Electrical relationship

Formula

R1 = Rb×Rc/(Ra+Rb+Rc) ; R2 = Ra×Rc/(...) ; R3 = Ra×Rb/(...)

= 14.857142857143

Note

This is a simplified model: it applies the textbook relationship to the numbers you entered and assumes ideal components, steady-state sinusoidal conditions, balanced loads and copper resistivity of 0.0172 Ω·mm²/m at 20 °C. It ignores component tolerances, temperature drift, skin effect, harmonics, inrush, transformer and battery losses, and it is not a substitute for the wiring code that applies where you are. Have any installation sized and verified by a licensed electrician or engineer.
