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.
What else can I help you with?
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.
Do you connect a fuse to the live wire or the neutral wire?
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.
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 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.
What wire in a circuit should contain the fuse?
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.
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 is it important that the live wire not the neutral wire is connected to the fuse?
Suppose there is a fuse which is connected to a live wire and it breaks some day because of excessive power supply. The light goes off because of that. You think that there is no power supply, but actually the neutral wire is taking current towards you. You carelessly try to repair the fuse, and you get a shock. Thus, neutral wires are not preferred in fuse.
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 happens when you connect live wire to ground?
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.
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
