For a van conversion.
Is 40A Breaker on 6mm2 pushing it a little?
Diesel Heater is on its separate circuit, for safety.
No RCD/Consumer on multiplus shore inlet, I've heard this can cause headaches.
One thing I haven't drawn yet though.. I was considering charging the starter battery from the multiplus trickle, would that be any more complicated than just joining it to the starter battery positive?
