How many amps a 6000 watt generator is influences what you can run and what breakers you need.

Many people will head straight to the Watts = Amps x Volts formula to answer this question.

The result of this would be that a 6000 watt generator offers 50 amps at 120 volts and 25 amps at 240 volts.

However, in the case of 6000 watt generators, the built-in outlets typically limit the number of amps you can get out of your machine to 30 amps at 120 volts.

When running 240 volt devices, you could get a 25 amp breaker to make sure your 6000 watt generator keeps functioning as desired.

How many amps can a 6000 watt generator theoretically produce?

Your first reaction when figuring out how many amps a 6000 watt generator should produce may be to turn to the Watts = Amps x Volts formula.

With this formula, you would estimate that a 6000 watt generator offers 50 amps at 120 volts.

Similarly, this formula would imply that a 6000 watt generator offers 25 amps when producing 240 volts.

That being said, you need to know that the formula above is not the complete story when working with portable generators.

How many amps can you actually get out of a 6000 watt generator?

The number of watts is actually not the only detail that influences how many amps a generator can offer you.

How strong the outlets are play an important role too.

6000 watt generators tend to come with outlets that can “only” handle 30 amps.

In turn, you can only get 30 amps out of your 6000 watt generator at 120 volts (and still 25 amps at 240 volts unless you parallel two models).

It might even be possible that there are 6000 watt generators with only 20 amp outlets although I have not seen these yet.

What size breaker do you need for a 6000 watt generator?

You can describe circuit breakers as devices that interrupt your electrical circuit when too much power goes through.

This can help you protect your electrical circuit which can only handle so much power.

Additionally, in the case of portable generators, circuit breakers can help you avoid overloading your machine.

What size breaker you need for a 6000 watt generator depends on what things you want to protect and what you want to run.

For example, to make sure your 6000 watt generator functions as desired when running 240 volt devices, you would get a 25 amp breaker.

However, if your electrical circuit can only handle 20 amps, this should be the size of your breaker.
