Why third pin is plastic in 3 pin plug?
Double-insulated electrical appliances, such as electric drills, only require two connections -a line and a neutral- to the supply. An earth (ground) connection is unnecessary. In the UK, all electric socket outlets have shutters that blank off the line and neutral terminals when there is no plug inserted. These shutters are operated by the earth pin of the plug. As double-insulated appliances don't require an earth connection, a plastic earth pin is moulded into the plug in order to open the socket shutters in place of a normal metallic earth pin.
