While Design Verification is performed once on a prototype or system design, must be performed by the Panel Builder on every single completed assembly before it leaves the workshop. Routine Verification includes:

Defines how internal compartments separate busbars, functional units, and terminals to protect against accidental contact and limit internal arc propagation. 2. Main Electrical Characteristics Rated Voltage ( Uncap U sub n Uecap U sub e ): Maximum AC or DC voltage thresholds.

Professional organizations provide comprehensive workbooks and specifier guides to help manufacturers and engineers implement these standards:

If you are building a small lighting distribution board (e.g., 160A), IEC 61439-1 + a specific Part (Part 3 for distribution boards) is used. If you are building a 4,000A main switchboard for a factory, you need IEC 61439-1 and -2 PDF together. The international standard governing these systems is

The specific standard for Power Switchgear and Controlgear Assemblies (PSC-assemblies).
