Electrical power question about lighting

[jamesheal]

I have a large workshop with 3 rows of fluorescent lamps along it.

Each row pulls 20 amps.

Each row has its own phase.

Question is:- how many amps am I pulling from the main DB and how many kVA?

Thanks in advance for your help!

20A.
kVa = 3*20A*phasevoltage/1000 for kVA (phase voltage is the lower number in a three phase system like 120/208 or 277/480 or 240/415)
