Home / Calculation of the length of the small busbar in the switchgear
The busbar sizing calculator determines the required busbar dimensions based on the continuous current rating, short circuit withstand, and thermal limits for switchgear assemblies. There are two common materials for producing a busbar, they are aluminium and copper. In this guide, you will learn how to calculate bend allowance, developed length, and pre-bend cut length for common busbar layouts, including single bends, offsets, U-bends, and 45° bends. Continue reading to learn the practical formulas and layout examples used for more accurate busbar.
