Last week I met Jean-Paul Lionet, a member of IEC technical committee who participates to the evolution of Low Voltage Switchgear & Control Gear Assemblies standards. Below is the summary he prepared for me. Don’t hesitate to add your comments or questions !
_________________________________________

The IEC 60439-X standards cover all Low Voltage switchgear and controlgear assemblies, i.e. all kind of switchboards and busbar trunking systems. Intended to ensure safety and power availability, they have a long track record of well proven and widely recognized tools, both for design and verification rules and as a reference for certification.
They are now evolving towards a new IEC 61439-X series, aiming to better cover all Assemblies and ensure that the specified performances are achieved.
The main changes may be summarized as follows :
1 – Recognition is made of the evolution of the organization of the industry, between Original Manufacturer and Assembly Manufacturer :
- The conditions for Assembly Manufacturers to benefit from the design verifications made by the Original Manufacturer are stated.
