Luke,
You are still alive after all
That's a pretty serious transformer. My 15A (call it 4kVA) Variac takes out 13A fuses and 32A Type B Breakers at switch on. I run it on a 16A Type C Breaker. That's usually OK. I think you'd need a big supply unless you can arrange to switch it on gently. Once youv'e managed that you'e only got the magnetising current plus the load current. On the other hand a fault on the Secondary side would still produce a serious fault current. I'd leave it alone.
