Theme of connecting a chandelier to two-button switch The owner of the apartment is especially concerned after purchasing a new lamp, because the beauty of the product does not change the connection method. All the standards that you need to know to install a chandelier depend entirely on its design. Learning to connect simple lamps, you can easily understand how to connect a chandelier with a remote control. According to the rules, control settings occur after the lamp is connected.
Electricity with a voltage of 220 volts is dangerous to human life. If knowledge in the field of electrical engineering is not enough, then it is advisable to invite a specialist certified to work with electrical networks to make the connection.
If you need to make the connection yourself, then before starting installation you need to find out the parameters that will help you avoid gross mistakes. Except detailed instructions, it is worth studying the video where the installation of the chandelier is carried out by an experienced craftsman.
Basic parameters
First of all, it is worth determining what type of lighting the chandelier has, it depends on the lighting element. Modern lamps use:
- incandescent lamps:
- fluorescent lamps;
- LEDs.
Based on the number of wires, all chandeliers are divided into several types:
- lamp with two wires;
- chandelier with three wires;
- lighting fixture with four wires;
- chandelier with remote control.
In addition, it is important to determine the number of wires running between the switch and the chandelier. In residential premises there are 2, 3 or 4 wires in the breaker box.
Installing a chandelier on the ceiling
Before installation, you need to assess the degree of novelty of the wiring. Often no one pays attention to the electrical wiring in the house until it is time to install a new chandelier. And only when old lamp removed, it becomes clear that along with the new chandelier the wiring will have to be changed.
Wiring
Let's start with the electrical wiring, since its type, material of manufacture, and the number of cores in the cable determine how quickly and competently it is possible to make the connection. In old houses, 2 wires of the same color were laid between the switch and the chandelier. There were no problems connecting to such a network.
IN modern houses use 3-4 wires of different colors. In order not to get confused with the color coding of the wiring, let's look at their purpose by color:
- yellow-green color – grounding wire: used to ground the chandelier; some manufacturers use pure yellow or green for such wires;
- wire blue– zero;
- black, white, red, gray, brown, orange, purple, pink, turquoise - phase wire.
Chandelier with 2 wires
Let's consider the first option - when there are 2 wires between the switch and the chandelier. In this case, it will not be possible to alternately connect one or 2 lamps, because the number of wires is designed for direct connection of the chandelier to the network without any options. In this situation, you may not want to use a multi-key device. If there is no need to change it to a single-key one, you can leave everything as is and install a chandelier. The general installation diagram does not differ from the principle of connecting a chandelier with one arm.
Connection diagram for a chandelier with 2 lamps and 2 wires to a switch with 2 keys
The 2-wire wiring diagram can be found in older homes when a third wire was not yet used to control light levels. Today, all new residential buildings use three wires.
Chandeliers that use 2 lamps without the ability to switch them on alternately are currently very rarely produced by industry. Therefore, this lighting installation option arises if you need to swap lamps in an old house. If such a chandelier is offered in a store, then you need to think about whether this purchase is advisable or not. It may be better to choose a model where the lighting is adjustable.
Let's move on to the installation itself. First we make the connection on the chandelier.
The steps are as follows:
- Using the automatic switch, turn off the lighting in the selected room.
- We strip the wires by 2-3 mm, that is, remove the insulation from it.
- We route the wires in different sides so that their ends do not touch.
- Remove your hands from the wires and connect the voltage.
- Now we touch the indicator screwdriver to the wire, while simultaneously holding one finger on the metal part of the handle.
- If the indicator light comes on, then we have a phase; if not, it means zero.
- Now you need to remember the location of the wires and turn off the current in the room.
- In order not to forget where each wire is located, it is worth making a mark with a marker. Usually the first phase is designated “1”, and the zero phase is designated “0”.
- Connect the neutral wire on the chandelier with the blue wire, and the phase wire on the chandelier.
- Insulate the connection points.
Let's move on to the switch. Now you need:
- Connect the phase wire located between the switch and the distribution box with its common contact.
- Connect the phase wire of the switch coming from the chandelier with one of the normally open contacts to the switch.
- Second contact in in this case may not be used. Place the frame with the switch in place.
- Turn on the voltage.
