I bought a multiplus compact 12/1600/70 for my RV. I was under the impression this had 2 AC outputs, one for the inverter output and one that was effectively a “pass-through” for the shore power to power non-backed-up loads, i.e my fridge, water heater and space heater that all switch to gas when I’m off of shore power. Upon installing it, I’ve discovered it does not have the seperate outputs and I’m assuming I have got that confused with another model
In light of this, would this be a valid/safe way to wire up the AC side to achieve the same thing? I don’t see why it wouldn’t be, but I just want someone to double check me on the safety aspect
Note this is a very rough quick drawing, I’ll probably combine the fridge/radiator/water heater/multiplus feed into a bank of MCB + 4xRCD, and i’ll probably split the sockets into multiple smaller circuits for each socket bank (I think my van wiring is split in to two banks) - ignore the specifics of the fuses (unless something is fundamentally wrong), the main purpose of this question is the split between inverter and non-inverter loads,
To be more specific
- is it correct to have an RCBO upstream and downstream from the multiplus?
- I assume the neutrals before the multiplus and after the multiplus must be kept seperate for the residual current monitoring to function correctly?
- Am i correct in thinking I should have a higher rated downstream breaker, to account for the ~7a power assist?
- Can I put all of these breakers into the same DIN enclosure, with an air gap between “inverted” breakers and “non inverted” breakers?
