No, not fully - I only scanned it, between doing other tasks like
peeling spuds and driving the tractor round to cut the grass.
It clearly says "To ensure
that the earth connection is made as soon as the plug touches the
socket many sockets place the contact right at the faceplate, this
means that continuity is lost as soon as a plug with a sleeved earth
is fully inserted!" Hence why earth pins are only allowed to be all
brass (or all plastic if an earth is not required for the device).

Yes of course, my bad!

Fair enough.
