A SCR pulses 480VAC to the above resistive heating element arrangement. Notice, I have 2 seperate deltas 300ohm legs and 2000 ohm legs. NOT SHOWN IN THE ABOVE DIAGRAM IS 575 ohm heaters across L1-L3 and another

575 ohm heater (resistor) across L2-L3. Using an amp clamp, I have 39,39, and 9 amps on legs L1,L2, and L3. How do I calculate what I should have in theory?
