While IEC 61439-1 provides general rules for low-voltage switchgear and controlgear assemblies, IEC 61439-2 provides specific requirements for power distribution units (PDUs). The key differences between the two standards are:

Testing electrical functionality, interlocks, and control sequences. 4. Temperature Rise and Short-Circuit Considerations

Design Verification (the most critical part, replacing "Type Testing"). iec 614391 and 2 pdf

The organization completing the final assembly and wiring (often a panel builder). They are responsible for routine verification and ensuring the final product matches the original manufacturer’s verified instructions. IEC 61439-1: The Foundation of General Rules

IEC 61439-2 is the part of the standard that deals with low-voltage switchgear and controlgear assemblies - Part 2: Power distribution units (PDUs).
