Periodic Checks of electrical grounding systems

The D.P.R. n. 462 of 2001 defined a new system of implementation methods for the commissioning, approval and verification of electrical grounding systems, protection devices against atmospheric discharges and electrical systems in places with danger of explosion installed in the workplace. Employers must appeal to accredited Bodies to carry out periodic checks of electrical systems and keep the verification report which must be produced in case of checks.


All employers have a legal obligation to carry out periodic verifications every 2 or 5 years depending on the case (see below). If default occurs (delay or non-verification), criminal sanctions and/or civil penalties apply. The law aims to ensure safety in all work environments with regard to the risks deriving from the electrical system.

ECO Certificazioni was one of the first accredited bodies in Italy to be authorized to carry out periodic and extraordinary verification activities in all the areas foreseen by DPR 462/01:

  • Devices for protection from atmospheric discharge (Area 1);
  • Low-voltage grounding systems (Area 2) up to 1000V;
  • High-voltage grounding systems (Area 3) of plants supplied with voltage above 1000V;
  • Electrical systems installed in workplaces with danger of explosion (Area 4).

With its network of professionals distributed throughout Italy, ECO Certificazioni is the perfect partner to meet the needs of large and small businesses alike.

We guarantee punctuality in our verification activities, thanks to our offices located throughout the territory, as well as technical assistance and cost transparency.