- Check functionality.
This completes the work on installing the chandelier. You can see detailed master classes on videos, of which there are many on the Internet.
When testing and determining the phase in wires, under no circumstances should you touch the exposed part of the wire with your hands, connect the wires together, or touch the screwdriver in the working part. All these actions can lead to electric shock, and the voltage in the network is life-threatening. For the same reason, you cannot start connecting wires until you are completely sure that the voltage is turned off.
According to safety regulations, only the phase conductor passes through the switch, because the neutral conductor does not participate in breaking the circuit.
Chandelier with 3 wires
Let's consider the second option - connecting a chandelier with three wires to a switch with two keys. There are 3 wires from the switch to the chandelier. This connection method is the most common.
Connection diagram with three wires
The connection is made as follows:
- Identify the phase wire using an indicator screwdriver and mark it.
- Disconnect the network.
- Connect the blue neutral wire on the chandelier with neutral wire electrical wiring. Insulate.
- Twist the remaining two wires from the lamp and 2 wires from the panel respectively in pairs, collecting one wire from the chandelier and the distribution panel into each twist.
Now let's move on to the switch:
- Turn on the voltage and find the phase wire coming from the distribution box to the switch. For this we also use an indicator screwdriver.
- We de-energize the room.
- The phase wire located between the distribution box and the switch is connected to the common contact to the switch.
- We connect the remaining two wires, one to each open contact of the two-key switch.
- Next, you should install the two-key switch in place, turn on the network, and check the operation of the chandelier.
Connection diagram for a five-arm chandelier to a two-key switch
Chandelier with 3 wires and color coding
Let's consider the third option - connecting a chandelier with two lamps and three wires to a two-key switch if the wires are color-coded.
Here you can immediately start by turning off the voltage, then you should connect the blue neutral wire of the chandelier to the blue wire of the electrical wiring. Connect the remaining two wires according to color. There is a phase wire on the switch (see color coding above) connect to the common contact. Connect the remaining two wires to the remaining contacts of the switch. Put everything in place, turn on the voltage, check.
In any of the connection options, we must not forget about the insulation of the wire. Exposed parts different wires Under no circumstances should they come into contact with each other. Moreover, after installing the chandelier, there simply should not be any exposed parts of the wiring left; all places where twists must be reliably protected. The easiest way to do this is to use polyethylene terminal blocks.
The need for wire insulation
The connection of the wires with a terminal block occurs through a brass sleeve with 2 screws located inside. Wires are placed and twisted into such a terminal block on both sides. At the same time, all bare parts remain insulated, and for twisting, which means there is no need to strip a large surface of the wire.
The connection is made in the same way if there are three wires coming from each horn of the lamp. Here all the blue wires are twisted together, and the remaining ones are distributed as convenient. The connection diagram is clearly visible in Figure 4.
Connection diagram: 3 wires from each horn
Electrical wiring for a chandelier with 4 wires
The fourth option is a chandelier with two lamps and four wires, wiring with four wires. We do everything as in the previous paragraph. In addition to the above steps, you need to connect the yellow-green wire of the chandelier with the corresponding electrical wiring wire. The same applies to the switch.
Lamp with remote control
Usually they ask a lot of questions about how to connect a chandelier with a remote control, because such lamps are often used in apartments. A chandelier with a control panel is connected to the wires as usual. Therefore, first you need to connect the wires in the chandelier with the wiring wires, choosing one of the above options.
It doesn't matter which switch is installed. To control a chandelier with a remote control, the chandelier must always be energized. Therefore, switches are not used together with the control panel.
You can connect the wires between the junction box and the switch directly, or you can leave the keys as is. But then you will have to constantly use the switch to supply voltage and only then take the control panel or keep the switch on all the time.
Sometimes together with the control panel in included fan. For separate use of the chandelier and fan, different switch keys are used. The control and wiring diagram will be like this.
Wiring diagram for chandelier with fan
Connection. Video
The video below will tell you how to connect the chandelier to the switch yourself and what you will need for this.
Thus, to install a chandelier with 3 arms, the same algorithm is used. First, the purpose of each wire is determined, then the premises are de-energized, the lighting device is connected and the switch is installed. All these operations are carried out with strict adherence to safety precautions.
