How hard can it be to put some kind of
electronic limiter on a power tool so if
you over-stress it, it doesn't consume
enough current to melt the coils?

I assume something like this must be done
on electric cars, or instead of stalling
the engine, you'd wreck the motor.

Most motors that are to be used unattended
do have thermal overloads in them. I guess
hand tool manufacturers assume you will stop
before you burn up the tool

I've been on construction sites where I'd
cringe when I heard workers abusing both
hand-held and table saws. One
of the things I was always
repairing/replacing were the power cords on
circular saws where some genius carpenter got
it caught in the blade.

I did that with a hedge trimmer once.

You folks use 220vac 50hz as I recall. Did you
have a lot of sparks or did the fuse blow
immediately? o_O

[8~{} Uncle Fused Monster

The only observation I made was the trimmer
stopped running. Of course I had a proper 3A fuse
in the plug, not the 13A standard everyone seems
to use. And no I don't have any form of circuit
breaker, earth leakage or otherwise.
North american stuff doesn't have fused plugs.
We fuse the feed circuit.

But you might have a table lamp or a heater plugged
into that circuit. In the UK we fuse according to
the appliance. It also means we don't have to run
a seperate wire to every ****ing outlet.

Is that why your plugs are so damned large?

They're an easy size to get hold of. Your mickey
mouse ones are pathetic. Do you have tiny little
hands or something?

And we had them that large before fuses, it ain't the
fuse that takes up the space, it's because they can
take 13 amps. Over 3 kilowatts on any device we
like, no need for special circuits with different
currents and voltages, just one standard plug and
socket for anything you like, anywhere in the house.
I can plug a computer, a lamp, a hairdryer, a vacuum
cleaner, or a clothes dryer into the same outlet.

OK, I undeand. Apparently at some point the US
considred convertng to a system similar to that in the
UK, but because of the already existig proliferation
of both low and high volage devices, wiring, sockets,
and plugs in the US, it was deterined impractical.
At that point in time, there was not such a
proliferation of such devices in the UK.

Why would it be impossible to make all your future
plugs the same, but containing a fuse? And you could
gradually move over to the higher voltage too to
simplify things. New appliances could run on the higher
voltage, in fact switched mode power supplies would run
on either.


I never said it would be impossible, but at this late
date it would probably be economically unfeasible given
the millions of devices from generating stations down to
single households. I'm also not suggesting that either
system is better or worse than the other. What works in
either country happens to work and no one on either
side of the ponnd seems to have a problem with their own
system. Personallhy, I don't really care. I was only
curious some physical attributes of the UK system.
Back in about 1954? Ontario Hydro decommissioned the
old 25 hz
system in the remainder of Ontario to switch up to 60 hz.

This required the replacement of all induction motors,
ballasts and clocks in the affected area. At that time it
was a major hassle, but not a disaster, due to the
relatively small number of induction motors and
flourescent lights in use, as well as clocks.

Can you imagine a changeover of that magnatude today?
Particularly changing operating voltage - which would
require changing anything with a transformer, a universal
motor, a light bulb, etc AS WELL as the inductionmotors
and ballasts which needed to be changed for the frequency
shift???????

It would be a MAJOR disruption to ALL life in North
America.

To say it wouldn't be impossible is pretting a pretty
litteral and restrictive definition to the word.


At that time they did not decommission all the 25 hz
generators - they installed HUGE rotary frequency
converters which have only now been decommissioned with
the overhaul od the last generating stations - with some
industries in New York STILL running on 25 hz up untill
the conversion in 2006? when the 25hz generators at the
old Rankine station were decommissioned.

But it isn't a sudden change in voltage. 240V is already
in all American homes. You just move stuff over as you buy
new things and use the higher voltage instead of the centre
tap. Eventually the centre tap is obsolete.

Why don't we just convert all our cars to run on diesel
because you say that's better too? Makes as much sense.

No, making all *new* cars use diesel would make sense. It's
more efficient.

The underlying fact here
is that there is no problem that needs to be solved. 120V
works just fine.

But you've got more than one type of socket and more than one
circuit on the house. It's pointless.

Have you been here to a typical house? I have a 3200 sq foot
house and every receptacle is the same, accepts the exact same
plug, with one exception. That's the dryer which has a 240V,
30A receptacle, which supplies 2.5X the power you can get out
of the receptacles you say you have. I'm like most people, I
don't move the dryer around, don't need to plug use it in the
living room or bathroom. It stays in the laundry room, plugged
in there.

And big portable power tools? What about the washing machine
and the dishwasher? You never redesign your kitchen?

As for "more than one circuit", I would assume you have that in
the UK too, unless you're now telling us everything is on one
240V 15A circuit.

More than one TYPE of circuit, do I have to spell everything out
for you?

Here's an idea. Almost the whole rest of the world drives
on the right side. Why don't you convert? It's easy. Just
do it a street at a time, having cars drive both on the left
and right while making the transition. They could sell new
cars with the steering wheel on the left, and just evolve
over time. It would be easy.

That's nothing like the same thing, you're seriously **** at
analogies. You're currently driving on both sides of the road
with two voltages. Im suggesting you gradually move to one of
them.

It's exactly the same thing. Being right drive obviously works
for you. But, heh, I don't like it. So, you should change and
be like almost all of the rest of the world. Just like your
crazy idea of rolling out new household appliances that are
240V, rolling out cars that are left hand drive should
similarly be no problem, converting over highways, little at a
time, should go just swell. So, get on with it already!

Look ****wit, the analogy is fatally flawed. We drive on ONE
side, you drive on ONE side. But with electrics we have ONE
voltage and you have TWO. It's not about CHANGING voltage, it's
about phasing out one of them.

Easier said than done! Period!

But it isn't a big task, you just do it gradually. Start putting
in some 240V outlets in new houses, make new equipment take the
higher voltage. Make adapters, whatever. Aren't your 110V
outlets actually split phase so you can just replace the plate
with a single 240V socket and ignore the centre tap?

I'm not sure, and I'm too old to care. All of my lights, small
appliances, and electronic gear work just fine the way they are.

But you can't plug up to a 3.1kW device into any outlet you like anywhere in the house. Power tools, fan heaters, kettles, irons, two things on one adapter, there are so many things that half the power just ain't enough for. It's so much more convenient in the UK to be able to power anything in any room from any socket.
