...Good advice,and don't start the CSI craic,until ALL standard tests have proved non-productive. I had an intermittent RCD trip,on a split way recently,no rhyme or reason,not for weeks,then won't reset,then fine...Narrowed to lighting circuit,which was both floors,a mix of old VIR in conduit,and new.It went from not resetting on a N-E fault,to a clear IR result,whilst i was jogging up and down the place. In the end,i left the MFT at the DB, IR locked,with threshold alarm set highish,and marched about some more...a tread centre of landing,upstairs,gets a beep!...carpet up,loose boards out,and there are two VIRs bent round the end of a section of displaced old conduit,which has come 20mm out from a Tee,the board slightly pressing on said item...Felt like i'd found the Golden Chalice...customer said "Oh".........so all worth it :icon12:
