Under NEC Article 230, what is the required height for a service drop above a flat roof?

The appropriate height for a service drop above a flat roof, as specified by the National Electrical Code Article 230, is at least 3 feet above the roof surface. This height is crucial to ensure that the service drop is safely positioned to prevent potential hazards, such as damage from accumulated debris or water, and to allow for safe access around the roof area.

Choosing a minimum height of 3 feet protects against physical interference and helps maintain a safe clearance for personnel and equipment that might be on the roof. Additionally, this clearance reduces the risk of accidental contact which could result in electrical hazards.

Understanding the specific height requirement highlights the importance of adhering to safety protocols set forth in the NEC to promote safe electrical installations and maintain system integrity.
