This does NOT apply to telco cables run outside, often run on the same poles
parallel to power wires for miles, grounded at many points in a MGN (Multi
Grounded Neutral) environment where, like it or not, the earth carries
Opening a shield ground in this environment is bad.
Shielded/screened TP on utility poles? This is an insane thing to
do. It violates more rules than I want to even start to think about!
Telco wires are always connected to lightning arrestors at the
termination of the long run. (This is NOT always the same as the
demarc!) MGN is MANDITORY. This is not a do-it-yourself project.
Similarly, you should not do this between buildings either! (It would
probably not be a problem running the the garage, but if the next
building is on a different transformer...You could easily melt the
wires or burn something.
Or, to put it in simpler term, "Don't try this at home, kids!". It
could prove fatal. (Hint, power lines are always at the TOP of utility
poles and gravity works.)
