IEC 61439-6 is a standard that specifies requirements for low-voltage power distribution systems, particularly for busbar trunking systems (BTS) and cable distribution systems. The standard is part of the IEC 61439 series, which provides a framework for the design, manufacture, and testing of low-voltage switchgear and controlgear assemblies.
