Let’s say you are designing a data center with 4000A busbar trunking. Here is how the guides your work.
IEC 61439-6 standard specifically defines the requirements for low-voltage busbar trunking systems (BTS)
The standard is designed for , as well as for controlling energy-consuming equipment. It applies to systems where the rated voltage does not exceed 1,000 V for alternating current (a.c.) or 1,500 V for direct current (d.c.) . iec 61439-6 pdf
Specifiers and end-users need the standard to write correct tender documents. Without it, you might accept a system that fails under harmonic loads.
Busways must survive the massive electromagnetic forces generated during a short circuit. The standard requires verification of: Rated short-time withstand current ( Icwcap I sub c w end-sub Let’s say you are designing a data center

These sections provide specific modifications, additions, or replacements to the general rules for particular types of equipment. It applies to systems where the rated voltage
