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.

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
