>I'm often amused by the instructions that come with appliances sold in the U.K. along the lines that the plug "MUST be fitted with a 3A fuse" (their emphasis). Yet the same appliance, fitted with the same 0.75 sq. mm cord is now likely to be sold right across Europe, where in most cases it will be connected to a circuit fused at 16 or even 20A.

Paul,
According to my understanding, your 3A fuse is also for Ground-fault protection, whereas by us we have a GFI (we call it a differential) for that.
