mcb tripping indiscriminately at varying intervals between instantaneous and 10 hours,
I have a mcb that is tripping on the main ring main downstairs .
I have been all round the sockets and looked for loose wires ect . I have also unplugged all the plugs and gone to bed and it the morning it has tripped so it is not overloaded .
Can someone please explain why it could be tripping and why does it work for hours on end then just trip. I can reset it fine but it may trip straight away or wait for a few hours .
I did find a cracked socket which I have replaced but still no joy
please advise
