Welcome in the section of Frequently Asked Questions (FAQ).
01. What is an electrical inspection?
Revision means all measures that verify the compliance of the finished electrical installation with the relevant requirements of IEC 60364. Revision includes inspection, testing and preparation of an inspection report (ČSN 33 2000-6 ed.2).
02. What are the types of inspections?
The types of revisions are as follows: initial, regular and extraordinary.
03. Who can carry out inspections?
Inspection activities are carried out by inspection technicians on the basis of authorization obtained from the authorized organization of the Technical Inspection of the Czech Republic.
04. When do I need an inspection?
You need an initial revision if you are commissioning dedicated electrical equipment. E.g. if you are applying to connect a new apartment or house to the distribution network, then you need an initial revision of the electrical installation. Certain types of objects and installations have prescribed periods for regular revisions.
05. What is reserved electrical equipment?
Reserved electrical equipment is electrical equipment for the production, transformation, transmission, distribution, distribution and consumption of electrical energy and electrical installation of buildings and technologies.
06. What documents do I need to provide for the inspection?
According to the regulation NV 190/2022, the following documents must be supplied for the inspection of reserved electrical equipment::
Initial inspection:
- as-built project or drawing documentation of the actual implementation of the reserved electrical equipment, a technical report for the documentation
- protocols on the determination of external influences, if they are not part of the as-built documentation
- initial inspections of those parts of the dedicated electrical equipment of the object, the operating set (sub-operating set), which as a whole are gradually prepared for commissioning
- records of inspections and tests performed on dedicated electrical equipment during its assembly
- records of the measures taken, inspections and tests carried out during the reconstruction of reserved electrical equipment, which cannot be without voltage for serious social, national economic or technological reasons for the entire duration of the activities, or the opinion of an authorized organization or expert
- risk calculation for equipment designed to protect against the effects of atmospheric electricity with the inclusion of the assessed lightning and surge protection system (hereinafter referred to as “LPS”) in the relevant LPS class according to standard values, a technical report containing LPS documentation, a description of the design including technical drawings, accompanying technical documentation of individual used components proving their suitability for use in a given LPS class by meeting normative values and conditions for maintenance
- verification protocols for embedded products
- identification of the legal entity or person doing business, including the license number that performed the electrical installation
Regular or extraordinary inspection:
- as-built documentation of dedicated electrical equipment and maintenance conditions
- protocols on the determination of external influences, if they are not part of the operational documentation
- records of inspections during the maintenance
- previous inspection report
- inspection reports of authorities
- TICR certificate for class I. reserved electrical installations
- reason of extraordinary inspections
Of course, this is a complete list of documents according to the regulation, which may be required in some cases, however, it is clear that some cases will not be covered by all these requirements. It is different when a standard house is being inspected or when a new industrial factory is being inspected.
07 What does the inspection consist of?
The inspection of electrical equipment consists of an inspection, tests (measurements) and the preparation of an inspection report, where it is then determined whether the specified electrical equipment meets the safety requirements and is suitable for operation.
08. When and how do I pay for the inspection?
After the inspection, an invoice is issued. Unless otherwise agreed, you will receive a completed audit report after payment of the invoice.
09. How can I communicate with the technician?
