The 2024 update consolidates previous amendments (Varianti) and introduces several updated parts and corrective actions: EV Charging Infrastructure (Clause 753): This is the
- EV Charging Infrastructure (Clause 753): This is the most "modern" addition. With the rise of electric vehicles, the standard now dedicates specific sections to the safety requirements for charging stations in garages and private spaces, addressing specific fire and shock risks.
- Prosumer Installations: Reflecting the energy transition, there are updated guidelines regarding "Active Consumers" (users who both consume and produce energy, e.g., via photovoltaic panels). This impacts how systems are connected and protected.
- Arc Fault Detection Devices (AFDD): The 8th Edition places greater emphasis on fire prevention in specific high-risk environments (like wooden structures or sleeping quarters) by recommending or mandating Arc Fault Detection Devices.
- RCDs and Selectivity: There is a refined focus on the coordination of residual current devices (RCDs) to ensure that a fault in a specific circuit doesn't cut power to the entire building (selectivity).
- External Influences: A much more rigorous classification of environmental conditions (water, dust, heat) helps designers choose the correct IP ratings (Ingress Protection) for equipment.
