Not very often, just as kids in areas that do not use the UK's BS1363

No, think metal bolt/rod or similar, that is the same diameter as the
BS fuse and you might get the idea. If an unthinking idiot can do it,
they probably will,

Again, not really comparative stats.

Again, what is the statistical evidence for this
: being a significant problem?
:

Why do you think the law was changed in the UK so that all (non
wholesale) domestic, free standing, electrical equipment has to now
come pre-fitted with a BS1363 plug and correct fuse?

Why do you thing that asking a question is a substitute for having the
relevant statistical data to compare the outcomes for different systems? If
the UK system "wasn't for consumer convenience" then your implication is
that is was for some other reason - e.g. safety. Hence arguing against your
earlier implication that shuttering hasn't any value.

I appreciate you have loads of opinions. But I was asking if you had any
reliable stats.

Slainte,

Voltage is standardized at 230v +- a fudge factor so that the UK

No, it makes perfect sense. A long time ago England was 240 volts and
continental Europe was 220 volts, both 50Hz. I don't know when this
was standrdized up until WWII France used 120 volt 60Hz AC.

(Are you sure? I thought their TV standards - even the early ones - were
50Hz-related, which would not be a good idea if they really had 60Hz
mains.)


Indeed, French TV standards were all based on a 50Hz field rate. (the French
had a 441-line transmitter operating from the Eiffel Tower before the war,
famously taken over by the Germans and operated by them for the duration.
After the war they went one better than everybody else and adopted an
819-line standard. But colour transmissions (SECAM of course) were on
625-lines. The 819 line standard was finally abandoned in the 1980s ).

In the 1950s French mains, at least in some parts of the country, was still
at 110V or thereabouts, but at 50Hz. I'm not sure when they changed to 220V
but certainly by the 1980s French mains was standardised on 220V/50Hz.


In Italy, in 1964, a friend found that his electric razor wouldn't work,
so he switched it to 110V. Problem solved!

When he finished shaving, he complained his razor seemed to be getting
unusually hot. I looked up at the nearest light bulb and noted that it
said 130V!

Correct.

Un true. In late November when there was a great big high pressure
over europe and there for naff all wind both the continental
interconnects were maxed out exporting power during the day. We just
burnt a bit more coal to provide that power. Conversly the last few
days has seen us importing from the continent, cheap, french nuke

Yes. A consequence of Merkel's knee-jerk reaction to the Japanese
tsunami by shutting down the nuclear plant and getting caught with her
knickers down when the lack of wind stopped all the windmills. I think
it was the first time that the UK had been a net exporter of
electricity.

I wonder how Germany will fare if we get a repeat performance but with
much lower temperatures all over Europe so that all other countries need

Your friend sounds confused. The 240/50 was standardised a long time
before 1970, and the various plugs and bulbs had been running on 240/50
for some decades by then.


I remember a major upgrade taking place in West Ham to upgrade the
distribution network from 215V AC to the standard 240V while I was at
school there in the late 50s.

Nearby Ilford still had 200V DC, a hangover from when Ilford town
council generated 600V DC for its tramways and obviously found it
convenient to stick to DC for domestic supplies.

When it was converted to 240V AC I do not know but there was no evidence
of anything remotely DC connected when I moved there in the early 70s.

That's because the Shuko plug is also non polarised, whereas the French

Well now, for starters there is poor retention in the socket for the Italian
plug, something for which the BS1363 design is particularly good. Also the
Italian plug is reversable, so its live/neutral polarity is a matter of
luck. Then the pins of the Italian plug are not sleeved, whilst all new
BS1363 plugs have been for for many years now.

I don't follow your logic that a safety device becomes a bad thing just
because some idiot somewhere will go out of his way to defeat it. The
overwhelming majority of BS1363 plugs are fused no higher than 13A, I don't
accept that the improved safety of the sensible majority is somehow
cancelled out by the actions of the occasional idiot.

As for your allegation that the introduction of Part P results in an
increase in the incidence of strings of trailing sockets wired with 3A cable
in hazardous areas, this seems to be another example of your notion that
safety rules are a bad thing because some idiot somewhere will ignore them.

Perhaps you might care to place your comments about Italian
electrical safety into some perspective, if it really is as
dangerous as you claim, would you like to cite a reference for
the number of electrical fires caused by such instillation
practises?

I said that I was unimpressed with Italian electrical safety, which is true.
I made no claims about statistics. What I do know is that an Italian
installation would fail a UK electrical safety check.

Only the ill-informed or idiots (those without common sense) make
something unsafe.

A comment that seems at odds with your repeated assertions that BS1363 plugs
are unsafe because some idiot somewhere might link-out the fuse!

As long as the rating of the socket or
conductor is not exceeded then there is no problem surely. I note
that you failed to specify the cross sectional dimension of
conductor used in these Italian instillations...
--

I did indeed "fail to specify" that, because I don't know what it was. But I
do know what conductor sizes were used on the flexes connected to those
plugs which was frequently 0.5 sqmm. Not adequate, I think, to handle up to
25A of fault current from a defective appliance. In the UK a flex of that
cross-section *should* be connected via a plug fused at 3A or less. OK, I
accept that many are actually fused at 13A (though less so now that new
appliances must have factory-fitted plugs) but I think that a less than
perfect safety system is better than no system at all.

