Well, honey, if you connect the earth wire instead of the neutral wire in a lamp, it ain't gonna glow. The earth wire is there for safety, not for powering up your light bulb. So, if you want that lamp to shine bright like a diamond, you better stick with the neutral wire where it belongs.
Physically yes, but to no avail. The breaker will trip instantaneously as a short circuit will have been introduced into the circuit with this action. In all wiring the live must never be connected directly to earth. The only place where the neutral and earth are connected together is at the distribution panel where the utility's supply neutral joins the system earth on the distribution panel's neutral bus bar.
In a three phase system, connected wye, neutral is the common return, and it is grounded. In a delta connection, there is no neutral.
The neutral wire completes the circuit and carries the current back to the power source. It provides a path for the electricity to return safely to the earth or ground. In a 3 pin plug, the neutral wire is usually color-coded as blue.
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.
If there's no earth leakage protection unit in your main Distribution Board then the device will operate normally since the neutral and earth conductors are one on the supply side. But if there's Earth Leakage then because of the imbalance in the currents flowing through the Earth Leakage it will trap. What is called 'earth wire' in Europe is called 'ground' in the US and is often bare. Using a bare conductor as a neutral exposes you to potential shock. If the bare wire is properly connected at the panel, all is fine. But if you touch this bare neutral and provide a better grounding connection than the panel provides, you become part of the circuit to whatever device that circuit supplies. What is often missed in this scenario is that with the neutral being after the load, the load limits the current and your shock WILL NOT TRIP THE BREAKER.
You can not have a "neutral earth" the "neutral" and the "earth" are separate wires/connections and should not be cross connected or muddled up.
A restricted earth-neutral system is a type of electrical system where the neutral conductor is not directly connected to earth ground. Instead, it is connected through a specific impedance. This system is designed to limit the current flow in case of a ground fault to provide a safer operation in certain environments.
If you connected neutral and earth (ground) to each lead in an LED and it glowed then this would be evidence of a ground fault.
Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, the neutral is connected to a system ground in the main distribution panel.

Neutral-earthing reactors or Neutral grounding reactors are connected between the neutral of a power system and earth to limit the line-to-earth current to a desired value under system earth fault conditions.
There is no such thing as a 'neutral phase'. 'Live' or 'hot' conductors are called 'lines', whereas the neutralconductor is at approximately earth (ground) potential.So, a toaster would be connected between a line and a neutral conductor.
There are situations where the secondary of a transformer is not grounded and the neutral is not connected to the neutral of the primary. This can cause a potential shock hazard so the secondary side needs to be protected.
Earth is neutral, but only at the distribution panel and upstream from it. Downstream of the distribution panel, earth and neutral shall not interchange or cross connect their connections or their roles - earth is protective ground - and neutral the current carrying return conductor.
Sometimes the neutral is used instead of the ground/earth but it never should be. Using it that way is a violation of code and a demonstration of the laziness and irresponsibility of the person doing the wiring.
See related link. The neutral wire provides the electric current a return path back to the electrical generation system. It is connected to earth ground, and should have no electric potential in relation to earth ground.
In a three phase system, connected wye, neutral is the common return, and it is grounded. In a delta connection, there is no neutral.
