What size busbar should be used at the top of the cabinet

As current flows through the busbar, resistive heating (I²R losses) causes the busbar temperature to rise above ambient. The busbar sizing calculator determines the required busbar dimensions based on the continuous current rating, short circuit withstand, and thermal limits for switchgear assemblies. Figure 1: Busbar Standard The IEC 61439 standard applies to busbar assemblies that will be installed in electrical applications with a.
