For parts of the electrical installation that will not be accessible when the construction of the structure is completed, inspections and tests of these parts of the electrical installation will be carried out during the construction of the structure. A record shall be drawn up of the inspections and tests carried out of such parts of the electrical installation, and the data that the examinations and tests have been carried out shall be recorded in the construction log.

C.2.2.5. Minutes referred to in point C.2.2.3. together with the minutes of the tests carried out during the construction of the structure referred to in point C.2.2.4. they are attached to the documentation for technical inspection of the building.

C.2.3. Subsequent proof of the technical characteristics of the electrical installation

C.2.3.1. For an electrical installation which does not have the technical characteristics provided for in the design or cannot be established due to a lack of necessary documentation, subsequent tests and subsequent calculations shall determine the technical characteristics of the electrical installation by appropriate application of the standards referred to in point B.4.2, B.4.3. and C.4. and the standards to which those standards refer, and the provisions of this Annex and the specific Regulations.

C.2.3.2. In order to determine the technical characteristics of the electrical installation referred to in point C.2.3.1. appropriate data on electrical installations should be collected to the extent and extent enabling an assessment of the degree of compliance with the essential requirements of fire protection, safety in use, noise protection and energy savings and thermal protection.

C.3. Maintenance of electrical installation

C.3.1. Operations in the context of the maintenance of an electrical installation shall be carried out in accordance with the provisions of this Annex and the standards referred to in this Annex, and by appropriate application of the provisions of Annexes ‘A’ and ‘B’ of this Regulation.

C.3.2. The frequency of regular inspections for the purpose of maintaining the electrical installation shall be carried out in accordance with the requirements of the construction design, but not less often than:

– four years for public buildings, unless a different deadline is stipulated by special regulations,

– four years for electrical installations for safety purposes, unless special regulations stipulate a different time limit,

– fifteen years for buildings or parts of buildings for residential purposes,

– four years for all other buildings or parts thereof.

C.3.2.1. The method of carrying out regular inspections of the electrical installation shall be determined by the design of the construction, and shall include at least:

(a) an inspection involving determining whether all parts of the electrical installation are in working order;

(b) measurements to determine whether the electrical installation as a whole meets the requirements set out in the design of the building, which includes testing the electrical installation using HRN HD 60364-6, the standards to which that standard refers, and the provisions of this Annex, except for the insulation resistance test if the state of the electrical installation does not indicate the need for such testing, and the results of the inspection and the established condition of parts of the electrical installation shall be recorded in the record.

C.3.2.2. An extraordinary inspection of an electrical installation shall be carried out after any change to the same, after any emergency which may affect the technical characteristics of the electrical installation or raise doubts about the usability of the electrical installation and upon request from the inspection supervision.

C.3.3. The replacement of parts of the electrical installation must be carried out in such a way that those works do not affect the existing technical characteristics of the construction.

C.3.3.1. Products replacing certain parts of an existing electrical installation must comply with the requirements of this Regulation.

C.3.3.2. The replacement of the components of the existing electrical installation and their installation shall be such that the electrical installation after installation meets the minimum requirements from the design of the building and this Regulation.

C.3.4. The documentation of the examinations referred to in point C.3.2. and the installation of parts of the electrical installation referred to in point C.3.3. this Annex as well as other documentation on the maintenance of the electrical installation is obliged to be permanently kept by the owner of the building.

C.3.5. A record shall be drawn up about the conducted regular inspection and extraordinary inspection and the electrical installation test, which must contain data in accordance with the requirements of HRN HD 60364-6.

C.4. List of norms

For the execution and maintenance of electrical installations, the standards referred to in points B.4.2 and B.4.3 of this Regulation shall apply.

To check the electrical installation, the standard applies:

HRN HD 60364-6:2007 Low voltage electrical installations -– 6. Part: Verification (IEC 60364-6: 2006, MOD; HD 60364-6:2007)
