This really doesn't make economical sense, tri-phase systems in residential
areas??
REALITY: 2 wires provide power, the only difference is the transformer setup
that drops down the power to your home. In the land of 110 our transformer
outputs 220V with a center tap that delivers 2 - 110V supplies or 1 - 220V
supply. (Hey, isn't that sweet....3 supplies in one, eh?).
As for the european 220V supply system......I can only guess, but you do not
have that Center-tap. And I really doubt that the electric company is going
to use 2 wires for power, then strap on a 3rd wire for grounding purposes
(what purpose would that serve, except to reference the metal toaster casing
to your bathtub water??). I'm sure the 220V tranformers have no practical
need for earth ground, since all the electronics would behave as though they
had an "Isolation transformer" on them. (That's the stepdown
transformer...outside your home).
Personally, I've heard that 110V is more dangerous than 220V......but I
don't see that as a logical argument...What.....110 has less voltage,
therefore we enjoy holding onto it longer, thus toasting us, but not the
europeans????
If anybody has an answer to why 220 is safer than 110.... I'm listening.
And that TRI-PHASE residential power supply??? Man, that is a load of
hooey....of course, the government planners weren't reaching into their
pockets, so I can assume they tapped into your dad's or grandad's wallet??

methods using odd switching type devices but extremes of design like that
would be nonsense as it would be cheaper to get the correct model. I can not
see where the smoke would be derived if you stuck this on your TV as I am at
a loss as to how you would hook it up.

America than seemingly you its residents do. North America works on 110V and
you are stuck with that, tough its not as safe and losses are greater. Now
you have a situation where you wish more voltage, you have to cheat The
mains supply is 3 phase, it is usual to run a line down a street and try to
balance the power by having house 1 on phase 1 house 2 on phase 2 etc. To
get 220V you have to cheat, you use 2 phases so a plug has 2 live's. But why
in the name of Freddy would we have to do that. Options on the back of TVs
have gone, that requires you have a mains transformer, costs money is a no
no. American TV is only viewable in America and a few other countries, the
rest of us use the PAL system a much later and superior system, it follows
then there is no requirement for your sets to work here or X. No we have
standard 3 pin plugs (flat Pins pointing at 10 and 2 with an unused earth at
