Default Re: 13 amp fuse for 1.5mm mains flex?

Yes, fuses can handle surprising overloads: not that long ago I bought a new washing-machine whose heater is rated at 2Kilowatts. Because I was doing some kitchen-refurb work it stood next to the sink rather than being fitted into its proper space, so I powered it via a 2-way trailing 13A extension-lead which was also temporarily powering the fridge.

It did three washes before the 3Amp fuse in the extension-lead's plug failed!
