What is the ground wire?(I)

scanning: author: from: time:2022-06-02

The ground wire, also known as the lightning protection wire, refers to the wire used to introduce the current into the ground; when the electrical equipment leaks, the current enters the ground through the ground wire.

The symbol of the ground wire is E (Earth); it can be divided into two types: power supply ground wire and circuit ground wire. According to the current standard in my country, when the third circuit in GB2681 is marked by the color of the wire, it should generally be the phase wire—the phase A is yellow, the phase B is green, and the phase C is red. Neutral wire - light blue, the ground wire is yellow and green, if it is a three-hole socket, the left is the neutral wire, the middle (above) is the ground wire, and the right is the live wire.
