What is the minimum vertical distance that service entrance cables must be secured from the electrical service head?

The minimum vertical distance that service entrance cables must be secured from the electrical service head is 12 inches. This requirement is in place to ensure that there is adequate clearance to prevent physical damage to the cables, as well as to provide safe access for maintenance and inspections. Ensuring that cables are secured at a sufficient height helps to avoid hazards associated with falling debris, rainwater accumulation, or potential contact with other objects.

Service entrance cables must be installed in compliance with specific codes that outline such requirements, emphasizing the importance of safety in electrical installations. This distance helps maintain the integrity of the installation and ensures that the service entrance remains accessible and safe for both household and utility personnel.

The other options propose greater clearance distances, which are not necessary for typical service entrances as outlined in the relevant electrical codes. Maintaining the minimum of 12 inches balances safety considerations with practical installation requirements.
