I had a RCD tripping before when some incidents were related to water ingress, and MCB tripping with appliance faulty/misuse. Today, when I was using 2 hobs, an extractor fan and a tumble dryer at the same time, I experienced both MCB and RCD tripping. There was no prob for me to push MCD and RCD back on, but I am still very nervous. What might cause both MCB and RCD tripping, overload, damp, or short circuit?
