The project is to wire a sub-panel and three pool circuits. My 400A main panels (2) are about 35' away, and I don't have room inside the basement to mount the sub panel inside. I plan to use an Intermatic PE20000 60A outdoor load center (or a fancier PE25065RC that includes remote controls), and I will mount this on the outside of the house about 40' from the main panels. The load center will have three circuits to feed a 1.65HP 230V variable speed pump and two (2) 15A receptacle circuits (lighting & convenience).
- Location is Virginia
- 14'x33' fiberglass in-ground pool located ~40' from house and sub-panel
- Hayward SP2303VSP pump (230v variable speed)
- No heater or other powered equipment
- Lighting circuit will supply (2) 12v transformers for (2) LED pool lights
- Convenience receptacle is required within 20' of the pool edge
I would appreciate any guidance on the following:
- 30A 2-pole GFCI
Sub panel (Intermatic PE20000):
- 15A 2-pole breaker (non GFCI) (pump)
- 15A 1-pole (non GFCI) (lighting recept)
- 15A 1-pole (non GFCI) (convenience recept)
- Non-bonded neutral and ground
- No additional ground rod
Wire from main to sub:
- (4) #10 THWN-2 copper stranded (~40' runs)
Wire from sub to circuits:
- (3) 12' #10 THWN-2 copper stranded from sub panel to 230v pump (L1, L2, ground) in watertight conduit (#10 to future proof the wire)
- (3) 60' #14 THWN-2 copper stranded from sub panel to 120v lighting receptacle (L, N, ground) via 3/4 schedule 80 PVC
- (3) 100' #14 THWN-2 copper stranded from sub panel to 120v convenience receptacle (L, N, ground) via 3/4 schedule 80 PVC
- All 3/4" schedule 80 conduit buried at 18"
Equipotential bonding: ~300' of #8 THWN-2 copper solid (bare) with equipotential connections to:
- 3' horizontal under pool coping/pavers around pool perimeter
- deep end stainless steel ladder anchor plate
- 230v pump ground (it's not double-insulated)
- bonding electrode within PVC at pool filter
- not bonded back to the sub panel
Is the #14 THWN-2 feed from sub panel to 230v pump sufficient (10FLA)? Consensus is yes per the pump manual
Are the #14 THWN-2 20A circuit feeds sufficient for those lengths (90 deg THWN-2 #14 copper should be 25A)? Consensus is yes
Does my #8 solid equipotential ground need to connect back to the sub-panel, or is the connection at the pump sufficient to tie back to the main ground? Not back to the subpanel - just to the pump.
Any recommendations for making things cleaner?
