For Aluminum bus bar, multiply 0.6 X breadth X thickness to
get current carrying capacity.

For copper bus bar, multiply 1.2 X breadth X thickness to
get current carrying capacity.

Answer / shri

Bus bar current rating in normal is calculated based on incommer braker rating.
For ex: 800A MCCB incommer
Then bus bar rating will be 800/0.8
I.e 1000A Al bus bar.

Answer / arvind

current capacity is depend on current and how much current
capacity do you want to take.

if flow of electrons is current then why their direction are different???
