The fundamental work of IEC 60949 hinges on the physics of heat transfer during a fault. Under normal operating conditions, heat generated by current is dissipated into the surrounding environment. However, during a short circuit, the fault duration is so short (often milliseconds) that there is insufficient time for heat to escape the conductor. The system is effectively "adiabatic"—meaning all the heat generated stays within the conductor itself. The standard uses for area and seconds for time
