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.

Why the fuse is placed in live wire only?
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.
What wire in a circuit should contain the fuse?
The live wire
What does fuses and circuit breakers protect the wire or equipment?
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.
Why is the fuse always on the 'live' side of the appliance?
If there was a fault to earth the casing of the appliance would remain live otherwise. Also there could be a large current from live to earth which could heat the wires to the extent that your house burns down. This is expensive! Neutral is near earth potential anyway. <<>> The fuse should be the first device in any circuit. When a fault occurs the potential across the circuit should become zero to ground. If the fuse was located on the downstream side of the load it would still open the circuit but every part of the circuit upstream from the load would still have a voltage potential to ground. Any one working on the circuit upstream from the load has the potential to receive a shock even though the fuse has opened the circuit. So to answer the question the placement of the fuse in a circuit is for safety reasons.
What happens when you connect live wire to ground?
This is a short circuit which will create sparks. The breaker or fuse on the circuit will likely trip or blow.
Why is the switch for an appliance always placed in the live wire?
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
Why is the fuse of an appliance always on the live side?
See Discuss Question below.
Why should a polarity test be conducted out on a lighting circuit?
to make sure the protection device such as fuse are connected at the live part
What is the working of fuse?
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
What is the work of fuse box?
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
Why is your audio fuse blowing everytime you turn the car on?
A live wire in the audio circuit is touching metal, or connected to ground in some way.
Do you connect a fuse to the live wire or the neutral wire?
You connect the fuse to the live wire as it is the one with the potential difference of 220V and in case of short circuit current will blow out here
