NEC Articles List: A Complete Guide to the 2026 National Electrical Code

This NEC articles list shows how the 2026 National Electrical Code (NFPA 70) is organized, what each major article covers, and where to look first for a given job. Whether you are an electrician, a student preparing for an exam, or a homeowner trying to read a permit, this NEC articles list gives you the article number before you open the code book.

The NEC is revised every three years, and the 2026 edition moved several articles around. Older lists online can point you to the wrong number. Below you will find the chapter-by-chapter NEC articles list, a quick-reference chart of the most-used articles, a plain-English summary of what changed in 2026, and links to our deeper guides on each topic.

Quick answer: The NEC has nine chapters. Chapters 1 to 4 hold the general rules, Chapters 5 to 7 cover special occupancies, equipment and conditions, Chapter 8 covers communications systems, and Chapter 9 holds the tables. The most-used articles are 110, 210, 230, 240, 250, 310 and 314.

What Is the NEC Articles List?

The National Electrical Code is the US standard for safe electrical installation. The National Fire Protection Association (NFPA) publishes it as NFPA 70. The code is divided into chapters, then articles, then parts, then sections. An NEC articles list is the table of contents of that structure: each article has a number and a title, such as Article 210 Branch Circuits or Article 250 Grounding and Bonding.

Knowing the list matters because almost every code question starts with “which article covers this?” Once you have the article, the section follows quickly. For example, dwelling-unit GFCI rules sit in 210.8(A), which we cover in our guide to NEC Article 210.8 A.

What Changed in the 2026 NEC Articles List

The 2026 edition is the biggest reshuffle in years. These are the changes that affect any NEC articles list you saved from an older edition:

• Load calculations moved. Branch-circuit, feeder and service load calculations moved from Article 220 to a new Article 120 in Chapter 1.
• Energy management systems moved. Article 750 content now lives in Article 130.
• Article 235 was deleted. Its over-1,000 V content was split into Articles 265 to 268, with Article 270 covering grounding and bonding for those systems.
• Chapter 8 lost its independence. Section 90.3 now applies Chapters 1 through 7 to communications systems, and Articles 770, 805 and 840 were deleted.
• New Article 206. It covers non-power-limited remote-control and signaling circuits.

Always confirm which edition your local authority enforces before you cite an article number in a design or inspection.

NEC Code Questions and Answers

Reading the code is one skill. Applying it under exam pressure is another. Our upcoming guide to NEC code questions and answers collects practice questions on definitions, grounding, branch circuits, load calculations and wiring methods, each with the article and section that gives the answer. It pairs well with this NEC articles list because the article number is the first thing every exam question tests.

What Article Can You Find NEC Definitions

Article 100 holds the definitions, and Article 90 explains how to use them. Terms such as “qualified person,” “branch circuit,” “feeder” and “service” are defined there, and the rest of the code assumes you know them. Some articles also carry their own definitions in Section XXX.2. Our upcoming guide on what article you can find NEC definitions walks through both places and the most-searched terms.

NEC Code Year by State

The NEC does not apply by itself. States, counties and cities adopt an edition by law, often with amendments, so one state can enforce the 2020 NEC while its neighbor enforces the 2023 or 2026. Our upcoming NEC code year by state guide will show the adopted edition by state, plus notes for New York City, New Jersey and North Carolina. Check it before you pick an edition from any NEC articles list.

NEC Articles List PDF and Free Download

People search for an NEC articles list PDF, an NEC articles list free download, the National Electrical Code 2026 PDF and an NEC 2026 PDF free download. Here is the honest answer.

Is There a Free NEC 2026 PDF?

The full NEC is copyrighted by NFPA, so there is no legal free PDF of the complete code. NFPA does offer free read-only online access to NFPA 70 on nfpa.org after you register, and it sells print and PDF copies. Unofficial PDFs on random sites are often out of date, incomplete or pirated, so they can send you to the wrong edition.

For a free NEC articles list PDF alternative, save or print the chapter chart and quick-reference chart on this page. They give you the article numbers you need, and you can then read the exact wording in the official online copy.

NEC Articles List 2020, 2021 and 2023 vs 2026

The NEC is published every three years: 2017, 2020, 2023 and 2026. There is no 2021 edition, so a search for the NEC articles list 2021 usually means the 2020 edition, which was current that year. Most article numbers stay the same from edition to edition. What changes is section numbering and the few articles that were reorganized, such as load calculations (Article 220 in 2020 and 2023, Article 120 in 2026).

When you work on an older project, use the edition your jurisdiction adopted and note it in your design documents.

NFPA 70 and the NEC: What NFPA Does

Searches for “NFPA NEC” and “NFPA 70, National Electrical Code (NEC) 2026” point to the same document. NFPA 70 is the standard’s number, and the National Electrical Code is its title. NFPA is a nonprofit that develops the code through code-making panels, public input and public comment. It does not enforce the NEC.

Do not confuse NFPA 70 with NFPA 70E. The 70E standard covers electrical safety in the workplace. See phase to phase clearance per NEC and NFPA 70E for one place where they meet.

NEC Code Chapters Explained

The NEC code chapters work in layers. Chapters 1 to 4 apply to every installation. Chapters 5, 6 and 7 add to or change those general rules for special occupancies, equipment and conditions. Chapter 8, for communications systems, was independent until the 2026 edition integrated it with the rest of the code. Chapter 9 supplies tables you use alongside the other chapters.

In practice, start in Chapters 1 to 4. Then check whether a special occupancy or special equipment article modifies the rule. For example, a swimming pool job starts with Article 680 but still relies on Articles 110, 210 and 250.

NEC for Dummies: How to Read the NEC Code Book

The code book is written in legal language, so beginners often search for an NEC for dummies or NEC code book for dummies guide. This five-step routine makes it manageable:

1. Read Articles 90 and 100 first. They explain the code’s scope and define its terms.
2. Find the article. Use this NEC articles list or the index in the code book.
3. Read Part I of the article. It holds the general requirements.
4. Check Chapters 5 to 7. A special article may change the general rule.
5. Confirm local amendments. Then use Chapter 9 tables and Annex C where needed.

Section numbers follow a pattern. In 210.8(A)(1), 210 is the article, 8 is the section, (A) is the subsection and (1) is the list item.

NEC Article 200 PDF

Article 200 covers the use and identification of grounded conductors, including the white and gray finish rules. There is no separate free PDF of the article. Read it in NFPA’s free online access, and see our guides on neutral to ground voltage and Article 250 for the related grounding rules.

NEC Article 504 PDF

Article 504 covers intrinsically safe systems, which limit electrical energy so that equipment cannot ignite a hazardous atmosphere. It sits in Chapter 5 with the other hazardous location articles and is used mostly in process plants. The official text is available through NFPA’s free online access.

NEC Style Manual PDF

The NEC Style Manual is an NFPA document about how code text is written and formatted. It is aimed at code-panel members and people who submit proposed changes, not at installers. You do not need it to apply the code.
