I've got an intermittent fault on a lighting circuit that I've been monitoring for over a month.
There are three unusual things about it :
Does anybody have any further ideas before I have to start ripping up floorboards and cutting holes in ceilings !
Many Thanks
There are three unusual things about it :
- it only happens about every third day and then there are usually multiple trips over the space of an hour or so before things settle down again.
- about half the trips are between 1600 and 1800 - the other half are between 0100 and 0400 when there is no human activity and all lights are off.
- if I reset the MCB and RCD immediately they quite often trip again and usually reset on the third attempt.
Does anybody have any further ideas before I have to start ripping up floorboards and cutting holes in ceilings !
Many Thanks
