Hello Glenn, Two things complicate this question. One is specific to the U.K. In the UK all domestic and very many commercial and light industrial use a ring main for all socket outlets and therefore we do not have spurs with ratings. UK plugs have fuses in them because the protection on the ring main is much higher than the rating of the plugs. The second applies to all of Europe and conncerns fuses and other circuit protection. The rating of a UL rated fuse is more or less the current at which it blows. The rating of a fuse to IEC 127 (used throughout Europe) is more or less the working current of the fuse and the circuit it protects. Thus circuits are used right up to the full rating of fuse protecting them
