Answer for European Systems
The above answer is only true for three-phase systems. In single-phase systems, the neutral carries exactly the same current as the line conductor.
The reason for not placing the fuse in the neutral conductor is one of safety. For example, if the fuse were to blow due to, say, an overload current, then although no current could flow, the entire conductor would remain live and highly dangerous.

Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
What color wire is connected to the silver screw in an incandescent fixture?
In most electrical devices the neutral wire is connected under the silver coloured screw.
Can a burnt out wire cause you to lose a neutral connection?
Not usually. When a wire burns and grounds out the breaker will trip. Wire burns are usually centered around terminal connections points. If a connection becomes loose heat will be produced and this heating action is what burn the insulation on the wire. The neutral wire on the other hand is not switched so it is less likely to have terminal connection points that can become loose. In a circuit the neutral wire is connected under a wire nut with other neutral extensions in the circuit and then connected to the neutral buss in the distribution panel. There is very little to go wrong on the neutral return side of the load wire.
What wire is hot on the cord going to the lamp socket?
The hot wire's cover is smooth and connected to what I call the "button" at the bottom of the socket. The neutral wire's cover has ridges and is connected to the screw shell of the socket.
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.
Should neutral wire of lamp be connected to the 3amp or the 6 amp side of a canopy switch?
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.
Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
What is the colour of the neutral wire in a fuse?
yellow?
Why do white wire mark 120v?
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
How do you know what wire is ground on 200 amp service?
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
Does the neutral wire go on the silver screw when wiring switches or outlets?
No, the switch just breaks the hot side of the circuit. The incoming hot wire should be connected to the top screw and the load side of the switch should be connected to the bottom screw. The neutral wire is usually connected together with a wire nut and pushed to the back of the switch box.
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.
Why is the fuse connected to the live wire?
because current flows through live wire
Where is the neutral wire on a nema 6 20r connector?
The NEMA 6-20R is a 2 pole 3 wire grounding receptacle that is rated for 250 volts. It is not meant to have a neutral wire connected to it. The receptacle is designed to have 240 volts connected to it.
If we connect Fuse wire to neutral how will it affect safety?
prepare to fry
What color wire is connected to the silver screw in an incandescent fixture?
In most electrical devices the neutral wire is connected under the silver coloured screw.
