SanDiegoChip is on a distinguished road
I got a call back into Josh at Lewmar for clarification on the 2 AWG or 2/0 AWG. I did use the calculators for loss. He must have meant 2/0 wire or I heard wrong. I have spent a bundle of cash and time and my wife and I are bruised and cut from the bow roller and bow pulpit re-install. We do not want to cheap out on this final part of the project and ruin all the fine work we have done. No matter what he says 4/0 is the way we will go. In this case bigger is better and I had been planning on 4/0 anyway. Just was not sure. Before I spent the $$ I wanted to be sure I was not just wasting money. Even though I have been checking the calculator for wire size I just do not seem to get it. I understand the loss, voltage drop some. Any way it makes sense what you say. I can understand that.
It is 25' one way or 50' round trip.

I get:
2 AWG

Voltage drop = 0.683
Voltage at load end of circuit = 11.317
Per Cent voltage drop = 5.69

2/0 AWG
Voltage drop = 0.34
Voltage at load end of circuit = 1.66
Per Cent voltage drop = 2.83

There is a big difference.
We will go with 4/0 (0000) wire.
Anything else I should watch for?
Like end fittings etc?
Thanks,
Chip
