Can a neon sign transformer with an output of 12000V and 30mA kill you?

calexanian:
Yes. It can..

That has been said on many occasions about supplies that are eminently capable of killing.  Any reader should not take that as an observation, not an invitation to regard them with any less respect.

Indeed -- many people have survived Russian roulette... Obviously doesn't make it safe!

Reminds me of a story about someone who found a fallen 11KV cable draped over the road through a puddle. He figured as it wasn't arcing and making a noise it was dead, so they coiled it up by the side of the road.

Power company showed up at that point, told him off and tested the cable. Yup live at full 11kV AC, seems that sort of voltage doesn't always kill you outright, can simply burn your insides up. Very worried driver left about 30 minutes later.

Yes it's definitely lethal:



The high voltage leads to ensure a very high current will go through a human, even with a pretty high resistance (ie, you don't need a wet hand as with lower voltages)

By the way, if a transformer is marked "30mA", this is a continuous rating. In the case of a short circuit, (for example through the "low" resistance of an human), it will happily supply 10-50x more -> 300mA to 1,5A.

To these lethal effects of electric current, at that high voltages and high current, the heat of the arc will burn flesh.

A coworker of me had a hole through his hand with a source that was 5-10 mA @ 5KV AC. Material defect in an isolator. The arc got through his hand

Don't play with it.

FYI, the guy in the video is really handling it unsafely :
at 0:25 he is handling at the same time both sides of the high voltage output with no proper insulation:

- The gloves are probably not rated for 12KV
- The wires are 100V wires.... Just don't.
- He is grabbing the wires. That's dangerous because in case of shock he will not be able to let go.
- He is handling both sides at the same time. Don't do that.

....no comment.
