What Size Breaker for a Dishwasher? Detailed Answer

Image by ecmag

You recently invested in a new dishwasher, and now you’re wondering whether or not the electrical system in your home can support its operation. You are probably thinking, at this point, what size breaker should be used for a dishwasher.

Utilize a circuit breaker rated at 15 amps for the dishwasher. Most modern dishwashers have amperage demands that are often lower than that level of electricity draw.

Depending on the particular configurations, it may also be possible to utilize different circuit breakers for dishwashers. However, to avoid accidents and other costly errors, it is crucial to double-check all of the necessary particulars, such as the power requirements for the dishwasher.

What Is the Appropriate Breaker Size for a Dishwasher?

You can use either a 15 or 20-amp circuit breaker for your dishwasher; however, the device you select must be single-pole. However, you should continue this decision carefully because of the potential consequences.

Should I Upgrade the Circuit Breaker Serving the Dishwasher from 15 Amps to 20 Amps?

The improper operation of the incorrect circuit breaker can have severe repercussions, including the start of house fires. This is since the wiring used for a standard 15-amp circuit breaker often has a safe power draw rating up to that amount.

Therefore, if you suddenly switch to a 20A breaker and the wiring gathers more current than it is capable of handling, the outcome can be a circuit that is overloaded.

Is It Possible to Connect a Dishwasher and Refrigerator to the Same Circuit?

‘Does a dishwasher need a dedicated circuit?’ is another subject that property owners frequently inquire about. The correct response is that most dishwashers should have their circuit breakers.

In light of this, you may also be curious about the circuit breaker size required for the dishwasher and the disposal. If you wish to connect garbage disposal and a dishwasher to the same electrical line, you must use a circuit breaker with a capacity of at least 20 amps rather than one with only 15 amps.

Additionally, you need to ensure that the amount of amperage drawn by the garbage disposal and the dishwasher does not exceed 80 percent of the maximum amperage rating for the circuit. It is expected that doing so will prevent issues such as overloads and short circuits.

Is It Possible to Plug a Dishwasher Into a Regular Outlet?

It is feasible to run a dishwasher off a standard outlet of 230 volts. Before moving on with this choice, however, you need to ensure that the dishwasher’s electrical requirements have been met. In addition, you need to make sure you use the appropriate circuit breaker type and size for the dishwasher.

Is It Better to Have a Dishwasher Hardwired Rather Than Plugged In?

In some circumstances, a dishwasher with a plug-in connection rather than one that requires hard wiring may be preferable. On the other hand, the contrary is a possibility in a few configurations. Keep reading this section to discover more about the potential benefits and drawbacks of each alternative

Hardwiring a Dishwasher

When you connect a dishwasher to a circuit breaker using hardwiring, you eliminate the requirement for an additional electrical outlet to power the device. The most significant drawback of this configuration is that the dishwasher cannot be removed quickly and efficiently.

On the other hand, the dishwasher should be connected to a more reliable power source rather than being plugged into an electrical outlet. In addition to that, this configuration typically calls for a GFCI dishwasher circuit breaker.

Plugging in a Dishwasher

Plugging this appliance into a wall socket or extension cord might not necessitate using a GFCI circuit breaker. This practice is also known as pig-tailing. However, the location of the wire could prove to be troublesome, mainly if the kitchen is an area with a lot of foot activity.

If you need to drill a cabinet hole to accommodate the plug, this concern may become more obvious.

Nevertheless, customers who desire a portable configuration for their dishwashers might find that employing this rather than hardwiring techniques would be excellent.

Frequently Asked Questions

Should the Circuit Breaker That Serves the Dishwasher Be a GFCI Breaker?

It is recommended that, if possible, a GFCI circuit breaker be utilized to forestall any mishaps that would otherwise be brought on by the high level of moisture in the surrounding environment. When it comes to preventing unwanted electrical problems with a dishwasher, a GFCI breaker is typically the best option to go with.

What is the maximum amp rating for a dishwasher?

The typical amount of amps required by domestic dishwashers is 10. For safety reasons, your circuit breaker should have a greater rating than the appliance now being used.

How Many Amps Does a Dishwasher Use?

Even when operating at full power, a standard dishwasher will not require more than 15 amps of current to function. The majority will work somewhere in the range of seven to ten amps. However, to correctly wire your kitchen, the dishwasher must be on a separate circuit from the rest of the appliances.

If your kitchen’s construction occurred before 2017, there is a reasonable probability that the dishwasher and the other appliances share the same electrical circuit. This is because the world of electrical rules and laws is constantly evolving to accommodate new standards and regulations. It’s possible that when it does, the necessities in your kitchen will shift without you even noticing it.

Would 14 gauge wires be appropriate for a dishwasher?

The circuit for the dishwasher must be set to 120/125 volts. This circuit with 15 amps has a 14/2 NM wire inserted into it. You can also connect the dishwasher to a circuit that has a capacity of 20 amps and uses a 12/2 NM wire.

Conclusion

You should now have a general concept of what size breaker to use for a dishwasher now that you have reached the end of this post.

Before moving on, it is strongly recommended that you either speak with a qualified electrician or review the electrical diagram for your home. This is of utmost significance if your dishwasher does not get along well with the breaker that is currently installed.
