Re: Gauge size between batteries and converter?
Do you mean a standard converter box which normally has no more larger wire size than the modern cars? If so, you do not need a wire larger than that, cause that is what they came with, and besides, the converter can only handle a small amount of amperage, if you read its specs. That size is what i use on mine.. However, the main 12v cable i have running under the bus from front to back is very large. The copper itself is 3/4 inch in diameter. That way, i have plenty of amps to start my generator which is where the front steps were. (and some line taps along the way)
Jesus Christ... Conversion in progress.
