Default Are 3A plug fuses really necessary? Why not always 13A?

(if the circuit were protected by a BS3036 rewireable fuse, or the
circuit a tad out of spec, the flex longer or thinner etc then the fuse
in the plug would be essential).


And this is part of the reason why appliance flexes are so short
nowadays: not only is the manufacturer saving a few pennies but they're
ensuring the flex is short enough with low enough resistance for a fault
current to blow the 13A fuse in the plug.


or more likely needing to be short enough to open a 16A MCB (that and
being cheapskates!)

(short leads on power tools get on my tits!)
