I had a chance to look over a bunch of 50KVA transformers here when they were lined up next to the power station before a hurricane. I didn't see any evidence of secondary OC protection or taps to fine tune the voltage, only a selector for the common medium voltages available here. It does make sense that the fuse is in that cut out tho. Thanks. Any idea of what the fuse rating would be vs the KVA of the transformer? 125% of the rated current or would it be higher than that?
