Calculating wire size and voltage drop
I'm in the process of adding a second battery bank. The bank is two 6v GC2 @220 AH. I've finally nailed down some exacting measurements and have totalled the two runs from the bank to the distribution...

Verify the gauge by getting the circular mil spec for that gauge. Too many errors re: SAE versus AWG. Someone claims they are selling "2 gauge wire" ask for the circular mil area of the conductor. If they refuse, drop the phone receiver back on the hook. AWG is about 4% larger, and is GUARANTEED to be a certain circular mil value. SAE is made in "Xhualung Province" and is guaranteed to have at least some copper and plastic in the product.
