrigerator, and microwave are three of the most power-hungry equipment in a standard RV.
While it may be tempting to just tally up the starting wattages for all of your appliances and then purchase a generator that satisfies that rating, this is sometimes a way of splurging on a huge generator that you may not want.
To begin with, you probably aren’t (and shouldn’t be) operating all of your appliances at once.
Running just particular appliances at the same time is a terrific method to lower your total power demands while also extending the engine life of the generator you do choose.
It should also be mentioned that purchasing a generator with more watts than you need is simply a waste of money.
It’s pointless to invest in a 12,000-watt generator if you’re only using it to power equipment that need less than 6,000 watts.
At that time, you’ll have 6,000 watts of wasted energy, and your business will be inefficient overall.
What to Look For When Purchasing A 50 Amp RV Generator
#1. Weight of the Generator
Due to the bigger engines used in 50 amp RV generators, they weigh more than smaller versions.
This, by definition, makes them less portable.
Despite the fact that certain versions have wheels to assist you move them around, there will definitely be times when you’ll need to lift one of these generators.
So, before making a selection, make sure you’re okay with the weight of the generator you’re considering.
#2. Do You Have A Parallel Connection?
Certain generators may be connected to another generator of a similar brand to offer extra power for your RV.
While most 30 amp RVs may not need this extra power, those desiring a 50 amp service should take this into account.
Although these generators are designed to provide adequate initial watts for a normal RV air conditioning unit, operating your A/C, refrigerator, microwave, and fans while plugging several gadgets into wall outlets may overload your generator, causing it to fall short of your power requirements.
While we’ve already discussed why you shouldn’t operate all of your appliances at the same time, choosing a generator with parallel capabilities will enable you to enhance the amount of power delivered to your RV if the need arises.
#3. Type of Fuel
The majority of generators operate on gas, propane, or diesel fuel.
Some generators are referred to as ‘dual fuel’ generators because they can operate on a variety of fuel sources.
Because gasoline and propane are more easily accessible than diesel fuel, they are the most popular fuel combinations utilized by dual fuel generators.
It’s logical to choose a generator that uses the same sort of gasoline as your RV.
Diesel RVers, as well as RVers with gas-powered rigs, may simply stock up on that fuel type for their generator whenever they stop for gas.
The key benefit of a propane generator is the fuel’s long shelf life (when compared to gas and diesel fuel).
Access to a dependable propane refill station, on the other hand, will determine whether or not a propane generator is appropriate for you.
#4. Noise Emission
While many of these 50 amp RV generators claim to employ “Quiet Technology,” while they do create less noise than some of their predecessors, they aren’t fully quiet.
When they’re running, they’ll make between 55 and 70 decibels, and some only make the least noise when they’re in Eco-Mode, which is normally at 25 or 50 percent load.
As a result, don’t be shocked if the generator you buy generates more noise than indicated while it’s running at full capacity.
However, noise production is a vital consideration since you’ll want something that won’t keep you awake at night or irritate your RV park neighbors.
Having saying that, I wouldn’t prioritize this criteria above the ones listed above.

An RV’s power requirements are determined by the architecture of its electrical system.
I’ll address a few common questions regarding 50 amp service and how it varies from 30 amp service in this section.
What Does It Mean To Have A 50 Amp Service?
Multiplying amperage by voltage (amps x volts = watts) is the formula for computing the wattage of an electrical connection.
You obtain 6,000 watts by multiplying 50 amps by 120 volts (the rating for the hot wire on this sort of service).
50 amp plugs, on the other hand, feature two 120-volt hot wires.
This effectively gives you twice the power, or 12,000 watts of electrical capability.
This is known as a 120/240 split service in technical terminology.
Two 120-volt hot wires, a neutral, and a ground are included in a 50 amp service.
As a result, the overall wattage calculation looks more like this:
50 amps x (120 volts x 2) = 50 amps x 240 volts = 12,000 watts
What Is The Difference Between 50 Amp And 30 Amp Service?
The amount of hot wires in the connection is one of the key differences between a 50 amp and a 30 amp service.
A 50 amp service has two 120-volt hot wires, while a 30 amp service only has one.
When you add up the entire wattage for a 30 amp service, you’ll find that it delivers 3,600 watts (30 amps x 120 volts).
A 20 amp service is usually enough to run an air conditioner, microwave, refrigerator, television, and a few wall outlets, but a 50 amp service is far more powerful.
This is one of the reasons why many RVs with two air conditioners need a 50 amp connection.
Is it possible to plug a 50-amp RV into a 30-amp service?
Yes, a 50 amp RV may be plugged into a 30 amp service, however this is not advised.
In principle, using a dogbone electrical adaptor to connect a 50 amp RV into a 30 amp service is doable, but you’ll be restricted to 30 amp capacity, which may prevent you from using some 50 amp RV equipment.
I’ve personally experienced a lack of consistent service from my RV park’s electrical supply, and it’s not fun, particularly when you’re paying for energy you should be able to rely on.
Even if you just use it as a backup power source, a generator is required for a 50 amp RV.
In my lifetime, we’ve had to utilize our RV generator to supply backup power for our whole house on multiple occasions.
You’ll be pleased you bought that bigger portable generator to keep the lights on and the warmth running during a protracted power outage in your area!
