They form the visible part of an electrical system and represent the electrical company having installed the requirements in terms of flexibility and safety for distribution boards are particularly high: Personal protection Property protection High operational and functional safety Ease of useSolid design to prevent unprofitable investment: Optimum adaptability to use cases Cooperation between user / planner / manufacturer to balance specifications and costs6 2 CPC 000 305 L0101 | Work bookStandardTitleEditionIEC 61439 -0 GuidelineApril 2013 IEC 61439 -1 General rules08/14/2011 IEC 61439 -2 Power switchgear and controlgear ASSEMBLIES08/19/2011 IEC 61439 -3 Distribution boards intended to be operated by ordinary persons02/16/2012 IEC 61439 -4 ASSEMBLIES for construction sites11/15/2012 IEC 61439 -5 Assemblies for power distribution in public networks08/25/2014 IEC 61439 -6 Busbar trunking systems05/23/2012 Prestandard IEC/TS 61439 -7 Assemblies for specific applications such as marinas, camping sites.

Who is the manufacturer?Health of the individual is regarded as fundamental asset within the economic space of the European Union. The EU-Commission has therefore made it its goal to elaborate directives, which are then transposed into national law by Member States. Thus, the low voltage directive is implemented in the German Product Safety Act. Next to the German Product Safety Act, there is the Product Liability Act which is designed to pro-tect the user in case of damages. Both laws pursue safety targets and are designed to protect people, livestock and property.

7 Regarding product liability for example, injured parties will only have to demonstrate that their le-gal rights have been violated and that this violation led to a loss and that the manufacturer has intro-duced a defective product to the market and that there is causality between the defective product, the violation of legal rights and the damage. The question whether a manufacturer is responsible for product defects puts an unacceptable burden of proof on the injured is the reason why a reversed burden of proof is applied here. Meaning that the manufacturer has to prove that the product was free from defects in design , workmanship and instructions upon new standard precisely defines the responsibilities for a marketed product.

In case that the ASSEMBLY manufacturer does not install an ASSEMBLY in compliance with the instructions of the original manufacturer, the ASSEMBLY manufacturer will become original manufactur-er for that alteration and will have to carry out the design verification in accordance with the described procedures. The ASSEMBLY manufacturer always has to implement the routine can the original manufacturer or the manufacturer verify the safety of an ASSEMBLY?

9 The new standard describes three design verification processes for ASSEMBLIES and requires a routine verification for every marketed / measurementApplication of constructive rulessuch as electrical mechanical thermal tests in accordance with the requirements speci-fied in the standard such as Calculating of temperature rises or of short-circuit forces Measurement of clearances and creepage distances such as specified dimensions test steps ASSEMBLY sequences based on tested reference designsOriginal manufacturerASSEMBLY manufacturer Original manufacturerASSEMBLYLow-voltage ASSEMBLY TestingCalculation / measurementPower switchgear and controlgear ASSEMBLIESA pplication of constructive rulesRoutine verificationThe ASSEMBLY manufacturer may: Proceed to final ASSEMBLY as provided for by the original manufacturer Deviate from the provisions of the original manufacturer and will thus become original manufacturer for this switchgear ASSEMBLIESIEC 61439 design verification through the original manufacturerWork book | 2 CPC 000 313 B0101 91 How can a low-voltage switchgear and controlgear ASSEMBLY be realized safely?

10 The new standard does not only precisely define the responsibilities of the market participants, but also specifies the dimensions of low-voltage switchgear and controlgear ASSEMBLIES. In addition it presents the possibilities and limits for the market participants in order to guarantee to the user safe low-voltage switchgear and controlgear ASSEMBLIES. It is also designed to specify the documentation required for low-voltage switchgear and controlgear ASSEMBLIES and/or the required verifications.
