Hi Eric, I understand your concerns but that is how it is nowadays, probably due to the almost wide spread use of the IEC connector. If you designed some equipment to run on 5A say, you MUST employ some kind of protective device inside the equipment as otherwise someone could connect another IEC cable fitted with a higher fuse i.e.13A. I work with some of the most knowledgeable persons in product safety and they all stipulate that the fuse in the plug is only there to protect the cable feeding the appliance. Like a lot of modern rules, they do appear to be rather stupid at times but nonetheless they are there so the best thing to do is, if no appliance protection is fitted, is to fuse at the rating stated on the plate of the appliance. I do that myself but it does not alter the foregoing about appliance cable size and fuse. In that respect I am just the messenger boy, please hold your fire!
