Been to look at a lighting circuit today that tripped the mcb when the guy turned on the kitchen light presuming lamp blown he then reset mcb but still had no power. I found the mcb had failed open circuit. Never had this before - has anyone else? What would you think is the cause? No other problems on circuit or anything just curious. May break open the failed unit and see what has gone inside but was just interested. Its a GE one by the away I would say approx 5-10 years old (inspection labels pen writing has faded/rubbed off/was never there!
