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???
