Hi guys, I want to add one of those Perko battery switches on my two batteries in my boat. I am ordering the parts on line, and I do not know what sized cable to purchase to install from the batteries to the switch? I am thinking a 4 Ga. wire, but something is telling me to get the 2 Ga. wire. I have no heavy electronics on my boat. It is a 16.5 ft aluminum boat with a bilge pump, a live well pump, navigation lights, a fish finder and an am/fm radio and a horn. Electric start 70 h.p motor. The wires going to the battery from the starter and ground right now do not have a sized label on them, so I do not know what size they are. Is there a standard size on these wires? Thanks.
edit: I should also mention that the distance (run) of the wires that I will be installing is only about 15 inches, from the batteries to the switch.
