Yes, and I can really see a 80 year old 'Granny Mabble' doing that,
her replacing a 3A fuse with a 13A one is almost a certain bet at
somewhere....

So? Most appliances will cope with a 13A plug fuse - they have to, to
cope with 16A or 20A radial circuits.

You still seem obsessed with plug fuses. Unlike most radial socket
systems, which evolved from a hodge-podge of accessory designs, the
British ring circuit with fused plugs was *designed* from the outset to
be a coherent and well-engineered system.