A chandelier is one of the main lighting devices that all Russians install today. It can be connected to one or several switches. How is the chandelier connected to double switch, what is used for this and what safety precautions are observed? More on this later.
To connect the lamp to double type switch, you must strictly follow the rules and observe safety precautions. It is not necessary to study the documentation, which is intended for professional electricians. You just need to know that all tools for performing electrical work must be well insulated. Work should only be carried out on a de-energized network.
Tools for work
To perform the work, you need to take a straight and Phillips screwdriver, a side cutter, pliers, sharp knife, a digital or dial gauge, an indicator screwdriver and insulating tape.
Pay attention! A knife is needed to insulate a single-core cable element, a side cutter or pliers. An indicator screwdriver is needed to detect the phase.
Conductor marking
To make dialing easier and eliminate errors, you need to use colored insulating cable marking. The generally accepted standard is to mark the conductor element with a green stripe. In no form should you use a source that is green in color to connect devices. This source is used to ground the contact.
A zero or neutral source has blue or light blue conductors. Charged conductor elements have different colors. Problems occur when working with wiring that operates on a network long time. Sometimes the conductor insulation was the same in the conductors; for this reason, it is necessary to carry out testing before starting work.
Conductor marking scheme
Ringing wires
The first step is to check the correct connection. A screwdriver with an indicator shows the charge on some source when the switch is not working. If it is not possible to search for a charge, this means that the switch is not connected correctly or there is a problem in part of the distribution board.
Connection diagram for a two-key type switch
Several elements can come from the ceiling covering, one of which is phase, and the other is zero. All lamps can be connected using this electrical diagram. If three cables come from it, then the first and next are phase, and the third is zero. Using this diagram, you can distribute the connection of lamps in a chandelier. There is a moment when three elements emerge from the ceiling covering, but there is no way to distribute the switching on of the chandelier. The third has a yellow-green color and is considered zero.
Connection diagram to a three-key switch
To connect a source to a switch that has two keys, you need to understand where of the two or three wires of a chandelier or five-arm switch is the uncharged conductor and where is the charged conductor. To determine common wire nickname, you don’t need a lot of knowledge, it has a different color from others. This means that the other two have several lighting sections. Then the zero is connected to a common conductor, and each section, which has different conductor phases, goes through a two-key type of switch.
Connection diagram for five-arm type
Safety precautions
When making the connection, it is worth familiarizing yourself with simple safety precautions on how to connect a chandelier with 5 lamps. According to it, you should not touch exposed cables located on the ceiling. When connecting the chandelier to the wiring, you must turn off the input circuit breakers of the smoke shield. Next, careful insulation of exposed wires and careful study of the device instructions are required.
Important! It’s also worth figuring out how to safely connect a chandelier to 2 switches. It is necessary to exclude children from access to the place of work. In the event of an electric shock, you must immediately turn off the network. It is advisable to work with a partner.
Carrying out work with rubber gloves as a guarantee of safety when connecting lighting equipment
As a result, to connect a chandelier to a double switch, you should prepare necessary tools, look at the markings of the wires and find the ones you need using a voltmeter and ringer. At the same time, it is important to follow safety precautions and carefully study such an element as electrical diagram connecting a chandelier to two switches or several switches.
What is a chandelier? This is modern ceiling lamp with several lamps removed on equal distance from each other. Main task chandeliers provide even, shadow-free lighting throughout the room. Incandescent, LED or fluorescent light sources can be used as light sources. Installing a chandelier is the final part of interior design. Its installation is not as difficult as it might seem at first glance. Minimum electrical skills and a standard set of simple tools are required. To make the installation simple and safe, you can follow the following instructions.
Preparation: continuity testing and phase determination on the ceiling
First you need to decide how many wires are on the ceiling and what they are needed for. Two protruding wires mean that all the lamps will turn on at the same time, three or more allow you to combine them with the order in which they turn on. An experienced electrician can figure this out without difficulty, but it will be difficult for beginners to figure out where the phase and zero are, and what to do with grounding.
