Why link is provided in neutral of an ac circuit and fuse in pharm of ac circuit?

A link is provided in the neutral of an AC circuit to terminate neutral wires, and a fuse is connected to the live wire to protect the circuit from overcurrent

Neutral link

Neutral link is the end contact for the neutral wires in a circuit.

A construction of a neutral link may differ with the number of the neutral terminations.

Fuse

A fuse is defined as electrical apparatus that provides an electrical circuit protection from overcurrent.

It is of a wire or strip of metal that melts when there is too much current that passes through it, preventing or interrupting the current.

A fuse is usually fitted across the live wire so that the socket or the appliance is unsafe to touch when disconnected.

If a fuse were connected to the neutral wire the appliance will remain linked to the high potential point of supply through the live wire, this will shock a person if he touches the appliance.
