hello friends
can i say that Ground(earth) and neutral are same ?
if not so, please distinguish them for me
thanks

berkeman said:What is the context of your question? In what country? In what point in the power distribution system? Some places they are connected, and other places they are not.
neduet said:if three phase motor grounded and neutral are also connected so,
my question only one can doing all necessary work.
like safety and all neutral kind of stuff
berkeman said:What country? What voltages? What is the national electrical safety code in your country? In the US, it is the National Electric Code (NEC).
Snoogans said:The neutral acts as a current return path in normal operation whilst the Earth acts as a fault current path in the event a malfunction causes the active conductor to come in contact with a conductive part of equipment (assuming it is bonded to an Earth conductor). It allows a large current to flow and this in turn trips the protective device.
In australia, the only place the neutral and Earth are connected is at the main switch board. We also use 415V, there may be similarities.
In case the neutral wire was wired up wrong. Duh. :tongue: Electrical codes don't always have overwhelming imperative behind them. But they increase safety slightly enough to be worth it. Plus, the electricians unions' get more work for themselves.david90 said:Why is it not the same if you connect the neutral line to the casing instead of the ground wire? Since neutral is connected to ground at the breaker anyway so what's the different?

Ground and neutral are both important components of an electrical system that work to ensure safety and proper functioning. Ground is used to protect against electrical shocks and to provide a path for excess electricity to flow into the ground. Neutral, on the other hand, is used to complete the circuit and carry the current back to the source.
Ground and neutral wires have different functions and are connected to different parts of the electrical system. Ground wires are typically connected to metal components of the system, while neutral wires are connected to the electrical panel and ultimately to the source of electricity.
No, ground and neutral wires serve different purposes and are not interchangeable. Ground wires are specifically designed to handle excess electricity and protect against shocks, while neutral wires are meant to complete the circuit and carry current back to the source.
If a ground wire is not connected properly, it can pose a safety hazard by allowing excess electricity to build up and potentially cause electrical shocks. It can also interfere with the proper functioning of the electrical system, leading to potential damage or malfunction.
Ground wires are typically color-coded with green or bare copper insulation, while neutral wires are usually white or gray. Additionally, ground wires are connected to metal components of the system, while neutral wires are connected to the electrical panel and outlets.
