Busbars can have a cross-sectional area of as little as 10 square millimetres (0. 0 in) in diameter or more as busbars. Aluminium smelters use very large busbars to carry tens of thousands of amperes to the electrochemical. A bus bar is a strip of copper (or) aluminum metal that conducts the electricity in switchboards and also distribution equipment. Instead of using many separate wires, a busbar provides a single, organized path for carrying high current between different electrical components. 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.
