Am designing a busbar system for my electrical application where the desired current rating is 4000A at 40 Deg amb. Am going with 2 runs of 100X10 CU busbar cross section, as per DIN 43671, the current rating for 2 runs in 2850A, if i multiply with the temperature correction factor for 100 deg is 1.45, then i can able to achieve the 4000A, but the question is do we have restrict the max busbar temperature to 90 deg.
