2026 National Electrical Code - Spiral Bound

Available October 2025

Stay ahead of electrical safety and compliance with the 2026 edition of NFPA 70® National Electrical Code® (NEC®)—the most trusted and up-to-date standard for electrical installations worldwide. Revised every three years to address emerging technologies, industry advancements, and evolving hazards, the NEC ensures safe and reliable electrical systems in residential, commercial, and industrial settings. The 2026 edition introduces critical updates that enhance usability, clarity, and safety, including new voltage-specific articles that separate requirements for systems over 1000V AC and 1500V DC for improved precision; a streamlined organization with renumbered sections and reduced redundancies for easier navigation; and the integration of Chapter 8 (Communications Systems) with Chapters 1–4 to ensure consistent application of general rules. A new Article 750 addresses grounding and bonding for limited-energy systems, while updated demand factors reflect modern energy-efficient loads. Additionally, Informative Annex L provides a preview of the proposed structure for the 2029 NEC. Designed for electricians, engineers, inspectors, designers, and contractors, the 2026 NEC delivers comprehensive coverage across key areas such as wiring and protection (including branch circuits, feeders, grounding, and overcurrent protection); wiring methods and materials (conduits, cables, and raceways); equipment for general use (motors, transformers, HVAC systems, and batteries); hazardous locations (Class I, II, III, and zone-based classifications); renewable energy systems (solar PV, wind, fuel cells, and energy storage); as well as emergency and standby power systems. It also includes essential updates for emerging technologies, such as EV charging infrastructure, data centers, and cannabis oil equipment.
