What guage wire for 120 foot 110V ext cord to 45 amp Iota battery charger?
After great input on this site, I have bought a new Iota 45a charger for my house bank (2 new group 27 wet cells). As I am about 120 ft from the AC, at my marina, I would like to know what guage of wire I would need, to not overheat, during maximum charging.
I tried a voltage calculator, but would like someone with more electrical knowledge to advise me as well.
I will either buy a premade "high end" extension cord, or make my own, by buying the bulk wire and ends. I have a short, approx 20' heavy duty shore power cord, and require a 100' extension cord - total run = 120'
Thanks in advance!!
