So how many times have you heard of computers that kill - who is

I have an insulation tester capable of generating 1000 volt - there is
no leakage from live to earth or anywhere else for that matter.
What do you think, in your wisdom my earth leakage switch would do if
I had a leakage. Or how you not got such an item. I remember getting a
wife for the total som of 7s and 6pence - that does not mean she is
disposable - therefore the earth leakage switch.

As I said compliance plates are totally without value - just a public
servant con - where on earth do you work and can you earn money from
what you know?

I am long since retired and tired of paying public servant for things
they know so very little about.

You keep on about that - I have seen power supplies go up, genrally
bacause a diode has been overloaded with spikes on the electricity
supply. As long as the government allow overhead electricity supplies
we cannot start to talk of safety.

I was in one house looking at a tv with instruction to mend it -
people were short and fat and the customer did not like that despite
the fact she was like that herself.
The area was not crash hot. While we were discussing price the set
went off with a terrific bang - not so the amplifier across the road.
Everybody in the street was waiting for the young yob to burn up his
hi-fi. No such luck - he was on the same phase and should by rights
have his amplifier also go up - a simple fuse replacement cured that
whereas my customer had the set to take back to the manufacturers who
washed their hands of it. The amplifier had a switched mode supply.

Nothing stands up to a sudden 380 volt generated when electric wires
are shorted with a steelband from 1 phase to the next. Unthinking
young layabouts were caught in the next street throwing steel hoops
from brick deliveries onto the exposed cables.

There are no excuse for generating more work for civil servants
especially in an area where supplies fizzle out very gently because
they have been overloaded by the fitting of extra disks and CD drives
with no concern for the power supply.

The only real danger is the monitor with its 25volt tube supply. You
just could not make a monitor to stand up for 10 years in full safety,
compliance plate or not. When you are expecting the computer to pick
up a fax, there is no need to h ave the monitor on when it is not
viewed - so switch off and be safe.

If you cannot now agree, I suggest you get compliance plates and any
power source of 5 volts and more - especially rechargable batteries
:-)
Man you have no case - forget it.
