Article 100 & 110

Article 100 of the National Electrical Code (NEC) serves as its dictionary, defining essential terms used throughout the code. This ensures consistent understanding and application of electrical terminology.

Article 110 establishes fundamental guidelines for electrical installations. It covers critical aspects like equipment approval, proper installation practices, and safety considerations. This article lays the groundwork for the more specific requirements found in subsequent sections of the NEC. Together, Articles 100 and 110 provide a strong foundation for safe and compliant electrical systems.
