I will soon be installing a new "house battery" in my camper van and wanted to make sure I use the correct gauge wire.
There is currently a 4 AWG wire tapped into the middle of the positive cable from the battery to the starter which is tied to the current house battery with a manually switched solenoid.
I want to move the batteries to a location under the van (I will have a remote temp sensor set up for the battery/charge controller) and wantt o make sure I use large enough wire, the run, one way from the current tie in to the positive cable, will be 10', I have a 150 amp alternator, according to this chart, http://www.offroaders.com/tech/12-vo...gauge-amps.htm I will only need 8 AWG wire which seems quite small, I do have enough 4 AWG around which I think should be enough but just wanted to make sure before I plan on using it. I will be able to ground the battery to the chassis right next to the battery.
Will the 4 AWG be fine for my application?
