The amount of current that a standard copper busbar can carry can be determined by measuring the height and width of the busbar in mm - see ''3'' illustration. If these two values are multiplied it will give a mm² value that can be used with the table for wire ampacity in [[Special:MyLanguage/Overview of wire and overcurrent protection sizing and selection|Overview of wire and overcurrent protection sizing and selection]].

The amount of current that a standard copper busbar can carry can be determined by measuring the height and width of the busbar in mm - see (3) in the graphic. If these two values are multiplied it will give a mm² value that can be used with the table for conductor ampacity from Wire, overcurrent protection, and disconnect sizing and selection.
