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). Norma CEI 64-8 (9th Edition) was officially published

6. Practical impacts for stakeholders

  • Designers: must incorporate updated protective devices, earthing/bonding schemes, and allowance for EV charging and distributed generation (PV, storage). Provide clearer protective device coordination and selective discrimination calculations.
  • Installers: update installation practices for RCDs, surge protection, cable selection, and special locations; ensure testing equipment and procedures match new verification requirements.
  • Inspectors/certifiers: expect more comprehensive commissioning documentation, updated test regimes, and cross-checks for new equipment types (EV chargers, PV, battery storage).
  • Building owners/managers: need awareness of zones requiring RCDs, periodic testing requirements, and potential need to upgrade distribution boards to support EVs or heat pumps.

Avvertenze pratiche

  • Non fare affidamento su riassunti per lavori esecutivi: usare il testo integrale.
  • Verificare eventuali norme regionali o prescrizioni locali che integrano la CEI 64-8.
  • Quando si applicano soluzioni innovative (es. accumulo domestico, EV charging), verificare anche le normative specifiche del settore e le istruzioni dei produttori.
