YES. ACTUALLY THE SIZE OF NEUTRAL BUSBAR IS BIGGER THAN THE PHASE CURRENT IF ALL THE LOADS IN A 3 PHASE PANELBOARD ARE ALL SINGLE PHASE. In single-phase, which is found in homes, when an appliance is operating, the amps (current) will be equal in the "hot leg" and the neutral. So current IS passing through the neutral wire. In 3-Phase, which is found in a lot of commersial and industrial buildings (including schools), very little current will exist in the neutral IF the current load is BALANCED EQUALLY between the 3 phases. At any given time, however, it is almost impossible to balance the current exactly. So current, even a small amount, will probably exist in the neutral wire. Most certainly enough to harm or kill you! Be it at home, or at work, when the lamp at your desk or by your bed is on, current is flowing through BOTH of the lamp wires!
What else can I help you with?
What is the difference between a neutral wire and a hot wire?
In alternating-current systems, we don't have a 'positive' and a neutral conductor, but a 'line' and a neutral conductor.The neutral conductor is connected to the earth and, so, has a potential of approximately zero volts.The line conductor, on the other hand has a potential of approximately 230 V (in Europe) or 120 V (in North America) with respect to the neutral conductor. For this reason, line conductors are frequently referred to as being the 'hot' conductor.
What is the brown wire on my house wiring?
If you live in Europe, then the brown wire is the line ('hot') conductor; a blue wire is the neutral conductor, and a yellow/green striped wire is the protective (earth) conductor.
Is the ground wire safe to be the hotwire?
No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.
Can a charged body attract a neutral conductor ball hanging on an isolating wire?
Yes, a charged body can attract a neutral conductor ball hanging on an insulating wire. When a charged body is brought close to the neutral conductor ball, it induces opposite charges within the ball through the process of electrostatic induction, causing it to be attracted towards the charged body.
What is the Color of neutral wire in 120 volt circuit?
For wiring in the USA the Neutral conductor is required to be white or gray by the National Electrical Code.

When upsizing wire for voltage drop how much smaller can the neutral wire be the next phase conductor?
The neutral wire should be the same size as your conducters
What is the brown wire on my house wiring?

Is there a neutral conductor in a 3 phase 4 wire wye system?
no
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
Is a neutral considered a current carrying conductor?
No, in a three phase balance load, there should not be any current through Neutral conductor. If it is a 2 wire, single phase system, the Neutral will carry the same current as live conductor if the system has no Earth fault, leak.
Why fuse is not connected in neutral wire?
Because the neutral wire only carries unbalanced currents. The hot wire carries full load currents. Answer for European SystemsThe 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.
Is green ground in an extention cord?
Yes, the green conductor is the colour of the ground wire in an extension cord. The black wire is dedicated to be the "hot" and the white conductor is the neutral.
Is red neutral or live in a 240 volt system?
The colour red designates that the wire is used as a live wire. The neutral wire is identified as white in colour.
Is the ground wire safe to be the hotwire?
No. A ground wire is a non-current carrying conductor and cannot be used for hot or neutral.
Is the neutral conductor of a two wire single phase circuit considered a current carrying conductor?
Sure. In a two-wire circuit, both wires carry equal currents.
Does the ribbed wire connect to the positive or negative on a light fixture?
On a molded 2- or 3-wire line cord the ribbed conductor is the neutral conductor. On a polarized 2-prong plug it will be connected to the wider blade. On some line cords the neutral conductor may have a white stripe instead of ribs.
