In the case of household switches, in order to be safe and worry free, how do you need to connect th

When we want to wire a household switch, we must understand the situation before we can start to implement it. We must not try it blindly, so that there will be a great hidden danger to our personal safety. Because you have no idea what will happen after you connect a wire, so in order to make us safe and worry-free when wiring, we should master some socket wiring tips in advanceSo now let's take a look at how to connect the L and N wires in the switch!

First of all, we need to know what the L and N lines are, and we also need to know what color they are. In general, the L-wire is the live wire, which has red, yellow, and green wires. The n wire is the neutral wire, and it has a blue wire.

The ground wire is a yellow-green wire. Once we know that, we're ready to wire! <>

Secondly, at this time, you need to connect the L wire of the switch, and then plug one of the wires into the L end of the switch. Then insert the live wire of the power cord into the L port of the switch, and the neutral wire, that is, the N wire, is inserted into the N port of the switch, and then connect to the ground wire.

Finally, insert another wire from the switch into the terminal of the switch, and you're good to go!

The most important point is that before doing these wiring work, you must turn off the main switch of electricity at home to avoid electric shock due to poor operation during the wiring process! In addition, the live wire and the neutral wire should not be reversed, so that the line may be electrified and dangerous.

Finally, you don't have to wire yourself if you don't have to wire it yourselfMoment of truthIt would be better to let the professionals operate it!

The ground wire is generally used for the protection and grounding of electrical equipment (that is, for fear of insulation damage and live shell), so the switch socket is directly connected to L, and if the lamp shell has grounding protection, the protective wire is connected to the connector of the ground wire.

I don't think the owner has to worry about this, the installers are very professional, and they will definitely put safety first.

This problem is still to find some special electricians to connect, if you don't know how to connect casually, it is easy to be hit by electricity.

I don't think it's better to pick it up yourself, but to find a professional to connect.

This needs to be done by professionals, and it is dangerous for individuals not to do it.

This problem must be solved by a professional, and you must not do it yourself

This is still left to a professional electrician, for the safety of your own home.

You can consult a professional, don't blindly connect randomly, and avoid potential safety hazards.

This question suggests that you directly find a professional electrician, and don't blindly study the electricity yourself.

This should be a switch with a socket, L refers to the live wire, L1 refers to the control line passing through the switch, and N is the neutral wire.

If one of the two wires is connected to a live wire and the other is connected to a controlled load such as a lamp, then it can be connected to L and L1.

If one of the two wires is the live wire and the other is the neutral line, then it can not be controlled externally at this time, and the socket is often energized when the live wire is connected to L and the neutral wire is connected to N, and the switch is useless; When the live wire is connected to L1 and the neutral wire is connected to N, the socket is controlled by the switch.

Generally speaking, L is the live line and N is the neutral line. L1 is the live wire after the switch.

L1 is the phase wire wiring pile connected to the live wire, N is the working zero line wiring pile connected to the zero line, the other is the protection zero wiring pile grounding wire, a shift according to the color of the line is divided into the panchromatic line is the live wire and the zero line, the two-color line is the protection zero line, the working zero is the live protection zero is not electrified.

l Enter the live wire of the switch.

L1 switch controls the wire of the first lamp (connected to the spring tab binding post of the first lamp head), L2 switch controls the wire of the second lamp (connected to the spring tab binding post of the first lamp head), l The live wire of the socket.

n Neutral line into the socket.

Ground wire for the inlet socket.

When the three-hole socket is wired: there are generally three wires: live wire, neutral wire and ground wire, the live wire is connected to the L terminal hole, the neutral wire is connected to the n terminal hole, and the ground wire is connected to the ground wire hole.

How to wire a single-open five-pin socket? The old electrician teaches you step by step, practical electrician technology!

Meaning of socket labeling: L--live wire.

connectors; n--Neutral line connection hole; Icon ground - protect the ground wire PE connection hole.

Meaning of switch labeling: L--live wire inlet connection hole; L1--zero line outlet to lamp connection hole 1; L2 -- zero line outlet to lamp connection hole 2.

Switch control lamp, live wire to socket L, neutral wire to N, ground wire to E, from socket L lead wire to switch L1, switch L2 to lamp control line.

If the switch does not need to control external electrical appliances, such as lights, you can connect the live wire to the L hole of the switch, and then lead it from L1 or L2 to the L hole of the socket to connect it into a controllable socket.

