Would someone please advise me on the correct way to calculate the main protection device required when I have two 25KVA 2 phase 380vac transformers with a secondary voltage of 120vac.
The First transformer would be connected across phase 1 & 2, the second across phase 2 & 3, therefore giving me an unbalanced load.
I understand how to protect it if it was evenly balanced, but what are the calculations when the loads are unbalanced??
Thanks in advance
