No they didn\'t. The reference simply changed to 230V, so that 220V
and 240V countries could use the same, single design of 230V
equipment, designed with a wide enough tolerance to cope with the
lowest permitted voltage on 220V systems and the highest permitted
voltage on 240V systems. The voltage supplied did not change.

Here it did change. We had 220 and they changed silently to 230
without telling us anything. I just noticed that when I measured it I
read 230 on a digital multimeter (so there was no error, and I
measured in more than one house/city), and when I bought bulbs they
also said 230.

How do you know it wasn\'t accommodated within the acceptable tolerance
for mains voltage? 230 is just \"nominal\".

Just barely for the old bulbs. 230 would be OK, but the new margins
meant the voltage could go to 240, and that was not OK for appliances.
Slowly, eventually, we had to replace everything. But not possible to
claim that they failed sooner for overvoltage.

You should have got a transformer to take a bit of voltage off for your older appliances.

Pointless as modern power supplies can easily accommodate wide ranges
of voltage. They should have left it up to manufacturers to decide
what range of voltage to cope with, depending on where they wanted to
sell the goods. 100-250V (50/60Hz) for Europe and US, 200-250V for UK
and Europe, 220-250V for UK only. Some goods are/were only suitable
for the UK due to language and TV system.

Euroharmonising for the sake of it.

+1. A more useless bit of virtue signalling \'harmonisation\' the EU has
yet to dream up.

If manufacturers want to cope with different voltages and frequencies
they can. Or not, if they dont.

But it is far easier for consumers (especially if buying from another
country within the block), to just look for the 230V designation and not
to have to look at other voltages and have to look up the technical
specs and check the tolerances.

I am fairly sure that one of my guitar amplifiers has an SMPSU that can
cope from 110V AC or DC to 240VAC or DC.

Back in the \'90s, I used a (14-track IIRC) tape recorder for recording
signals from vibration sensors on a 2.5MW 11kV ExP motor. The recorder
was specified for 12 to 400V ac or dc!

There\'s a power supply circuit for electronics with a series capacitor and zener diode that will run on any AC voltage. Perhaps not efficiently.

We never lost them. In most places, the usual voltage is still around
240V. Without painstakingly checking the latest spec, the official UK
tolerance is 230V +10%/-6%, and the European is 230V +10%/-10%. [You do
the maths!] In my home, it\'s usually between 236 and 240V.

Pretty well spot on 240V here whenever I have checked.

I get 241 to 256 which is very variable, I guess the tapping changer isn\'t very fine. It\'s a new (a few years ago, replaced like for like or maybe a bit bigger) substation, but maybe the tapping changer is on the next substation up. The substation is right across the street. I complained when it went above the max tolerance, but they refused to fix it because the other end of the street would have dropped below the minimum, and they claimed going too low was worse for devices than too high. I\'m not too sure about that. I had many LED bulbs break, they could have been shit, it could have been the voltage, but they\'re all run through my computer\'s UPS now, which has a voltage tapper built in. I often see the orange LED on for \"voltage too high, reducing\". Not getting so many breaking now, but then I\'m using a different make.

Odd, you\'d think it would be easy enough to drop it to 230 with tappers. Mind you, it means we can draw less power through the cables, and they lose more power to heat through them.

tolerance is 230V +10%/-6%, and the European is 230V +10%/-10%. [You do

Why do Europeans allow a lower voltage? The devices are supposed to be designed to take a certain range, so why have different tolerances in different countries?

The fun project was a device to electrocute your friends. I\'m working from
memory but you build a box to hold a couple of D cells, that had a crank
with a gear at one end. Then you constructed a set of points with two flat
metal pieces and an insulating strip that would make and break as you
turned the crank and two girder type pieces for the electrodes. Then you
wired it up to the motor and used the inductance of the motor coil.

It was sort of a DIY TENS system.

Capacitor ladders are way more fun. You can get a million volts.

When I was little I used to play with my dad\'s Meccano from when he was
a boy.

Me too :)

I never heard of a Meccano until today. I\'m 76 and live in the USA.

I was given by a friend an Erector Set motor that he had burned out
iirc.

110v AC.

Kids playing with 110V? I thought yanks were scared of electricity.

> I took it apart and the windings were wound around a square

Isn\'t a square motor like a square wheel?

so they had 4 corners for each loop and every corner was broken. I spent
hour scraping the enamel, the paint from the end of each segment and
twisting them together, trying to use as little as possible that way
because I didnt\' want to shorten the total length. I thought that would
lower the resistance, increase the amperage and it woldn\'t work right.

When it was all done, it actually worked, but instead of wrapping it in
cotton cloth, i\'d used friction tape, cloth tape with adhesive, the
precursor to vinyl electric tape. and after 30 seconds the adhesive got
hot and started to smoke iirc. I knew it would just get worse so I
unplugged it. And I didn\'t try to recover it because I figured the
adhesive had melted and was now stuck to the windings.

