Which principle does NEC Article 110 emphasize regarding electrical installation?

NEC Article 110 emphasizes the principle of ensuring safety for both installation and usage. This focus on safety is foundational to the National Electrical Code, which aims to protect people and property from electrical hazards. It lays out requirements such as properly identifying equipment for safe use, ensuring adequate space around installations for maintenance and accessibility, employing suitable materials, and following specific procedures during installation to mitigate risks of electrical shock, fire, or equipment failure. The overarching goal is to create safe conditions for workers performing installations and the end-users of the electrical systems. This commitment to safety is a critical component of any electrical installation and is essential for compliance with the code.

In contrast, while concepts like energy efficiency, advanced technology, and sustainability are important in modern electrical practices, they do not capture the primary focus of Article 110, which is fundamentally centered on safety.
