A typical hot tub is "storable" and thus not subject to 680.23. Part III of Article 680 vs Part II of Article 680.

Cheers, Wayne

Not here. Out of hundreds of hot tubs I inspected i only ever saw 2 storable hot tubs.

Are you using "hot tub" as being distinct from "spa"? The typical "spa" I'm familiar with has "nonmetallic, molded polymeric walls" and thus meets the 2020 NEC Article 680 definition of being "storable".

The definition in the IRC for a hot tub or a spa is the same:

SPA OR HOT TUB. A hydromassage pool, or tub for recreational
or therapeutic use, not located in health care facilities,
designed for immersion of users, and usually having a filter,
heater, and motor-driven blower. They are installed indoors
or outdoors, on the ground or supporting structure, or in the
ground or supporting structure. Generally, a spa or hot tub is
not designed or intended to have its contents drained or discharged
after each use.

The definition in the IRC for a hot tub or a spa is the same:

OK, then 2020 NEC Article 680 also defines what it means for a spa or hot tub to be storable (emphasis mine):

"Storable Swimming, Wading, or Immersion Pools; or Storable/Portable Spas and Hot Tubs. Swimming, wading, or immersion pools that are intended to be stored when not in use, constructed on or above the ground and are capable of holding water to a maximum depth of 1.0 m (42 in.), or a pool, spa, or hot tub constructed on or above the ground, with nonmetallic, molded polymeric walls or inflatable fabric walls regardless of dimension."

Most of the spas I'm familiar with meet the bolded criterion.

Now, I was about to say "as such they are subject to Part III of Article 680 and not Parts II or IV." But I see that while Part III applies to "storable pools, storable
spas, or storable hot tubs," Part IV says it applies "spas and hot tubs".

So I guess post #22 is in error, as storable spas and hot tubs are subject to both Parts III and Part IV. And 680.42 (Part IV) says outdoor spas and hot tubs shall comply with Part II.

Does it have a luminaire? 680.23

Take II:

As this section applies to branch-circuit wiring (the title of 680.23(F)), if the disconnect in the OP contains OCPD, the supply to it is a feeder, not a branch circuit.
Thus the requirements of 680.23(F) do not apply to the supply side of that disconnect.

Looks like it depends on which code you are on or if it goes through a corrosive environment.
If it is 5' away, is it automatically not in a corrosive environment?

Or wet and outside and underground is a wet location

Correct....then we are back to whether or not the disco and therefore the feeders are in the corrosive environment or in the case of 2023, a wet location which would likely only get a pass if the disco was mounted on the exterior wall of the dwelling, but some people will argue that as well...
