A heavy-duty 50 amp generator provides higher power output for running an air conditioner without overloading issues.

Several customers have used a 30 amp generator to run a modest central air conditioner. That is why an electrician should examine your home’s electrical use as well as the readings from your HVAC equipment.

Reading the labels on your gadgets to estimate your electrical use is like taking your temperature with both the back of your hand. Not precise. 

Consult your electrician about putting a hard start relay for your central air conditioner. Installing this hard start relay to free up some power from your generator is less than $20, and it will also save you money on your electric bill.

Running a 30 amp generator might be more appealing due to fuel efficiency and propane (LPG) fuel storage limitations.

The fuel consumption of a 30 amp generator is nearly half that of a 50 amp generator. When there is a power outage and limited fuel, a smaller generator would run longer and use less fuel than a larger generator.

Someone with natural gas supply lines, on the other hand, is unconcerned about running out of fuel.

What Is a Generator?

50 vs 30 amp generator

A generator is a device that transforms motive force into electricity generation to be used in an external circuit to produce electricity.

Any machine that transforms mechanical energy into electrical energy for distribution and transmission via power lines to household, commercial, and industrial users is an electric generator, sometimes known as a dynamo. Automobiles, aircraft, ferries, and trains all require electrical power generated by generators.

Electricity is measured in amps. It is a measurement of how much energy an appliance or equipment consumes to function.

Depending on its size, a generator delivers a specific number of amps. A 30 amp generator may provide 30 amps of power in this situation.

A 30 amp generator provides enough power that can power up multiple devices irrespective of whether you are indoor or outdoor, on camping, traveling or tailgating.

You can also opt for powering your RV devices while on a long road trip. Your power demands will determine which type of generator is ideal for you.

If you’re considering a high-quality generator for tailgating, road trips, or campsites, the compact and lightweight units are a great option.

Their compact size makes them even fit your vehicle and provide power wherever you require.

What Size Generator Do I Need for a 30?

Basically it depends on your need if you want to use some high voltage appliance then 3600 watt or above power are enough otherwise 1,500 to 2,000 watt generator are the best option for a 30 amp

You can use the maximum size of the generator 3,600 watts for a 30 amp, this will be good enough for an RV and for a house if you plan to use some high voltage devices. various types of brands offer that power on 30 amp with portable generators including dual or single fuel consumption brands like be Honda, Craftsman and more.

As per new innovation on HVAC companies also improve noise and make them more quiet as possible.

if you use 3,600 watt generator or above that require some power management in especially when your are running high powered electronics appliance such as hair dryers, air conditioners and heaters; you can use that thing as making schedule.

because if you use on single time high power appliances can cause overload because the high consumption capacity of high load appliance are 15 or 20 amp if the use on single time  trip the circuit or may cause any other.

If your program ignores high powered electric products then you need a smaller generator. 2000 watt generators are good enough for RVs.

That type of generator not only produces low power as well as provides other capabilities such as small size make it portable, small engine produce low noise that make it quieter and you can carry it anywhere.

50 Amp Generator

No products found.

RV generators, camping generators, emergency generators, building sites, and other applications frequently use portable generators with 50 amps.

They are normally powered by gas or a mix of gas and propane, with diesel engines being used in certain larger industrial or commercial models.

A 50A generator unit can provide you with 8 to 12 hours of backup power when operating heavy appliances, in addition to having a great quantity of power.

Consequently, even if you use a lot of electricity, a power loss or a large-scale blackout will not leave you without power.

Specs Comparison

Size And Power Outage

The size and capacity of the generator you’ll require are determined by how much electricity you’ll need in an emergency.

A 30 amp generator will be enough if you only need to power your refrigerator, a few small appliances, and a few lights.

However, if you want to run your washing machine, dryer, refrigerator or freezer, air conditioner or heater, and water heater, you’ll need a generator with at least 200 amps.

It’s also vital to consider the weight of your generator, especially if you’ll be utilizing it for recreational reasons.

