This may be a daft question but do 1A fuses really give any useful extra protection over 2A fuses?
Under short circuit conditions there is no useful difference. Under overload conditions there might be but is it a useful amount? I think useful might be defined as stopping something burning out, such as a mains tx. On the margins a 1A fuse may give an occasional extra save but I think this will be rare.
This is largely gut feeling. If anyone can back an argument for or against with real numbers that would be useful.
