Industrial Cable Engineering Suite (Phase-2)
Protective Earth (PE) Conductor Sizing
Based on IEC 60364-5-54 (Table 54.7) for standard installations.
Logic: If S ≤ 16, PE = S. If 16 < S ≤ 35, PE = 16. If S > 35, PE = S/2.
Note: Always verify k1/k2 adiabatic check for high fault currents.
Cable Short Circuit Withstand
Adiabatic calculation per IEC 60949 (Thermally permissible).
Ensure your protective device clears the fault faster than the duration entered.
Parallel Cable Sizing
Determines required runs for high-current applications.
Enter capacity after derating factors.
Cable Tray Fill Calculator
Checks compliance with IEC/NEC 40% fill rule.
Note: 40% is the standard limit for power cables to allow air circulation and heat dissipation.
Cable Weight & Cost Estimator
Estimates conductor metal weight and base cost (Excl. Insulation/Armor).
⚠ Disclaimer: Calculation considers CONDUCTOR weight only. Insulation, filler, armor, and sheath add significant weight (typically +20% to +50%).
