What Size Breaker Do I Need for a Dryer

Dryers are one of the most common appliances in homes and businesses. They come in many different sizes and shapes, but they all have one thing in common: they need a breaker to function properly. But what size breaker do you need for a dryer?

The answer depends on the type of dryer you have and the voltage it uses.

If you’re unsure what size breaker you need for your dryer, there are a few things you can do to find out. First, check the owner’s manual for your dryer. The manual should have information on the required circuit breaker size.

If you don’t have the manual, you can look up the make and model of your dryer online to find this information. Once you know the required circuit breaker size, be sure to check your home’s electrical panel to see if there is already a breaker in that spot. If there is, make sure it is rated for the correct amperage.

If not, you’ll need to replace it with a new one. Finally, keep in mind that most dryers require a dedicated circuit all to themselves. This means that if there are other appliances or devices plugged into the same circuit as your dryer, they may cause it to trip the breaker or blow a fuse.

So if possible, try to plug your dryer into its own circuit before using it.

Can I Use a 40 Amp Breaker for a Dryer?

If you’re wondering whether you can use a 40 amp breaker for your dryer, the answer is maybe. It depends on the specific model of dryer and the voltage it requires. Most standard residential dryers operate on 240 volts and require a 30 amp circuit breaker.

However, there are some models that operate on 208 volts and only require a 20 or 25 amp circuit breaker. So, if you have a 208 volt dryer, you could theoretically use a 40 amp breaker, but it’s not recommended. If you have any doubts about what size circuit breaker your dryer needs, consult the owner’s manual or contact the manufacturer.

What Size Breaker Does a 220 Dryer Need?

A 220 dryer needs a breaker that is double the size of the dryer’s circuit. The dryer’s circuit is usually 20 amps, so the breaker would be 40 amps.

Can I Run a 30 Amp Dryer on a 20 Amp Breaker?

If you have a 20-amp circuit and wish to install a 30-amp dryer, you must first determine if the circuit can handle the increased amperage. The National Electrical Code requires that all 120/240-volt, single-phase branch circuits for 15 and 20 amps be protected by a 20-amp circuit breaker. You cannot replace the existing 20-amp breaker with a 30-amp breaker because this would violate code.

You must instead install a new 20-amp circuit breaker for the dryer on an unused portion of the panel.

What Size Breaker for 220V Dryer

If you’re wondering what size breaker you need for your 220V dryer, the answer is simple: a 30-amp breaker. This is the standard size breaker for dryers, and it’s what you’ll find in most homes. However, if your home has an older electrical system, you may have a 40-amp breaker for your dryer.

In this case, you can still use a 30-amp breaker, but it’s best to upgrade to a 40-amp breaker if possible.


While the average dryer draws around 1,500 watts, some models may use as much as 5,000 watts. This means that you’ll need a breaker that can handle at least 5,000 watts.
