Which part of the NEC deals with hazardous locations?

The National Electrical Code (NEC) has specific sections that address various aspects of electrical installations, including those in hazardous locations. Article 500 is dedicated to the classification of hazardous locations due to the presence of flammable gases, vapors, liquids, or combustible dust. This article outlines the requirements for electrical equipment and installations in these areas to ensure safety and minimize the risk of explosions or fires.

This focus on hazardous locations is essential because it helps electrical professionals understand how to select appropriate equipment, implement safety measures, and comply with regulations designed to protect both people and property in environments where hazardous materials are present. Understanding the provisions of Article 500 is crucial for anyone working with electrical systems in such contexts to ensure proper installation and maintenance practices.

The other articles mentioned, such as Article 200, primarily focus on general requirements related to the administration and measurement of electrical systems, Article 300 deals with general wiring methods and materials, and Article 400 covers flexible cords and cables, which do not specifically address the unique challenges posed by hazardous environments.
