5. Verification of harmonic capability
A unique feature of Part 6 is the requirement to verify temperature rise under non-sinusoidal currents (harmonics). This is essential for modern loads like LED lighting, VFDs, and UPS systems.
Utility: Generation, transmission, distribution, and conversion of electric energy. Environments: Industrial Plants: Handling high current and complex loads. The Complete Guide to IEC 61439-6: How to
- Design Verification (Type Tests): Performed by the manufacturer to prove the design is sound (e.g., temperature rise, dielectric properties, short-circuit strength).
- Routine Verification: Tests performed on every single unit manufactured (e.g., enclosure protection, insulation resistance, operational checks).

Common Myths About IEC 61439-6 PDF
Myth 1: "Any busbar with a CE mark complies with IEC 61439-6"
False. CE marking claims compliance with EU Low Voltage Directive, but not automatically with IEC 61439-6. You must request the manufacturer’s test report (TTR) verifying the specific type tests. Overview Common Myths About IEC 61439-6 PDF Myth
Key Components: It covers the entire assembly, including straight lengths, joints, tap-off units, and accessories like expansion units or adapters.
