Spanningsverlies.
Schat het ohmse spanningsverlies, of de doorsnede voor een grens, in één fase en drie fasen.
Copper resistivity is 1/58 ohm·mm²/m and aluminium is 0.0282, about 20 °C. Reactance, temperature and installation ampacity are not included. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.

Estimate resistive voltage drop, or the conductor section for a drop limit, in single-phase and three-phase circuits. Copper resistivity is 1/58 ohm·mm²/m and aluminium is 0.0282, about 20 °C. Reactance, temperature and installation ampacity are not included. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
