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!

∙ 9y agoIt depends upon the configuration of the electrical system.
For European single-phase systems, having a line and a neutral conductor, under normal (i.e.no fault) circumstances, the neutral wire will carry exactly the same current as the line (not 'phase'!) conductor.
For North American systems, utilising two lines and a neutral, it depends upon the 'balance' of the loads.
For three-phase, four wire, systems, with a perfectly-balanced load there will be no neutral current, but for an unbalanced load, there will be a current -although not necessarily the same as any of the line currents.

∙ 7y agoA neutral wire can and does carry a current on both a split phase and three phase system. The neutral will carry the un-balanced current of the circuit.
Reference the split phase diagram above.
The neutral conductor is the centre point between the L1 and L2 line points. If you have a current of 10 amps between L1 and N (neutral) and 8 amps between L2 and N (neutral), then the un-balanced current would be 10 - 8 = 2 amps.
Electricians will try and load balance a distribution panel by moving circuit loads to different breaker positions within the panel board. The object is to obtain the lowest current draw on the neutral 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.
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.
Is ribbed wire hot?
No, the ribbed conductor on lamp cord is the identified conductor thereby making it the neutral wire.
How do you wire a 3 wire European oven white black green to a US receptacle with 4 wires white black red and bare?
red wire connected to live conductor of supply intake,while the white wire connected to neutral conductor or supply and the bare wire connected to the protective earthing of
What conductor should be grounded in a four wire three phase system?
The neutral.

No, the ribbed conductor on lamp cord is the identified conductor thereby making it the neutral wire.
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
Is there a neutral conductor in a 3 phase 4 wire wye system?
no
How do you wire a 3 wire European oven white black green to a US receptacle with 4 wires white black red and bare?
red wire connected to live conductor of supply intake,while the white wire connected to neutral conductor or supply and the bare wire connected to the protective earthing of
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
What is the color of live wire neutral wire and ground wire in Bangladesh.?
In Bangladesh the color of live is green and neutral is blue and ground is black.
What conductor should be grounded in a four wire three phase system?
The neutral.
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.
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.
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.
