Electrical installation audit

Be certain that your electrical installation is safe to use

Electrical installation audit is a legal obligation

According to the law, the condition of an electrical installation must be checked if you wish to use a new electrical system. An audit is not required for temporary installations with a main protection of less than 35 amps and for extensions to an existing installation if the protection in front of the supply line is less than 35 amps.

After a certain period, regular or extraordinary audits of the electrical system are required, depending on the type of building and the year of construction.

An audit is also required to obtain an authorization of use for the building.

Why do all electricity systems have to be re-examined at intervals?

  • The hazards of the electrical system may go unnoticed without regular inspection, becoming visible only when a hazardous situation is already in progress.
  • The insulation of wires ages and the electricity system is affected by environmental conditions. Therefore, it is advisable to have the electricity system inspected more thoroughly by specialists from time to time in order to avoid hazardous situations.
