micc on rcbo will not set

to day I have changed a metal cu. micc cable on to rcbo will not set. I then exchange to mcb holds. this existing circuit
tested from live to earth on micc conductor on lighting all good
What have you changed it from? RCBO detects earth leakage MCB detects Overcurrent, so swapping from RCBO to mcb tells you what exactly, not rocket science is it?to day I have changed a metal cu. micc cable on to rcbo will not set. I then exchange to mcb holds. this existing circuit
What about N to E??tested from live to earth on micc conductor on lighting all good
not seen him on here in a whileAnother topic Dave Sparks would love.
Is the cable earthed?yes westward 10 the micc is buried in the wall
I don't think rcd protection is required but he would need to fully verify that.Is the cable earthed?
When you swapped from RCBE to MCB is there a chance you could take an earth leakage reading, that may throw some light on the problem, as the problem is pointing to a leakage fault somewhere.yes pete999 tested line to earth >999 neutral to earth >999
I am asking if the neutral core is connected to the RCBO and not to the neutral bar, as if you have been swapping back and forth MCB to RCBO this could get missed.
If the light fittings are class II then there cannot be an earth fault there so there must be something else causing the problem.
Used MICC in Council new build flats in the 60s (1960s for the comedians out there)
Dark art that Pete.Used MICC in Council new build flats in the 60s (1960s for the comedians out there)
yes pete999 tested line to earth >999 neutral to earth >999
when back to day to look at the job.on to test the micc the reading went mental on IR
looked at the bathroom enclosed light the bowl was full of water & the base
the only thing was missing a gold fish . found out the flat above had a leek
went to the flat below
Dot comNow I'm really confused!
