The National Fire Protection Association (NFPA) and Mike Holt Enterprises announced their collaboration in publishing a book that explains the key changes in the next edition of NFPA 70, National Electrical Code (NEC⁾. The book, titled Changes to the National Electrical Code, 2026 edition, is the latest project following their collaboration on the publication of the 2023 NEC changes book. This new book will feature full color illustrations and photos, insightful commentary, technical clarifications, and a general review of the code. Electrical professionals, including electricians, electrical contractors, engineers, and inspectors, will find it a valuable resource for understanding the NEC.

"This book will absolutely be the best resource for understanding the changes in the revised 2026 edition of the NEC. It's the only NEC changes book officially recognized by NFPA," said Jim Pauley, NFPA president and CEO. "We are excited to partner with Mike Holt Enterprises once again to advance NFPA’s safety mission and bring this information to professionals responsible for understanding and applying NEC requirements."

The NEC is the most widely used code in the United States and is used extensively across the globe to safeguard people and property from electrical hazards. To incorporate the latest technologies, research, and learnings, the NEC is updated every three years.

"The NEC remains the essential resource for everyone who works in the electrical industry," said Mike Holt, president of Mike Holt Enterprises. "We are thrilled to be partnering once again with NFPA to meet today’s electrical safety challenges and to help electrical professionals understand the changes in the 2026 edition. It is an honor to develop products based on the NEC that help individuals understand and apply the code easily to their work. The new edition will include hundreds of detailed graphics and photos, and in-depth analysis on the changes."

Holt has devoted his career to studying and understanding the National Electrical Code and has published his Illustrated Guide to Changes to the NEC for over 40 years.

The Changes to the National Electrical Code, 2026 edition book will be available in Fall 2025 through NFPA and Mike Holt Enterprises. The 2023 edition, Changes to the National Electrical Code, is currently available to purchase on the NFPA website and Mike Holt Enterprises website.
