Today i did a board change was one of them all in one eicr fix on site board changes "you know the ones that always go wrong".
Well the issue was the house ring.
i had 0.44 live 0.44 neutral and no earth ring.
I have put this circuit on a B32 61009 RCBO.
now how do i stand with the earth as its not to regs with regards sizing so theoretically if a fault develops it would not carry the load fast enough to trip.
I have had every point off in the house trying to find and tightened all up but no fault so it must be a joint under the floor. laminate down so floor coming up is a no go.
i thought about putting on a 20a but there are 20 sockets covering the whole house inc kitchen. so it may over load.
i thought about splitting ring but as i cannot find the fault how can i split ill have more sockets with no earth then...
So ive gone around and zs tested all sockets i have an earth max zs was 0.73ohms and the rcbo is max zs of 1.16ohms i believe so its well within tripping times.
Any more Ideas you recon it will be ok to leave just make a note of it on cert???

Find the fault and fix it/take suitable remedial action.
You can't just make a note on a bit of paper and call it fixed!
The regulations specify that the cpc of a ring circuit must also be a ring.
Go on Pete, tell him, go on I dare you, it is a ring final circuit:tearsofjoy:

No I won't so stop taking the pess lol:mad::imp::rage: seriously though, doesn't it get your goat, when people can't even get the description of what they are talking about right?
 
I

I said stop FFS what is bad grammar? Sorry mate I really MUST read the post properly, ignore my last please put it down to the lovely bottle of wine I have just finished
Nice one Pete, are you just getting in a bit of training ready for the festive session?
 
Fully trained ready to open my present which I bought for the wife to give to me, Laphroig, think that's how it's spelt
Ah yes from Islay, I've always though it tastes a bit like TCP, possibly a good excuse if your feeling a bit peaky. Iv'e just got myself a bottle of Penderyn, from Wales would you believe! It's lovely......
 
well thanks for the productive comments. as i said i tested and there is an earth at all sockets when split i dont understand why i get no ring on the earth. i was thinking the only thing i can do considering ive stripped the entire system is to split the circuit onto two 20a rcbos. looks like thats what ill have to try and do!
there was no need for the slanging match! next time i want some friendly advice ill know to go else where!

You have had some productive and helpful comments to guide you to fixing this very simple fault. What slanging match ?
Split the circuit ? Why not just fix it ?

Quite right. Now, the Welsh scotch (!!) is excellent, but I have to take issue with the Jap stuff. I went there years ago on a business trip, and they took the greatest delight in bringing this bottle out at the end of a meal. Man it was rough as hell. Maybe its improved now, bit like the first Hondas.....

Well, I was going to recommend Yamazaki 12YO as a good accessible starting point. I have had a couple of bottles in the past and was a very good bottle in the £25-30 mark.
I've just done a search online and it retails at about £90 now though. Must have found a cult following or have limited production now.

as said in my first post its not fixable im afraid i cannot find it.
there are so many radials off the ring there must be quite a few JBs under the floor which is not accessable as its laminate flooring. if this was an easy fix i would not of asked for help!

You would treat it as a TT installation.
