If you’re in the process of installing a dishwasher in your home, one of the most important considerations is the type and size of electrical circuit breaker you’ll need to accommodate the electrical current required by the dishwasher. While most dishwashers require a standard 120-volt, 15-amp circuit breaker, some models require a 20-amp circuit.

In order to determine what size breaker you need for your dishwasher, it’s important to consult the owner’s manual or other documentation that came with the appliance. If you no longer have this documentation, you should be able to find the information online by searching for the make and model of your dishwasher. Once you know what size breaker is required, you can purchase one from a hardware store or home improvement center.

What Size Breaker Do You Need for a Dishwasher?

Most dishwashers require a 15-amp circuit breaker. If your dishwasher is on its own circuit, it is best to use a 20-amp breaker. If you are unsure of what size breaker you need, you can consult your dishwasher’s manual or a professional electrician.

What is the wattage of your dishwasher?

The wattage of your dishwasher will be printed on a label affixed to the back of the machine. If you can’t find it there, consult your owner’s manual. You’ll need to know the wattage in order to determine the proper size breaker for your dishwasher. Most dishwashers use between 1,000 and 2,000 watts, but some higher-end models may use more.

What is the amperage of your dishwasher?

The amperage of your dishwasher is the number of amps that the appliance uses. Dishwashers typically use between 10 and 15 amps. If your dishwasher is using more than 15 amps, you may need a bigger breaker.

What is the voltage of your dishwasher?

When attempting to determine what size breaker you need for a dishwasher, the first thing you need to do is identify the voltage of your dishwasher. The voltage of a dishwasher can range from 110 volts all the way up to 240 volts. Once you have identified the voltage of your dishwasher, you can consult a breaker size chart to determine the appropriate size breaker for your home.


As you can see, there is a lot to consider when it comes to finding the right size breaker for your dishwasher. If you have any doubts, it is always best to consult with a professional.
