Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.

This can occur in many ways ( source):
- Coming in contact with the hot wire while also in contact with the neutral wire will cause current to pass through your body.
- Contact with the hot wire or anything energized by it and a grounded object will cause a shock.
- Contact with electrical components or appliances that are not grounded properly can shock you.
How do you determine which wire is the neutral wire?
Neutral Wire. Once hot wire has initialized the beginning of a circuit, there must be another wire to complete the circuit. This role is filled by neutral wire. Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel.
What does the neutral wire do in an electrical circuit?
What is the difference between neutral and ground wires?
Does the neutral wire consider a hot wire?
What is the neutral wire used for?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.
Is neutral wire necessary?
The presence of a neutral wire is not required (many computers do not have a neutral wire connection). Grounding problems only exist in computer installations when two separate pieces of grounded equipment are interconnected through data communication lines.
Does a neutral wire carry current?
A hot wire is a wire that will provide the electric source and it will be alternating current. The neutral wire will be connected to the earth ground, the color of the neutral wire could be grey or white. During normal operations, the neutral wire will carry current.
Is neutral wire same as ground?
Neutral wire acts as a return path for the main AC while Ground acts as a low impedance path to “ground” fault current. Neutral is normally a current carrying conductor whereas Ground is normally not a current carrying conductor.
Will a light work without a neutral?
The neutral wire allows the completion of the circuit and the switch to have power even when it's turned to the off position when you want the lights off. Without this neutral wire in place, the circuit is broken any time the switch is now in the off position. It remains has power when the switch is in the On Mode.
What happens if no neutral wire?
Without the neutral wire, all sorts of instabilities occur in the system like unstable voltages, unexpected currents and even dangers of electric shock.
Do neutral wires have voltage?
The neutral wire is often said to have zero voltage on it. If you touch that wire on a live system, however, you will often find out very quickly that technically having zero voltage is very different from meaning there is no electricity present.
Is neutral wire safe to touch?
If you touch the neutral wire in a live circuit, whether it be a lamp, an appliance or something else, it is the same as touching the active wire. It is only "safe" to touch the neutral wire when there is no current flowing, just as it is "safe" to touch the earth wire (when one exists).
Can you get electric shock from neutral?
Now, we know that neutral is always connected to the ground or earth. So when touching the neutral wire standing on the ground there is no voltage applied to our body, therefore no current flow through our body and we do not get the electric shock.
Can I connect neutral and ground together?
No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.

Can I use ground instead of neutral?
a ground and a neutral are both wires. unless they're tied together with other circuits, and not a 'home run' back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.
