How Long Does Before Being Killed?
How Long Does Before Being Killed?
(OP)
Most people know that current determines how damaging getting shocked can be. A question was recently asked which I do not know the answer to. The question is, how long does the current have to exist before someone sees the effects.
For example, 100 to 200 mA can be fatal. But how long does this current have to pass through the body? What if it exists for only 1-2 cycles?
I believe a GFCI trips in less than 2 cyles. Since this device protects people, it would seem that 2 cycles of 100mA may not kill someone.
Any help is appreciated. I would also appreciate any references that can be provided.
Thank you

IB = 0.116/sqrt(ts)
for a 50 kg body weight
IB in amps, shock duration ts in seconds

t(s) =(0.116/IB)2

Bit of hard luck if you have just done a 500m sprint and then touch a live conductor. So never rush to job is my advice.

30mA in the UK, 10mA in high risk areas.

2 cycles @ 100 - 200mA probably wouldn't be fatal. But again, depends on the indivule.
Also, sweaty skin can make a huge difference in the amount of time it takes for the outer skin to break down.
