Default Re: Mains plug restoration

I think that the extract that I posted is more aimed at class II double insulation situations, although that is not specified. All class II equipment that uses a plug should have a completely insulated pin in the traditional metal earth pin location. In general when you purchase this type of gear the mains plug is already moulded on to the supply cable with an insulated pin to operate the internal socket covers via the earth pin hole of the socket. These days though newer socket outlets are designed so that all 3 plug pins have to be inserted before the internal covers move. Also because the phase pins (live and neutral) are part sleeved, it should not be possible to touch the metal parts of these phase pins once being plugged in, as they are already inserted into the socket locator holes and covered before making internal contact with the socket.