It is found only in newly built houses or in premises where repairs have been made taking into account all the requirements for the installation of electrical wiring. It has a yellow-green sheath and connects to a wire of the same color on the lamp. Older houses may not have it. If there is no place for grounding in the chandelier connector, the wire must be insulated to prevent a short circuit.
We are looking for phases and zero.
The remaining wires can be of any color - red, black, white, and the color of the wire does not necessarily correspond to “phase” or “zero”. For precise definition where which wire ends need to be tested with a special tester or an indicator screwdriver - a device with a built-in LED that indicates the presence of voltage. The test is carried out with the network turned on and the position wall switch"ON". We touch the bare ends of the wires one by one and see the result. The phase will light up with a light on the indicator screwdriver, and the multimeter will show a voltage value of 220 V. It should be noted that the tester will only show the voltage between zero and phase. For a switch with one key, it’s even simpler - two wires on the ceiling, one of them is zero, and the second is phase. Before starting work on connecting the lamp, it is necessary to de-energize the wires; it is advisable to do this by turning off the switch on the meter.
The simplest and most common option is two wires on the ceiling and two wires on the chandelier, and a single-key switch installed on the wall. We just connect the ends together. It is advisable to connect in such a way that the neutral wire goes directly to the chandelier, and the phase is opened by a switch. For installation, you can use special blocks or twisting followed by insulation.
With two phases and a two-gang switch, the following options are possible. One phase is isolated, the second is connected to the chandelier. In this case, one key remains unused. The phases are interconnected and connected to the chandelier wire. Then the lamp will be turned on using any key.
Connect 2 or more carob chandelier always on the same principle. From each lamp there are two multi-colored wires, we collect them all and divide them into three groups - two phases and zero. We twist all the wires of the same color together. This will be zero, according to the standard the wires should be blue, but if another is used, it’s okay. We divide the remaining wires in any form into two groups, thus obtaining circuits for switching on lamps 1+3, 2+2, 2+3. We twist the wires together and then connect them to the corresponding terminals on the ceiling.
Connecting a chandelier to a single switch
What to do if there are two wires in the ceiling, and 3 or more in the lamp. In this connection diagram, wires of the same color are grouped. One twist will be connected to the neutral wire, the second to the phase. When turned on, all lamps in the chandelier will light up simultaneously.
Rules for connecting wires
Jokes with electricity are bad, so we do all the work according to the rules. It is not enough to simply clamp a twist of several wires into a terminal or wrap it with electrical tape. It is necessary to solder all such connections, after which it will become more durable, the contact will be better, and it will heat up less. The next step is to connect the chandelier wires to the wires coming from the switch. The use of twisting is unacceptable, so terminal boxes are used. If they are not included in the kit, you can purchase them at any hardware store. When a thick twist does not fit into the clamp hole, you can try soldering a copper contact to it required thickness, but not less than 0.5 mm2 in cross section. Or buy a terminal box larger size, if space in the lamp allows. Then the chandelier is raised to the ceiling, the zero and phase wires are finally connected, all the screws are pulled through, after which it is finally fixed in its place.
Connecting a Chinese chandelier
Chandeliers from the Middle Kingdom are very widely represented on the market. Thanks to the low price and huge selection, they are popular among the population, but difficulties arise with the electric filling. It is recommended to carry out preliminary tests before installing it and connecting it to the network. Let's start with a visual inspection: sloppy connections, thin wires, a weak layer of insulation on them should already alert you. To check the quality of the insulation, you can collect all the wires together and try to short them to the housing through a tester. The device should not give any readings. If this is not the case, then the chandelier must be disassembled and the cause eliminated. Then the contact in each horn is checked separately. To do this, the circuit running from the cartridge to the end of the wire is called. At this stage, it is possible to calculate the wire coming from the central contact in the cartridge for its subsequent attachment to the phase, as required by the standard and safety standards.
Connecting a halogen chandelier (with and without remote control)
Operating principle halogen lamps built on the operation of an incandescent filament in a filler gas with special additives (bromine, iodine). Thanks to this it is possible to reduce overall size lamps and voltage up to 12 or 24 V. For this purpose, a step-down transformer is installed in each lamp of this type. Usually the entire circuit is already assembled and ready for use, two wires remain free, which are connected to zero and phase in random order. If the chandelier is equipped with a remote control, then the control unit is also connected to the transformer. The connection in this case remains the same. Do not confuse the connection wires with the antenna, which receives the signal from the remote control.
