Main board in the house trips maybe one every two or three weeks? The MCB that feeds the sockets on one side of the house seems to be the culprit.
If i just flip the main switch back up it trips immediately, if i turn the MCB that feeds the sockets the main switch stays up, if i leave the MCB off for 5 mins it resets fine, then a week or two later the board trips.
All sockets test fine no obvious wiring faults, disconnected all appliances etc and still happens.
Never seen this before? Could the MCB be dodgy?

Is the main switch an RCD? Is it the only RCD?
