I think John once worked out that an extractor fan stalling could not cause enough overload to blow a 3A fuse.
I expect he we remind us.

D'oh. I knew there'd be an excuse.
It's not just "to make me feel better". I present an argument for how it might conceivably one day 'do good', coupled with the fact that, as far as I am aware, there is no way that it could 'do harm'. The only arguments relate to the fact that the likelihood of it ever 'doing good' are extremely small.
Only for very high currents - when, as you say, any fuse would do.
As you imply, human nature being what it is, I would probably just carry on using whatever was already there. However, if I had fitted the original fan, what I would be continuing to use would probably be a 1A fuse!
It's not really an 'excuse' - it's just a reminder that any potential benefit (to the connected equipment) of using a lower-rated fuse only exists if the internal fusing is inadequate.D'oh. I knew there'd be an excuse.
...but how would those currents happen?
Well, the last of them might well happen with a stalled motor - I didn't measure the current (although it was presumably under about 6A, since the 3A fuse did not blow). As I just wrote, I foolishly did not try a 1A fuse with the bypassed thermal cutout - it's far from impossible that such a fuse would have blown before there was irreparable damage to the fan.
It just made me smile - I'll 'like' a different post instead. Taking away likes seems a bit mean.
Oh, fair enough - I thought you were agreeing with his implied criticism - which, as I said, seemed inconsistent with what you'd been saying!
Indeed. I frankly doubt that the presence/absence/rating of fuses in plugs has any significant bearing on the number of people 'killed' in any country.
Controlling your heating/lighting/kettle/fridge/etc using your phone, or a PC in an internet cafe in Ulan Batur.I'm still trying to think of an equivalent analogy. I.e. doing something unnecessary just because you can.
Not "just because one can" but, rather "because one can see a very small chance of it doing some good, and no chance of it doing any harm, at no additional cost".I'm still trying to think of an equivalent analogy. I.e. doing something unnecessary just because you can.
As you say, it costs a bit more, but it could only be justified if you could produce an argument that it might conceivably be 'safer' than using 1.0 mm² - and I think you'd struggle to produce such an argument.
I think that's different, since there will be arguments about the pros and cons of ring finals, no matter what area they are serving.
I might, if I knew what ratings they have, and felt that reducing those ratings might conceivably afford some benefit - but, quite frankly, I haven't got a clue about their ratings
Agreed, but I think you would struggle to find any conceivable safety* benefit (probably quite the opposite) in so doing.
