Periodic inspections of earthing systems in companies with at least one employee are governed by Presidential Decree 462/01, a regulation also governed by Legislative Decree 81/08 which protects the safety of employees in the workplace.

The Employer has the obligation to approve the electrical system and to appoint a body authorized by the Ministry of Economic Development to carry out periodic checks of the system every 5 years or 2 years (in the case of premises used as medical offices, places with greater danger in the event of construction site fires).
In the absence of employees, the obligation governed by the CEI 64-8/7 standard to carry out checks to check the correct efficiency of the protective devices remains.

SF Consultancy and Planning has Inspectors authorized to carry out checks who do not carry out conflicting activities as regulated by ministerial provisions in order to guarantee a truly impartial third-party inspection. The periodic verification of electrical systems subject to Presidential Decree 462/01 consists of the following activities:

1. Check of the documentation relating to the system (declarations of conformity, complaint, project and previous verification reports).

2. Visual examination.

3. Continuity test of earthing, protection and equipotential conductors.

4. Instrumental tests of correct functioning of the residual current circuit breakers (the so-called "circuit breakers").

5. Measurement of earth resistance.

6. Measurement of fault loop impedance (if and when applicable).

7. Measurement of contact and step voltages (if and when applicable). With this control activity, the administrator is better protected against electrical risk.
