What section does the wire need for a 2 A fuse?

Gennady asks:
What section should I take a wire for a 2 ampere fuse?
The answer to the question:
Hello! For a current of 2 amperes, the diameter of the fuse insert should be approximately 0.07 mm. You can also use the calculator on our website https://my.electricianexp.com/en/diametr-provoda-dlya-plavkix-predoxranitelej.html
To translate into a section, you need to multiply the diameter by 0.785. That is 0.785 * 0.07 = 0.054 sq. mm
