![]() Self-contained (portable), circuit breaker, or receptacle type GFCI are acceptableĭo Inflatable or Portable Hot Tubs Need GFCI?.Indoor hot tubs require the following type of GFCI: All receptacles on a 125V circuit 30 amps or less require GFCI protection if located within 10 ft (3 m) of the hot tub.At least one general-purpose receptacle is to be installed between 6 ft (1.83 m) and 10 ft (3 m) from the hot tub.The NEC asks for the following requirements for indoor hot tubs: Receptacles (Outlets) for Indoor Hot Tubs This applies to inflatable, portable, and permanently installed hot tubs. Outlets need to have a waterproof coveringĪll indoor hot tubs swim spas and the like require GFCI protection.Receptacles should be installed no higher than 6 ft 6 inches (1.83 m) above the surface of the water.You must have a minimum of one outlet located between 6 and 10 feet from the hot tub.Receptacles must be a minimum distance of 6 ft (1.83 m) from the inside walls of the hot tub or spa.Are located less than 20 ft (6 m) from the inside walls of the hot tub.Must be a Class A type (trips at between 4 and 6 mA).GFCI protection is required for receptacles and convenience receptacles (outlets) as follows: Outlets and receptacles for hot tubs located outside need GFCI protection.

All of this information has been pulled from The National Electrical Code (NEC) or NFPA 70. We have summarized the GFCI requirements for hot tubs in this article. Electrical Codes & Regulations for Hot Tubs A GFCI in a hot tub will switch the power off when the current is between 4 and 6 mA to prevent serious injury or death. ![]() A current of 30 mA is enough to cause heart fibrillation, which can lead to cardiac arrest. Situations such as water splashing on an electrical component, a fault with a motor, and a person touching a live line can all cause a GFCI to trip.Įssentially, the GFCI is designed to turn off the power very quickly to prevent fatal electrocution. The GFCI monitors the amount of current (electrical flow) going to the ground and if it detects a current imbalance (usually 4-6 milliamps or greater) it will cut off the power. Exceptions to Hot Tub GFCI RequirementsĪ GFCI circuit breaker or ground-fault circuit interrupter is an electrical protection device that turns off the power should a fault in the electrical circuit occur.How Far Should a GFCI be From a Hot Tub?.How Much Does it Cost to Install a GFCI?. ![]() Do Inflatable or Portable Hot Tubs Need GFCI?.Electrical Codes & Regulations for Hot Tubs. ![]()
