While Part 1 provides the general rules, Part 2 is the specific standard for power assemblies used in industrial, commercial, and similar applications. If you are building a main distribution board or a motor control center (MCC), Part 2 is the document you must follow. Specifically, and IEC 61439-2 form the cornerstone of

To ensure that the assemblies they build are "Design Verified." You cannot claim compliance without following the specific testing and calculation protocols outlined in these documents. If you are building a main distribution board

This part works in conjunction with Part 1 . It adds specific requirements for power switchgear assemblies (typically used for heavy industrial distribution, main switchboards, and motor control centers). Where Part 1 says "general rules," Part 2 says "and here is what is special for power assemblies."

Look for application guides (e.g., from ABB, Schneider Electric, Eaton) that explain the standards in practical terms – but always keep the official PDFs for legal and technical reference.
