What is covered under NEC Article 250?

NEC Article 250 specifically addresses the grounding and bonding requirements for electrical systems. Grounding is essential for safety as it helps to prevent electrical shock and ensures the proper functioning of electrical equipment. This article outlines not only how grounding systems should be installed but also the materials that can be used, the methods of bonding various components to maintain electrical safety, and the criteria for grounding electrode systems. Understanding these guidelines is crucial for ensuring the electrical installation is safe and complies with national standards.

While the other choices pertain to important aspects of electrical systems, they are not the focus of Article 250. Wiring methods, lighting standards, and installation maintenance guidelines are covered under different articles within the NEC. Article 250's emphasis on grounding and bonding is vital because it directly impacts the safety and effectiveness of an electrical system.
