How to wiring the lighting circuit and how to wire the lighting switch

Tools: Small pliers.

Electric pen, adhesive tape.

1. First find the main switch of the power supply at home, and the primary responsibility is to cut off the power to prevent electric shock. Pull down the switch, test whether there is electricity in the written test of electricity, see if the power is off, and start the next step after determining the power off.

2. Then find the wire to be connected, and distinguish the fire zero line, the red one is the fire line, and the blue one is the zero line. You can use the electric test, and the pen light is on one end of the live wire, and the other is the zero line. Remember that the live wire is electrified, don't touch it with your bare hands, it will be electrocuted.

3. The next thing to do is to pinch the thread. Once the thread is found, use small pliers to pinch off the skin of the thread to reveal a long copper wire. Remember that the leaking copper wire should be long, otherwise the wiring is not easy to connect. A total of four heads have to be pinched off the skin to prepare for wiring.

4. When ready, then wire, connect the two wires corresponding to the color of the power supply with the two wires of the lamp head. Don't forget to pinch off the threads of the lamp head. If you buy a lamp head without wires, you can unscrew the cover on the top of the lamp head, two copper screws will leak out, connect the wire to the mouth under the screws, and then tighten the screws.

5. The next step is to fix the terminal with tape, remember to buy insulating tape. Wrap the connected wire with tape a few times, fix it, and pull the tape tighter and tighter, for the sake of safety.

6. After connecting, restore the wire to its original place and turn the electric switch.

Push on the power supply, try to turn on the light switch, if it is on, it means that the wiring is successful, if it is not on, it means that there is an error in one of the above links.

The correct wiring not only ensures the proper operation of the lighting equipment, but also ensures the safety of the home. Here are a few wiring methods to share.

1. Single live wire connection.

Single live wire connection is the most common home lighting line connection. The basic principle is to connect the luminaire to the power supply through a single wire, and realize the lighting function of the luminaire.

The specific steps of the single live wire connection method are as follows:

1.First, determine the number and location of the lamps that need to be connected to electricity, and select the appropriate wires and switches.

2.Introduce the wires from the power source and connect the wires ends to the live wires of each fixture separately.

3.Select a suitable switch installation position and connect the live wire of the switch with the wire.

4.Connect the neutral wire of the switch with the neutral wire at the end of the wire, and connect it to the neutral wire of the power supply.

Second, the double live wire connection.

The double live wire connection is a safer home lighting line connection, and its basic principle is to connect the lamp to the power supply through two wires, while avoiding the potential safety hazards that may exist in the single live wire connection.

The specific steps of the double live wire connection method are as follows:

1.First, determine the number and location of the lamps that need to be connected to electricity, and select the appropriate wires and switches.

2.Introduce two wires from the power source and connect one of the wires to each lamp at the end.

The end of the other wire is connected to the neutral wire of each fixture.

3.Select a suitable switch installation location and wire the two wires separately with the two wires of the switch.

port connection. 4.Connect the neutral wire of the switch to the neutral wire of the power supply, and connect the live wire of the switch to the live wire of the power supply.

3. Multi-way switch connection.

The multi-way switch connection method is a home lighting circuit connection method used to control multiple lamps, and its basic principle is to control different lamps and lanterns through multiple switches to realize the control and adjustment of lamps.

The specific steps of the multi-switch connection method are as follows:

1.First, determine the number and location of the luminaires that need to be controlled, and select the appropriate wires and switches.

2.Introduce the wires from the power source and connect the wires ends to the live wires of each fixture separately.

Above. 3.Select a suitable multi-switch installation location and connect the live wire of the switch to the wire.

4.Connect the live wire of each luminaire to a different switch to realize the realization of each luminaire.

Control. The connection of home lighting lines needs to follow the principles of safety, reliability and stability, and at the same time, it also needs to be flexible according to the actual situation.

The wiring method of the light switch is as follows:

Tools Raw materials: screwdrivers, diagonal pliers, dual control switches, lights, wires, insulating tape.

Method Steps:

1. The dual-control switch is a switch with two contacts (that is, a pair) of normally open and normally closed at the same time. Two dual-control switches are usually used to control a lamp or other electrical appliance.

2. L1 is the input end, L2 is the normally closed output end, and then connect it to the L terminal of one of the double control switches, be careful not to leave too long wires.

