National Electrical Code Handbook HB 2020

Based on the 2020 NEC, the new NEC Handbook reflects industry trends and code changes addressing electrical technologies that are transforming the field. You get detailed explanations on how to implement requirements along with the reasoning behind major changes that could affect your designs and installations.

The NEC Handbook provides a narrative interpretation featuring expert commentary and informative exhibits that help you increase code comprehension and explain NEC requirements to clients and others who might not have professional electrical training.

The NEC Handbook is designed explicitly for electrical professionals. The complete NFPA 70, NEC, the index is also included for easy reference to the code information you require. The handbook’s commentary text is colored blue to differentiate it from the code text.
