I have a countertop 15 amp GFCI receptacle in my kitchen and I would like to replace the fuse for it.
It's currently on a time-delay 30 amp fuse (it's a cartridge/capsule style fuse), which is too much, since the wire going to the receptacle is 12 gauge aluminum (which as far as I know is rated for max 15 amps).
My question is, should I use a time-delay fuse or a fast acting fuse for this receptacle?
I've read that time-delay fuses are for appliances which may have large electric motors, but I'm not sure what's considered large in this context. The outlet will connect things like a toaster, kettle, blender, slow cooker, microwave, etc. This receptacle is the only one on this circuit.

Yes, use 15A time delay, the short inrush of motors will not damage the wire. In the US even circuit breakers operate on a time delay, they call it "inverse-time", which really means the same thing.
Not sure what type of fuse is used in your country, in the US a FRN15 fuse would have a similar 500%/10 second delay that a typical thermal magnetic breaker would trip.
