Default Are 3A plug fuses really necessary? Why not always 13A?

Is there a counter-argument?

Thanks,
David.



Here's a counter argument I made a couple of years ago in response to
those that say it's only there to protect the cable.

[It] May not be mandated for appliance protection, but isn't it true
to say that choosing
a plug fuse value sensibly having regard for the maximum current
demand of
the appliance rather than than just the capability of the cable has
always been good practice?

The appliance manufactures seem to think so.

Take the case of three items I regularly install, all with supplied
0.75mm2 IDE cables

A Dell PC with a 5A fuse in the plug
A Cisco router with a 10A fuse
A Brother laser printer with 13A fuse.

Of course this might now create issues with interchangability.
I would be interested to see your comments about the above.
