Power Engineering: Busbar size and calculation
2) Copper busbar for 2000A, 35 kA for 1 sec withstand – From the table the minimum cross-section needed would be 285 mm2. Thus we can select a 60mm x 5mm busbar as the minimum cross-section. Considering a current density of 1.6A/ mm2 by considering temperature as well as skin effect, we shall require 4 x 60mm x 5mm busbars for this case.
