Does a Hot Tub Need a GFCI Breaker?

If you are getting ready finalizing the installation plans for your hot tub, you may be wondering if your hot tub will need a GFCI breaker. Based on the National Electric Code, any outlet that is supplying power to a hot tub or spa needs to be GFCI protected. In addition, there are some other factors that need to be followed depending if your hot tub will be outside or inside.

Keep reading below to learn more about what you need to know regarding hot tub GFCI requirements as well as other important installation factors.

GFCI Requirements for Indoor Hot Tubs

The GFCI requirements for indoor hot tubs state that:

  • The receptacle serving your hot tub must be GFCI protected.
  • There must be at a minimum one convenience receptacle that is located between six to ten feet from the inside wall of your spa. 

GFCI Requirements for Outdoor Hot Tubs

The GFCI requirements for outdoor hot tubs state that:

  • The receptacle serving your hot tub must be GFCI protected.
  • At a minimum, there must be one convenience receptacle situated between six to ten feet from the inside wall of the spa.
  • If the receptacle is less than 6 feet away, non-metallic or liquid-tight flexible metal is permitted.
  • The hot tub can be cord and plug connected provided that the receiver is GFCI protected and less than fifteen feet in length.
  • Receptacles outside must have a weatherproof cover if they are exposed to the elements.

As requirements can vary and change from time to time, it is recommended that you or your electrician consult with your local electrical inspection agency to ensure that everything is up to code.

The Importance of Using an Electrician

Electricity and water do not mix, so installing your hot tub shouldn’t be a DIY project. It is essential that a professional electrician perform the work to ensure that your hot tub is hooked up safely. Electricians are well-versed in the National Electric Code and will know exactly what needs to be done along with what type of wiring to use, what size breakers to use as well as how many conduits and disconnects are required.

If you are unsure what electrician to use, speak to your local hot tub dealer. They will be able to provide plenty of recommendations for electricians that have installed many hot tubs in your area.

Once your electrician is at your home, it won’t be long until your hot tub is connected and running, meaning that you can jump in and take your first soak!
