Yup, more old pool rehab questions. The old wiring is pretty sketchy and corroded, not to mention definitely not up to current code. So here's my plan.
Secure pressure treated 4x4 post in ground and mount Intermatic T21004R pool time/panel at the equipment pad. (about 15ft from pool)
Bury 1" PVC conduit 18" deep from house to the equipment pad. (about 80ft)
Feed sub-panel with 50 amp 2P breaker in main panel. 6-3 w/ground Romex inside and 4 legs of #6 THHN outside. (2 hot, 1 neutral, 1 ground.) Ground and neutral not bonded at sub-panel. No ground rod needed.
Run flexible liquid-tite conduit with #12 THHN inside to feed the pump from the sub panel with a 20 amp 240V breaker.
Install GFCI convenience outlet in box (Intermatic gives a spot for one) and feed with a 15 amp breaker.
Is a GFCI breaker required for the Pump feed, or should I protect the entire sub-panel with a GFCI breaker in the main box and regular outlets and breakers in the sub-panel to handle the pump and outlet protection requirements?
