Sparky,
Yes I can see the point you are getting at, if we follow word for word in the book it states receptacles, no mention of hardwire, this is strictly regarding Permanently Installed Pools(680.22(A)(5).
Then in 680.21(A)(3), if liquidtight is used then there is no longer a receptacle being used, so no need for GFCI?
I have not come across a pool pump as your standard aboveground setup that is 240v yet, typical is 120v 15/20A. And just last year saw my first twistlock factory installed cord-and-plug configuration. Now they ought to supply the receptacle with it.
If there is a pool utilizing single phase 240v over 20A, I would assume that it would be housed in a pool/pump house that typically the average homeowner doesn't go trying to play electrician with the connections, and by the NEC would mean no GFI protection because an electrician should know how to be safe?
As far as the 240v 50A disconnect, moving into Spas and Hot Tubs, it does require GFI protection, excluding the exceptions as listed.
SBSG model LC220-D, 240v 50A GFCI and Disconnect.

They also make a 240v 60A model.
The Milbank shot was a guess, they are commonly linked because they both have letters in the alphabet.M N O P Q R S, well kind of distant cousins at best.
