I have a 25KVA 3phase 480V to a single phase 120/240V transformer which is connected to a single phase panelboard. The panelboard is rated at 100A. Considering the fact that I can load the panelboard upto 80A, how should I calculate current referred to primary side of the transformer to size the feeder conductors coming to the transformer.
