NEC Rules for Pools, Tubs, Fountains, and Spas ― Part 4

Sept. 3, 2019

More Article 680, Part IV requirements you need to know

Article 680, Part IV provides the requirements for electrical equipment associated with spas and hot tubs. This may seem redundant with Part III (storable pools, spas, and hot tubs), but it isn't.

Some highlights:

You must install a clearly marked, readily accessible emergency switch within 5 ft of the spa/tub and within sight of it [Sec. 680.41]. This isn't required for one-family dwellings but consider including it.
Indoor and outdoor installations must also comply with Parts I and II of Art. 680.
For outdoor installations, you can bond on a common metal base or frame [Sec. 680.42(B)].
For indoor installations, you must supply at least one 125V, 15A or 20A receptacle at 6 to 10 ft from the inside wall of the spa/tub [Sec. 680.43(A)].
Receptacles must be GFCI protected [Sec. 680.43(A)(2) and (3)].
Lights and fans installed over an indoor spa/tub must be mounted at a minimum of 12 ft if not GFCI-protected. If GFCI-protected, the height requirement is reduced to 7 ft, 6 in. [Sec. 680.43(B)(1)].
The height limit is waived if either condition in Sec. 680.43(B)(1)(c)(1) or (2) is met.
