While full, official copies require purchase, you can find detailed summaries and partial previews at these locations: IEC 60949:1988
Finding a legitimate can be challenging because technical standards are typically copyrighted and sold by the International Electrotechnical Commission (IEC) . However, engineers can access the essential formulas and methodologies through various technical guides and previews. What is IEC 60949?
): A modifying factor is calculated to account for heat dissipation into surrounding layers. Final Permissible Current (
The standard uses a three-step approach to determine the safe current limit for a cable during a fault: Calculate the Adiabatic Short-Circuit Current ( IADcap I sub cap A cap D end-sub
: Material constant (e.g., 226 for Copper, 148 for Aluminum). : Initial and final temperature limits (°C).
): The final rated current is found by multiplying the adiabatic current by the non-adiabatic factor.
