No more dithering about with plugs
One of the most frequent questions I hear is
"I'm need to swap the plugs on my UK appliances to French ones, but
there's no indication which side of the plug is live or neutral - what
do I do?". Until recently this would have opened a large can of worms as
even the French couldn't seem to agree on the matter. However, I have
always had a belief as to which side is correct, which has now been
proven right.
Anyway, if you
look at the front of a French socket (assuming it is the right way up,
with the sticking out earth pin at the top), the LIVE is on the right
(or clockwise from the earth if you like). Translate that to the inside
of a plug, & it's the same. Put another way, it's the same as a UK 13
Amp plug. More to the point it's the same principal as the Europe-wide
standard (CEE17) for industrial & weatherproof connectors that most
people will have seen in the form of the blue 16 Amp plugs/sockets used
for caravan hook-ups, or the yellow (110 Volt) version used for building
site power tools. Although this standard also encompasses three-phase
connectors & goes up to 125 Amp capacity, the live connection in a
socket (viewed from the front) is always clockwise from the earth.
So,
how do I know what's right? Well, in recent times Legrand & other major
maunfacturers of fittings for domestic installation in France) have
introduced colour coding to their ranges. Lo & behold, the live is on
the right! In the absence of any more official information this move is
as good as it gets.
Whilst
agreeing that in terms fo physics the polarity does not matter it is
really bad practice to mix things up in the same installation. What
leads, adaptors etc. then do is whatever they do, but at least an
installation should be correct.
