someone uses that lead for a 3kw kettle.

No, a fuse dissipates 1W at rated current.

For a 10A fuse (data from Coopers)...
- 1 * In (10A) for min of 1000hrs continuous.
- 1.6 * In (16A) for min of 30min continuous.
- 1.9 * In (19A) for MAX of 30min continuous.

So even with a 10A fuse you can still pull 16A for 30min continuously.


Cheapest is education.

Are you saying we use students as cheap fuses ;-)

Some lecturers could be, only time they would ever be a bright spark...
