What is covered in Article 200 of the NEC?

Article 200 of the National Electrical Code (NEC) focuses specifically on the use and identification of grounded conductors. This article provides guidelines for the proper color coding, labeling, and general handling of grounded conductors, which are crucial for ensuring safety in electrical systems. Grounded conductors, which are typically neutral wires, play a vital role in the functioning of electrical circuits and their correct handling can prevent hazardous conditions such as electrical shock and equipment failure.

Understanding the specifics of this article is essential for electrical contractors and professionals, as it aligns with the overall objective of maintaining safe electrical installations and operations. It emphasizes the importance of recognizing and identifying these conductors in various applications to ensure compliance with safety standards.

While power distribution systems, electrical safety procedures, and maintenance of electrical equipment are critical aspects of electrical work, they are not the primary focus of Article 200. Each of these topics is addressed in different articles throughout the NEC, but Article 200 specifically delineates the requirements for grounded conductors, making option B the correct choice.
