Sanity check - replacing MCBs with RCBOs

Underground. Nearest substation is about a mile or so away.

To the OP, I don't think for one moment that you're being serious, but just in case you are, I've spent most of my life flying all over the world doing electrical and related work, pm me if you want to book a slot in my diary. As I remember, HK has this strange blend of UK and Chinese methods, and I'd guess that even now most work has to be done to UK standards to conform to what existed before?

I'll send you a pm.

That board is a mess mate, it backs up my statement earlier that your electrician friend is not what he claims.
My offer still stands, I'll compromise and travel business class but you'll be left with a safe, easy to use installation at the end of it

Trev, for my understanding what is wrong with that board? I can see the neutrals and earths for the rcbos need tidying up but other than that are there other fundamental issues that should be addressed?

The thing is there's no guarantee that when there's lightning it won't take out all the RCBOs. There's a reason why tripping happens and that is what needs to be found.

Yes, I can see what you mean. Is the solution to fit something like this to each board?

Well the way the top row has been fed leaves an awful lot to be desired, the cabling needs a damn good tidy up. There could also be further, more serious issues in there but only time and testing would prove that.

Surge protection may well solve the problem but as I've said earlier in reply to another poster it could be something as simple as something else is getting wet but only someone with proper test equipment and the knowledge of how to use it could tell you that for definite

Thanks Trev

A bit like having a hole in your bucket, if I could find someone competent I wouldn't be in this mess in the first place.

Well if post #42 means what I think it could then you've found someone more than competent mate
