NS Installation Ordinance

Low Voltage Installation Ordinance (NIV)

The revised Low Voltage Installation Ordinance was enacted by the Federal Council on January 1, 2002.

Together with various other standards, it forms the legal basis for the execution and testing of electrical installations.

Safety certificate

Swiss safety certificate for electrical installations (SiNa)

New buildings and renovations:

If electrical installations are newly constructed, modified, or repaired, they must be tested afterwards.

Periodic inspections:

For existing electrical installations, network operators require owners to submit safety certificates at appropriate intervals, depending on the type and use of the installation.

Safety certificate:

Safety must be confirmed by means of a safety certificate and any measurement and test reports from the grid operator.

The safety certificate is a declaration of conformity and confirmation that the electrical installations comply with recognized technical standards and therefore do not pose a risk to people or property.

Minimise hazards
Optimise safety
with independent safety inspections

Electrical installations are undoubtedly among the most reliable helpers in our everyday lives—provided they are in good condition. However, if this is not the case, they can pose considerable dangers to people, animals, and materials, which can have unpleasant consequences for the owners of such systems, such as life-threatening accidents and fires.

Take advantage of our extensive experience and the expertise of our specialists to carry out the safety inspections required by law.

• We at WiKo Wiedmer Elektro-Kontrollen GmbH are recognized as an independent inspection body (inspection register no. 00322 from the Swiss Federal Inspectorate for Heavy Current Installations).
• We check your electrical installations for hazards that may arise in connection with the use of electrical systems.
• We will prepare the legally required safety certificate for you and take care of the administrative tasks with the network operator (EW).
• You will receive useful information on how to handle electrical energy so that you can identify and eliminate hazards at an early stage.

• Ordinance on Low-Voltage Electrical Equipment (NEV) 734.26
• Federal Law on Accident Insurance (UVG) 832.20
• Ordinance on the Prevention of Accidents and Occupational Diseases (VUV) 832.30
• Information from Electrosuisse 3024c

Which devices must be inspected?

• Every 12 months: workshops, construction sites, laboratories, etc.
• Every 24 months: offices, nursing stations, homes, etc.

Photovoltaic systems

A photovoltaic system, also known as a PV system (or PVA), is a solar power system in which solar cells convert part of the sun's radiation into electrical energy. The direct current generated in this process is converted by an inverter and fed into the grid. A larger solar power system is a solar power plant.

Poorly installed and maintained photovoltaic installations unfortunately pose risks of electric shock and fire that should not be underestimated !

In the interests of personal safety, fire prevention, and operational safety, WiKo
carries out the relevant inspection work in accordance with the rules of technology and the training courses of Swissolar, the VSEK (Association of Swiss Electrical Inspectors).

WiKo Wiedmer Elektro-Kontrollen GmbH is registered as an officially authorized inspection body in the VSEK database for PVA inspections .

Which inspection for which system?

Final inspection of the PV system
– Every newly constructed PV system that has been built in accordance with general installation approval NIV Art. 9 or Art. 14 must be fully inspected in accordance with NIV Art. 24.

Independent acceptance inspections of the PV system
– PV systems installed on properties with inspection periods of less than 20 years require an acceptance inspection by an independent inspection body in accordance with NIV Art. 35.

Inspection by ESTI
– In the case of PV systems subject to submission, ESTI checks after completion whether the system has been constructed in accordance with the regulations. The basis for this is the completion notification in accordance with Art. 12 VPeA and the SINA for the DC and AC parts.

PV systems subject to planning approval are: single-phase > 3 kVA; multi-phase >10 kV.

Regulations for KEV systems
– Swissgrid requires certification of system data for the energy generation system.
For systems with outputs of up to 30 kVA, the energy supplier can issue the certification.
For systems with outputs greater than 30 kVA, an accredited auditor must issue the certification.
