None of this is an exact science. It seems that fuses are flawed to a degree. For example a 13 amp fuse can work way above its specification, pulling 20 amps continually without failing. So when does a 13 amp fuse fail ? I can't find any information with exact tolerances. But this would suggest a safety issue, if your cable fails even when it is within the allowed parameters for the fuse value used.
