What does the final chapter of the NEC cover?

The final chapter of the National Electrical Code (NEC) is designed to provide additional information and guidance that extends beyond the core regulatory framework. By covering informative annexes A through K, it serves as a comprehensive resource that contains valuable information such as calculations, examples, and supplementary data related to the NEC. These annexes are not part of the enforceable code but are intended to assist code users in understanding and applying the requirements of the NEC effectively.

This addition of informative content helps electricians, inspectors, and other stakeholders in the electrical industry by providing insights and clarity on various topics, thereby enhancing safety and compliance in electrical installations. Overall, the final chapter acts as a significant reference tool, enriching users' knowledge and application of the NEC.
