Wiring an Outside Hot Tub (NEC 2002)

Wiring a hot tub is not as easy as it looks. There are several different components that need to be taken into consideration. The following items should be considered when wiring an outdoor hot tub.

• All non-current carrying metal parts within 5’ of the hot tub must be bonded by a #8 copper wire (680-41-D)
• No receptacles are allowed within 10’ and no switches are allowed within 6’ of the hot tub.
• Branch circuit conductors that serve motors must be in a conduit (680-25-C and 680-40)
• If the outside hot tub is a self contained unit with built-in CFCI protection, no further CFCI protection is required (680-42)

• Use a flexible conduit or cord no longer than 15’ if you are using CFCI protected conductors (680-40-A)
