Safety, Electricity and Death
1 mA Barely perceptible
16 mA Max current an average person can grasp and let go
20 mA Paralysis of respitory muscles
100 mA Ventricular fibrillation threshold
2 Amps Cardiac standstill and internal organ damage
15/20 Common fuse or breaker opens circuit
I later found this DC info...
"AC ... is 3 to 5 more dangerous than DC of the same voltage and amperage."
Slight sensation felt at hands
Men: 1.0mA, Women: 0.6mA
60 Hz AC
Men: 0.4mA, Women: 0.3mA
Painful, but voluntary muscle control maintained
Men: 62mA, Women: 41mA
60 Hz AC
Men: 9mA, Women: 6mA
"In industry, 30 volts is generally considered to be a conservative threshold value for dangerous voltage. The cautious person should regard any voltage above 30 as theratening, not relying on normal body resistance for protection against shock."
