IEC 61439-1 and IEC 61439-2 are the international standards governing (up to 1,000 V AC or 1,500 V DC). They replaced the older IEC 60439 series to provide a more rigorous framework for safety and performance. Key Components of the Standard

The IEC website offers a red-line preview (comparing old vs. new editions) for free, but not the full PDF.

While Part 1 provides the general rules, provides the specific requirements for the most common type of low-voltage assembly: the Power Switchgear and Controlgear Assembly (PSC-assembly). This is the product standard that defines the design, construction, and performance of main distribution boards and motor control centers.

Many reputable manufacturers (like ABB, Schneider Electric, or Siemens) offer free "Guidebooks" to IEC 61439. While these aren't the standards themselves, they provide excellent practical summaries of the PDF requirements. Conclusion iec 614391 and 2 pdf

This is the "umbrella" standard. It contains all the general definitions, service conditions, construction requirements, performance characteristics, and verification methods that apply to any type of low-voltage assembly (up to 1,000 V AC or 1,500 V DC).