The thought of buying new wire in the first place never entered my mind.
We had a nice house on an enormous yard

Why do you say yard when it\'s a garden? Yard is concrete, lawn is grass, flowerbed is flowers, garden is a mixture of the above.

but no spare money for things
like that. I got presents once a year and that was enough. No money for
projects.

When I was a kid we went on holiday to a cottage which was part of many being built. For some reason on the rough ground nearby were loads of loose bits of wire, I collected a tonne of it. Lasted me for years for all sorts of things.

And also of course there\'s the local tip, where you can get interesting stuff like old tumble dryers and take them to bits.

> I also had no real use for the motor.

I collected more motors than I ever used, ended up putting a box of 150 miscellaneous motors on freecycle. A young enthusiast took the lot.

Mine involved way more small metal parts and hundreds of screws and nuts

Never take things apart when they work. Just get more bits. Or use part of what you made to start a new project.

An RCD does not prevent fire or shorting the power source. It is only
there to protect someone in your own house from a shock. Please learn
what the different devices actually do before making such a stupid
statement.

It can prevent a fire if the fault is a resistance that heats
sufficiently connected accidentally between live and earth, at the metal
chassis, which has not sufficient current to blow the fuse.

just an example.

An example pulled out of thin air which will probably never happen. Anything producing enough heat should blow the fuse anyway, since anything less than that is the intended consumption of the appliance.

And if we didn\'t earth the chassis of everything so much would be better. Like touching a live wouldn\'t conduct through your leg to the earthed washing machine. I de-earthed my microwave incase my pet parrot chewed the flex while stood on the microwave.

Apparently those namby pamby ELCBs don\'t like microwaves, since they deliberately leak to earth. At my work, someone had put an ELCB for a large section of the building, and a single microwave tripped it. The microwave was functioning just fine, but this stupid breaker kept cutting power to a large number of offices. They removed it.

Why do people keep changing the names? It was always Earth Leakage Circuit Breaker. Now we have RCD and GFCI. WTF? They mean the same thing! Stuff goes to earth and it switches off.

I remember a friend had been given a pair of field telephones which used
hand-cranked magnetos to ring each other. He wired the magneto to the
aluminium loft ladder and to a bit of tin foil on the floor of his
bedroom (*) and turned the handle as I reached the top and instinctively
put my hand on the foil. I nearly fell down the ladder. What a jape ;-)

Moral: be suspicious if you see a strange bit of tinfoil, and hear a
frantic winding of the magneto handle and suppressed laughter - and
don\'t go up the ladder in bare feet. I\'d guess those magnetos produced
about 80-100 V - a nasty belt :-(


(*) When his sister was born, his dad converted the loft into a new
bedroom for my friend, reached by a retracting loft ladder past which
everyone had to squeeze to reach the bathroom and separate loo. It
stayed like that for as long as I knew him afterwards - no room for a
proper staircase.

I collected more loudspeakers that I knew what to do with - from old
radios etc. I also found a really good one in a wooden soundbox, at the
local tip (*), and connected it by a long length of GPO telephone \"drop
cable\" that the GPO man gave me when he changed the cable from the pole
to the house due to crackling on the line.

So I had this speaker in the garden shed, fed by the GPO cable from
dad\'s record player - I must have driven the neighbours mad.

I also went armed with a screwdriver whenever we went on holiday, and if
I found a derelict car in a \"car dump\" (**) I\'d remove the speedo and
switches. I mounted a Ford Anglia speedo with the cable connected to a
Meccano motor, which was switched on and off by a Mini ignition switch
(using the key number stamped on the switch). The Anglia speedo thus
registered about 50 mph when the key was turned on. I also had a Mini
headlamp as the main light in the den that I built in the loft, and
another motor to raise/lower a cardboard gullwing door on the den. All
powered from a mains-to-12V transformer.


(*) Near where we lived, the council used to put out a couple of skips
in a layby for people to dump anything they no longer needed. People
were always rooting through the skips, Womble-like, to nab anything that
looked interesting from the \"things that the everyday folk leave
behind\". Wouldn\'t be allowed nowadays: all skips have to be supervised
rather than just being left unattended, and taking things from skips has
been criminalised: even though someone has left an object there to go
into landfill etc, it is still deemed to belong to them and to be theft
if you remove it.

Incidentally, and I kid you not, there is a recycling centre in North
Yorkshire at a place called Wombleton:
https://www.northyorks.gov.uk/wombleton-household-waste-recycling-centre
- how very appropriate.


