    Please, how do i select the correct size of a bursar for my feeder panel. I have a transformer rated 500KVA 11kv/0.45kv. I want to connect the low voltage side of the transformer to a feeder panel with three busbars for the three phases and one bursbar for the Neutral that feeds risers. i want to determine the size of busbar i can use in the panel

    Dear sir,

    i want calculations for w x h x d ( 80 x 10 x 1.5 ) mm thick copper bus bar. I want to learn how current capacity is decide based on cross section or dimensions or vise versa. please explain in detail. thanking of you.

    Dear sir,

    i want calculations for w x h x d ( 100 x 25 x 1.5 ) mm thick copper busbar. I want to learn how current capacity is decide based on cross section or dimensions or vise versa. please explain in detail. thanking of you.

      in case of copper bus bar the current carrying capacity is 1.2(max).
      The bus bar 100mm x25mm x1.5mm is suitable for incomer current =(100*25*1.5*1.2)=4500A.
      in case of aluminium bus bar the current carrying capacity is 0.8(max).
      So, the bus bar 100x25x1.5 is suitable for =(100*25*1.5*0.8)=3000A incomer current.

    You need to determine the faul level of the systems and full load current from the customer to determine the CB rating. You can then calculate bus bar rating based on the total connected load supplied by the bus bar and rate you bus bar based on percentages of full load current of connected load. Bus Bar rating are standard sizes based in iEC and IEEE. You have 2500A, 2000A, 800A, 1500A, 600A, 250A, you size bus bar rating based on the three parameters – total connected load of the system, fault level of the system,
