I haven't read through this whole thread, so this may have been covered.
Get the nameplate information off each piece of equipment, pumps, heater, lights, etc. and I'll run a load and VD calculation for you when I get to work.
I agree with everyone else, don't use aluminum. Aluminum wires have burned down more houses than anybody will admit to. We don't even spec aluminum at work. If the owner wants to VE to aluminum, that's 100% on them.
Thank you. I don’t have access to the name plates of the equipment because the pool isn’t being installed until next June. The best I can do is pull the specs from the manufacturer. Which is Hayward for the heat pump and water pump. The salt system and LED pool light I’ll have to call the pool company about. I’ll try and track that down.
