According to Italian Law No. 186 of March 1, 1968, all electrical installations must comply with CEI standards. Non-compliance voids insurance policies, leads to administrative fines, and creates criminal liability in case of accidents (e.g., electrocution or fire).

Some professionals ask: "Can I keep using the 2021 version until 2025?" The answer depends on your project:

| Scenario | Required edition | |----------|------------------| | New building permit filed after June 2024 | 2024 edition | | Maintenance on existing installation (no design change) | Previous edition (2021) is acceptable | | EV charger installation in a condo | 2024 edition (due to revised Section 722) | | Photovoltaic + storage system | 2024 edition (new DC protection rules) | | Legal compliance for a rental property (Law 46/90 & DM 37/08) | Latest edition in force at time of installation |

Courts and insurance companies increasingly refer to the latest edition to determine "state of the art" in case of electrical fires or electrocution. Using an outdated standard could be considered negligence.

If you are upgrading from a previous version (e.g., 2021 or 2022), the 2024 PDF includes the following critical updates:

New annexes address smart home installations, including requirements for data cabling alongside power lines and the electromagnetic compatibility (EMC) of power line communication (PLC) systems.

The Norma CEI 64-8 (8th Edition) is non-negotiable for anyone working with electricity in Italy. It is a masterpiece of engineering standardization that balances safety with technical feasibility.

Recommendation: Do not rely on pirated or outdated versions from 2016. The electrical landscape has changed too much (EVs, PVs). If you are a professional, invest in the official 2024 PDF package from the CEI store to ensure you have the correct data for your certifications. Norma Cei 64-8 Pdf 2024

The Italian regulatory landscape for electrical installations has undergone a significant transformation with the publication of the Norma CEI 64-8 PDF 2024 (IX Edition). This new edition, published in July 2024 and officially in force since November 1, 2024, replaces the previous 2021 edition to align with European harmonization documents (CENELEC) and address modern technological shifts like electric vehicle charging and prosumer energy management. Overview of the CEI 64-8 2024 (IX Edition)

The CEI 64-8 standard remains the fundamental reference for the design, installation, and testing of low-voltage electrical systems (up to 1000V AC or 1500V DC) in Italy. Compliance with this standard is a legal requirement under Law 186/68 and DM 37/08 to ensure "workmanlike" (a regola d'arte) safety standards. Key Changes in the 2024 Edition

The IX Edition is not just a minor update; it consolidates previous variants and introduces structural rewrites to several core chapters:

Chapter 41: Protection Against Electric ShockThe section on protection against direct and indirect contacts has been completely restructured. It now emphasizes the concepts of Basic Protection and Fault Protection, with updated requirements for earthing resistance in TT systems.

Chapter 46: Isolation and SwitchingThis chapter was entirely replaced and revised to better align with international standards, clarifying requirements for control devices and safe isolation.

Chapter 52: Wiring Systems and CPR ComplianceUpdated to reflect the Construction Products Regulation (CPR) regarding cable fire performance, integrating safety requirements for cable selection and installation.

Part 8: Energy Efficiency and ProsumersPreviously divided into Parts 8-1 and 8-2, these have now been merged into a single Part 8. This section covers the design of "Prosumer" installations—users who both produce and consume energy—optimizing local production and storage. If you have obtained the official PDF, here

Section 722: Electric Vehicle Power SupplyProtections against overvoltages are now mandatory for public charging points, and new prescriptions have been introduced for wireless charging systems.

Section 713: Furniture with Electrical PartsThis new section replaces the old CEI 64-11 standard, defining specific safety characteristics for electrical components integrated into furniture. Accessing the Norma CEI 64-8 PDF 2024
