It may be over-specified, but I'd say it is under-engineered not over!

Given that it IS specified as 13A, if you run it at 13A it is only just capable. A bit of tarnish on the contacts, a bit of spring weakening, and it gets hot, making both these problems worse. It just doesn't quite do what it says on the tin.

With less powerful appliances, as you say, things are OK. So if we redefine the amp so that 13 new amps = 10 present amps, then it's fine! (Just need to thin-down the fuse wire in the 'new' 13A fuses).
