Why it is dangerous to connect the switch in the neutral wire?
Best Answer It is dangerous to connect the switch in the neutral wire in case of excessive current.
The fuse blows off due to excessive current and the current stops flowing in the circuit.
But the appliance still remains connected to the high potential point of the supply through the live wire..
Where do you connect the neutral wire?
Neutral: The white wire is called the neutral wire. It provides the return path for the current provided by the hot wire. The neutral wire is connected to an earth ground. Ground: The bare wire is called the ground wire.
What are the characteristics of fuse wire?
Fuse wire are used in electric circuits to protect home appliances from damaging by huge amount amount of current. Fuse wire should be such that it melts immediately when strong current flows through the circuit. The same is possible if its melting point is low and resistivity or the resistance is high.
What happens if live is connected to neutral?
If the switch is put in the neutral line (like in your house) the switch and fuse comes in neutral line. In the switch OFF position the entire appliance will have 220V, touching any part will give you deadly shock. As per the rules, if live and neutral are reversed, Electricity board will not give power to your house.
Does the neutral wire carry a current?
To sum up, a live wire carries the full load current, while a neutral wire carries some current, only when the loads are not balanced. … In most installations the live is at the required voltage and the neutral line is connected to ground at some point (so zero volts relative to ground).
What happens if you reverse hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.
Where do we connect a fuse with live wire or with neutral wire?
1 Answer. Fuse is always connected to live wire. If fuse wire is connected to neutral wire instead of live wire then even when the fuse burns out, the appliance remains connected to the live wire and the current supply will not be disrupted due to over loading.
Why fuse is not connected in parallel?
A fuse is nothing more than a short length of wire designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s).
Is a fuse wire is always connected in parallel with the main line?
Answer: Fuse wire is always connected in series.
Is fuse connected to the live wire?
A fuse is usually a thin piece of wire that will melt and break the circuit if too large a current flows through it. … Fuses are always connected in the live wire in an electrical circuit, like switches, and circuits are always switched off before a fuse is changing.
How does a fuse wire protect an electric circuit?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit. …
What is fuse wire?
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
Where a fuse wire is connected?
The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
Why is fuse connected to live wire?
The fuse is connected to the live wire so that the appliance will not become charged (have a potential difference of 230 V) after the fuse has melted due to excessive current. Fuses must be fitted onto the live wire so that when it blows, it will disconnect (isolate) the appliance from the high voltage live wire.