Judging from the ** you sent, there is only one interface on the switch, which means that the live wire of the socket is the same as the switch, so it can only control electrical appliances other than the socket. Otherwise, if you want to control the switch of the socket, you should buy a switch socket with two or three interfaces on the switch.

See if you want to pick it up.

Switch, L is connected to the live wire, N is connected to the zero wire, E is connected to the ground wire, the switch controls 1 lamp, it is in L there is a wire to the switch terminal, the other end of the switch is out to the lamp or other electrical appliances, if you do not need to control other electrical appliances, you can use the switch to control the socket, the power inlet line should be connected to the switch first, and then the other end of the line is connected to the socket L

If the switch controls the socket, the live wire is connected to the switch L1, the wiring from the switch L2 to the socket L, the neutral wire is connected to the socket N, and the ground wire is connected to E. If the switch control lamp, the live wire is connected to socket L, the neutral wire is connected to N, and the ground wire is connected to E, from the lead wire of socket L to switch L1, switch L2 is connected to the lamp control wire.

Steps:

1. The wiring method of a five-hole socket, the main terminals are L1, L11, L, PE, N.

2. The switch is considered when designing, as long as the phase wire, neutral wire, and common three wires live wire L zero wire N ground wire PE are connected to the three holes on the socket, and a wire is connected from the socket live wire L to the switch L1. The lamp head has two wires, one from the other terminal hole of the switch (it should be L11) and the other from N of the socket. The two tied together should be connected to the L of the socket, and the separate live wire should be the L11 on the switch.

The yellow wire grounding (PE) is not connected, and the five-hole belt is open and there are 4 terminals: L1 switch live wire incoming line, L2 switch live wire outgoing line, N zero line, GND or three horizontal and one vertical is the ground wire connection, there are two methods:

1) Socket with switch: live wire connection L1, neutral wire connection N, flower wire grounding wire, L2 can be empty; The two wires are a live wire and a neutral wire, and there is no buried ground wire, in this case, the live wire is connected to L1, and the neutral wire can be connected to N (please note that the socket without the ground wire will trip when it encounters a short circuit, and it cannot be protected if it leaks).

2) The socket is often energized, and the switch is a lamp with a loop: the live wire enters L2, the neutral wire is connected to N, the flower wire is connected to the ground wire, and L1 is connected to the fire to the light source (that is, the live wire connected to the lamp).

You this switch.

It is a dual-control switch, that is, to buy two switches installed in two different places, you can control a lamp at the same time, you only need to control a lamp in one place now, then it is a waste of a contact, that is, 2 do not connect any wire, draw a diagram for you, and the other wires can be wired according to the diagram, but you only have two wires now, and only one of the red lines can be used in these two lines, and the other green line can not be used, so you also need to connect two wires from other places, one is the zero line, and one is the grounding wire.

The open five holes in the surface installation are generally connected inside. If it is not connected, press the following connection:

Switch control sockets.

The fire switch connects L2 with the L wire of the socket, L1 enters the fire wire, the neutral wire enters N, and the grounding PE is entered if there is grounding

The switch does not control the connection of the socket

Connect the switch L1 with the L of the socket with a wire, the live wire into the L1 of the switch, the neutral wire into the N of the socket, and the ground into the ground. Switch the L2 outlet cable to the lamp.

Do not connect the socket cable and the light cable in reverse.

If the socket wire is connected to the switch, after the power is sent, as soon as the switch is pressed, it will be short-circuited, and it will be very loud.

Hope it helps.

Have you ever played the experiment of connecting several small light bulbs to the first line in junior high school, in fact, it is very simple that you don't have the direction of the switch that is disconnected as the output line, and the direction of the reception is receiving, I don't know what you mean because the light is controlled by the switch, and the sub-sockets are in a constant energized state without a switch, if so, then you will connect the two wires of the socket to both ends of the receiving direction, and the two wires of the lamp are connected to the output line, so that the socket is not as good as the switch control is often energized, and the bulb is brightly affected by the switch.

If you just want to imitate an electric plug board, you can switch the output line, select one end of the fire wire, the first step to the end of the lamp, and the socket fire wire marked with the fire wire, lined up, the other end of the zero line according to the law. The two ends of the final line can be connected into a loop, and if you want to do a little better, you can use a non-conductive line such as a forest board to order it yourself and make a box.

Too many people read this document.

