Is there any difference in sizing a Wye primary transformer over a Delta primary transformer? For example, I have a 25KVA three phase transformer at 380V. I get 25000/(380*1.73) = 38A. Is this the same whether or not it is a Delta or Wye connected primary?

For the secondary I get 25000/(230*1.73) = 63A. Is this also the same regardless of how the secondary is connected (delta or wye)?
