Testing of electrical installations

The employer is obliged to periodically test electrical installations at least once every 4 years. This obligation stems from the Technical Regulation for low-voltage electrical installations (Official Gazette 5/10). If the employer cannot present the documentation on the conducted tests, a ban on working in the workplace will be ordered during the implementation of the inspection.

An extraordinary inspection of the electrical installation should be carried out after every change or addition, that is, after every extraordinary event that can affect the technical properties of the electrical installation and upon request of the inspection supervision.

Electrical installations can at certain times represent a source of danger to the life and health of persons who come into contact with them, or the equipment connected to them, and they can also represent a source of fire, the consequences of which can be extremely harmful.
