Unlike basic adiabatic calculations that assume all heat remains trapped within the conductor during a fault, IEC 60949 accounts for non-adiabatic effects. This means it factors in the small amount of heat that escapes into surrounding materials (like insulation or screens). The standard uses a multi-step approach:
