Maintenance Hole

In rural and undeveloped areas, services such as telephone and electricity are usually carried on utility poles or even pylons rather than underground.
Hazards caused by stray voltage in manholes
In urban areas, stray voltage issues have become a significant concern for utilities. In 2004, Jodie S. Lane was electrocuted after stepping on a metal manhole cover, while walking her dog in New York City. One solution is the Electrified Cover Safeguard invention, which is an on site, real time stray voltage warning system which is being used in the street lights in New York City and is also being tested by ConEd and other utilities and municipalities in England, Europe, and Japan.
