NFPA 70®, National Electrical Code® (NEC®), is the authoritative document addressing electrical installations in residential, commercial, and industrial settings. The NEC is revised every three years to stay in sync with industry practices, emerging trends, and the development and introduction of technologies to provide comprehensive rules for designers, installers, inspectors, engineers, electricians, and anyone else who works in the electrical industry. The code is organized for ease of use.
Proposed changes in the 2026 NEC include new, expanded, and revised content and provisions, including:
- Addition of new articles in Chapter 2, including the separation of code articles addressing 1000 Volts ac and 1500 Volts dc.
- Reorganization of articles and sections for a more user-friendly flow and better ease of use.
- Removal of redundancies and correlation of terms used across the NEC for clarity and useability.
- Removal of the stand-alone status of Chapter 8, allowing Chapters 1 through 4 to apply generally to Chapter 8.
- Adjustment of demand factors and loads due to increased energy efficiencies.
- Addition of new Article 750, “Grounding and Bonding of Limited Energy Systems.”
- Addition of new Informative Annex L, “Proposed Organization of the 2029 National Electrical Code,” to prepare for probable changes in the next edition.
Stay up to date as you design, install, and inspect with the most current electrical requirements with the latest NEC.
