Your Guide to the 2026 NEC: Navigating Upcoming Electrical Code Changes
Published on April 16, 2026 by Staff Writer | Edited by Nate Bortz
The National Electrical Code (NEC) is updated every three years. This keeps it current with electrical technology trends, new products, and updated safety protocols.
Updates are also used to encourage the development of safer products and to help designers better manage (and sometimes lower) construction costs. There are many changes in this edition, some small and some major.
This article looks at some of the major changes, covers the state-by-state adoption maze, and touches on where you can get training for the latest version.
An updated code doesn’t mean the state you work in will require immediate compliance. States typically adopt updates very gradually.
2026 vs. 2023: Selected Changes
The latest 2026 version is meant to replace the 2023 edition. It also incorporates changes that pave the way for the 2029 edition, which will majorly overhaul the way the electrical code is organized.
It also includes 13 new articles, some of which we’ll discuss here. These cover recent and emerging topics like:
- Energy Management Systems (EMS)
- Power Control Systems (PCS)
- The use of medium-voltage and low-voltage communication systems
Structural Updates
The 2023 edition is organized into nine chapters, while the 2026 version keeps these chapters but moves some information between them.
Now, definitions are grouped together rather than spread throughout the document.
The National Fire Protection Association (NFPA) implemented this restructuring to make the code easier to read and use, especially for online users. It also lays the groundwork for a move to 23 chapters in 2029.
However, when looking at the new edition, you may find that information is now in a different place compared to where you found it before.
Revised load calculations to support EMS
Previous editions required the calculation of the maximum current that might be drawn in an area.
The 2026 changes recognize that the growing use of EMS permits software-controlled current limits. This may allow downsizing of electrical inputs as peak demand will be lower.
More details covering photovoltaic (PV) systems
Methods for calculating loads, regardless of system size, are expanded and clarified. This provides more flexibility for residential and small commercial options, but also means more documentation will be needed.
Other changes relate to rules on disconnects and grounding. There will be more standardization of disconnect methods and clearer labeling and signage. A new approach to sizing grounding conductors may make them larger and more expensive.
Increased detail on microgrids
Previously covered in multiple code articles that left many issues unclear, these small-scale generation and storage systems are now addressed more explicitly.
The growing role and recognition of EMS, now covered in Chapter One, means systems can be designed using dynamic load control.
Updates also address systems with multiple parallel sources, like PV plus Energy Storage Systems (ESS) operating with a generator and overcurrent protection when a power source connects inside a building.
- PCS now requires controls to prevent overloads, and requirements regarding disconnects are clarified.
- Covering an issue of growing importance, the code now has specific notes regarding the implementation of bidirectional flow control (as when powering a house from an EV).
- There’s also a clearer distinction between new technology ESS and traditional batteries, and notes on battery capacity sizing for optional standby systems.
- For larger-scale microgrids, the code elaborates on the requirements for medium-voltage (>1,000 V ac, >1,500 V dc) systems. This supports establishing larger-scale generation and ESS.
Changes to EV charging installations
The 2026 edition extends coverage beyond pure EVs to other electrically powered vehicles, from boats to golf carts and scissor lifts.
- Emergency shutoffs will now be required on EV chargers in public and commercial locations.
- To address larger charger installations, the code has changes designed to support implementing medium voltage systems.
- The increased role of EMS will support higher charger installation density.
New articles on limited energy systems
“Limited energy,” meaning less than 100V, refers to components used for communication within a building and its entrance. This includes Power-over-Ethernet (PoE) technology as well as devices like video doorbells.
By addressing PoE, the updated code covers situations like PoE lighting now being installed in many commercial buildings. Again, this can also be linked to EMS for activities like load shedding.
Installing communication wiring alongside power circuits, which can be an issue in industrial automation and factory-built solutions, is also further clarified.

Navigating State-by-State Adoption
Every state follows a version of the national code, but the time taken to adopt an updated edition can vary widely. And to complicate matters, in some states, individual municipalities decide which edition they will follow.
In most states, the process for adoption is handled by an administrative agency. When a new edition is published, this agency starts a review process.
Electrical advisory boards or other stakeholders will review what has changed and may make modifications to suit local needs. Local climate and existing electrical infrastructure are often reasons for alterations.
After deliberation, the modified code is published for review and then officially adopted.
Keep Your Electrical Knowledge Compliant with JADE Learning
Even if your state has not yet officially adopted the 2026 NEC, many jurisdictions will eventually move in that direction. For example, Massachusetts is expected to approve the code soon, while other states such as Colorado, Pennsylvania, North Carolina, and Kansas will follow as their review processes progress.
Getting familiar with the changes now can give you a competitive advantage by helping you stay ahead of industry shifts, avoid last-minute compliance challenges, and confidently adapt when the new code takes effect.
To support this transition, we are actively releasing new continuing education (CE) courses that cover the latest updates and evolving state requirements.
