I know that a elektric shocks are very different from case to case . Can i be shure that the HV is absolute lethal when i am not one out of a million.

My technical Conclusion is, that most HV powersupplys were not capable to be driven to 20mA constantly, but have enought energy in the Caps to output a much higher current for a short time. And Because the Chassis is not floating the Human Body is always enought earthed to be a good conductor.

Hello

I'd bet on Lethal, especially if someone had a heart condition.

The question is not if it can be lethal the question is how lucky do you feel today ?

A lot will depend on the person as well, their sensitivity to shocks, and their skin resistance. Me, I've been zapped so may times, I have no problems sticking my finger into a live light socket to see if there's power. My first installer was so sensitive to being zapped that he had to take the day off twice to recover.

And no, he wasn't faking it.

I don't think its any worse than being zapped by a cars ignition; which are also 35K to 50k volts. It certainly is uncomfortable, definitely not pleasant, but easy to shake off after a few choice words.

Electric fences are also quite a high voltage. Its not the voltage that is the killer, its the current flow. Anything over 50 volts AC can be fatal if there is enough current flow. It can take as little as 120mA to bring on cardiac arrest.

Im sure youll read 100 different claims on 100 different pages. I was refering to current taking a path across the chest, not connected dirrectly to the heart. 120mA is the figure i have to enter into the written test to pass every 6 months. You know as well as i do its a mystical theoretical value and varies between people based on alot factors.

Here we have a different electrical supply system to you in that we use the MEN system, our residual current devices have a rating based on intended use, as a quite rule, 10mA for medical, 30mA for domestic and light comercial, 100mA for industrial. Thats only a quick run down, there is alot more to it than that. 30mA is the most common value, and the value used in almost all homes on lights an power circuits

My 2 cents
There is a current range that screws up your hearts rhythm; I was taught that 80 to 120 ma is the dangerous range. Above that range your heart clamps up, below that range not much happens. I have to wonder how a theory like that got tested empirically.
My work involves the common 208-416-575/3/60 and I hate getting shocks. Unlike the power supply in a pj these supplies can deliver a lot of current. There's a reason it doesn't feel good. That's your body telling you not to do that. Don't dwell on how much voltage you can get away with touching, just be grateful you survived the last shock.

You do not want to put both hands into any HV device at the same time. If you get whacked, it passes right through your heart NOT GOOD.

So do like Curt does, one hand in the projector and the other in his pants and you'll never get into trouble Laughing

Then if you do get a shock, you won't need Viagra for a while Mr. Green

No... You probably wont need anything, youll likely be black balled
