CEI 64-8/8:2024 Low-voltage electrical installations - Part 8 7 Jan 2024 —

If you need a full paper draft, let me know and I can expand it.

Why it’s interesting

The ninth edition of the Norma CEI 64-8, often referred to as the "Bible" of electrical installations in Italy, was officially published in July 2024 and entered into force on November 1, 2024. This update is critical for designers and installers, as it aligns Italian regulations with European (CENELEC) and international (IEC) standards. Overview of the Ninth Edition (2024)

The CEI 64-8:2024 regulates low-voltage electrical systems (up to

DC). It applies to all new installations, as well as significant expansions or transformations of existing systems. Compliance with this standard is the primary way for professionals to satisfy the "state of the art" requirements mandated by Italian Law 186/68 and DM 37/08. Key Updates and Changes

The 2024 edition introduces several structural and technical shifts:

Restructured Part 4 (Safety): Chapter 41, focusing on protection against direct and indirect contacts, has been completely rewritten and renumbered to improve clarity.

Expansion of RCD Requirements: For residential systems, the requirement for

residual current devices (RCDs) has been extended beyond socket circuits to include light circuits.

Protection Against Thermal Effects: Chapter 42 now includes tighter alignment with the EU Construction Products Regulation (CPR), specifically regarding the fire performance and reaction of electrical cables. Why it’s interesting

Consolidated Part 8 (Energy Efficiency): Previously split, the 2024 edition merges Part 8-1 and Part 8-2 into a single section, covering energy efficiency and "Prosumer" low-voltage electrical installations (PEI).

Isolation and Control: Chapter 46 has been entirely revised to streamline prescriptions for safety isolation and emergency switching.

Inverter-Based Systems: New guidelines address TN systems downstream of inverters, specifying that fault voltages must be reduced to safe levels (

DC) since traditional circuit breaker coordination may not apply. How to Access the Norma CEI 64-8 PDF

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

The Norma CEI 64-8 Nona Edizione (9th Edition) was officially published in July 2024 and became effective on 1 November 2024. This edition, often referred to as "the Bible of electrical installations," replaces the 2021 8th edition and incorporates numerous European Harmonization Documents (HD). Key Overview of the 2024 Edition

Structure: The standard remains divided into 8 main parts, covering everything from fundamental principles to energy efficiency.

Format: It is available as individual fascicles or as a comprehensive volume titled "Norma CEI 64-8 per impianti elettrici di bassa tensione" containing all parts.

Major Update to Part 8: Part 8 has been simplified into a single fascicle, replacing the previous 8-1 and 8-2 sub-parts, focusing on energy efficiency and active prosumer installations. Main Changes and New Requirements

The 2024 update introduces several critical shifts in how electrical systems are designed and verified: nuova norma cei 64-8 - CNI

1. Executive summary

Norma CEI 64-8 (also known as CEI 64-8) is the Italian electrical installation standard for low-voltage electrical systems in residential, commercial and similar buildings. It defines design principles, safety requirements, installation practices, verification and documentation to ensure electrical safety, functionality and compatibility with wiring regulations. This report summarizes its scope, key technical content, 2024 revisions or relevant updates, practical impacts for designers/installers/inspectors, and recommended actions for compliance.

2. Electric Vehicle (EV) Charging Systems (Section 722)

With the boom in e-mobility, the 2024 edition clarifies:

Why is it mandatory?

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).
