    Well I would need to do research on that so I can make actual claims here, but I think the switches on the power outlets are somewhat related to the kind of how fuses are handled.

      I think it’s mostly due to the the way the “ring mains” are often wired in UK to basically cheapout of copper I think . . .

      The consumer unit/fusebox/gfci protects the whole ring mains wire from overheating or ground leakage - up to the socket - but that will likely be more current than any individual appliance would want to see maybe 20A or 32A or something. So it’s up to the appliance to protect itself (and its wiring from the plug) from overcurrent scearios per its own tolerances.