On the slip side, the BS 1363 design can be very difficult to
insert/remove, the force needed can be quite high (especially for
the elderly or those with muscular problems), thus a risk of the
terminals making poor contact, also because (as you say) there is
less risk of a BS1363 plug being pulled out accidentally two
other risks are present, should the lead become stranded the lead
is damaged/parts company with the internal connections in either
plug or appliance and more importantly should electrocution occur
it is a dammed sight harder to purposely pull the appliance lead
out of the socket from a distance.

Also the

matter of

Not relevant on anything that doesn't have a single pole switch,
and surely a BS1363 plug with a figure 8 style lead is as bad,
more so because the user might be unaware of the risk of pole
reversibility? Even then, nothing to stop someone reversing the
polarity in the plug due to transposing the +/- cables. Or, and
quite possible since the EU wide harmonisation of wiring colours,
transposing the conductors at the socket.

Then the pins of the Italian plug are not sleeved, whilst all new
: BS1363 plugs have been for for many years now.

Funny that, I have such an older un-sleeved plug sitting on my
desk ATM, as I said elsewhere, there must be many millions of
such plugs still in existence and otherwise serviceable... It's
only been comparatively recently that people have been discarding
appliances still with the plug attached, the most common reason
being that it has a moulded on plug, but then these dire
contraptions have caused their own safety problems to those who
have been lulled into this fails sense of electrical safety.

If an idiot can defeat the safety device that has been place

totally OTT with its own electrical safety. You have made my

Actually I had not given Part P much thought before it was

conversation with a couple of registered electricians (thus would
get Part P registration) that Part P came up and *they* expressed
doubts over the regs effects and the likely hood of the scenario

I'm saying *anything* can and will be unsafe if miss used,

BS1363, attempts to do), does is induce complacency amongst those

Yes. The supplier I use doesn't even list unswitched 13 amp in their

Only the ca.-1960 USA version lacked the upper part of the molded grip and
the strain relief.

I'm glad someone was reading! ;-)

I have negligible experience with UK electrical appliances. I spent maybe 3
days in the UK back in the late 1980s, and that was that. Seems like a
pleasant enough place.

I spent a year in Germany in the late 1960s as a guest of Uncle Sam.

Quite, there does seem to be a great reliance on the "market
supplying" both for power and food. Don't worry if we need more X we
can buy it from the market. That's fine provided the market has any X
to sell... Power and food are finite but "the market" doesn't take
those physical limits into consideration.

But no fuse. I like the idea of putting the fuse in the plug so if
one appliance fails you don't 'fuse' the whole circuit (though with
RCDs I'm not sure that still applies).

Remember that ring mains are UK thing. The european way is for
radials so "fusing the whole circuit" doesn't have quite the same
effect. Also the fuse is to protect the wiring or appliance cable not
the appliance itself.

But how is that any different to some idiot in the UK bridging
out the fuse in a BS1363 plug and then using 3A cable to string a
large number of trailing sockets together, a prospect that has

(especially in hazardous areas such as wet areas and kitchens).

**** off, Jerry.

That is interesting for me as I lived in Stratford at the time and I do
recall some kind of change being made to the electrical power. But it was
so long ago that I'd forgotten the details.

I don't follow your logic that a safety device becomes a bad thing just
because some idiot somewhere will go out of his way to defeat it. The
overwhelming majority of BS1363 plugs are fused no higher than 13A, I don't

cancelled out by the actions of the occasional idiot.

Exactly. You can cater for a fool, but there is nothing you can do
about a damned fool.

I did indeed "fail to specify" that, because I don't know what it was. But I
do know what conductor sizes were used on the flexes connected to those
plugs which was frequently 0.5 sqmm. Not adequate, I think, to handle up to
25A of fault current from a defective appliance. In the UK a flex of that
cross-section *should* be connected via a plug fused at 3A or less. OK, I
accept that many are actually fused at 13A (though less so now that new
appliances must have factory-fitted plugs) but I think that a less than
perfect safety system is better than no system at all.

Yes, entirely agreed.

Two points:

Part P was brought in supposedly to stop people doing dangerous
domestic rewiring causing death. The most recent records
available before Part P came in (2007 and 2005 IMSMC) showed that
in that year four people had died and twenty had received
significant electric shocks as a result of unsafe domestice
wiring alterations. If ever there was an instance of jobs for the
boys this must be it.

The other issue is that continental electricians don't seem to
have any concept of live and neutral. BS4343 outlets are very
clearly marked L and N on both plug or socket but my experience
(caravanning, mainly in France) is that more are reverse wired
than correctly wired. Perhaps it is because (from what I have
seen) most Euro MCB's are dual pole and will break both both
conductors under fault conditions (remember most Euro wiring is
radial) so polarity at the point of delivery is largely academic.
I purchased a 10A two-pole MCB (LeGrand) for my caravan in a
French DIY shed for less than a 6A single pole from a UK
wholesaler. Is there any wonder we have to take more steps in our
protection chain than they do?

Nothing to do with a switch failing, it's either bulk order price

Because it can get accidentally switched off due to stuff being
