3 phase 100 amp panel

Can I power 30,000 watts of lighting off of a 3 phase 100 amp panel? Commercial space has 208volt.

Welcome to the forums!

That would be about 83 amps of lighting. A little more than the 80% rule and that's if everything is balanced perfectly. Doesn't give you any room for anything else. How did you come to the 30KW number?

does each leg have 110 volts to ground?

It will likely be 120 to ground, nominal.
OP also posted it as a 208v system, so it is likely a Wye, unless he was measuring from the high leg to ground.

You said about 83A. How many watts would that allow for? A little over 17kW?
