What is the minimum height for the point of attachment of service drop conductors to a building?

The minimum height for the point of attachment of service drop conductors to a building is essential for safety and accessibility concerns. This requirement ensures that electrical conductors do not pose a hazard to individuals, vehicles, or equipment. The National Electrical Code (NEC) specifies that service drop conductors should be a minimum of 10 feet above ground level to prevent accidental contact.

This height requirement helps protect the conductors from physical damage, such as being struck by objects or vehicles. Additionally, it ensures that there is ample clearance for personnel who may be operating in the area beneath the service drop, reducing the risk of electrical shock or injury.

The other heights mentioned are either below the NEC’s established minimum or do not provide adequate safety margins, which is why they do not meet the requirement. Hence, the answer reflects the necessary standard for safety and compliance in electrical installations.
