According to NEC Article 300.44, how should overhead conductors be installed regarding their height?

When installing overhead conductors, NEC Article 300.44 specifies that they must be installed at a minimum height above ground or other surfaces to ensure safety and accessibility. This minimum height is established to reduce the risk of contact with structures, vehicles, and people, which could lead to electrical hazards.

The requirement emphasizes the importance of maintaining a safe distance to protect against accidental electrocution and to account for various circumstances, such as the presence of equipment, high-traffic areas, and the potential for future changes in the environment beneath the conductors.

While insulation may provide some level of protection, relying solely on insulation without adhering to height regulations does not adequately address safety risks. Therefore, the key focus of Article 300.44 is on maintaining the specified minimum height rather than allowing flexible installation at any height or depending only on insulation. This ensures compliance with safety standards set forth by the NEC.