3. This one leads to the inside of the lamp called the control line.

4. Connect the control line through the lamp to the L terminal of another dual-control switch.

5. Cross wire the terminals on the two double-control switches. The two contacts of the two single-pole double-throw switches are connected respectively, that is, the contact 1 of the switch 1 is connected with the contact 1 of the switch 2, and the contact 2 of the switch 1 is connected to the contact 2 of the switch 2, and then the knives of the two switches are connected to the two ends of the lamp as the two ends of the whole switch.

6. Schematic diagram of wiring results: experiment with the switch, there is no problem on it, connect the wire, fix the 86 junction box with screws, buckle the panel, and it is strictly forbidden to connect the switch to the zero line and live wire at the same time.

Before installation, ensure that the load and line are in good condition; If there is no blue background light, it means that the line is not connected properly, and the line needs to be checked; If a single switch is invalid, it means that one line is not connected; If the two switches are invalid at the same time, it means that the common line is not connected properly, that is, the neutral live wire is not connected well or the load is open; If the background light is on but does not work when touched, you need to cut off the power supply and power it on again.

How to connect the lamphead wire:

Tools Ingredients: flower thread, lamp head, plug, scissors.

1. First of all, we need to use scissors to cut off the foreskin of the flower thread and leak 1-2 cm of copper wire.

2. Then we use a screwdriver.

Turn on the lamp head, find the two thread posts, and loosen the screws with a screwdriver to expose the two mouths.

3. Then we will pass the flower wire through the hole of the lamp cover, connect it to the hole of the lamp post, and tighten it with a screwdriver.

4. Then we close the lamp cover and twist it tightly, and the lamp head is connected.

When wiring, it should be noted that when facing the socket, that is, when using normally, it should be ensured that the left side is connected to the neutral wire (green or yellow), the right side is connected to the live wire (red), and the upper wire is grounded.

flower thread). Turning the switch backwards, i.e., from the perspective of the above figure, the wiring sequence should be reversed, i.e. the left side is connected to the live wire, and the right side is connected to the neutral wire.

Question 1: How to connect the cable between the street lamp and the street lamp? It's better to keep it. The first is the increase in the cost of the operation, which needs to be the middle head, and the second is the increase in the cost of maintaining the plum. A breakpoint is a maintenance point.

Now it is generally used to wear the cable as a whole, about to leave no less than 700mm from the ground, and then open the middle, take a zero, a fire, a ground, respectively, throw the small head to the street lamp to power supply. Pay attention to do a good job of three matching.

This is safer and more reliable, and it greatly increases the speed of installation. It takes a lot of time to make cable heads.

Question 2: How to connect the street lights in parallel, pull a wire, and then connect them in parallel.

Question 3: How to wire the street lamp The current in the zero line is the vector sum of the three-phase current, not the sum of the standard (number) quantity. In the case of incandescent lamps, the neutral current is 0 when the three-phase load is balanced.

If it is a metal halide lamp, because there is a third harmonic, the third harmonic cannot be offset when the three-phase load is balanced, and the zero line current is not 0, so the zero line cross-section should not be lower than the phase line cross-section.

Question 4: How are the road street lights wired inside 5 points A cable is laid on one side of the road, and all street lights are connected in parallel on this cable with branch wires. The power side of the cable is equipped with a master switch, and each street lamp branch is equipped with a fuse.

Question 5: How to wire the cable of the street lamp Calculate the maximum power, calculate the current to select the air open, the size of the contactor, connect the timer, and connect the power supply.

Question 6: How to connect the street light line on the road Hello, it must be connected in parallel, otherwise one light is broken, and the other lights are not on.

Question 7: How to control the wiring of the street lamp, three wires Each time controller corresponds to an AC contactor, just connect it to the contactor.

Question 8: How to connect the street lamp cable to the maximum power, calculate the current to select the air open, the size of the contactor, connect the timer, and connect the power supply.

Question 9: How to wiring the staircase street lamp is the best? In general, a single-pole double-throw switch can achieve what you say.

I don't know the specifics, but you can go to the place that sells the switch and ask.

Both. One is a single-gang switch, when wiring, [fire in, fire out] controls a lamp. Another kind of multi-connected switch, which is connected in series to control the fire line on and off, can control a lamp in a different place.

Tools Raw materials: SPDT switches, wires, insulating tapes.

Method Steps:

1. The use of dual-control switch circuits is very extensive, this article sets certain conditions to explain, it is impossible to cover everything, we can refer to it by analogy according to their own lamp installation situation. Suppose that the electric light needs to be installed on the staircase between the 1st floor and the 2nd floor, a switch is installed at the entrance of the 1st floor, a switch is installed at the staircase on the 2nd floor, and the power cord interface is installed at the entrance of the 1st floor.

