As an electrician, inspector, engineer or contractor it is imperative that you stay informed about these changes if you wish to remain in compliance. In this article we will highlight some of the most significant differences between NFPA 70 2023 and NFPA 70 2026 as well as some of the most major code updates, and ultimately assist you with determining which edition of the code you should be using. When comparing NFPA 70 2023 vs NFPA 70 2026, the 2026 edition places stronger emphasis on modern electrical systems and safety clarity. Many professionals upgrading from NFPA 70 2023 vs NFPA 70 2026 prefer the newer edition for long-term compliance.
Big Changes from NFPA 70:2023 to NFPA 70:2026
1️⃣ More & Better EV Charging Guidelines
The 2026 NEC defines rules for EV Charging Systems in greater detail than they were defined in the 2023 Edition. The 2023 Edition did contain some provisions for EV Charging, but the 2026 Edition strengthens the installation, grounding, and safety standards for the rapid expansion of the EV Infrastructure.
2️⃣ Better AFCI & GFCI Protections
The 2026 NEC clarifies the requirements for AFCI & GFCI Protection, thereby reducing confusion for both Residential & Commercial installations. This means fewer Electric Shock and Electrical Fire Hazards, compared to the NFPA 70:2023.
3️⃣ Update for Energy Storage Systems
NFPA 70:2023 provides limited coverage for Energy Storage Systems. The 2026 Edition greatly enhances the definitions, installation, and safety information for Energy Storage Systems (Batteries) including those installed in Residential and Commercial Applications.
4️⃣ Clarified Outdoor Disconnect/Emergency Shutdown Requirements
The 2026 NEC provides clarity with respect to Outdoor Disconnects and Emergency Shutdowns; thus, compliance with these requirements will be easier for Installers & Inspectors when compared to the previous Edition.
5️⃣ Better Organization & Reduced Misinterpretation
NFPA 70:2026 greatly improves the Organization and Language used in the NEC making it much less likely that a person will misinterpret the requirements when compared to the 2023 Code Cycle.
Which Code Should You Use?
Although some jurisdictions may still accept NFPA 70:2023, the NFPA 70:2026 Edition would be the recommended Code for:
New Installations;
New EV Charging Projects;
Commercial & Industrial Work;
Preparing for the Exam; and
Long-Term Compliance.
When using a code, always make sure to use the most current Edition.
