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. iec 61439-6 pdf

The new standard introduces a strict regime of Design Verification and Routine Verification .

Clause 8.5 requires the system to withstand Icw without damage. For a 4000A busbar close to a transformer, the prospective short-circuit current may be 80 kA. Ensure the selected BTS has Icw ≥ 80 kA. Applying a high-voltage test to confirm insulation integrity

In modern infrastructure, busways often pass through walls and floors that serve as fire barriers. IEC 61439-6 defines requirements for:

: Rated voltage not exceeding 1000V AC or 1500V DC. The new standard introduces a strict regime of

When manufacturers submit product catalogs, they include reference numbers to ASTA, KEMA, or TÜV test certificates. Engineers use the PDF standard to cross-reference whether the tests conducted match the specific clauses mandated by Part 6 (such as the mandatory crushing test or fire-barrier test).
