I am in final stages of setting up 2 x Multiplus II 48/5000 in parallel and just need some advice on wire dimension and MCB/RCBO setup.
I plan to run 10mm2 Twin-Core+Earth from 240VAC Grid/Mains to MCB 50A, 10mm2 Twin-Core+Earth from MCB 50A to each Multiplus 48/5000 to AC-IN (Same cable length and size)
Grid/Mains connection is for backup power and battery charging if required.
Not sure what cable size I should run from each Multiplus AC-Out to a 40A RCBO then to House supply, suggestions welcomed. I do know cable length and size needs to be the same to keep same resistance etc.
Thanks
