Yes the shutter system is still required, but that's on sockets. The sleeves on plugs is for a different purpose. |
The point being made earlier was that an earth
pin must be unsleeved. As mentioned earlier (though I can't find the reference) devices that don't require an earth connection need to have either an unconnected earth pin or an Insulated Shutter-Opening Device (ISOD) in order to open these shutters.
