Out of curiousity, you guys in PA....does your areas require any permits for your work?
Article 680 covers pools, and as Greg said 680.26 (2005) for bonding.
As to the receptacles:
AG pool filter, 120 volt, 20 amp twistlock, w/bubble cover no more than 3' from filter motor. (Filters have factory 3' cord w/twistlock cap) Circuit requires GFI protection; CB or deadfront device. You need a general purpose GFI no closer than 10' and no further than 20' from pool.
Bond is #8 solid (bare or green); all metal objects within 5' of pool edge, including heater, filter, frame, ladder, metalic deck/platform, fence, etc.
