Home / How to calculate the current of a 10kV busbar sectionalizing cabinet
The formula for calculating the current-carrying capacity of a busbar is: Busbar Current (I) = (Cross-sectional Area * Current Density) Where: I is the current-carrying capacity of the busbar, typically measured in amperes (A). The electrical power system consists of many incoming & outgoing feeder connections, for which busbars are necessary. The busbar sizing calculator determines the required busbar dimensions based on the continuous current rating, short circuit withstand, and thermal limits for switchgear assemblies. On the other hand, oversizing the busbar increases material costs and wastes valuable space inside electrical cabinets.
