Enter your electrical parameters to find the correct wire size that ensures safety and prevents voltage drops. Example: 5 light bulbs (60W each) over a 10m copper cable.
Formula: Section = (2 × ρ × Length × Current) / (Voltage × (Voltage Drop % /
100))
ρ (Resistivity): 0.0175 for copper, 0.0282 for aluminium
Minimum recommended wire size for household: 0.5 mm² or higher
