The neutral wire is an integral part of a functional electrical circuit.
If it’s the wrong size or improperly connected within the system, this can have a direct impact on how well the wire works.
To better understand the neutral wire’s role, it’s important to ask the right questions. This includes, does the neutral wire carry current?
The neutral wire does carry current. it is responsible for completing the electrical flow through the circuit. The hot wire current needs an outlet to return to its source, which is where the neutral wire comes into action.
If the neutral wire is not correctly in place, this gives the hot wire current no return path. In such a case, the circuit will not work.
Here is more on what a neutral wire is all about.

Does A Neutral Wire Carry A Charge?
The neutral wire does carry a charge. It acts as a return path for the hot wire current. Due to the speed at which the current travels within a closed circuit, both the neutral and hot wires hold a charge. It’s important to note, the neutral wire is linked to the ground wire.
It is this reason that makes a neutral wire dangerous if it’s touched.
It’s important to have the grounding wire properly installed for the circuit to work. There are strict regulations in place when it comes to how the neutral wire is set up alongside the hot and grounding wire.
If there are any mistakes in this regard, it can pose a safety risk. The best course of action is to assess how the neutral wire functions within the circuit and ensure the current has a clear path to its source.
This ensures the load will go through as intended.
Does Neutral Wire Carry Current In Single-Phase?
Yes, the neutral wire does carry current in a single-phase setup. It is expected to carry the same current as the hot wire. On the other hand, if there is a three-phase setup, the current will be evenly balanced between the three meaning a neutral wire is not required.
It’s important to understand how the phase conductor works within the setup.
If the neutral wire is not set up properly, this can have a direct impact on how the current flows. Remember, the goal of the neutral wire is to help give the current a natural return path within the circuit.
If there is no return path, the circuit will not function as intended.
For a three-phase setup, the neutral conductor is not required since the multi-phase design ensures the current is balanced.
Does Neutral Wire Carry Voltage?
Neutral wires do not carry voltage and are specifically mentioned as “zero voltage” conductors. The core responsibility of the neutral wire is to offer a zero voltage reference point while also allowing the current to return to its source.
It’s important to note, the current is still there as it returns through.
Due to this, making contact with a neutral wire is still dangerous with a live electrical circuit. It’s recommended to make sure the neutral wire is set up correctly and is linked to the ground wire.
Where Does Neutral Current Go?
The neutral current goes to ground. This is a zero voltage reference point within the circuit and a return path for the current. As the current comes to the neutral wire, it will go to the ground wire as these wires are interlinked.
This is how the “circuit” is completed.
Let’s assume the neutral current does not have a path to go to ground. What happens in this situation?
The neutral current still requires an outlet as it will flow through the neutral wire. Unfortunately, this makes the electrical circuit incredibly dangerous for humans. Any contact with the neutral wire can lead to a shock.
This is why the ground wire is mandatory.
Final Thoughts
Does the neutral wire carry current?
A neutral wire does carry current. This is due to the current needing a return path within the circuit. If there is no return path, this can leave the current exposed within the circuit causing it to become a safety concern.
This is why any electrical circuit that’s created requires a hot, neutral, and ground wire. There are regulations in place to ensure that is the case.
It’s important to know that a neutral wire does carry current and can shock you too. It is dangerous to play around with the wire on your own due to this reason.