From this article you will learn what cross-section of wires is needed to connect to a chandelier, how to ring and determine the phases on the ceiling: we are looking for a grounding wire, we are looking for phases and zero, the designation of the chandelier wires.
How to connect a chandelier in a simple way, rules for connecting wires, connecting a 2,3,4,5, 6 chandelier to a single and double switch and many other questions.
Design features of the chandelier
Chandeliers are most often used as lighting devices in residential premises - multi-lamp lamps designed for installation on the ceiling.
A chandelier is a structure that connects several lighting elements - light bulbs, which allows you to provide the room with good lighting.
If you use a regular light bulb in a room, then to ensure proper lighting you will need to install a powerful lighting element, and even then, if the room is large, it will not be enough.
But such light is not always needed, so more the best option is the use of several lamps.
But if you use conventional light bulbs, you will have to lay your own wire to power each of them or make a branch from the junction box.
But if you install a chandelier, the design of which involves installing several light bulbs, then the complexity of the connection will be the same as for one or more light bulbs.
But at the same time, all lighting elements included in the design will be powered, and from one wire.
And all because the wiring branching occurs at the entrance to the chandelier, and not in distribution box.
Well, you shouldn’t discount the aesthetic side of the issue. A lonely light bulb hanging on the ceiling looks dull, or maybe a beautiful chandelier.
To get good lighting in a room with a perfect combination lighting fixture With the interior, it is not enough just to purchase a suitable chandelier, you also need to hang it and connect it correctly.
What is taken into account before carrying out work?
Let's immediately define several key points that should definitely be taken into account:
![](https://i1.wp.com/elektrikexpert.ru/wp-content/uploads/2017/01/0-2-1-600x410.jpg)
And one more thing - it’s one thing to simply remove the old lighting device and connect a new one in its place, and quite another thing to completely create a lighting power line, including from the distribution board, installation of switches, junction boxes and lighting devices, and then connecting them into one network.
Go deeper into the specifics self-installation We will not discuss the power supply branches of the chandelier, since we are more interested only in how to connect the lighting elements, although some points regarding wiring will be touched upon.
Useful information
Let us immediately point out some features that can help:
- Breaking the circuit with a switch is carried out only through the phase line, and the neutral conductor and grounding conductor (if any) go directly to the consumer;
- For each branch, its own phase wire is laid at the output of their switch (It is separated in the switch itself. single-key switch there is one phase conductor at the output, a two-key one has two, and a three-key one has three). This affects the wire used leading from the switch;
- On the terminal blocks of the chandeliers you can find the designation of the terminals, which makes the connection easier (the marking “L” indicates that the terminal is phase, “N” is neutral, “PE” is grounding).
Now directly, how to connect the chandelier to the switch.
Let's assume that the line is made in advance, the switch is in place, and 2 or 3 wires stick out from the ceiling (with the third wire being “ground”).
In general, the connection diagram is the simplest - “one-key switch - 1 lighting fixture.”
If the chandelier is armless (with 1 lamp), then the connection method does not differ at all from powering a simple light bulb.
It also greatly simplifies connecting a chandelier to one or more light bulbs.
Single-key switch – 1 chandelier
Before starting work, you should determine which wire is which. It would be good if modern wiring with color differences between the cores was used. On initial stage I'm only interested in the "ground".
If the electricians did not mess anything up, the ground wire will have a yellow-green braid.
But you will have to figure out the phase and zero yourself and for this you will only need an indicator screwdriver, but all precautions should be taken, since the test is done in live wiring.
Therefore, before applying voltage, you should make sure that the ends of the wires are separated in different directions and do not touch each other.
And only after this can voltage be applied (you also need to turn the switch to the “on” position).
After we touch the ends of the wiring with the tip of the indicator screwdriver, the indicator light that lights up when touched will indicate that the core is phase, which means the second one is zero.
If there are three wires at the output, and it is not clear which of them is zero and ground, you can use a test light to determine it (we connect a two-wire wire to a regular 220 lamp through a socket). Then we identify the phase with an indicator screwdriver.
