Description
NFPA 70, National Electrical Code, 2023 edition (with tabs)
This is the code book itself, the 2023 revision of NFPA 70, without commentary. It is the document that installations are inspected against, covering residential, commercial and industrial work.
The 2023 edition was reorganised for easier navigation. The clearest change is a much larger Article 100, which now gathers the defined terms into one place instead of scattering them through the book. Anyone who has lost ten minutes chasing a definition will appreciate it.
This listing is the 2023 edition. NFPA now lists a 2026 edition of NFPA 70, so check which year your jurisdiction, contract or exam cites before you order.
What the 2023 revision changes
- Expanded Article 100 holding the consolidated definitions.
- Revised requirements for wiring methods, overcurrent protection, grounding and bonding, and electrical equipment.
- Coverage of emerging technologies and higher voltage systems.
- A reorganised layout aimed at faster lookup.
Tabbed for coursework and exams
The tabbed format is the practical reason to buy this version. During a lab, an open book exam or a plan review, finding the article is half the work.
Who it is for
Electrical students, apprentices and instructors, plus anyone working toward design, installation, inspection or code compliance roles. It is a standard text in electrical and building services programmes.
