Most want something to work, before considering safety.

True, but I have never encountered an appliance not working due to
being fitted with a 1 amp or 2 amp fuse.

Not even a fan heater? ;-)

No - fan heaters are fitted with 13 amp fuses. Generally each element
is 1 Kilowatt.

I had an early colour TV. Said 500w on the back. But needed a 13 amp
fuse...

That's because of the surge when you switch on. Same applies to
anything with a motor, such as a vacuum cleaner. You can't just go by
the rating plate.

Yeahbbut as John Rumm observed futher up the thread, the fuses under
discussion here are effectively slow-blow types anyway, so you *can*
go by the rating plate. I dunno what the (presumably substantial)
inductance of degaussing coils is, but it should provide enough to
limit the inrush current without the need for any thermistors and
whatnot. Even at 50Hz in all probability - but don't quote me on that.

Degauss coils had minimal inductance. Connect direct to mains & the only outcome is BANG
