Have you done IR neutral to earth as already mentioned, what does the circuit supply.

Does it need rcd protection, if the circuit is MICC throughout it probably doesn't need it.

 

[buzzlightyear]

yes westward 10 the micc is buried in the wall

So go on then, tell us the N-E IR reading.....

 

[Pete999]

yes westward 10 the micc is buried in the wall

Is the cable earthed?

 

[buzzlightyear]

yes pete999 tested line to earth >999 neutral to earth >999

 

[westward10]

Is the cable earthed?

I don't think rcd protection is required but he would need to fully verify that.

So the RCBO trips, yet the MCB holds and the IR N-E is 999 - so maybe change the RCBO?

Were the lights "on" with the laps removed when you did your IR?
