I have a 12kW heater which has 3x 4kW 230V elements.
I wire it into Star connection and apply ~3, 400V in order to have 230V phase voltage and the line current is around 18A.
1. How much will the power increase if the heater is wired in Delta at 400V (if it doesn't burn)?
2. What will be the line current if I wire it in Delta and apply ~3, 240V (I suppose the power will remain the same)?
