Hi All,

I recently had an electrical issue where the live and neutral shorted out at the pole outside the house and it got me digging a little deeper in to my home DB.
I'm no electrician, but I have a pretty good understanding of how wires should be and I like to know exactly what's happening in my house considering it's an investment.

I have a pretty old house, that has two phases coming in and a neutral.

Currently the Main DP switch breaks these two phases and then the neutral goes straight to the Earth Leakage.
From what it looks like, one phase goes to the Earth Leakage, the second goes to the Light Arrester.

The Earth Leakage phase (P1) then provides power to the plugs in the household and the Light Arrester phase (P2) provides power to the lights, geyser, stove and Sub DB (Gate/Garage).

This seems a little off to me, but as I said, I'm no expert here.

Should I be getting a 3 Pole Main Switch to break both phases and the N?
Should I have a Leakage Switch for each phase individually?

Of course I'll be pulling in my electrician to do all the wiring correctly, but I'd just like to understand how it all should work as well.

Thanks in advance,
Cheers