(**) A scenic little valley just down the road from a caravan site where
we were staying had been used as an unofficial car dump and there were
various Minis, Austin 1100s, Cortinas and Corsairs loosely stacked. It
must have been incredibly dangerous for me to go clambering over and in
these cars, but no-one really cared. My dad even helped me. I remember
being very proud of the \"knee-capping stalk\" from an early Ford Consul
Cortina/Corsair (pre-Aeroflow facelift) - this was a metal (or else very
hard plastic) tube that stuck out from the steering column with tab
switches for indicators and lights, and a button on the end for the
horn. In an accident, it was ideally placed to take your kneecap off :-(

why the new tunnel the Germans are building couldn\'t go right
underground and had to be installed on the bottom of the ocean,
because the pathetic toy trains couldn\'t handle the incline. This is
the 21st century, we have cars. Public transport is for chavs.

If there were no friction between train wheels and track acceleration
and braking wouldn\'t happen.

The reason railway tracks are so level is so that the engines can have
the minimum power to pull the train. Very steep inclines would require
extra locomotives to be put on to get up the hills.

Steam locos were not rated in horsepower, but \'tractive effort\' . How
many tons of pull they could generate before the wheels slipped.

That\'s why they had a lot of driving wheels - at least four, generally 6
and up to 8.

I suppose this assumes that the tracks do not bend, vertically or
horizontally, or some of the wheels could loose pressure, as there are
no springs on the loco wheels (but the wagons do have them, so there
must be imperfections on the tracks).

Why were they never made of something more grippy than highly polished steel?

The Mount Ranier museum has a working Willamette but they shut down during
the covid panic.

ROFL, there\'s still people wearing masks here. I went to hospital with a suspected broken thumb and everyone had a mask on. They glared at me sternly when I refused.

And here.

I did too, to get a skin cancer removed.

The reception staff didnt, but all but me of the patients did.

No one said anything to me, including the surgeon and he wasnt wearing one
either.
Just an initial consult, he hasnt done anything yet.

TYPICAL retarded \"conversation\" between sociopath Rodent and sociopath
Birdbrain from August 26th 2018:

Birdbrain: \"I have one head but 5 fingers.\"

Senile Rodent: \"Obvious lie. You hairy legged cross dressers are so inbred
that you all have two heads.\"

Birdbrain: \"You\'re the one that likes hairy legs remember?\"

Senile Rodent: \"The problem isnt the hairy legs, it\'s the gross inbreeding
that
produces two headed unemployables like you.\"

Birdbrain: \"So why did you mention hairy legs?\"

Senile Rodent: \"Because that\'s what those who arent actually stupid enough
to shave their legs have.\"

Birdbrain: \"You only have hairy legs if both of the following are true:
1) You\'re quite far back on the evolutionary scale.
2) You haven\'t learned what a razor is for.\"

Senile Rodent: \"Only a terminal fuckwit or a woman shaves their legs.\"

Birdbrain: \"There is literally zero point in having hair all over your
body.\"

Senile Rodent: \"There is even less point in wasting your time changing what
you are born with.\"

It is, however, their business if the electrical problem
causes a fire that burns down half the town, or takes out
a condominium project or flats.

An RCD does not prevent fire or shorting the power source. It is only
there to protect someone in your own house from a shock. Please learn
what the different devices actually do before making such a stupid
statement.

It can prevent a fire if the fault is a resistance that heats
sufficiently connected accidentally between live and earth, at the metal
chassis, which has not sufficient current to blow the fuse.

just an example.

An example pulled out of thin air which will probably never happen. Anything
producing enough heat should blow the fuse anyway, since anything less than that
is the intended consumption of the appliance.

And if we didn\'t earth the chassis of everything so much would be better. Like
touching a live wouldn\'t conduct through your leg to the earthed washing
machine. I de-earthed my microwave incase my pet parrot chewed the flex while
stood on the microwave.

Apparently those namby pamby ELCBs don\'t like microwaves, since they
deliberately leak to earth. At my work, someone had put an ELCB for a large
section of the building, and a single microwave tripped it. The microwave was
functioning just fine, but this stupid breaker kept cutting power to a large
number of offices. They removed it.

Why do people keep changing the names? It was always Earth Leakage Circuit
Breaker. Now we have RCD and GFCI. WTF? They mean the same thing! Stuff goes
to earth and it switches off.

I suggest you read up on how a RCD Residual Current Device works, ELCB
are rather olde hat now.

An RCD measures the current flowing on in one wire and that going out on
the other as long as they are in balance, then all fine.

However if they are not then they will trip. That is caused by some
current leaking to earth somewhere that could be a simple leakage fault
such as a heating element breaking down or it could be through your body
not good!

Its simply stupid to un-earth things like microwaves and the like what
if they developed a fault with current was leaking to the metalwork of
the unit that would then be live and is then capable if a shock not
pleasant! i had one once very very painful and I couldn\'t let go thats
the worst part this was in pre RCD days!

It is possible for a large number of PC\'s on one ring main to cause a
trip to go but it has to be quite a lot as they have capacitors in them
which are from live to earth and will introduce some leakage usually
much less then that the 30 ma RCD is designed to trip at.
