Depending on the product and manufacturer’s guidelines, it may be possible to use an extension cord for a dehumidifier as a temporary solution.

Can You Use a Heavy-Duty Extension Cord With a Dehumidifier?

Every year, millions of dehumidifiers are sold across the United States. Dehumidifiers are one of the most popular additions to homes because of their ability to help make your home a more comfortable environment. Depending on the size of your humidifier and the number of electrical outlets your home may have, it can be tempting to use an extension cord to power your dehumidifier.

You can use a heavy-duty extension cord with a dehumidifier. They pull a lot of energy that a standard extension cord may not be able to support, but if the manufacturer of your particular model allows, it most likely would be okay to use a heavy-duty extension cord. 

Still, it should only plan to use it as a temporary solution.

When looking for a heavy-duty cord, you’ll need to understand the types of cord and their specific purpose. While it’s tempting to find the first cord you see that’s most cost-effective, it’s essential to find a heavy-duty cord suited for your dehumidifier.

Cords are rated and labeled with the following common letters:

  • S: S-rated cords are one of the most generic cords you’ll find in stores and are perfect for general functions within your home versus outdoor usage, but not for your dehumidifier.
  • W: W-rated cords are a slightly higher tier than S-rated and are safe to use outdoors as they have a waterproof layer to protect them from the outdoor elements, but not for your dehumidifier.
  • J: J-rated cords are higher insulated cords used for heavy-duty devices. However, J-cords will probably not have enough power for a dehumidifier.
  • P: P-rated cords are also heavy-duty cords that should be a temporary use for your dehumidifier, but you should check with your product manufacturer to confirm for any usage.

What Kind of Extension Cord Can I Use With a Dehumidifier?

Many manufacturers recommend not using extension cords for dehumidifiers in the owner’s manuals. As mentioned prior, dehumidifiers pull a lot of energy that an extension cord may not be able to handle. Additionally, a dehumidifier changes moisture to liquid which may be a safety precaution if it ever leaks.

While a heavy-duty extension cord may be a temporary solution, you’ll need to attach your dehumidifier to a power source such as a three-prong outlet that’s safe and reliable. Remember not to use an extension cord if the manufacturer recommends against it.


Can a Dehumidifier Be Plugged Into a Surge Protector?

Generally, dehumidifiers should only be plugged into the power source advised in the product manual. Most commonly, it’ll be a three-prong outlet. Now that we know that extension cords are to be avoided for dehumidifier usage, some folks may also wonder if a surge protector can be a three-prong outlet substitute?

Surge protectors should never be the source of power for a dehumidifier. Dehumidifiers contain a tank that gradually fills up with water. Any cords that can be found ground level can end up being a safety hazard if the dehumidifier was to ever leak to the ground. 

For this reason, it’s imperative to not only not place a dehumidifier near surge protectors or extension cords, but anything that can be an electrical or fire hazard if it were to get wet.


Why Do Some Appliances Say Not To Use an Extension Cord?

When you look at most appliances that require a power source, you’ll notice they advise not to utilize extension cords or use it as a temporary power source. Extension cords are a convenient way to bring power to a majority of your household devices and appliances.

Some appliances may say not to use an extension cord due to:

  • Your appliance may need a permanent power source to run efficiently. 
  • The appliance may draw higher voltage than an extension cord can provide, making the cord a fire risk.
  • Extension cords can be a hazard for heating and cooling operations.

When used without proper caution for their intended purposes, they can become fire hazards and pose significant injury or safety risks. It’s imperative always to read your appliance to ensure an extension cord is an allowed source of power for your product.

Another reason you may not want to use an extension cord with a dehumidifier is that, if it is out in the open, someone might trip over the cord.


Conclusion:

Overall, connecting a dehumidifier to a power source in your home isn’t a difficult thing to do. It’s imperative to use a three-prong outlet to connect and operate your dehumidifier.

Using a three-prong outlet ensures your dehumidifier is grounded.

An extension cord or surge protector can be a considerable safety precaution for your household due to the amount of electricity pulled into the cord and excessive heat. Remember to always consult your installation instructions for the electrical requirements for the model of your dehumidifier.
