How to connect the three wires in the socket and how to connect the three wires in the socket row?

The red line is connected to the live wire, the blue line is connected to the change, and the green line is connected to the inner wire.

The socket strip is a kind of socket, which is a multi-hole socket formed by putting multiple sockets together. To put it simply, a power strip socket refers to a multi-hole socket with a power cord and plug that can be moved, which is a common name for a power converter.

The wiring board socket can be used for multiple purposes, saving space, saving lines, simple and practical, and is a necessity of life.

Appliances with metal casings are basically three-wire plugs, which correspond to three-pin sockets. The function of grounding: the plug in the middle of the three-wire plug is connected to the metal shell of the electrical appliance, and when the three-hole socket is inserted, the metal shell is connected to the earth.

l connect to the live wire n connect to the neutral wire and there is also a ground wire.

On both sides is the neutral line of the fire wire, and in the middle is the protective ground wire. Look at the picture.

The plug flushes the socket, the left neutral wire (cold color line), the right live wire (warm color), and the flower wire is grounded.

The terminal (FireWire outlet) is connected to the L terminal of the two-pin socket (FireWire terminal), and the neutral wire is connected to the N terminal of the socket (neutral terminal).

2. The switch is used to control the lamp, the socket is not controlled by the switch, and the wiring method is to connect the live wire to the L terminal of the switch, and the L1 terminal of the switch is connected to the lamp head.

A terminal block is connected, the neutral wire is connected to another terminal block of the lamp head, and the switch forms a circuit with the lamp. Then connect the live wire to the L wiring of the two-prong socket.

Terminals, which connect the neutral wire to the N terminal block of the socket, and the two-prong socket becomes another circuit.

Question: I don't know which one it is.

Can you elaborate on that?

Answer: Hello, the mainland generally uses red to indicate the English abbreviation l l (live) line, that is, the line of fire; Blue represents the n (neutral) line, which is the zero line; The yellow-green color (commonly known as the flower line) indicates the ground line (E line). Normal.

Ask questions like this.

It would be nice to tell me where to pick it up directly, thank you.

First of all, observe the internal structure of the strip, generally the left is the zero line column, and the right side is the live line column. Connect the live wire first, then the neutral wire, and finally the ground wire.

Green ground wire.

Brown line of fire. Blue zero line.

The three wires connected to the socket are generally red, blue, and white. The method of connecting the three wires of the socket: first turn off the connected power (safety first), then connect the red wire of the socket to the live wire, the blue wire to the neutral wire, and the white wire to the ground wire, and then wrap the three wires together and wrap them tightly with adhesive tape.

Finally, test whether the connection is successful.

The three wires connected to the socket are required to be relatively basic electrician common sense, but it is still necessary to pay attention to safety. The three wires connected to the socket are the live wire, the neutral wire and the ground wire, the two wires are the live wire and the neutral wire, the live wire and the neutral wire can be connected respectively, and the ground wire can not be connected. When connecting the three wires of the socket, it must be operated with the power turned off, so as to avoid short circuit caused by wrong connection.

Precautions

The center line is the line drawn from the neutral point of the generator or power transformer, if it is not grounded, it is called the center line, if it is well grounded (the earth is zero potential), the center line at this time is called the zero line. Although the neutral wire and ground wire of civil electricity are both drawn from the same point, their respective functions are separate and cannot be mixed.

For example, the neutral wire and the live wire are the return lines of electricity, they are insulated from the shell of the electrical appliance, and the current flowing in the wire is of the same size, so the wire diameter is the same thickness. The ground wire is connected with the shell of the electrical appliance, and when the electrical appliance is faulty, there is no current in it, and there is generally no current, so the wire diameter is much thinner. The neutral wire and the live wire are circuits that use electricity, so the neutral wire must not be connected to the shell, which will cause people to be electrocuted.

Summary. How to connect the three-wire plug to the two-wire socket 1, first distinguish the zero wire and the live wire in the wire, and mark it with letters, mark the live wire L, mark the zero wire and then disassemble the three-phase plug, wire according to the principle of left zero and right fire, and the zero wire cannot be connected to the connector of the ground wire, which will cause the circuit to be unable to use normally. What are the precautions when wiring the three-hole socket 1. When the three-hole socket is wiring, the power route should be cut off, so that it will be safer when wiring.

If the power supply line is not cut off, there will be an electric shock when wiring. And when connecting the three-pin socket, look at the color of the cable and connect it according to the color. Generally, the zero line is a cold color line, while the live line is a warm color line, and the other color is the ground line.

2. When connecting the three-hole socket, it is necessary to see how stable the cable box is, and cement and sand can be used to fix it. If the cable box is damaged, replace it with a new one.

What should I do with the ground wire when the three wire plugs are connected to the two wire sockets?

The three wires mainly refer to the fire, zero and ground, in the process of wiring, if there are only two wires, as long as the live wire is connected to the live wire, and the zero wire is connected to the zero line, the ground wire can not be connected. If you want to connect the socket, you only need to pay attention to the L-pillar is the live wire, the N-pillar is the neutral wire, the upper one is the ground wire, and the wire can be connected to the L-pillar and N-pillar.

How to connect a three-wire socket to a two-wire socket.

