Its a little rich for someone in the US to complain that *our*
electrical systems are unsafe... You only need look at the electrocution
stats where they have annual death rates of thousands a year compared
with the "tens" per year we would expect here

I heard that with 110V it is recognised practice to test for live
using one finger. Is this apocryphal?

No. I had to administer first aid to a US installation engineer being
trained at our facility in the UK who used that approach on UK mains. It
threw him across the room knocking the wind out of him entirely. After
the incident a warning was added to training materials never to do this!

Warm sweet tea aided his recovery but he was lucky not to be more
seriously hurt. One of my friends at university got hold of the wrong
end of a Jesus lead with serious very burns to his hand resulting.


Do you know many years ago now i used to work in a TV repair shop and we
used the Philips monochromes chassis which were notorious for blowing
mains dropper resistors the repair was to solder a large wire wound
resistor across the open circuit sections. We use to wrap it round with
pliers then solder it with a large instant heat gun, this was often just
had its wires to where the mains came into the TV.

Back then the TV chassis was likely to be at live mains potential on
the TV course back in two pin plug days and reversible connectors it was
quite often the done thing to have the whole metal chassis live.

No one ever got a bad belt but a tingle plugging up the aerial
sometimes;!..
