The point of attachment of service drop conductors to a building shall be a minimum of how many feet above finished grade?

The minimum height for the point of attachment of service drop conductors to a building is established primarily to ensure safety and compliance with electrical codes. The correct answer of 10 feet is significant because it provides adequate clearance to prevent accidental contact with the conductors by individuals or vehicles, thus reducing the risk of electrical hazards.

This height requirement helps to ensure that the service drop conductors are above the reach of common activities that may occur at ground level, such as gardening, maintenance, or the movement of larger objects, including vehicles. It reflects standards set forth in electrical codes, which aim to protect both the electrical system and the public.

In environments where there may be variations in topography or activities around the home, this minimum height ensures a level of protection that takes into account various scenarios that could potentially pose a risk of contact with the energized conductors. This standard is established to enhance overall safety and maintenance of electrical systems within residential areas.
