Answer / Ravi Prakash Srivastava

The busbar dimensions 40X8X2 suggest that the busbar has a cross-sectional area of 40mm² (square millimeters), a width of 8 times the cross-sectional area, and a height of 2 times the cross-sectional area. This means that the total area of the busbar is 40mm² * 8 * 2 = 6400 mm². Given a current density limit for busbars, this dimensions can support a load of up to 400 Amps.
