# Resistivity (Ohm * mm² / m) at standard operating temp (approx 20-70°C blend) # These values account for typical temperature coefficients in real-world installs. if material.lower() == 'copper': resistivity = 0.0172 elif material.lower() == 'aluminum': resistivity = 0.0282 else: return "Error: Material must be 'copper' or 'aluminum'" cable size calculator

| Current (A) | Min size (mm²) for ampacity | Size if length >50m (VD limited to 3%) | |-------------|-----------------------------|----------------------------------------| | 10 | 1.5 | 1.5 (short) / 2.5 (long) | | 20 | 2.5 | 4 | | 32 | 6 | 10 | | 40 | 10 | 16 | | 50 | 10 | 25 | | 63 | 16 | 35 | cable size calculator

min_area_mm2 = (2 * current_amps * length_meters * resistivity) / v_drop_max_volts
