Summary： According to the current standards in our country

Colors of live wire, neutral wire, and ground wire
According to the current standards in our country, the fire line is brown or red; Neutral wire - blue, grounding wire is yellow green.
Identification of live, neutral, and ground wires
Live wire (marked with the letter "L" in English, meaning live wire, live wire) Neutral wire (marked with the letter "N" Naught wire, meaning neutral wire)
The pattern of the ground wire (marked with the letter "PE") in the electrical appliance is:
The three hole power socket in our home, if constructed properly, has one hole for the live wire, one hole for the neutral wire, and one hole for the ground wire. The ground wire here is collected throughout the building and grounded. This is what is commonly referred to as the ground wire. Most household appliances
The requirement is to have a grounding wire, which means to connect it together with this wire
The importance of correct wiring:
The live wire is charged, while the ground wire and neutral wire are not. There is one live wire and one neutral wire in a household two socket socket. The live wire can be measured with an electric pen, while the neutral wire is not. Only a three socket socket has a ground wire, which should be connected to the outer shell of the electrical appliance to prevent electrical leakage and electric shock injuries.
There are regulations on the wiring positions of each hole in household sockets. If the socket is opened, it can be seen that the point marked with L is the grounding wire, the point marked with N is the neutral wire, and the grounding wire has a special grounding symbol. People who don't understand should never answer randomly（
Especially the position of the ground wire, otherwise it may cause serious consequences.
Why is there an electric shock?
Some people mistakenly believe that the neutral wire is the ground wire. When connecting the grounding and neutral wires of household appliances together, the live wire forms a loop with the neutral wire and also forms a loop with the casing of the household appliance, making the casing live, especially when the neutral wire has been disconnected due to a fault and the power socket is connected
It is more prone to electric shock when the ground is poor
