While design verification is performed once on a prototype design, routine verification is performed by the assembly manufacturer (panel builder) on before it leaves the factory. This ensures that no manufacturing defects exist and that the unit matches the verified design. Routine verification includes: Inspecting insulation clearances. Checking mechanical operation and interlocking systems. Testing dielectric properties (high-voltage tests). Verifying correct wiring, connections, and labeling.
