The permissible busbar temperature is decisive when dimen-sioning the busbars. The busbar temperature is dependent on the current and the current distribution, on the busbar cross-section
For busbar sizing, the primary references are IEC 61439 (for low-voltage switchgear and controlgear assemblies) and IEC 60287 (for current-carrying capacity of cables). IEC 61439 is a standard develop...
