I'm looking for experience regarding what wire gauge to use between a Power Converter and 12v Battery.
My run is about 6 feet and I have some 12 AWG wire but I am concerned that it might not be thick enough. The converter is a 45amp Power Wizard. I don't plan to draw a of of power (lights and a fan) but I'm wondering about the load during the charging cycle.
One thing you can do if you already have 12ga wire is to double it up, then connect it back together at the ends. 2, 12ga stranded wires are equal to 1, 8 ga single wire and usually alot cheaper too. A trick I learned in outdoor lighting where 8 ga is very expensive.
