Voltage drop calculatorVoltage drop calculator

In this calculator you can easily calculate the expected total voltage drop in cables, and get an indication of the expected percentage of voltage drop in an installation.

In the calculation the standard value for resistivity is set to 0.0175 ohm*mm2/m for copper (cu), alternatively 0,029 ohm*mm2/m for aluminium (al).
