Copper busbar ampacity calculation.

Ampacities and mechanical properties of rectangular copper busbars. Ampacities and mechanical properties of rectangular copper busbars. This was observed on samples exposed for 60 days in an industrial environment and it is probably identical to that of bus bars in service. Which means take a copper bus bar of 100 mm width and 10 mm thickness the area of the copper bus bar is 10 100 sqmm.

I have worked in a panel manufacturing company for three years the standard current carrying capacity of the copper busbar is 1 2 times its product of width and the thickness. In mcm thousand circ mils skin effect ratio at 90 c 60 hz ampacity amp skin effect ratio at 90 c 60 hz ampacity amp skin effect. This was observed on samples exposed for 60 days in an industrial environment and it is probably identical to that of bus bars in service. Each has a different ampacity for a specified gauge size and these ampacities are found in nec table 310 15 b 16 for the calculations in this app.

The number of sizes shown are not as extensive as those in the tables of ac ampacities and there may be slight discrepancies between. There are a number of considerations that need to be recognized beyond the figures given in the chart. The following tables have been provided by the alliance for telecommunications industry solutions atis t1 committee and represent ampacities for busbar sizes and arrangements typically found in the telecommunications industry. For example 3 0 awg copper has an ampacity of 200 amps at 75 while 3 0 awg aluminum has an ampacity of 155 amps at 75.

Quick busbar selector knowing the ampacity designers and estimators can get the approximate bus bar size. Ampacity of the bus bar selected must then be verified by checking table 1. Quick copper bus bar design selector knowing the ampacity designers and estimators can get the approximate bus bar size.
