Does a Hot Tub Need a GFCI Breaker?

If you are preparing to install your newly bought hot tub you may be wondering, does a hot tub need a GFCI breaker? According to the National Electrical Code, any outlet that supplies a hot tub or spa must be GFCI protected. There are also some other considerations which must be followed depending on if you will be installing your hot tub indoors or outdoors.

To find out more about what you need to know about hot tub GFCI requirements as well as other important installation safety factors, keep reading below.

GFCI for Indoor Hot Tubs

The ground-fault circuit interrupter (GFCI) requirements for indoor hot tubs are as follows:

• There must be at least one convenience receptacle located between 6 to 10 feet from the inside wall of the hot tub.
• The receptacle must be GFCI protected.

GFCI for Outdoor Hot Tubs

The ground-fault circuit interrupter (GFCI) requirements for outdoor hot tubs are as follows:

• There must be at least one convenience receptacle located between 6 to 10 feet from the inside wall of the hot tub.
• The receptacle must be GFCI protected.
• Nonmetallic conduit or liquid-tight flexible metal is permitted if the receptacle is less than 6 feet away.
• An outdoor hot tub can be cord and plug connected provided that the receptacle is GFCI protected and does not exceed 15 feet in length.
• Outdoor receptacles need to have a weatherproof cover where exposed to the elements.

As requirements can vary and change from time to time if you have any questions you should always reach out to your local electrical inspection agency.

Hiring an Electrician

Wiring your hot tub should not ever be a DIY project. Electricity and water do not mix, so it is important that you hire a professional electrician to safely hook up your hot tub. An electrician will be familiar with the National Electric Code and will know exactly what type of wiring to use, the right size breakers to use as well as what proper conduits and disconnects are needed to ensure safety.

An electrician can have your hot tub wired and working quite quickly, meaning you can take your first soak, safely, in your new hot tub shortly after it arrives.

If you are looking for recommendations on local electricians, speak to your hot tub dealer. They will be able to connect you with professionals in your area that have worked on a number of hot tub installations.
