What is the nature of the notes included in the NEC?

The notes included in the National Electrical Code (NEC) serve as explanatory and non-enforceable content, which provides context, clarification, and further information about the code provisions. These notes help users to better understand the intent and application of the code, aiding in the proper interpretation and implementation of electrical standards.

While some parts of the NEC outline strict regulations and enforceable requirements, the notes primarily focus on enhancing comprehension rather than imposing obligations. They offer insights into best practices, but they do not constitute mandatory rules that must be followed. Instead, they serve as an educational resource for electricians, engineers, and other professionals engaged with electrical installations and safety. This function is distinct from more prescriptive parts of the NEC that dictate specific requirements for compliance.