It's better to buy one yourself for safety, and you're afraid of revealing the electric horse. Be careful with electricity and pay attention to safety.

Five-hole socket wiring, L terminal connection live wire (yellow, red, green three colors are mainstream), N terminal connection zero wire (mainly blue), three-hole plug in the middle of the segment grounding wire. From the live wire terminal to the power cord to the front and back terminal of the switch, the switch has another terminal wiring control light, and it is good.

The problem is not clear enough. From a security point of view, it's also best not to change the power strip, if necessary, you can buy another power strip to use independently.

If you can't tell the zero line of fire, don't take it.

1. A binding post of the live wire access switch, and at the same time, a wire is drawn from this binding post to the L binding post of the socket.

2. Do not connect the N neutral line to the switch, and directly connect to the N terminal of the socket and one end of the lamp.

3. Lead a wire from the other binding post of the switch to the other end of the lamp.

Socket wiring, the live wire must enter the socket's L oh, zero wire into the N sign.

If you can't tell which is the live wire, you can use an electric pen to measure.

The consequence of the reverse connection is that it can be energized at present, but it is very damaging to the electrical appliances. There are also dangers.

For example, even if you turn off the switch on the appliance, if it is reversed, then the appliance is still in a live state, which is very dangerous.

If there are two red wires inside the switch in your home, then you must have a red live wire. Blue is the zero line.

The electric pen test is very simple, separate the two wires, connect the power supply, and use the electric pen to measure which one has electricity, and the two wires cannot be combined.

Theoretically, there is no problem with the live and neutral wires, and the phase reversal can also be used normally.

However, if the switch is used, the live wire should be controlled instead of the neutral wire.

Generally, there is no danger, just remember that the live wire is reversed, and the general circuit is "left zero right fire".

Single control light switch wiring method:

1. Thread the neutral wire directly through the lamp head, and then place the wire on the center point of the switch.

2. Connect the two sides of the light switch with other typical ones.

3. When the line is outgoing, one is connected to the center point of 220V, and the other is connected to the switch.

4. Finally, check whether the switch can work normally after powering on.

Dual-control light switch wiring method:

We first determine the center point of the dual control switch, and the symmetrical Zhuang point is called the left and right.

1. Connect the left and right switches in parallel with two wires, one switch is connected to the live wire, and the other switch is directly connected to the control line.

2. Use a wire to connect directly to the center point, connect the other end to the lamp, and check whether the live wire and the neutral wire are correctly connected between the switches.

3. It is best to test whether the circuit is correct when energized, and then check whether the lamp can achieve dual control.

4. This control method has potential safety hazards, it is easy to trip, and one trip will cause problems in the whole line.

Three-control light switch wiring method:

When installing the three-control light switch, you need to pay attention to figuring out how it works. The three switches in the figure are ordinary switches, but in different positions, and the positions of the live wire and the neutral line are also very clear. In fact, it is only these two switches that are playing a controlling role, and the middle 2 is just a halfway switch, which determines the way of its own operation by judging the state of 1 and 3.

Please refer to the following figure for the specific wiring method:

Precautions: Under the operation mode of neutral point insulation, it should be done:

1) All electrical equipment must be protected to the ground, and the use of protection zero is not allowed;

2) The mechanical strength of the neutral wire should be the same as that of the phase wire, and the neutral wire is not allowed to be disconnected;

3) The neutral current should not exceed 25% of the rated power supply of the transformer secondary coil, and the three-phase load current should not be too different, so as not to affect the balance of the three-phase voltage;

4) To prevent the direct grounding of the neutral wire, the low-voltage switchboard must be equipped with a three-phase insulation monitoring device, so as to find and eliminate the grounding fault in the low-voltage power grid in time;

5) 4 lightning arresters should be installed on the secondary side of the distribution transformer to prevent lightning overvoltage.

Under the operation mode of direct grounding of the neutral point, it should be done:

1) All the metal parts of electrical equipment that are not charged under normal conditions must be protected to zero or grounded;

2) In the same low-voltage distribution system of three-phase four-wire system, protection zero and protection grounding can not be mixed, that is, one part of the protection zero connection, and the other part of the protection grounding, but if the same equipment at the same time use protection zero and protection grounding is allowed, because its safety effect is better;

3) It is required that the neutral wire must be repeatedly grounded, because in the case of the neutral wire is disconnected, the zero connection equipment shell has a voltage of 220 volts to ground, which is absolutely not allowed.
