Low-Voltage electrical installations must undergo a periodic inspection which certifies that all their components are in good conditions and are operating correctly. The compulsory nature of the inspection affects industrial establishments, premises used by the public, sites where there is a risk of explosion, operating theatres, damp premises and the shared areas in buildings containing homes with total installed power in excess of 100 kW.
The inspection procedure is regulated in Royal Decree No. 842/2002 of 2 August passing the low-voltage electro-technical Regulations.
The installation’s Certificate of Conformity guarantees the security of users and employees in the establishment or premises throughout its effective term and ensures the insurance company’s cover in case of a claim.