2. The dual-control circuit is not an ordinary single-control switch, but a dual-control switch. Therefore, before installing the line, you must buy a duplex switch, although the single control switch can also realize the function of the dual control line, but it is very troublesome, the cost is high, and the daily operation is inconvenient. The shape of the duplex switch is very different, the principle is the same, the hydropower hardware store has sold, a duplex control of the lamp line needs two duplex switches.

3. In order to prevent potential safety hazards in daily maintenance, it is best to use two-color wire for the cable used in wiring to distinguish between the live wire and the neutral line. Generally, the live wire uses red insulating cables, and the neutral wire uses cables of other colors of insulating skin, which need to be paid attention to when purchasing cables.

4. The switch should be installed on the live line, and cannot be installed casually, otherwise there is a risk of electric shock. Therefore, before installing the line, it is necessary to check the power cord of the house with an electric pen to confirm the live wire and the neutral line.

5. Then route the wiring according to the schematic diagram shown in the figure below.

6. The live wire coming out of the power supply inlet line is connected to the single-pole binding post of the single-pole double-throw switch K1, the double-throw binding post of the K1 and K2 switches is connected with the red wire cable respectively, the single-pole binding post of K2 is connected with a binding post of the electric lamp, and the other binding post of the electric lamp is connected to the neutral line of the power cable.

7. After the wiring is completed, the wire hinge must be sealed with insulated electrical tape to prevent short circuit and electric shock. At this point, the dual-control light line is installed.

This is a two-open dual-control switch, can also be used as a single-control switch, you first determine whether the two are connected to each other, and some switches are connected to each other when the switch is produced, otherwise the two switches must be connected with wires. A wire of the lamp wire is connected to the neutral wire in the wire box, a wire connector is connected to the wiring hole, and there is a wire hole in the junction box.

You are a dual-control switch, if you need to double-open and dual-control, you can wire according to the diagram. If you are a single control, you can just connect one side, that is, the incoming line and the outgoing line.

The wiring diagram of the lighting switch is as follows:

Switch A and B control a bulb respectively, and can meet the requirements that when a switch is turned on and B is not lit, and a light is not lit when a single switch is opened, B is not lit and B is lit.

The most common circuits of electricians include power distribution system wiring diagrams, electrical instrument installation wiring diagrams, lighting control circuit diagrams, motor control circuit diagrams, television, communication circuit diagrams, household appliances circuit diagrams, equipment protection circuit diagrams, and security alarm circuit diagrams.

The role of lighting fixtures is not only limited to lighting, but also the eyes of the home, and more often it plays a decorative role. Therefore, the selection of lighting fixtures is much more complicated, which not only involves safety and power saving, but also involves many factors such as material, type, style and taste. A good lighting may become the soul of decoration at once.

It's very simple, there should be a red line in that box, which is the live wire, connect it to the socket of L, and connect it from this socket to another wire with the L logo, and there should be 2 wires in the box, which are connected to the position of L1.

The wiring diagram of the general lighting switch is shown below:

2] Switch: Switch means on and off, it refers to an electronic component that can make a circuit open, interrupt the current, or make it flow to other circuits. The principle of the switch is that the "closed" of the contact means that the electronic contact is on, allowing current to flow through; "Open" means that the electronic contacts do not turn on to form an open circuit, and no current is allowed to flow through.

Ordinary switches are widely used in South China, North China, Shanghai Jiafeng Electronics, the most common switches are mechanical and electrical equipment operated by people, which have one or several electronic contacts.

How to wire the wall lighting switch.

Dear, hello, I am glad to answer for you the basic installation steps of the lighting line is the live wire, the zero line side by side go straight into the lamp head, the live wire is connected to the fuse box, and the switch into the lamp holder The method is as follows: first disconnect the power supply at home, to connect the live wire and the neutral wire from the air switch, and connect the zero wire directly with the zero wire wiring port of the wire. 2.The fire change line passes through the switch, and it needs to be accessed from the I end of the switch skin, and then led out from the I1 wiring port, how to wire its lighting circuit?

Above the live wire binding post leading to the wire. 3.Finally, close the air switch, turn on the power, and see if the fuel and land connections are in place.

There should be a separate wiring from the live wire to the switch of each lamp, so that the switch can control each lamp. The power live wire is connected to the switch, and the other end of the switch is connected to the light. The neutral wire can be split to the other end of each lamp.
