What are the Informational Notes (I-Notes) in the National Electrical Code®?

Informational Notes, commonly referred to as I-Notes, in the National Electrical Code® provide explanatory information that is intended to clarify or elaborate on the requirements set forth in the code. These notes serve as helpful guidance for understanding the rationale behind specific requirements, but they do not impose mandatory obligations. Their purpose is to enhance comprehension and aid in the proper application of the code without being enforceable or essential for compliance. This distinction is important, as compliance with the National Electrical Code® focuses on meeting the mandated requirements, while I-Notes are supplementary and utilized for educational purposes. Thus, their role lies in providing context and insight rather than establishing regulatory standards.
