Had a look at a job where the cooker, protected by 100mA rcd, trips intermittently. Sometimes it can go for weeks without any problem.
The cooker is only 2 years old. I have carried out an insulation resistance test on all the cables which was >999 and also a ramp test of the rcd which trips at 85mA. Pulled the cooker out and checked all the connections which are fine. What I did discover was a brown coloured like grease behind the cooker on the wall and on the cooker connection plate which I would assume is from moisture.
Anyone any ideas as all I can think of is moisture which is causing it to trip.
