What Appliances Should Be on a Dedicated Circuit?


Proper electrical function and access in a home is necessary to support normal daily activity. As you know, we need power for lights, cooking, security, entertainment, and more! Though many of these can be wired to operate on the same circuit, there are some that absolutely must be placed on a singular, dedicated circuit. In this article, we will explain why a dedicated circuit is a must for certain appliances, big and small.

What are Dedicated Circuits?

Dedicated circuits are circuits that are completely devoted to powering a single appliance or electrical application. They have a singular purpose, and their own place is in your breaker box where they are completely separate and do not interact with other circuits and outlets in your home.

Dedicated circuits should be used for any appliance that draws large amounts of power on a consistent basis (fridges, HVAC, etc.) or things that pull a sudden and heavy draw (hair dryers, microwaves, etc.).

Why Do I Need Dedicated Circuits?

It may seem a bit frustrating to go through all of the effort to get a dedicated circuit for each and every one of the items described above. But it’s very important! Ensuring the proper appliances are on a dedicated circuit prevents a lot of common home risks, helping keep you and your property safe. Doing so is also part of the standardized NEC safety codes.

By using dedicated circuits, you can avoid:

  • Flickering lights
  • Breaker trips
  • Potential home fires
  • Appliance damage
  • Risks of electrical shock

Appliances that Must be on a Dedicated Circuit

An easy rule of thumb to follow when it comes to dedicated circuits is that anything that is fixed (installed and not moved around) should be on a dedicated circuit. Such things would typically include:

  • Refrigerators and standing freezers
  • Heating and cooling systems
  • Ovens, stoves, and ranges
  • Hot water heaters
  • Sump pump systems
  • Microwaves
  • Certain televisions

There are also plenty of smaller and mobile items that should also be used on dedicated circuits, such as:

  • Portable space heaters
  • Window air conditioners
  • Hair dryers
  • Toasters
  • And more

Because of this need for dedicated outlets for smaller items, our experts frequently recommend that a “general use” dedicated circuit be installed in many rooms throughout the home. A general use outlet in a bathroom, for example, allows for the safe use of hair dryers when needed, while one in the living room allows for plugging in a space heater or Christmas tree in the winter season.
