Professional busbar sizing calculator with current-carrying capacity per IEC 61439, temperature rise analysis, short-circuit withstand (thermal & mechanical), skin/proximity effect derating, voltage drop, bolted joint analysis, and copper vs aluminum cost comparison. The current rating is calculated from the conductor cross-sectional area, material (copper or aluminium), and maximum. The International Electrotechnical Commission (IEC) issues globally accepted standards that promote safety and efficiency in electrical engineering. For busbar sizing, the primary references are IEC 61439 (for low-voltage switchgear and controlgear assemblies) and IEC 60287 (for current-carrying.
