AC / DC Voltage Drop & Cable Sizing Calculator
Size electrical conductors accurately by calculating line impedance, resistance, percentage voltage drop across long runs, and compliance with the 3% branch circuit standard.
Circuit Parameters
Calculation Steps
Based on copper resistivity at operating temperature (0.0214 \(\Omega\cdot\text{mm}^2/\text{m}\)).
Calculated with power factor \(\cos\phi = 0.88\).
Joule $I^2 R$ heat dissipated into the raceway/tray.
