People tell me "It's the amp load that will kill you, not the voltage".

If I say, "Okay then, grab onto the hot lead of 4160", they say, "Well...at high voltages, the voltage alone will kill you."

Can somebody explain this?

When I hear these two statements, there seems to be a big gray area of how much voltage and how much amperage it takes to hurt me. How much voltage/amperage does it take to hurt somebody? 480 at 1 amp? 120 at 5 amps? 4160 at 0 amps?

Thanks again
