I need to measure the energy consumption of a motor hooked into 3-phase, 208V AC. I know the current on each of the three wires connected to the motor (from a clamp meter). My question is what is the total amp draw of the motor.
For example, I have:
Blue wire: 4.2 amps
Red wire: 3.7 amps
Black wire: 3.9 amps.
Is the total amp draw the simple average of these, the square root of 3 times the average, or something else?
Thank you!