If the lamp lights up after applying voltage, then the second wire will be zero (if it doesn’t light up, the “ground” is connected to the control). For reliability, the wires should be swapped.
After determining where each wire is, all that remains is to connect them to the corresponding terminals of the chandelier terminal block, and then secure it to the ceiling hook. In general, everything is as simple as shelling pears.
The diagram for connecting the chandelier to two terminals is as follows:
If the circuit is three-wire, then the connection is made like this:
Now let’s assume that the chandelier is a two-arm chandelier and you need to connect it to a single-key switch.
Each horn is a branch and two wires must come from it (phase and zero), but the “ground” is connected to the body, so it does not go to the branches.
Let's assume that there are blue and brown wires coming from each horn.
To connect the chandelier, you need to separate the wires of the horns by color and twist them together (the blue ones are separate from the brown ones).
Then we connect them to the power line, and it does not matter what color the wires will be phase and neutral.
For example, we connect the brown wires through the block to the phase conductor, and the blue wire to the zero.
Then we isolate everything and check its functionality. Here we note that with such a connection, no matter how many bulbs there are in the chandelier, they will all light up when turned on.
It happens that the third wire in a chandelier or wiring is superfluous (ground is not provided in the lighting fixture or power line).
In the case of a chandelier, we simply ignore this conclusion (this will not affect the performance in any way), but the grounding conductor of the wiring will need to be insulated.
Overall this is general scheme connecting the chandelier and it is identical for everyone, but there are some nuances that will be indicated below.
A little about wiring connections. To do this, you can use either terminal blocks or conventional twisting followed by insulation with protective caps.
Each connection method has its own advantages and disadvantages.
Terminals are more convenient for installation, but it is not always possible to install it.
The twist is more compact in size, but it is not always possible to twist the wires well.
Two-button switch - chandelier
Now let's talk about how to connect a chandelier to a two-key switch.
Since the number of lamps and their division into groups can be very different, we will consider several options:
![](https://i1.wp.com/elektrikexpert.ru/wp-content/uploads/2017/01/4-1-600x450.jpg)
One switch – several chandeliers
Now let's look at how to connect several chandeliers to one switch. Here you will also have to consider the features of the power line.
For example, let’s take a single-key switch that will power three chandeliers at once.
The lighting line diagram with this switch is as follows: phase and zero go from the switchboard to the distribution box.
A wire goes into it from the phase conductor to the switch, and returns to it again.
As a result, in the box we have a zero and a phase (with a switch included in the circuit), to which we can connect the wiring leading to the consumer.
Therefore, in order to connect three chandeliers to this switch at once, it is enough to throw one common line and insert the phase and neutral wires of the lighting devices into it.
Moreover, connecting each chandelier to common line It’s better to do it in junction boxes (they need to be installed additionally). And then, in the chandelier itself, divide it into horns (branches).
Connecting a chandelier with additional equipment
Now about connecting the chandelier in which the fan is mounted. This lighting device does not require anything special to connect, since the fan is the same consumer as a regular light bulb (that is, the circuit is the same as that of a two-arm chandelier).
It should be connected to a two-key switch so that you can turn off the light or fan if necessary.
Also, when connecting such a chandelier, you should read the instructions, which should indicate which of the wires going to power the fan is phase and which is neutral, and use this information when connecting.
The same applies to chandeliers that have remote control using the remote control.
Inside such a device there will be a special executive unit with a controller that receives signals from the remote control.
So, this unit requires power, and it works on the same principle as a light bulb.
But in the chandeliers with LED lamps, lighting elements operate from a 12V network with direct current. And for this purpose, the design of the lighting device contains a step-down transformer, which has phase and neutral terminals.
Connecting this chandelier is as easy as connecting a regular light bulb.
Sometimes there is a need to install a combination switch to power the chandelier, combined with an outlet.
And here the whole peculiarity lies precisely in connecting the switch itself, and not the lighting device.
Since there is an outlet, in order for it to function, both phase and zero must be supplied to it.
And if only a phase conductor was routed to a conventional switch, then a neutral conductor will also have to be routed to the combined switch. The connection diagram for such a switch is presented below.
