This does not factor-in the heat from a populated fuse box, but does include the heat from the current load with the proper rerating. **System Level Temperature represents the ambient temperature of the fuse box at a location within the vehicle. The temperature within a populated fuse box (in a given location) will be higher. The limiting factor is the plating. Sn-plating’s temperature limit is ≈130°C, and Ag-plating allows up to 150°C at the terminal interface.
