All appliances in your Central Texas home require electricity, some more than others. In fact, certain appliances require so much power that they need their own circuit. Failing to secure a dedicated circuit can result in an electrical overload, which can trip your circuit breaker and can possibly damage your electrical system. To maintain electrical safety for your home, you’ll need to know which appliances require a dedicated circuit.

The experts at Salt Light & Electric have detailed 5 appliances that require their own circuit!


A washer and dryer are an unbreakable duo, even when it comes to the circuit. Although they are usually plugged into different receptacles, both major appliances run on the same dedicated circuit.

The voltage requirement of a washer and dryer can range from 120-240V. The dryer uses considerably more energy than the washer, due to heating. But the washer evens this out with its water usage. Thus, both of their energy consumption is proficient and is the reason they require their own circuit.


Refrigerators work 24/7 to preserve perishable food. To maintain its contents, a dedicated circuit is needed to provide this constant power.

Most refrigerators require a voltage of about 120V. A 15A or 20A receptacle will usually perform this job. 15A and 20A outlets are the most common type in your home, and often the outlets you use the most. A refrigerator’s outlet however, should only be used for the refrigerator!


Microwaves come in many different sizes and varieties. But one thing that remains common is their requirement of a dedicated circuit.

Microwaves should be plugged in to a dedicated 20A receptacle with a voltage of about 120V. Microwaves may not seem like they require a dedicated circuit at first. You may have even seen them plugged into standard outlets. However, this can lead to an overload. Microwaves use anywhere from 500-1800 watts of energy, which can overload a 15A circuit that has other appliances plugged in.

Electrical Oven

Electrical ovens are a voltage powerhouse. They require a dedicated circuit with a voltage of 240V. Additionally, they require a unique 50A receptacle.

Gas ovens also require their own dedicated circuit, but their voltage is a bit lower. More info about gas ovens and other kitchen appliances can be found here.

HVAC System

Since your HVAC system accounts for almost half of your home’s energy consumption, it’s no wonder a dedicated circuit is required. In fact, your heating and cooling may require separate dedicated circuits, but this varies on each home.

A furnace can require as much as 15,000 watts to properly run. This is more than 8 times as many watts a 15A receptacle can handle, which is 1800. A central air conditioner tends to use approximately 3500 watts, which can require another dedicated circuit.

By knowing the appliances that require a dedicated circuit, you’ll be able to help maintain electrical safety in your home. However, you’ll still need to know which circuits are dedicated, along with the condition of your electrical system. Contact Salt Light & Electric for affordable electrical inspection services.