There are times when the part of the supply wiring protruding from the ceiling is not enough to connect the chandelier. In this case, you can simply increase them.
To do this, you can take two segments copper wire cross section of at least 1.5 mm. sq. and connect them to the line terminals using twisting. Then the connection points should be properly insulated.

Safety precautions
When connecting a chandelier, do not forget about safety precautions. All work should be carried out only with de-energized wiring. Moreover, simply disconnecting the line at the switch is not enough; it must be de-energized at the distribution board.
You need to be very careful about the distribution of wiring before connecting.
5 / 5 ( 1 voice )
After purchasing a chandelier, its assembly follows, the complexity of which depends on its design features and type of fastening. If detailed information can help with this handy instructions, then connecting the chandelier will require electrical knowledge. The safety of lighting in the house depends on the correct observance of all conditions.
Preparing for work
Firstly, it is necessary to determine phase, neutral and grounding among the wires, the presence of which is optional. To make them easier to detect, you can use the electrical diagram in the passport document for the chandelier, indicating the purpose of its conductors and the stages of their connection.
Standard color markings:
- Conductor white or brown– phase;
- Blue – zero;
- Yellow-green – grounding.
The connection is made to a wire of the same color on the chandelier. In its absence, the exposed wire is carefully insulated so as not to accidentally short-circuit it.
Before starting work, the switch keys should be switched to the “off” position. The input circuit breaker on the panel should also be in the off state. Preparing wires for testing involves disconnecting them. The lamp is connected with the power turned off. After preparatory work power is supplied to the wires.
Step-by-step instructions for testing wires with a tester:

Connecting correctly
After identifying the electrical wires, you will again need to turn off the power supply to install the lighting fixture. When twisting wires, it is not advisable to use PVC tapes due to its drying out over time and, accordingly, a decrease in its insulating characteristics.
When twisting electrical wires into one group and screwing on a protective cap, they may oxidize over time and heat up. It is recommended to solder such connections, which guarantees normal contact and no overheating.
When connecting electrical wires from a lighting fixture to ceiling electrical wires from a switch, twisting rules are not allowed. This will require the use of terminal boxes. In this case, there may be a problem when a twist of several electrical wires does not fit into the hole. The solution is to solder a copper conductor with a cross-section of 0.5 square meters to the connection. mm. The connection is insulated, and the free end of the conductor 10 cm long is inserted into.
After inserting all the electrical wires from the lighting fixture into the terminal block and tightening the screws, the chandelier is raised under the ceiling. After attaching the chandelier to the terminal block, connect the electrical wires in in the right order: zeros - one opposite the other, phases to phases - arbitrarily.
Chandelier installation
Connection options for the lighting fixture depend on:
- the number of output electrical wires from the lighting device;
- number of output electrical wires from ceiling;
- number of keys on the room switch.
With two wires
Connecting two contacts of a lighting device to two wires:
- Connection of a neutral contact from a chandelier with a neutral wire in the ceiling which comes out of .
- Phase connection, which is a brown or white wire, with a phase in the ceiling leading to the switch.
Connecting two chandelier wires to three contacts:
- Three ceiling contacts - the result of grounding or connection to a two-key switch.
- To determine the common wire, use an indicator screwdriver. When you touch two wires, the indicator lights up - the third wire will be common.
- When the indicator lights up on one wire, it will be common. This test requires both switch keys to be in the operating position.
- The wires are connected using terminal clamps. The conductor is fixed into the clamp and any ceiling outlet.
- Afterwards the connection is made to the terminal pairs of wires from the lighting device.
With three or more wires
Connection from three wires on the chandelier to two ceiling contacts:
- In this case, only 1 option is possible– simultaneous lighting of all lamps.
- All zeros of the lighting device are connected to each other and their connection to the ceiling zero output.
- The phases are connected in the same way.
Connection from three wires on the chandelier to three ceiling contacts:
- This option is for switch with two keys.
- Marking of three ceiling wires: phase – L1; phase - L2; zero – N. The phases are designed to go to the switch keys, and zero – directly to the chandelier.
- Wires from lamps should be distributed into two sections, each of which is connected to only one of the wires to supply phase through it.
