How to connect the two wires of the three phase wire plug row, and how to connect the three wires of

Facing the front of the socket, the upper one is the neutral wire N, and the lower three terminals are A, B, and C three-phase (or U, V, W) from left to right.

If the impedance and properties of the load connected to each of the three-phase circuits are the same, the loads in the three circuits are said to be symmetrical. Under the condition of load symmetry, because the phases between the currents of each phase are 120° different from each other, the sum of the currents flowing through the center line at each moment is zero, and it is possible to remove the center line and use the three-phase three-wire system for power supply.

The three-phase socket has three wires, which are phase, neutral, and ground.

Take a look at the box (if any) first, there should be a ground row in the box, that is, a wiring block with a PE sign (or grounding sign). A three-phase socket should have a wire coming out of it. If there are two wires, then there is no need to think about it, there is no ground wire, no need to connect.

The distinction between the zero line is generally divided by color, the standard is red (or yellow, green) is the phase line, and blue is the zero line. But now in the case of uncertainty, it is still an electric test, and many of the original old buildings do not have very standardized wiring.

The location of the wiring is easier to determine. Facing the socket, the left side is the neutral wire and the right side is the live wire. There is also a sign on the back of the socket, L is the phase wire, N is the neutral line.

<> grounding wire is two-color yellow and green, represented by PE.

The line of fire is sepia, denoted by L.

The zero line is blue or black. The plug and socket have wiring signs corresponding to them, which are represented by n.

Triphasic? Then it should be 4 lines! One of them is ground.

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 connection method of the three plugs and two wires is as follows:

Tools: plugs, screwdrivers.

1. First open the three plugs, and then use a screwdriver to unscrew the screws on the three plugs.

2. Use scissors to cut off a section of the epidermis, not too long, just the right length.

3. Two wires are connected to the two bow joints under the three-hole plug, the zero wire is connected in the lower left corner, and the live wire is connected to the lower right corner. Then put all three plugs on and plug them up.

Wiring precautions

1. No matter what kind of electrical appliances you are wiring, you must first turn off the power switch at home. In this way, the safety of the operator can be ensured when wiring.

2. When wiring, it is necessary to distinguish the live wire from the neutral line and the ground wire. The general activity is denoted by l, while the zero line is denoted by n. You can also distinguish the live wire from the zero wire from the color, generally the red wire is the live wire, the blue is the zero wire, if it is the yellow and green wire, it is the ground wire.

Sometimes the ground wire needs to be connected, but it depends on the situation. After connecting to the ground wire, the safety performance of the electrical appliances in the home can be improved.

Summary. Hello, how to connect the three-phase electric plug-in two-phase electricity is as follows: to connect a live wire and a neutral wire, there is no ground wire when wiring, so we should pay more attention when using, and also do a good job of leakage protection measures.

When wiring, you only need to connect the live wire to the L binding post, and connect the zero wire to the N binding post, you can distinguish it by the face of the wire, like the red SE line is the live wire, and the blue SE line is the zero line, through the line of the face SE can easily distinguish the live wire and the zero line, we should use professional operation tools when wiring.

What are the precautions for wiring 1. We must cut off the power supply circuit when wiring to prevent the risk of electric shock. 2. When we connect the three-hole socket, we must pay attention to whether the color of the wire is uniform, usually the zero color wire is a cold color wire, the live wire is generally a warm color line, and the other line is the ground wire, distinguish these three lines, we can better carry out the wiring work. 3. We must pay attention to the shell when wiring, and compact the wires inside the shell and do not leak on the outside or squeeze the wires into the inside to prevent accidents.

The way to connect the two-phase wire to the three-phase socket is as follows: the two-phase electricity means that there are only two wires, in fact, it can also be connected to the three-phase socket, as long as the live wire is connected at L, and the offline connection is at N, because there are only two wires, then the remaining electric column does not need to be wired. Before wiring, we must distinguish the live wire, the zero line, some people are not clear, so it is easy to have wiring errors, if there is no wiring experience, it is best not to operate by yourself, it is easy to have a short circuit in the wire, and the consequences are more serious.

In fact, we can distinguish by color, the line of fire is red, and the line is blue. If it is a two-phase electricity and wants to be connected to a three-phase socket, generally speaking, there is a live wire, a neutral wire, and no ground wire, so you should be especially careful when using it to prevent accidents caused by leakage of the equipment. The wiring method is also relatively simple, generally speaking, as long as the live wire is connected to the L binding post, and the neutral wire is connected to the N binding post.

There are relevant signs on the socket, as long as it can be clearly distinguished, it can be connected, it is the easiest wiring method, and it is not easy to make mistakes. Before wiring, you can turn off the power at home to ensure our wiring safety. When the two-phase electricity is connected to the three-phase socket, it is mainly necessary to connect a live wire and a neutral wire, and there is no ground wire when wiring, so we should pay more attention when using it, and we should also do a good job of leakage protection measures.

When wiring, you only need to connect the live wire to the L binding post, and connect the neutral wire to the N binding post, you can distinguish it by the color of the wire, like the red wire is the live wire, and the blue line is the zero line, through the color of the line can be easily distinguished between the live wire and the neutral line, we should use professional operating tools when wiring.

How to wire the pro-three-phase and two-phase sockets together is as follows: 1. Before connecting two wires to the three-phase socket, we need to remove the shell of the socket, and we can disassemble the shell wheel of the socket with the help of a screwdriver. 2. Then the terminal block has an L logo for the general red sheath of the cable, and everyone should pay attention to the red wire with an L logo on the outside of the live wire.

3. The blue sheath cable marks that N can be connected to the zero line, the yellow and green ones generally do not need to be connected, this is the virtual ground wire, and finally we connect the two wires and then install the shell of the socket back, and tighten it with a screwdriver. It is important to keep the wire compacted inside the housing of the socket and not exposed to prevent danger. I hope my reply will help you <>

Do you have any other questions?

Single-phase two-hole socket, facing the right hole or upper hole of the socket is connected with the phase wire, and the left hole or lower hole is connected with the neutral wire; Single-phase three-pin socket, the right hole facing the socket is connected with the phase wire, and the left hole is connected with the neutral wire.

The three-phase socket, comprising a base and a metal contact with a terminal fixed thereon and a housing with a jack corresponding to each contact, is characterized in that it is provided with two insertion seats, the corresponding contacts are connected by conductive sheets to form a kind of two complementary insertion seats, and a partition plate is arranged between each jack on the inner side of the housing.

When the three-phase plug is inserted into one plug-in seat, and the phase sequence is found to be inconsistent, the other plug-in seat is inserted, and the phase sequence can be matched, and there is no need to open the plug or equipment to turn the line.

The grounding screw can be left empty, although it can be used, but it does not meet the safety regulations, for safety or make a grounding wire outdoors, connect him to the grounding screw of the socket!

Left zero right fire, the ground wire in the middle. The socket is connected to L to fire, N is connected to zero, E is grounded, if the socket is used for household appliances, there is no reliable grounding, and the grounding wire can not be connected. Unreliable grounding can easily damage electrical appliances when struck by lightning.
