Systematic tests always carried out with devices
Low-voltage switchboards or, in accordance with the standard, power switchgear and control-gear assemblies are developed, manufactured and tested following the specifications of IEC 61439-2.
Requirement of the IEC 61439-2 standard
In order to provide evidence that the switchboard is fit for purpose, this standard requires two main forms of verification – design verifications and routine verifications. Design verifications are tests carried out during the develop- ment process and are the responsibility of the original manufacturer (developer). Routine verifications must be performed by the manufacturer of the power switchgear and controlgear assembly on every manufactured switchboard prior to delivery.
Design verification with tests
The SIVACON S8 low-voltage switchboard offers safety for people and plant by means of the design verification with tests according to IEC 61439-2.
The physical properties are dimensioned and verified at the testing laboratory for both operation and failure situations. Design verifications as well as routine verifications are a decisive part of quality assurance, and the prerequisite for CE marking according to the EC guidelines and laws.
The design verifications can be provided by way of three different methods. If there is more than one method available for a specific verifi- cation, these methods are considered equivalent, and the selection of the method is under the responsibility of the original manufacturer.

Verification of temperature rise
One of the most important verifications is the compliance with the temperature- rise limits. This verifies that the switch- board is fit for purpose when the temper- ature rises due to operational power loss. In view of the ever increasing rated cur- rents, together with higher requirements relating to the degree of protection and internal separation, this is one of the greatest challenges for the switchboard.
Although the standard allows the verifi- cation by calculation for rated currents up to 1,600 A, for SIVACON S8 this verifi- cation is always performed by testing. Clear rules governing the selection of the test specimens (worst-case test) ensure that the entire product range is systemat- ically covered, including the devices.
