I had a random trip on our RCD at home.
It would go maybe once a week and then maybe nothing for 2 weeks and then 3 times in a morning.
It was eventually tracked down to a slight leak on the cold pipe supplying the header tank in the loft.
This was soaking through the fibreglass and then was either dripping down the stud wall or wicking down the cables into a dry lined socket.
I only tracked it after water started dripping from the living room ceiling!
Could have got the megger out and tracked it, but where's the fun in that?
