What is the difference between 30 amp and 50 amp generator?

Just like the amperage differs, power output isn’t the same with both. A 50 amps generator surpasses the power output obtainable with the 30 amps unit in a near 3 – 1 ratio.

The benefit is that the generator could power several appliances simultaneously without you having to compromise.

Another difference between both amp generators is the number of prongs available on the plugs. With the 30 amps plug, you get three prongs representing the 120-volt wire, neutral and the earth. The 50 amps plug has four prongs, which sees the addition of another 120-volt wire to the fold.

What size generator do I need for 50 amps?

With the 50 amps generator, you have two 120-volt wires which can be combined to deliver the running power output of the generator.

To get a clear picture of how many watts a 50 amp generator should have, take a look at this simple maths:

50A x 120 volts x 2 = 12000 watts

Here, the 50A refers to the amp service involved; the 120 volts refers to the hot wire present; the 2 represents the number of 120 volts wire present.

A true 50 amp generator has wattage of around 12,000 watts.

The actual wattage of a generator ( 50 amp ) that you’ll need could be as low as 6000 watts, but this is going to depend on the appliances you intend to run on the generator.

Starting Output VS Rated Output 

If you’re concerned about a generator ( 50 amp ) meeting your power needs, you can’t ignore the power output, especially along the lines of its starting wattage and rated wattage.

While the latter could be considered more vital in the scheme of things, both help you to better understand your power usage.

When settling for a 50 amp generator, it’s crucial that your preferred unit has a starting power output that exceeds the combined sum of all your RV appliances.

Why is this important? Well, the peak wattage of every appliance is often higher than its running wattage due to the effect of inertia on the components.

If you’re going to run multiple devices on your generator, then you need to confirm the 50 amp unit can handle it. The generator’s starting power output is usually the easiest way to confirm this.

The running wattage of a generator could serve as a guide on the capacity of the unit.

If it’s able to support heavy duty appliances in your RV like air conditioners and water heaters, you should be able to tell through its running output.

You will need to calculate the total wattage of your appliances to get a clear picture of the power capacity of your ideal generator.

A 50 amps unit might be more powerful than its 30 amps counterpart, but there are different levels to that output – it’s your call on what your preferred 50 generator’s wattage should be.

An Exclusive Buying Guide

 ​Before buying a  generator ( 50 amp), there are a few things you need to take into consideration. Some of these factors include:

Noise level

While generators are known for their hefty power output, the noise generated by such units can be unpleasant.

The average 50 amp generator is capable of producing around 70db of sound when placed some feet away from you. You can’t be expecting a silent operation from such units. If that’s what you are looking for, you might have to put some space between the generator and your RV.


Generators, especially the 50 amp type can be heavy. This tends to affect the ease of carrying them around. Luckily, most manufacturers have found a way around such a problem as the units get equipped with wheels and handle, making it less difficult to transport generators.

You still have to confirm that the one you have your eyes on has this capability.

Dual fuel or single fuel

A 50 amp generator that’s capable of using either of two different fuel sources is always worth having. The flexibility associated with such an attribute is hands down desirable. But it might not be the last straw kind of feature, especially when the generator has other pitfalls.

You’ll have to decide if a generator that’s limited to a type of fuel is something you can live with.

Cold start

When getting a generator, a cold start capability is often not given as much thought as it deserves.

For a 50 amp generator to start on a single touch during a snowy night is not commonplace – electric start isn’t enough when the temperature drops to near-zero level.

If you have ever started a generator when it’s freezing, you will know the need for a cold start technology in your 50 amp unit.

Endeavor to add the cold start capability to the list of must-haves for your preferred 50 amps generator.


Buying a generator isn’t just about its power output. You want a generator that will stand the test of time.

And it’s easy to tell the models that can achieve this and those likely to breakdown after a few uses.

One of the ways to identify the units that can survive long-term use is the materials used.

If you find plastic parts on the generator, the chances are that it could disappoint you in the long run.

There’s also the need to pay attention to the brand behind the generator.

Manufacturers that have been known to deliver quality generators for decades won’t want to damage their reputation with any bad product lines.

Rather than produce poorly made generators, they make expensive quality units.

Generator Maintenance Tips

It is one thing to get a 50 amp generator for your RV, and it’s another to have it work efficiently. You have to maintain the generator if you intend to get the best service from it. Here are few tips towards keeping the generator in tiptop condition:

1. Replace the oil often

You have to change the oil in your generator as often as possible. Leaving old oil in the oil tank could affect the lubrication of the engine, which can be disastrous for your generator.

2. Clean the spark plug often.

With frequent use of your generator, there’s bound to be a build-up of debris on the spark plug. Using the tools included in your generator kit, you can remove and clean the spark plug.

3. Use the generator often.

Neglecting your generator when you’re not camping or boon docking with your RV can have severe consequences on the unit.

The engine could be burdened by faults arising from the coagulation of the fluids. This makes it essential to run the generator often with some load to ensure it functions at optimum capacity.

4. Keep an eye on the hour meter.

All 50 amp generators have an hour meter that keeps you informed on how long the generator has been working. You can also tell when it’s time to replace the oil as well as other maintenance requirements using the hour meter.

5. Confirm the battery is adequately charged

Most 50 amp generators have batteries for powering their electric start option. To avoid a situation where you have to use the recoil start, endeavor to charge the battery often.

However, some generators possess inbuilt mechanisms that charge the battery when the generator is running. You’ll have to confirm yours belong to this category.
