Why fuse and switch are connected in a live wire of electric circuit?
A switch or a fuse in an electrical circuit is always connected to the live wire so that the socket or appliance is not live when switched off. This could cause the user to get an electric shock if they touched the inside of the appliance.
Why is the fuse of an appliance always connected to the live wire?
The fuse wire is always connected in the live wire of the electric circuit because if the fuse is somehow put in the neutral wire in the circuit, then due to excessive flow of electric current when the fuse burns, current will stop flowing in the circuit, but the appliance will still remain connected to the high …
Why fuse is not connected with neutral wire?
Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral. Since, neutral is not a live conductor coming from the source, disconnecting a neutral line can only open the current path through neutral. But, the live phase still carries the charge.
Why the fuse wire is always placed at the entry point of current in the series in a circuit?
The fuse or circuit breaker is placed at the LIVE entry point to any device so that if it were to blow it would remove all applied power to the device. Note that COLD and SAFETY GROUND are intended to be intact after LIVE is removed. This latter item is a key safety issue in appliances to prevent electrocution.
Does a fuse wire is always connected in parallel with the main line?
Explanation: Fuse wire is always connected in series to prevent the electrical appliances from damage due to unwanted high current in the circuit.
Where do we connect a fuse — with live wire or neutral wire?
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.
Do you connect fuse in series with appliances or in parallel to it why?
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).
Should fuse be on live or neutral?
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 the fuse wire always connected in the Live Wire?
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.
What happens if you put a fuse in a neutral wire?
A fuse in the neutral (or grounded) power line, or (heaven forbid) the ground, or ‘earth’ connection would potentially make the whole machine live, and make other devices on the same ground line live as well. This is why such attention is directed at the integrity of ground bonding.
What is the purpose of a fuse on a circuit breaker?
The fuse or circuit breaker is placed at the LIVE entry point to any device so that if it were to blow it would remove all applied power to the device. Note that COLD and SAFETY GROUND are intended to be intact after LIVE is removed. This latter item is a key safety issue in appliances to prevent electrocution.
What happens when a fuse blows?
A ‘blown’ fuse isolates a faulty circuit in the same way. It must be fitted after the switch so that there is no danger to the person who replaces it. Now, consider why fuses blow and how devices become faulty. A fuse responds to excessive current. The wire melts (or vapourises!) and the connection through it is broken.
