A couple of years ago we had a extension that included the kitchen. The extension and kitchen were put onto a new consumer unit separate to the rest of the house. We've had the kitchen sockets trip a couple of times recently when putting the kettle on. We've moved the kettle to another socket on the same ring main and it hasn't tripped yet. I've checked the socket in question and there's no loose wires or anything obviously faulty. My own suspicion is that the boiling kettle may have been a bit close to the socket and it may have got damp so its currently hanging out to dry - though I have to admit it doesn't look damp. Before I call the pro's in can anyone advise whether my suspicion is viable or whether it could be something else? Thanks. Fred.
