[QUOTE="Ardet R, post: 474008, member: 30040"] If the kettle electrics have got wet then there would be a fairly high resistance path from Live through the water and so to the body of the kettle. A high resistance test meter might measure 240V from the kettle body to a good earth such as a sink, not usually just the water on the counter, as there would be no current flowing and so the resistance would be immaterial. When you touch the kettle casing a small current will flow through the body and you will feel a shock but the current through both the water and the body would be very low in the 10-100 mA range as the resistance of the body and the water will then be significant. However if you were in bare feet on a wet tiled kitchen floor laid on the earth then the current could be much higher in the 200-1000mA range enough to cause death, but never enough to blow the fuse. The fuse is only protecting the cable from overheating and burning, not people from being electrocuted, By now any socket circuit ought to be 30mA RCD protected for just this reason, the RCD would then trip on you touching the kettle and whilst it would still hurt it should not kill and would not happen again as the circuit would be off.
