Purpose of the fuse is to save circuits from the damage due to high current and voltages caused during fault conditions. These faults affects the live wire. So fuses are kept there. Morever other parts such as ground, do not need this protection, since these high voltages gets automatically earthed.
So that the live wire is isolated when the fuse blows. If a fuse was placed in the neutral, the equipment would still be live when the fuse blows.
A fuse is typically connected to the live wire in a circuit. This is done to protect the circuit from an overload or short circuit, as the fuse will blow or trip and cut off the current flow if there is an issue.
Placing the fuse on the 'live' side helps to disconnect power before it reaches the appliance. This reduces the risk of electric shock when handling the appliance. It also ensures that the circuit is broken immediately in case of a short circuit or overload.
A fuse protects a circuit, equipment, or person by being the 'weakest link'. In case of too much current flowing, it opens, breaking the circuit and not allowing electricity to flow. This prevents a continual overcurrent, and associated heat and fire.
The wire that connects the power source to the rest of the circuit should contain the fuse. This is typically the wire that leads directly from the positive terminal of the battery or power source. Placing the fuse in this wire helps protect the circuit in case of a short circuit or overload.
If a switch was on the neutral wire the live wire would still be at the mains potential even when the switch was off. This would cause on en electric shock when one handles any conductor linked to the live wire
See Discuss Question below.
The live wire is connected to the fuse to ensure that the circuit is interrupted in case of an overcurrent or short circuit, which helps prevent fires and electrical hazards. The neutral wire completes the circuit and does not carry any current in normal circumstances, so connecting it to the fuse would not offer the same protection.
to make sure the protection device such as fuse are connected at the live part
In each live line supply either household automotive or even commercial there is a fuse which when the current exceeds that fuses capacity it blows thus protecting the circuit
Connecting a live wire to ground can cause a short circuit. This can lead to a sudden surge of electricity flowing through the circuit and may result in a tripped circuit breaker or blown fuse, as well as potential damage to electrical equipment and a risk of fire. It can also pose a serious shock hazard to anyone in contact with the grounded object.
