Yes that more than throws a cat amongst the pigeons.
If the info you have posted is copied word for word out of the KK manual, then they should not be making letter boxes let alone caravans.
4.58mm2 cable is also called 6mm auto cable and the amp rating they have quoted is the maximum current the cable can handle before the cable’s plastic insulation starts to melt and has absolutely nothing to do with the work current of the cable.
4.58mm2 cable would be good when two standard sized batteries were side by side and then the voltage drop would be small.
8mm2 cable would be good when two standard sized batteries were both in the engine bay and again the voltage drop would be small and this cable can handle about 120 amps maximum current before the cable’s plastic insulation starts to melt.
No way on earth would anybody in their right mind try to put 210 amps down this size cable.
For KK to suggest that even the 8mm2, which would be 8B&S, would charge the batteries is totally ludicrous and shows how very little KK knows about 12 volt systems.
Using either of these cable sizes means you will never charge your caravan batteries, even if you drove for 24 hours straight, day after day.
The voltage drop would be so great that the voltage at the caravan batteries would never be high enough to even start to charge the batteries.
Garth and
John, don’t take my word just go and get some professional advice.
