For a four-wire system, are there three live wires and one neutral wire, or three live wires and one ground wire?

For a four-wire system, are there three live wires and one neutral wire, or three live wires and one ground wire?
It’s best not to touch things in this area if you don’t understand them. Because you need a permit to touch this thing. The neutral wire is also known as the ground wire. Three live wires are correct; this is usually three-phase power supply. It is recommended to check the principles of three-phase alternating current for reference.
If you don’t understand it, you shouldn’t answer randomly either – how can the neutral wire be the same as the ground wire? It can only be said that in some cases they are shared.
Oh, thanks for the advice. It would be best to provide a more detailed description, thank you! :)
How can the neutral wire also be called the ground wire? The neutral wire is denoted by N, and the ground wire is denoted by PE. The neutral wire is the neutral point of the transformer, while the ground wire is connected to the earth. In some cases, they are connected together on the transformer side, while there are two wires at the user end.
It’s still necessary to understand the differences between the IT/TT/TN systems; it can be a lengthy explanation, and more detailed information is available on Baidu~
Three-phase four-wire system: three live wires and one neutral wire; the neutral wire is different from the ground wire.
You’re too kind. I should also mention that some of the information found on Baidu uses terms from old standards or conventions, and those expressions aren’t very accurate. For official information, one should refer to the standards, such as GB 50065.
Thanks. I also just casually referred back to the scene from those days; it’s just a customary way of addressing it. The key point is to \"suggest checking out the principles of three-phase alternating current for reference.\" ”If it is not three-phase AC, it still has many special meanings. Therefore, technical discussions need to be taken seriously; thanks for the correction. :)
