IEC 61439-6:2012 is the international standard governing low-voltage busbar trunking systems (BTS), commonly known as busways. It defines the requirements for safety, technical characteristics, and verification procedures for power distribution systems used in industrial, commercial, and residential settings. Scope and Applications

• Built-in components (circuit breakers, fuses in tap-off units).
• Insulating materials.
• Accessible external enclosures (to prevent burns to operators).
• Busbar conductors themselves.

• BSI (British Standards Institution)
• DKE (German commission)
• AFNOR (France)
• SCC (Canada – CSA C22.2 No. 61439-6)
• SAI Global (Australia)

• Busbar trunking systems (BTS) with a rated voltage up to 1000 V AC and 1500 V DC
• BTS with a rated current up to 6300 A
• Accessories for BTS, such as connectors, taps, and terminations

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. such as connectors

IEC 61439-6:2012 replaces the older IEC 60439-2 standard. It aims to harmonize the requirements for busbar trunking systems with the general rules laid out in IEC 61439-1 Built-in components (circuit breakers
