What is a key requirement in NEC Article 300.44 regarding overhead conductors?

In NEC Article 300.44, a key requirement concerning overhead conductors is specifying the minimum height. This provision ensures that overhead conductors are installed at a safe height above the ground to prevent physical contact, which can pose safety hazards to people, animals, and vehicles. The code provides specific clearance requirements based on the type of conductors and the location, such as near roadways and pedestrian areas, to ensure that these conductors are adequately protected from accidental contact and to reduce the risk of electrical shock.

This minimum height requirement is crucial in maintaining a safe working and living environment, and it reflects the NEC's commitment to safeguarding individuals as well as property.

The other options address important aspects but are not the primary focus of Article 300.44. For example, while using insulated materials is essential for certain applications, it is not specifically highlighted in this article's context about overhead conductors. Avoiding horizontal runs pertains to cable management and installation but doesn't capture the core requirement outlined in 300.44. Ensuring underground placement is relevant for underground conductors and does not apply to overhead conductor requirements. Thus, the emphasis on minimum height directly aligns with the safety objectives of the NEC.
