I'm putting in a 100A subpanel in a damp area. I'm running 1 1/4" Sched40 PVC from the main panel (sized from NEC Table C.10). Planning on using 3 - #3 copper THHN (from table 310.16). Reading 250.122 (and 250.4(A)(5) and (B)(4)), it sounds like #8 bare copper stranded is fine for the ground, but I assume I'm better off going larger?

Also, anyone out there up to date on pool equipment grounding/bonding requirements?

I've done alot of home wiring, but am using this project as my first opportunity to interpret the NEC codebook. Let me know where I screw up!
