Electrical Service Pole
This is a good example of a tall electrical service poll. You
can see the clamp holding the cable to the poll can still be moved up
another foot if necessary for safety.
This electrical service poll is used for overhead utilities only. If you
do not have an electrical service poll attached to your home then there
is a really good chance your utilities are underground. Underground
utilities are safer than overhead utilities and of course cosmetically
you can't see underground utilities.
Some homeowners I have dealt with in the past don't like to look at
telephone poles and overhead utilities. I even worked for one man who
had the utilities to his remodeled house ran underground to the new
service panel because he did not want to look at the utility wires.
