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.
