My 3 wire drop comes from the telephone pole in my back yard, across my yard,
to a metal pole on my house. Through this metal
pole
the 3 wires enter my house to my inside fuse panel. Should I ground this
outside metal pole to an outside earth ground rod, and
connect
it to my tower grounds ?
Confused,
