Measure with a true rms clamp meter. Youíll get incorrect readings if it isnít true rms.

We run about 19kw at idle on our 3phase 30kw rig

75amps at 240v is 18kW so Iíll say that in the same ballpark.

FWIW, the furnace canít pull 30kW at higher temps (2300F). The resistance of the elements at that temperature restrict it to about 26kW
