Harold:

We're talking AG pools right??

Twistlock; GFI, etc, etc??

OK, math time; step by step...

Continuous load..80%...20 amps....16 amp max.
50% = 8 amps or 960 watts; 1 HP = 746 watts, 1-1/4 HP MAX.

OK? take a 1-HP filter, using the math, NOT the nameplate.....

Resi panel, 3/4" PVC, #12 THHN/THWN; run to a GP GFI 10-20' from pool;continue to twistlock at pool filter, 5' from pool, w/bubble cover; 3' cord on filter; math acceptable!

I read 680 (2005) and don't see any prohibition for the above.

Give me a call, or an e-mail if you want; I'm curious??? I'll be at te PGA 'till 8/14, but the cell is on.
