You can if you can find out the consumption in watts or the resistance in ohms.
Amp = watt/volt
Amp = volt/ohm
for AC it's a bit more long winded depending on the phase; plus it's been a while since I've had to think about this... I can remember how to find the wattage for single and 3 phase but for that you need the volts and amps. With any luck someone else with a better answer will turn up or you could try Professor Google.
Good luck and welcome to the forum.
