Sorry all. O.T. as a repair issue. Just something I read about today that
I'm not sure I understand.

Anybody come across the term "step potential" or its effect in regard to a
downed live power line in contact with the ground ?


It is the voltage drop across the surface of the soil or concrete,
and if it is high enough simply taking a step will electrocute you.
There was a story about this on an Orlando TV station a few years ago
about a police horse being electrocuted in the downtown area. An old
outdoor sign had been removed, and the wires abandoned. Apparently,
someone turned the breaker back on, and it didn't trip. The officer was
on patrol when his horse crossed the path, and was killed. The shorter
the path to a good ground, the higher the available voltage is, per
step.
