Introduction to NEC Article 100

The National Electrical Code (NEC) serves as a critical guideline for electrical installations in the United States. Article 100 plays a significant role in shaping our understanding of essential definitions within the NEC. This article outlines various terms that are vital for both compliance and safety in electrical work.

The Meaning of ‘Approved’

One key term in NEC Article 100 is ‘approved.’ The definition provided indicates that something is considered approved if it is acceptable to the authority having jurisdiction (AHJ). This means that any installation or material must not only adhere to the NEC but also receive a stamp of approval from the local authorities responsible for enforcing the code.

Importance of Understanding ‘Approved’

Understanding what qualifies as ‘approved’ is crucial for electricians and contractors. It ensures that the work meets local reliability standards and builds trust with clients. The authority having jurisdiction may look at various factors, such as compliance with safety standards and past performance of the materials or systems being used. Therefore, it is essential for professionals in the electrical field to stay informed about these definitions in NEC Article 100 to ensure their work meets all regulatory expectations.
