112 KVA Transformer

[mgtack]

I have a 112 KVA transformer that is primary 208V and secondary 480V. How do I calculate the maximum output for the transformer.
Would it be: input @ 208 volts = 310.89 amps and output at 480 volts = 134.72 amps?

Thanks

Your basic calc is correct.

Correct for 3-phase. Are you sure it's not a 112.5 kva?

Yes thanks, it's 112.5 KVA.

Yes thanks, it's 112.5 KVA.

That's your extra Amp or two for Christmas.

Define "maximum output". You looking for full load or fault current?
