I smirked at the comment ...
Anywhere from 118 to 120 volts and zero to 500 amperes ran through the wires in the malfunctioning utility box, power-company workers said. One
worker estimated that 200 to 300 amperes shot through Lane.
Although the incident is tragic, the actual facts are misleading I believe.
Looking at the picture of the repairman at the actual box doing repairs, it looks like no more than a street lamp pole post or a light signal pole
It only takes about 600 milliamperes to stop the human heart. If there were about 300 amps going thru the dogs or the woman, she would have probubly
burst into flame. Amps do not jump out. Amps are the force of the voltage going thru the resistance. A human body naked has over 1 Megohm resistance
top to bottom dry. Even if wet the voltage would likely travel the surface of her skin to find ground, mostly bypassing the heart. At 120 volts it is
very unlikely that 200 amps of current flowed thru her. More likely it would have been maybe an amp or two.
If that is a light pole or street light, it is very unlikely that there is more than 30 amps of current flowing thru the wires, and if the wires were
still connected, the brunt of power flow will still go thru the wires, even if you stick your toung on it.
The pole obviously metal, should by all means be tied to earth ground, and the failure was probubly a chaffed insulation on the hot wire touching the
metal box. If the ground connection had not failed, this would normally blow a breaker or fuse, but if the ground failed, then the metal box would be
at line potential, 120 vac. If she did touch it, she may have drawn enough current to kill her, ...but not 300 amps! Probubly an amp or two.
Yes the source wire may be able to 'provide' 500 amps, but the resistance to draw this would have to be very low, like one or two ohms, not the mega
ohms that probubly existed when this happenned. One or two ohms would be the equivelent of a metal shorting bar, dropped directly across the circuit,
which she wasnt, she was just additional circuit resistance.
