What is the minimum height above ground level for a service line attachment on a building as per national electrical safety codes?

The minimum height above ground level for a service line attachment on a building, according to national electrical safety codes, is indeed 12 feet. This regulation is established to ensure safety and accessibility, allowing for adequate clearance from objects such as vehicles, pedestrians, and landscaping, which could pose risks of contact or interference with the service line.

By maintaining a minimum height of 12 feet, the codes help prevent accidental damage to the lines from heavy equipment, trucks, or other tall objects that may pass beneath. This provision also protects individuals from electrical hazards while ensuring that the service line is safely positioned for installation and maintenance.

In contrast, the other height options do not meet the established guidelines for service line attachments, either being too low or not aligning with the standard practices regarding utility line clearances.
