In distribution transformers, fuse wires are very thin when
compared to conductor size. How it's possible?

Answer Posted / ramesh kumar k

it is because.... the resistivity of the fuse wire is very
less compare to that of conductor wire...
so the area of the fusewire can be less compared to the
conductor wire...

and fuse wire can't be used for conductor because it will
not have enough mechanical strength..

generally conductor wire is copper and fuse wire of
nichrome...
