A 30 amp generator can typically run at least a refrigerator or electric grill. However, you want to keep in mind that 30 amp generators can still vary a lot in terms of the watts they produce.

In turn, only knowing that a generator offers 30 amps is typically not enough to say much.

One thing you can say is that bigger electrical devices like strong air conditioning systems sometimes require more than 30 amps.

Besides that, you want to find out how many watts your 30 amp generator can run and how many watts the devices you intend to power need.

For example, a 30 amp generator with 2300 continuous watts would only be able to run a coffee maker and electric grill.

Stronger 30 amp generators with 5000+ continuous watts could power devices like an electric oven, a 2-ton AC, or a 2 HP well pump.

## How many watts is a 30 amp generator?

A 30 amp generator does not have a standard number of watts. The generators in this category can still vary a lot in this area.

Your first reaction could be to turn to the Watts = Amps x Volts formula.

However, there are plenty of generator examples where an outlet can offer 30 amps or 120 volts but the machine is not strong enough to provide 3600 continuous watts.

In simpler words, just knowing that a generator can provide 30 amps does not say anything about how many watts the machine offers.

More specifically, there are 30 amp generators that only offer 2000 running watts but also 50 amp generators that also have 240 volt 30 amp outlets that can run 7200 watts (and more if you use multiple generator outlets).

### How many watts do you need to run 30 amps?

To run 30 amps at 120 volts you need at least 3600 watts. To run 30 amps at 240 volts you need at least 7200 watts.

You get these results from the Watts = Amps x Volts formula.

As an example, let’s say you want to use one 30 amp outlet with 120 volts of electric potential.

In that case, you would need at least 3600 watts to run these 30 amps.

With calculations like these, you do want to keep in mind there is typically a certain drop-off in watts through extension cords.

Additionally, when you start running multiple 30 amp receptacles to their full potential, your generator will need more watts.

## What devices can you run on a 30 amp generator?

A standard 30 amp generator will typically be able to run a refrigerator, microwave, certain RV air conditioners, or certain electric grills.

For these devices, your 30 amp generator needs at least 3000 running watts which is relatively common.

Keep in mind that many 30 amp generators will not allow you to run all of these devices at the same time.

For 30 amp generators, the range of devices is even wider than what 50 amp generators can run. There are very strong generators with “only” 30 amp outlets.

The actual watt ranges of 30 amp generators can vary from 1800 running watts to 9000+ running watts too.

As you can expect, this also means many differences in what devices these models can run.

### What is the 30 amp plug on a generator for?

The 30 amp plug on a generator is for powering strong devices, connecting to RVs, and/or getting a lot of power through an extension cord.

With everything above you may even start to doubt whether you actually need these 30 amp plugs on a generator.

Whether or not this is the case depends on what devices you want to power.

The 30 amp plug on a generator is for powering devices that need this many amps or less.

For example, RVs and devices like air conditioning systems tend to require 30 amps and often even more.

You should also often be able to power devices like coffee makers, a microwave, a refrigerator, a TV, etc. that actually require less power through the 30 amp plug on your generator.

## How many appliances can run on 30 amps?

How many appliances you can run on 30 amps depends on the number of watts and volts available.

As an example, a small microwave oven, a refrigerator, and a TV can typically run on a 30 amp generator.

Since the amounts of watts a power source offers does not only depend on amps, there is not a single answer to how many appliances can run on 30 amps.

That being said, let’s say your specific 30 amp outlet offers 3600 starting watts.

In that case, you would likely be able to run a light microwave oven, a refrigerator, a TV, and potentially more than these three appliances on 30 amps.

It is worth noting again that these are rough general statements.

How many appliances your inverter generator or other 30 amp power source will actually be able to run depends on other details too.

When in doubt, you want to do the specific calculations for your personal situation.

## Will a 30 amp generator run a house?

Yes, a 30 amp generator will often run a house with a small to medium number of devices if you set it up safely.

However, the watt capacity of the 30 amp generator and the devices inside the house will influence the details a lot.

In more concrete terms, 30 amp generators can often (but not always) power one or a few small to medium electric devices.

Connecting your generator to your house requires certain safety precautions like a transfer switch too.

Additionally, some devices like big AC systems can actually need more amps. A 30 amp generator is not strong enough for these. You would not be able to run a house that has one of these

### How many watts can a 30 amp breaker handle?

A 30 amp breaker can handle 7200 watts at most with 240 volts. With 120 volts, a 30 amp breaker would only be able to handle 3600 watts.

Breakers cut off the electrical circuit when there is an overcurrent.

To estimate how much a 30 amp breaker can successfully handle you can use the Watts = Amps x Volts formula.

For example, let’s say there is an electromotive force of 240 volts involved. In that case, a 30 amp breaker could be able to handle 7200 watts.

That being said, 30 amp breakers are as their name implies, made to flip at 30 amps. The number of watts is actually less relevant.

### What size generator do you need for 30 amp breaker?

You need a generator with 7200 watts of power or more to make full use of a 30 amp breaker with 240 volts.

On the other hand, with 120 volts, you would only need a generator size that offers 3600 watts to get the most out of the 30 amp breaker.

What size generator you need to make full use of a 30 amp breaker again depends on the volts involved.

### Is a 30 amp generator enough for a house?

No, a 30 amp generator is not always enough for a house. There are houses with big AC systems that need more amps than this.

Additionally, some 30 amp generators do not produce a lot of watts. This could limit the number of appliances you can run inside the house.

On the other hand, there are also 30 amp generators that are strong enough for a house.

### Can you run an RV air conditioner on 30 amp a generator?

Yes, you can typically run an RV air conditioner on a 30 amp generator.

That being said, it is likely worth double-checking the watts the generator offers and the air conditioner needs.

Especially if you also plan to power other electrical devices at the same time.
