What is the primary focus of Article 250 in the National Electrical Code?

Article 250 of the National Electrical Code (NEC) primarily focuses on grounding and bonding, which are critical aspects of electrical safety. Grounding provides a path for electrical current to safely dissipate into the earth or ground, reducing the risk of electric shock and protecting equipment from transient voltages. Bonding, on the other hand, involves connecting various metal parts of an electrical system to ensure they maintain the same electrical potential, thereby preventing dangerous voltage differences that could lead to shock hazards.

This article outlines the requirements for grounding electrode systems, ground conductors, and the bonding of equipment and systems to ensure effective grounding and bonding practices. It addresses the methods and materials used, as well as the necessary configurations to achieve safety in electrical installations.

By focusing on these critical safety components, Article 250 helps minimize electrical hazards and enhance the overall reliability of electrical systems, making it essential for electricians and engineers in designing and implementing safe electrical installations.
