Why is the fuse not connected to the neutral wire?

Since, neutral is not a live conductor coming from the source, disconnecting a neutral line can only open the current path through neutral. If the circuit has any other conduction path, the complete current still has to flows through the fuse. Thus, a fuse connected in phase can provide all over protection.

Why the fuse must be in the live wire and not the neutral wire of a circuit?

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.

Should the neutral wire be fused?

A single fuse in the neutral conductor provides protection for neutral-to-phase faults, but not for phase-to-ground faults. This is one reason why a single fuse in the neutral is not permitted.

Can we connect fuse wire with neutral wire?

Hint: A fuse is a device that is used to protect electrical appliances and circuits from damage. Its work is to detect any kind of short circuit and stop the flow of current from that circuit. Complete answer: So a fuse cannot be connected with a neutral wire.

Where do we connect a fuse with live wire or with 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.

Why are fuses connected in series?

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).

Why is the fuse connected to live wire?

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.

Where do we connect fuse with live wire or neutral wire?

What is fuse neutral?

A. fused neutral. is a problem that occurs with very old panels. In early electrical work, people thought that if a fuse on the black wire was good, putting a second fuse in the circuit on the white wire would be even better. This was later recognized to be a bad idea and is no longer permitted.

Why is fuse connected to 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 must the fuse be attached to the live wire?

Once the fuse has melted, the circuit is broken and no more current flows through the device. The fuse or circuit breaker must be connected in the live wire side of a domestic circuit to ensure that it keeps high voltage from reaching the user, or surroundings, if a fault develops.

Which wire is the fuse connected to and why?

live wire
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.

What happens if you put a fuse in the neutral wire?

If you connect a fuse in the neutral and if it blows due to any reason, the electric current is broken. The electrical equipment connected stops working due to lack of current flow though the line voltage is present in the equipment.

What causes a fuse to blow out in a light switch?

If the fault is on the neutral wire between the lamp and the fuse provided in it, the fuse will burn off because the neutral wire is at slightly higher potential w.r.t earth and thus the fault current will flow through the neutral wire and the fuse wire blows out.

Why is a fuse placed in the electric line?

Hence fuse is to be placed in electric line only so that both voltage & current can not be present in the equipment if the line fuse blows. A double-pole circuit breaker which would cause both line and neutral to open if there was a fault, may be used. But a fuse can ‘blow’ without the other blowing.

Can you Fuse a stepdown transformer to 120V?

Therefore, you use a stepdown transformer to 120VAC, but the leg that would be neutral and connected to ground, must float, and therefore should also be fused. Isn’t this essentially a “fused neutral”?
