Power from White Plug to Anderson Plug

The plug looks a bit of a mess but it's made up using three red and three black 8B&S ( 7.9mm2 ) cables wired in a triangle setup.

The Anderson 6 Gauge terminals will just accept two 8B&S cables.

This means the Anderson terminals can be used as the junction for each joint and while the cabling is 8B&S, the triangle configuration means you effectively have 15.8mm2 for each circuit.

This gives you the similar current carrying capacity as 6B&S cable and that means very little voltage drop across the plugs.

Yes the S12 was forgotten long ago, thanks for the circuit breaker suggestion. Good idea on the piggy back Anderson plug, amasing how obvious things are when someone has suggested a better way, I can do this on the van end (when I get it), it will be a bit neater I hope the wiring is up to the task. Not quite sure why the van manufacturer would provide a wiring diagram to wire the 12 pin plug to charge the batteries when it does not have the current handling capabilities. I guess I have a bit of rewiring to do at both ends.

You'd be supprised how much they do work on rainy/cloudy days, they still add charge, not as much as a clear day of coarse, but they still add charge, all modern panels work in overcast weather, our small 20watt panel has charged or kept the camper battery charged on overcast days, enough to keep it going for a number of days, our power use isn't much though, just lights and the water pump but still with our setup, 10 days has been our best so far.

We don't run a fridge though, our fridge in the camper is a 3 way fridge and runs on gas when camped.

Thanks driveshaft and Baz for your input, definitely heading in the right direction now, it's just a matter of the time to get it all done.
