you can grab a cheap am radio, remove the cover and even just poke around
at the parts while it's on.

Battery powered of course, if poking with your fingers!


haha, yes.

So what does mains shock feel like in places with 240?
Hmm, it hurts..

It makes you see stars, and makes your muscles contract violently.
And there might be a small burn mark.
Having good quality plastic soles under your shoes makes single contact
oke. Dont use leather soles.
My limit fo far is 2X500 volt from a falling radio I tried to catch.....
We both survived.
Automatic reflexes are so dangerous when you work with electricity.

Interesting.

Here in US with 120, the danger is almost always from what you end up
hitting or falling off (like a ladder) /into than from the shock
itself.

I've never been burned from 120 or seen stars or anything like that.
I've touched high voltage DC equipment where it doesn't even matter if
only one hand is in the pocket or or anything like that. At 8kV you're
getting a one handed shock unless you have special boots on.

The last actual line voltage electrocution story from around here was
from somebody running an electric drill outdoors on a hot day. They
sweated into the drill, couldn't let go and died.

Possible, but I suspect an urban legend.

How often do people drop dead from actual electrocutions in places
that use 240, just doing plain tasks like you might at home or
outside?

People do die from electrocution on 240 volt AC mains. More often than
not the reflex action causes you to pull away. I agree with your
comment that "the danger is almost always from what you end up hitting
or falling off (like a ladder) /into than from the shock itself."
DC is far more likely to kill you, simply because the muscle contracts
and makes it impossible to let go.

Is it 240 from either side of the line to ground, or how does that work? I
asked all about this when I was in Ireland, but forgot the answer.

No,1 phase and 1 return.

The return is actually the centre tap of the 3 phase system(3 X 240 V),
and equivalent to ground.

So it's usually some sort of Wye connection where one side of the power
would in theory br safe to just touch if you were standing in a puddle?

What's confusing in the USA is the mix of 120/240 and then the 120/208
circuits from 3 phase power in larger settings.

So while most homes may have 240volts available, an office building may
only have 208 between any two legs of the three phase power they have.

For a computer, it doesn't really matter, but for things like induction
motors, it's more of an issue.

AC can do that too, My dad had trouble putting a skilsaw down after
cutting the lead. luckily he was able to out-distance the extension
lead. Next time he used it with an isolating transformer.

Normally the centre tap is bonded to earth at the distribution
transformer, such that the Neutral and earth are at the same potential.
The Blue, Yellow, Red phases supply the 240 volt feed. Often you will
find that one side of the street is one phase and the other side of the
street is another. They do try to balance the phases by connecting
equal numbers of homes to each phase. In the UK its rare to have a
domestic property supplied with all three phases.

What's confusing in the USA is the mix of 120/240 and then the 120/208

Hi Rui. Electronics is a deep and wide river. Some folks like the
analog part which has the audio stuff and the rf stuff. Others cant
grok analog, but they love the digital stuff. I'll second the
recommendation of getting your own copy of The Art Of Electronics.
Having a nice home 'lab' is great... a meter, power supply, signal
generator, used scope or a pc scope, those white proto boards, and a
blue box of drawers with opamps, resistors, capacitors, leds. The
light bulb came on Real Bright for me as I turned the gain pot on an
opamp inverting amplifier and watched the output sine wave get bigger.
Then I turned the offset pot and the whole wave went up and down. When
it hit the top and bottom it clipped, and sounded like crap. Really
need the scope in my opinion. Good Luck!

Yep. RF burns are kinda painful too. But I bet it doesn't compare with
that infamous second anode. That one will make you change your shorts
for sure. That is if your still able to. Hit one of those when I was
in high school. Haven't touched a TV inside once since.

Thanks in advance,

Become a part of a forum and mingle with other hobbyists.. It's helped
me.. I'm a member at http://www.electro-tech-online.com and everyone
there will help you with anything you need.. Also, if you want to
start building some fun circuits buy a breadboard and start making
some simple circuits, a great site that has some fun circuits is

How often do people drop dead from actual electrocutions in places
that use 240, just doing plain tasks like you might at home or

People do die from electrocution on 240 volt AC mains. More often

not the reflex action causes you to pull away. I agree with your
comment that "the danger is almost always from what you end up
hitting or falling off (like a ladder) /into than from the shock
itself." DC is far more likely to kill you, simply because the muscle
contracts and makes it impossible to let go.

AC can do that too, My dad had trouble putting a skilsaw down after
cutting the lead. luckily he was able to out-distance the extension
lead. Next time he used it with an isolating transformer.


Nasty ! I'm glad he's OK. I use a GFI on power tool cables.

Didn't have them back in 1975, plastic power tools tools were a
rarity too.
