What is the primary purpose of an informational note in the National Electrical Code?

The primary purpose of an informational note in the National Electrical Code (NEC) is to provide additional information related to a specific rule in the NEC. These notes are intended to enhance the understanding of the code requirements by offering context, explanations, or supplementary details that help in the interpretation and application of the rules. While these notes do not carry the weight of enforceable code requirements, they serve as valuable resources for those interpreting or implementing the code, making it clearer how to comply with the standards set forth in the NEC.

Informational notes help clarify technical language or provide insights that may not be immediately obvious from the text of the rules themselves, thus supporting practitioners in adhering to safe electrical practices without altering the binding nature of the code requirements. This vital aspect of the NEC promotes better understanding and implementation of electrical safety measures, ensuring all parties are well-informed about the code's intent.
