The ground wire should carry no current at all, it is there in case of a short circuit to carry the (short circuit) current back to the breaker panel to trip the breaker. The neutral will carry the unbalanced load current between the 240 volt legs. e.g. L1 and N (neutral) 120 volts the load draws 8 amps. L2 and N (same neutral) 120 volts the load draws 12 amps. The difference between the two amperages is what the neutral will carry 12 - 8 = 4 amps.

∙ 11y agoA wire does not carry voltage. When talking about wire and voltage is it the insulation factor that comes into play. The more insulation around the conductor the higher the voltage can be suppressed on it. Wires carry current or amperage. The amperage that a wire can conduct is based on the cross sectional area of the wire. In North America this is sized by the wire gauge AWG. Now back to the question, yes a neutral can carry a current in a closed circuit. The neutral carries the unbalanced current of the circuit. Two balanced loads with a common neutral will carry no current where as with a unbalanced load the neutral will carry the difference of the two load currents.

Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
How do you build a circuit?
Three main components that are needed to build a circuit will be a power source. This supplies the circuit with a voltage to operate. A load to make the current flow through the circuit, and conductors to join these two devices together to carry the current.
What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
What wire size will carry 50 amps 200 ft 220 voltage?
Actual voltage would be 240V. 4 AWG copper is capable of carrying 50A. At 200 ft, with a 50A load, voltage drop would be about 6V, which is within the acceptable 3% voltage drop for a branch circuit.
How many volts does a brown wire carry?
The three colours used in the UK are: blue (live), brown (neutral), yellow and green stripes (earth). The standard UK domestic voltage is 240 volts.
Why neutral wire does not carry current in closed ac circuit?

Why we don't get shock if we touch neutral wire..we need two wires to close circuit pH and n when circuit closes current will flow around the circuit and one wire gets shocked other not why?
We don't get shocked when we touch neutral and ground because neutral is grounded back at the distribution panel, so the effective voltage between neutral and ground is very low. It won't be zero, because there is current flowing on neutral, causing a voltage difference between the load and the distribution panel, but it is low enough, assuming there is no malfunction, to not cause a shock.In the case of touching hot and neutral, or hot and ground, you will get shocked because there is line voltage between hot and neutral, and because neutral and ground are connected together, there is also line voltage between hot and ground.Note, however, that connecting a load between hot and ground is a violation of the code and the intent of the design, because ground is not rated to carry current except in short term fault conditions - you must always connect a load between hot and neutral, or between hot and hot, as the case may be.
What is the purpose of a feedthrough?
A feedthrough is a conductor used to carry a signal through a circuit board. They have two main catagories which are power and instrumentation. Power feedthroughs are used to carry a high pwer or high voltage. Instrumentation are used to carry a low voltage electric signal.
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.
What will be happen if you use earthing in place of neutral in any circuit?
* * * DANGER * * * DANGER * * * DANGER * * *Do not, under any circumstances, use earth ground instead of neutral in a circuit. Besides being a violation of the US National Electrical Code, and probably the applicable electrical code for any country that has an existing neutral system in place, it constitutes a hazard because the earth ground conductor is not rated to carry operational current. It is only there to carry momentary fault current so as to trip the protective device (fuse or circuit breaker) in the distribution panel. Also, placing operational current on protective earth ground can raise the voltage on that conductor, creating the potential for an electrocution hazard.

What parts are needed to create a circuit?
A basic electrical circuit needs a voltage supply (battery or household outlet), wiring to carry electrons to and from the voltage supply to the load, and a load (motor, light, heat element, stereo, blender, whatever).

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.
When does the current flowing through two different arms in a circuit carry same current?
With the same voltage and resistance the current will be the same value.
What will happen if a piece of string is being used to complete a close circuit?
The piece of string will act as an insulator. Insulators will not carry circuit current when a voltage source is applied across it. Therefore nothing will happen if a piece of string is used to complete an electrical circuit.
Why does not tester light up when it is touched to neutral of 3 pin socket?
Because the neutral is simply the return path in a complete circuit. It doesn't carry any power - that's only found in the live wire.
