What is the primary focus of NESC rules?

The primary focus of NESC rules is to ensure the safety of individuals during the operation and maintenance of electric supply and communication lines. This includes establishing guidelines that mitigate risks associated with working near electric infrastructure, thereby protecting workers, the public, and property from potential hazards. The NESC outlines requirements for safe work practices, proper equipment usage, and maintenance protocols, which are crucial in preventing electrical accidents and injuries.

In contrast, while crane performance optimization, environmental protection, and load testing procedures are important aspects of overall safety and operational efficiency, they do not represent the central emphasis of NESC regulations. Instead, those guidelines are more associated with ensuring that personnel remain safe around electrical systems, which is why safeguarding persons is the correct and primary focus of the NESC rules.
