Questions about used 75 kVA pad-mount transformers

How many amps is a 75 kVA transformer?

A 75 kVA three-phase transformer carries 90.2 A at 480 V, 208 A at 208 V and 72.2 A at 600 V at full load. Full-load current is the rating divided by √3 times the line-to-line voltage: 75,000 VA ÷ (1.732 × 480 V) = 90.2 A.
