For more on marking an answer as the "Best Answer", please visit our FAQ.If the appliance becomes faulty, its metal bodywork could be live. The electricity will be taken to earth through the third pin in the plug. Some appliances are built so that this will not happen. They are described as double-insulated and usually have plastic bodies. People who know more that I do have decided that they are safe enough without an earth wire.
