Why A Dehumidifier Needs A Dedicated Circuit

KB Electric LLC gets calls every week for dedicated line, circuit, and outlet installations needed for big appliances (washer and dryers, refrigerators, ovens, window A/C units, microwaves, etc.), EV chargers, and special equipment hookups. Dedicated circuits are very important for these items because of the amount of amperage they draw. Something that a homeowner may overlook is plugging their dehumidifier unit into an extension cord on a non-dedicated circuit, or an outlet on a non-dedicated circuit. Let’s take a closer look into why a dehumidifier needs a dedicated circuit and who to call for a dedicated circuit, line, and outlet installation.


What Is A Dehumidifier?

A dehumidifier is a household appliance that removes moisture from the air in a room/living space. Common areas in a household with dehumidifiers are basements, crawl spaces, bathrooms, and kitchens. The room in which you place your dehumidifier might vary from house to house based on which room/area in a home is really humid.


Benefits of A Dehumidifier

As mentioned, a dehumidifier pulls moisture out of the air of the room. This provides many benefits:

  • Prevents mold and mildew growth.
  • Reduces allergens that contribute to dust, mold, and mildew.
  • Reduces insect/pest issues.
  • Protects household items and clothing that are prone to damage due to mold and mildew growth.
  • Helps breathing issues.
  • Provides more comfort in a room. 


What is A Dedicated Circuit?

A dedicated circuit is a circuit/breaker in your main electrical panel that is only hooked up to one specific household appliance in conjunction with a dedicated line and outlet. The circuit will be rated for that specific appliance/device’s amperage so that it can run without causing a tripped breaker, overheating of wires, and for the prevention of damage to the household appliance/device/unit.

Why A Dehumidifier Needs A Dedicated Circuit

If you are ready to own one, a dehumidifier needs a dedicated circuit installed with a dedicated line/wire ran to a dedicated wall outlet/receptacle. A dehumidifier needs this dedicated line and outlet to operate because dehumidifiers can utilize anywhere from 2 to over 7 amps, depending on the size of the unit. That may not seem like a lot of juice, but in addition to other devices and appliances together, it can add up. This is why it is not recommended to use a dehumidifier on the same circuit with other large appliances and devices, and especially not with an extension cord if your wall outlets are maxed out.

It’s best to put your dehumidifier on its own dedicated circuit because of the following:

  • Prevents tripping breakers.

  • Prevents blown fuses.

  • Prevents overheating of wire insulation.

  • Prevents electrical fires.

  • Prevents damage of the dehumidifier.
