    I pulled a black and sooty 13A fuse out of an extension lead yesterday. It's only ever been used for low-power stuff like hifi but over 35 years it must have got hot at some point.

    A 13A fuse run at 13A for a few hours can get really warm. That just adds to the heat from the plug contacts.

    Any fuse running at its rated current reaches 1085 degrees (the melting point of copper), that's how it works.

    A fuse should carry its rated current indefinately. A 13A mains plug fuse can pass 25A for about 30 minutes before it blows.
