My pump will be 750' from the control box and generator. I planned to use #8 copper for a 1hp motor, which by the charts is good up to 950' for 1hp.
But I can get #6 aluminum a lot cheaper than #8 copper. #6 aluminum has the same ampacity as #8 copper.
Is there a consensus about using aluminum wire down the well, into the water? Advantages/disadvantages?
I thought about using #8 copper USE down the well (400'), then connecting at the well head to #6 aluminum XHHW from the well head to the control box (350'). Need special connectors to splice copper onto aluminum, but that's no big deal.
Anyone seen aluminum wire in a pump circuit after 30 years of service?
