Question

Is there any use of earthing without fuse?

Answer 1

❤❤$\bold{\huge{\red{YES,}}}$❤❤

$<b>Fuses$are not designed to prevent electric shock. They are designed to prevent fires. In the time an over-current takes to heat and blow the fuse, you may be long passed your lethal shock.

GFI's on the other hand compare in and out going current, and trip the circuit if there is any difference all on a timescale much faster than your heart.

Answer 2

yes it is used to prevent us from current by talking out extra current into the ground.
