Detailed Solution

Fuse placement in electrical wiring should be in live or phase wire.

A fuse is a wire made of a substance that has an extremely low melting point. The wires become heated and melt when a large current travels through the circuit as a result of overloading or a short circuit. Therefore, the circuit is disrupted, and the current ceases to flow.

The fuse is always attached in the live route because it can blow and safeguard the appliance if the live wire gets shorted anywhere inside the appliance and generates a high current.

The appliance cannot be protected if the fuse is linked to the neutral channel. If the fuse is connected to the neutral wire, then due to the excessive flow of current when fuse burns, current stops flowing in the circuit but the appliance remains connected to high potential point of the supply through live wire. Additionally, when a fuse blows due to a problem, attaching a fuse in the live line separates the load from the source.
