Bus Bar current rating is calculated Depending upon cros
section area, Lenth, Voltage

Answer / virrendra

Bus Bar current rating is based on amount of Current to be
carry. The current carring capacity is 1A / Sq.mm & 1.6A/
sq.mm for Aluminum & copper respectively.

Ex if the 200 Amp load is required to be carry then the (20
x 10 MM ) Aluminum strip is required & the same way (25 x
5 MM ) copper strip is Required.

ofcource the length is also play a little part in this
