Not quite sure where that fits in the argument, but always worth the reminder :-)

It's to protect both surely. If it was just there to protect the bike why would there be different value fuses? The reason is to tailor the protection for both the circuitry of the bike and the accessory connected to it. Having a 30 amp fuse with a 5amp piece of wire would do no good. You tailor the fuse to the duty that it's performing. Admittedly a tyre inflator is a good example of where 5 amp would be wrong but using a 30amp fuse on your home lighting circuit wouldn't be a great idea either.
Maybe I'm wrong. I dunno. I give up.
Opinions are like A**holes, Everyone has one. Some people seem to have more than one though which is a bit odd.
