Did you not read the first post in this thread? He said it is common
to have buried cables dangaged by near by strikes. I assume "under
ground" is not the tallest thing around
The point about lightening is NOT if the object is directly struct.
There is nothing you can do in that case, a "ightening arrestor" is
kind of a joke to a bolt that just jumped across a miles long air gap.
What destroyed the underground cable is the EMP pulse from a strike
that was 100 feet away. EMP induced a current and the current was
greater then the current carrying ability of the conductor.
