NEC 2026 for Engineers and Electricians

It is a free-to-learn online course on the 2026 National Electrical Code (NFPA 70) for people who design, install or inspect electrical systems. It covers code navigation, Article 110, the new Article 120 load calculations, conductor and OCPD sizing, grounding and bonding, wiring methods, motors, transformers, hazardous locations, and PV, energy storage and EV charging, with worked problems in every module.

The biggest change is that load calculations moved from Article 220 to a new Article 120, where the dwelling general lighting load dropped from 3 to 2 VA per square foot while branch circuits are still counted at 3 VA. Energy management systems moved to Article 130, systems over 1,000 V ac moved to Articles 265 to 270, control circuits moved to Article 206, Chapter 8 lost its independence, and GFCI, arc-flash labelling and service disconnect rules were revised.

It is for electrical engineers, designers, electricians and apprentices, inspectors and estimators who work to the NEC or are moving to NEC projects. You need basic circuit theory, including single-phase and three-phase power, and a calculator; no previous code study is needed.

Yes, every module, the notes, worked problems, practice tasks, the project and the final assessment are free to learn. It takes about 22 hours at your own pace, including about 13.6 hours of video, and the optional project takes about 12 hours more.

No. NFPA lets anyone read NFPA 70 (2026) free in a read-only online viewer after a free registration, and the course notes explain each rule in their own words with worked numbers. A printed or licensed copy is useful on the job but optional for the course.

It covers much of the NEC knowledge those exams test, including finding rules fast, load calculations, conductor and OCPD sizing, grounding and motors, so it is useful preparation. It is not tied to any state's exam, it gives no continuing-education credit, and electrician licensing is set by each state or country.

You get a verifiable certificate of completion when you finish the modules and pass the 15-question final at 60 percent. It carries a unique certificate number and a QR code that open a public verification page showing the course, the modules covered and your final score. It is not an NFPA credential or an electrician licence, and EDWartens is not affiliated with NFPA.

Yes. Most of the world wires to IEC 60364 (BS 7671 in the UK), which our Wiring Regulations course covers, but the Philippine Electrical Code Part 1 is based on the NEC, Mexico's NOM-001-SEDE follows its structure, and US-specified oil and gas, data centre and pharmaceutical projects, including many in the Gulf, name NFPA 70 in their specifications.

Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹599 including GST for this intermediate course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