Furthermore, the larger the generator, the more fuel it consumes over time. When it comes to fuel, generator fuel is also a crucial consideration.

Some generators run on gas, propane, diesel, and dual fuel. Consider tank size, shelf life, emissions, and fuel storage requirements while making your decision.

Watt Power

Your panel should have at least one or two unused breaker slots for the back feed breaker approach to work.

You’ll need a circuit breaker that thus matches your generator’s amperage and the service panel’s brand. For generators up to 8,000 watts, a 30-amp breaker is generally used, whereas, for generators between 8,500 and 15,000 watts, a 50-amp breaker is commonly used.

Two 120 volt hit wires are included in most 50 amp services. So 12000 watts is 50 amps multiplied by 120 volts times by watts.

50 amp generator

Normally, a generator of at least 3,000 watts is necessary. You won’t be able to go over 3,600 watts.

It would help if you choose a generator with a power rating of 3,600 watts or above to ensure that you have enough power in various situations.

Charging Difference

If you’re off the grid and therefore need to charge your batteries when the sun isn’t shining, such as in the winter, a 30 amp generator will suffice.

When the sun isn’t shining brightly enough, use the charger or battery bank to power the well, pressurize the residence, run the refrigerator, and charge our devices.

If you do not intend to use the central air conditioning but do not have central air, a 30 amp generator would most likely suffice to power your house.

Because the 30A Charger uses roughly 350 watts, and your AC uses 1250 surge watts, you should be good at using both simultaneously.

Surge wattage would indeed be 500 to 600 watts more if operating at 1250. For a brief length of time, max out your 2000 watt generator or trip it’s breaker.

However, if the AC turns on until the Charger is on, the Charger will most likely restart as well.


Even if someone possessed a 10,000-watt generator, they are unlikely to require more than the 7,200-watt capacity of a 30-amp system.

Even 8,000w generators are unlikely to charge a 30A system fully. Most people in this area use natural gas for everything.

On the other hand, those using electric stoves performed quite well with 5,500w generators throughout extended storms.

Some of your natural gas clients may have one significant electric device, such as a water heater, dryer, or electric stove.

Perhaps a good pump. In the majority of such circumstances, a 30A will suffice. However, if you have two or more of them, you should consider your entire load and if a 50A is required.

In a large family RV, a 50 amp generator is a fantastic addition in a large family RV.

These generators with 50 Amp outlets are also useful in various other situations where maximum power from a portable generator is required, such as ranches and huge building sites.

Which One To Go With

A whole-house generator is required if you wish to power your entire home during a power outage.

On the other hand, if you only need enough power to run your household appliances, a 30 or 50 amp generator would be a good option.

A 50-amp service has much more wattage than a 30-amp service. It can supply up to three times the wattage of a 30-amp service.

In comparison to 3,600 watts, this indicates a maximum of 12,000 watts. As a result, you’ll be able to operate a lot of additional appliances at once.

In a 50-amp service, the plugs are also different. 50 amp connectors have four prongs, whereas 30 amp plugs have three.

30 amp generator

30-amp service is a standard 120-volt RV service that provides 3,600 watts of power. Three-prong connectors and one specialized 30 amp breaker are used for the service.

Some 30 amp and 50 amp generators additionally have a labeled oil light, a battery recharge indication, a series of circuit breakers, and a voltmeter, among other convenience and safety features.


Because of its mobility and adaptability, a 30 amp generator is an ideal choice. Your electrical requirements will determine the size of the generator you need.

You’ll overload it if you buy one that’s too tiny, forcing it to give more power than it can manage. The generator will likely shut down or overheat if this happens.

Consequently, not only will the generator be fried, but so will your special appliances. If you purchase a generator that is too large, you will be overpaying for both the unit and the operation cost.50 amp and 30 amp unit outlets are always an excellent choice. The built in durable generators are typically dependable workhorses that are opted to power up construction site tools, ranches, fields, huge RVs, buses, and even your household appliances and devices.
