I agree; it is unlikely, and a second error resulting in a shock
multiplies the improbability, but the consequences could be fatal, so it
is a matter for debate. It is practicable to eliminate it; the distance
from the centre of the earth socket to the edge of the enclosure must
exceed 21 mm.

You have misunderstood. The effect occurs with extension cables, usually fitted
with four sockets in a line. It does not occur with wall sockets, even
surface-mounted, because the sockets are large enough to prevent

Well, strictly, an electric shock incident would be a 'two-fault'
situation - plug reversed AND conducting object inserted into the live

Dear Johns,
Thanks for advice abt other countries using 13A plugs & sockets! Do they
require specific approved bodies for issuing certification like UK?

I call this a “solution by successive approximation.” :-D

I believe that no-one thought of the possibility of a design that
allowed that incorrect insertion. It is known to the responsible BSI
committee, but of course it takes time
with such design if it meets
the standard.
According to LVD guidance, this type of product falls into LVD, not GPS. John,
how does this product relate to GPS?
