This question is how 680.42 pertains to a traditional portable spa or hot tub. Generally, as defined by part 1 of 680, these units meet the defenition of the following: stationary equipment, pool, self-contained spa or hot tub, self-contained theraputic tub or hydrotheraputic tank, spa or hot tub.
These packaged units generally DO NOT meet the defenition of permanently installed swimming, wading, immersion, and theraputic pools.
So, one would think that part 2 (permanently installed pools) of article 680 does not apply to your every day portable, self contained spa. Specifically, this means equipment grounding conductor can be bare as well as no required general duty GFCI outlet between 10 to 20 feet.
Now if this is the intent of the code why does 680.42 (C) exist?
I think 680.42 needs to be changed to say "...that would otherwise apply to permanently installed pools installed outdoors."