First, use a screwdriver to disassemble the socket housing; Secondly, the wiring coordinates are marked with L (generally red sheath cable connection) live wire; Then, the terminal block nominal n (generally connected by blue sheath cable) is connected to the neutral line, and the terminal block nominal E (generally connected by yellow-green color sheath cable) does not need to be connected; Finally, install the socket shell back.

It's that simple, good guy.

Yes dear. Generally, the plug of the two wires should be left zero and right fire, right?

The socket for household electricity is generally the neutral wire on the left and the live wire on the right.

The wiring method of the triangle socket is as follows:

1. First of all, we need to open the panel of the triangle socket, and then you will see that there are three wiring posts on it, which correspond to different wirings and will have different logos. For example, there is L, which is used to connect the live wire. n stands for the neutral wire, and there is also a ground wire on it.

2. Next, you need to prepare three wires, and peel off the excess wires by 2 to 3 cm to expose the copper core wires inside. The live wire in it is connected with the terminal post of L, and the terminal post of N should be connected with the neutral wire, which is used to ground the wire.

3. Connect to the terminal post, and then pull it by hand to see if there is a problem of poor contact, and then we fix it with screws, and finally cover the panel and tighten it with screws.

The triangle socket is best grounded:

1. The triangle socket is best connected to the ground wire, and some electrical appliances must be connected. For example, the electric water heater or air conditioner at home must be connected to the ground wire, and the leakage protector must be connected. This prevents the risk of electric shock during the thunderstorm season or when there is a short circuit in the circuit.

2. If it enters the ground wire, even if the shell of the electrical appliance is electrified, the human body will not produce high voltage, and the current has been introduced into the earth, which will avoid electrocution and play a protective role.

The middle jack has no angle grounding wire, the left side has an angled hole to connect to the live wire (L), and the right side is connected to the neutral wire (N). If the live wire is connected to the ground wire, the whole water heater will be electrified, which may burn out the water heater and people will be electrocuted when they are in use. Therefore, the ground wire must not be connected incorrectly.

Hope it helps!

The red wire, the blue wire, the neutral wire, and the green grounding wire.

If there is no ground wire, you can not connect it, and if it is a bungalow, you can also bury a ground wire by yourself.

The galvanized flat iron buried in the concrete in the bathroom is grounded, you find an electric pen and a multimeter, use an electric pen to judge the live wire, and then use the multimeter AC gear to measure the voltage between the live wire and the yellow and green two-color wire, there are 220 volts indicating that the ground wire has been connected, if not, the other end of the ground wire has not been grounded. L is connected to the live wire, N is connected to the zero line, and E is connected to the yellow and green two-color wire.

You should be able to connect the zero wire and the live wire, then talk about the ground wire, that is the ground wire with half yellow and half green, your socket is not without the ground wire, connect the ground wire of the gate knife a little longer, and connect it into the socket! Left zero right fire, a grounding wire in the middle will do!

L: live wire, N: neutral wire, ground wire is connected to the wall next to the gate knife.

Take a sample of the quality of Shenzhen Lanwei's socket can be seen!!

Open the junction box and look for the letters L, N, and E next to the terminal post. l - phase wire (live wire), which has a voltage of 220 volts to the ground.; n - neutral line, the voltage to the ground is 0 volts.

e—ground wire, the voltage to the ground is 0 volts. e--ground wire, some electrical equipment needs to be grounded to the shell, so as not to cause harm to the human body due to leakage. Regardless of whether there is an indication or not, make sure that after the wire is connected, the socket is facing the situation shown below (formula:

Left zero and right phase on ground).

Possible colors of the line: fire line - red or yellow or brown; Neutral line – green or yellow or black or blue; Ground - yellow and green.

The sockets on the market have two wires and three wires, so do you know how to connect the three wires in the socket? What should I pay attention to in socket wiring? Follow me to find out!

The left wire is connected to the neutral wire, the right wire is connected to the live wire, and the middle wire is connected to the ground wire. The three wires in the general socket, the red one is the live wire, the blue one is the neutral wire, and the green one is the ground wire, so it can also be connected according to the color, the red wire, the blue zero wire, and the green ground wire. Avoid mixing up when wiring, resulting in accidents during use.

What should I pay attention to in socket wiring?

1. When wiring at home, any metal wire or metal crust must be grounded for protection, and the laid line should be controlled within meters. In addition, when laying wires, the wires can not be buried directly in the cement, and the depth of the wires buried is generally greater than 10 mm, but some cast-in-place concrete floors can use sheathed wires.

2. The neutral wire of the transformer can be directly connected with the neutral wire, but it must form a loop with the live wire, and there will be no voltage drop loss in the process of connecting into a closed loop. However, the requirements for the grounding resistance of the neutral and neutral wires will be a little higher, and the resistance should be controlled within 10 ohms. If the voltage is 100 kV, the ground resistance should be controlled within 4 ohms.

3. The grounding wire and the neutral wire in the general transformer are connected together, but if they are wired separately later, they will still be repeatedly grounded in the distribution box, but the grounding resistance should be controlled within 30 ohms. If the cross-section of the neutral wire and the live wire are the same size, the ground wire cannot be used as the neutral wire when the current is equally large.

Summary: After reading the above, I believe you have a certain understanding of what to pay attention to in socket wiring. If you want to know more about it, please continue to ******, and more exciting content will be presented to you in the future.
