Inverter s out there are 3 cables N L and PE.

I ve put all those MCB as seen on picture.

Is it ok or i should just use L for mcb and others just use wago?  Thnx

If the 2 on the RHS were a double pole you can put blue and brown through the 2 poles. If they are single as in your case then I would not. The green being earth should NEVER be broken. If broken and a fault happens and it trips you can be electrocuted.

Perhaps use a sparky to do the connections correct. Life is worth more than the money saved!

Rules are meant to be broken, also spaghetti if your pot is too small.

Measure for continuity between neutral and earth on the output. If they are connected, then probably you don't want to break earth.

There s no real earth. N n PE connected at inverter. U r correct i need to real earth n RCD. Just a smaĺl fridge s working at this system n 12v car fridge.

Im afraid to measure 230v circuits. Once blew mm s internal fuse. Is it just multimeter in continuity mode n probes one s on N the other s at PE while inverter is on?

That is what I had in mind. But you say neutral and PE are bonded... is that on the inverter output? Then no need to measure, install the RCD and don't break PE.

Your multimeter should be on Voltage, and A.C

Good day @occuplus

No intention of being harsh but with your knowledge of electricity you are a hazard to yourself and your family. Rather get a electrician that can assist and do it correct and safe. Don't be fooled by a inverter AC output it can kill you.

First of all the MCBs should be in an enclosure db to be precise. I don't see any utility input wires but neverless the earth neutral bonding needs to be done correctly. As pointed out the earth wire must never be broken, and if you need to isolate live and neutral it need to be through a double pole mcb not single mcb as the neutral should also not be broken if the live wire is still on. In other words switch the live wire only through a mcb or use a double pole mcb to switch off live and neutral at the same time. You need to add a earth leakage.

Get the wiring sorted by an electrician as it can't be left in the current state.
