Electrocution: Are there any PSU's that provide mains voltage to a computer?

I'd rather grab a chainsaw than the mains.
I'm not saying it isn't dangerous, what I'm saying is it is unlikely you'll come to any harm, if something untoward did happen. For every 2.5 million schocks 30 people die, and having had quite a few electric shocks myself from the mains I can testify to the fact that if it does happen, you'll probably be perfectly OK, which is more than I can say for slipping with the kitchen knife.
The comparison is not touching a live mains wire and using a chain saw. The comparison is using a chain saw and using a voltmeter on an electronic device. A voltmeter has plastic leads so even if you did touch something that you shouldn't it would be the voltmeter that would cop it. In fact the fuse would blow.
So is it dangerous to touch a mains lead ? ...well you'd be unlucky other than to have a bit of a shock. Is it dangerous to use your voltmeter on some electronics?....noLast edited by BlasterBates; 8 October 2012, 14:55.I'm alright JackComment

Brushing a wire maybe. But grab hold of something, that's pretty bad news! At best you'll get thrown across the room.
This is assuming you don't have a proper circuit breaker... with those it should be safe to grab a live wire and IIRC my father tells me salesmen used to do just that when the modern ones were cutting-edge.Originally posted by MaryPoppinsI'd still not breastfeed a naziOriginally posted by vetranUrine is quite nourishingComment

Pre circuit breaker days I forgot to isolate the electric shower before changing a valve. Left hand touched the pipe and right hand on the live. It did not throw me but it jerked my arms violently.

I suspect most of the injuries are caused by children sticking wires in their mouths or electric shocks in the bath, which are dangerous.
I'm just saying you would very unlucky, if you were to use your voltmeter and you accidentally tried to unscrew a live connection (which is basically how I got the electric shocks when I was doing my project at Uni).Last edited by BlasterBates; 8 October 2012, 15:36.I'm alright JackComment

No burn just a shock. I think you are thinking of KV electric shocks. In fact some kids grab hold of main live wires as a dare. I'm not saying this is a good thing, I'm just pointing out that 99.99% (according to the statistics, i.e. 2.5 million shocks and 30 deaths) nothing much happens.

get an RCCB. its worth it for peace of mind. have extra plug in ones for external tools the further you are from the earth the less sensitive they are.Always forgive your enemies; nothing annoys them so much.Comment

If you electrocute yourself with one of those in circuit does it mean you'll only feel a tickle?Comment

when I used to build power switchgear I worked with a guy who took 240V to ground via his arm after leaning on a bus bar thinking something was switched off when it wasn't, he had some pretty serious burns.
Oddly noone wanted to work on site with him.While you're waiting, read the free novel we sent you. It's a Spanish story about a guy named 'Manual.'Comment
