The standard remains organized into eight core parts, now updated to align with European and international documents (HD 60364): Part 1: Object, scope, and fundamental principles. Part 2: Definitions. Part 3: General characteristics.

Part 4: Safety requirements (protection against shock, thermal effects, and overcurrent). Part 5: Selection and installation of electrical equipment.

Part 6: Verification (initial and periodic inspections and testing).

Part 7: Special installations or locations (e.g., medical rooms, construction sites).

Part 8: Energy efficiency and Prosumer (active user) installations. Key Technical Updates in the 2024 Edition CEI 64-8/4

The ninth edition of the Norma CEI 64-8 was published in July 2024 and officially entered into force on November 1, 2024. This new edition replaces the previous 2021 version (the 8th edition) as the primary regulatory reference for low-voltage electrical installations in Italy.

CEI 64-8/8:2024 Low-voltage electrical installations - Part 8

What is Norma CEI 64-8?

The CEI 64-8 is the Italian national implementation of the international IEC 60364 series (Low-voltage electrical installations). It is published by the Comitato Elettrotecnico Italiano (CEI), the Italian Electrotechnical Committee. The standard dictates:

  • General principles of electrical installation design.
  • Selection and erection of electrical equipment.
  • Verification and testing procedures.
  • Requirements for special installations or locations (e.g., bathrooms, construction sites, photovoltaic systems).

Compliance with CEI 64-8 is not merely a best practice; in many cases, it is mandatory under Italian law (specifically, the DM 37/08 and the Consolidated Law on Safety at Work - Legislative Decree 81/08).

The 2024 Edition: What’s New?

The 2024 edition (officially titled CEI 64-8: 2024-XX) is not a radical rewrite but an evolution. Following the typical CEI update cycle, the 2024 version incorporates: What is Norma CEI 64-8

Conclusion

The Norma CEI 64-8 PDF 2024 represents the latest evolution of electrical safety and technical best practice in Italy. Whether you are designing a residential complex, an industrial plant, or a public EV charging hub, the 2024 edition provides the mandatory rules for protection, verification, and energy efficiency.

Do not rely on outdated copies or illegal downloads. Purchase the official PDF from the CEI Store, study its changes (especially sections 722 and the new AFDD requirements), and ensure every electrical installation you certify meets the 2024 standard.

For further reading, pair CEI 64-8 with:

  • CEI 0-16 (for HV/LV substations).
  • CEI 11-27 (work safety on electrical installations).
  • IEC 60364-4-41 (direct contact protection – identical to CEI 64-8 Part 4).

Stay safe, stay updated, and always refer to the official source.

Content and Structure

The document is massive, typically spanning several parts (Part 1 to Part 6), totaling over 800 pages. It covers every aspect of an electrical system's lifecycle:

  1. Part 1 (General): Scope, object, and fundamental principles.
  2. Part 3 (Assessment of General Characteristics): Crucial for designers to understand the environment (external influences, compatibility).
  3. Part 4 (Protection for Safety): The core of the standard. It details protection against electric shock (direct and indirect contact), thermal effects, and overcurrent.
  4. Part 5 (Selection and Erection of Equipment): Practical rules on wiring systems, switchgear, and grounding.
  5. Part 6 (Verification): The protocols for testing and certifying systems.
