Hey Francis, so it really depends on what the circuit will be used for. The standard recommendation for this circuit is 10 gauge wire like the # 10-1-1 (sold by foot) but if the circuit won't be drawing that much amperage there's no reason 12 gauge like part # 12-1-1 wouldn't work. It wouldn't overheat the wire unless it was getting overdrawn by something. Without a circuit attached drawing amperage the circuit would not just by itself get the wire warm.
That said, to charge a trailer battery decently 10 gauge is the way to go. 12 gauge won't get hot or anything but the charge would be so low it wouldn't be much worth it.