- Be sure to connect both sections to zero. Then pressing one of the switch keys will light one group of lamps, pressing the second - another.
Connection from three wires on the chandelier to four ceiling contacts:
- An additional fourth wire can be grounding, which performs a protective function. Its marking is PE.
- If the chandelier has a yellow-green ground pin, it is twisted to the ceiling ground. If it is absent in the chandelier, the ceiling grounding contact is isolated.
Connecting a chandelier to a single-key switch
If it is necessary to connect a multi-arm chandelier via a switch with one key, two options are possible:
- The lighting device is disassembled and assembled for a single-key switch. Then all electrical wires are connected from the central contacts of the device sockets and connected through the terminal block to the phase one coming from the single-key switch.
- The lighting device is already assembled to a two-key switch, then the connection of all electrical wires from the central contacts of the device sockets is carried out in the terminal block to the phase one-key switch.
If there is a single-key switch and two ceiling electrical wires, among which phase and neutral are found. The phases of the lighting device are connected to each other and to the phase of the electrical wiring, and the zeros are similarly connected.
If there is a single-key switch and three contacts, the purpose of the third electrical wire is determined. After turning on the switch, the voltage on all electrical wires is checked. If there is a phase on two electrical wires, it is necessary to replace the switch with a two-button one.
If there is a phase on only one contact and yellow-green insulation on the third, then both phase wiring of the chandelier are connected to the phase contact of the electrical wiring, and the grounding is isolated and removed.
Connecting a chandelier to a two-key switch
The connection of multi-arm chandeliers to such a switch is made according to the same principle. All contacts from the chandelier are divided into 3 groups: 2 phase and 1 neutral. First, all neutral electrical wires are combined and twisted. The remaining ones are randomly divided into 2 groups, which are also carefully twisted. The resulting 2 groups are connected to the ceiling phases.
Following the example of a three-arm chandelier, connection is possible in two ways - with and without grounding. Without using grounding, the basic steps would be:
- Assembly of electrical parts. There are 2 contacts connected to the light bulb socket - 0, connected on the side, and a phase conductor, connected in the center of the socket. The light bulb horns are attached to the concave base of the lighting device, which connects the electrical wires in accordance with the two-key switch.
- Connecting a lighting fixture to a two-key switch, whose keys determine the number of lamps that light when they are pressed. By themselves, the zeros on the side of the cartridge and the phases from its middle have neither 0 nor a positive charge. Zero is supplied not through a switch, but directly. All the zeros from the lamp sockets form the basis of the chandelier in the form of a plexus. The phases are distributed in the luminaire frame into 2 groups. Both groups and the zero plexus are connected in turn to each of the three electrical wires of the central cable running up through the trunk of the chandelier. The phases go to the phases of the electrical wires of the junction box, and zero to zero.
- Connecting electrical wires in a junction box, from which three electrical wires go to the switch, and the same number to the chandelier. The distributor itself is powered by a two-wire electrical wire. The electrical wire that carries positive charge into the distributor, connected to the contact from the switch. And the electrical wire leading from the distributor to the chandelier is connected in the distributor with zero. Groups of phases are connected in turn with electrical wires from the switch.
- Connecting electrical wires in a switch with two keys and three contacts - on the right, left and in the middle. A phase conductor goes to the central one under constant voltage. The rest are connected to phase groups for distribution of light bulbs. Each key closes the central contact and lights the corresponding number of lamps.
When installed with grounding in the distributor, the third protective electrical wire comes out of it and is connected to the metal frame of the lamp.
Connecting chandeliers with remote control
Halogen lamps operate on 12 V or 24 V, which explains the installation of step-down transformers in each of them. The circuit has already been assembled and you just need to install it. Only 2 electrical wires connected to the ceiling contacts are free. The connection is made randomly.
If there is a remote control, in addition to the transformers there is a control unit. Two conductors with ceiling contacts are connected in a similar way. And the antenna in the form of a thin conductor coming from the other side will facilitate communication between the remote control and the control unit. It remains in the same form inside the cap.
The appearance of only one voltage phase is possible between the phase and the working zero. If everything was connected correctly, the common wire of the lamp is connected to 0, a positive charge is supplied through the switch to two contacts.
If there is a connection error, the common electrical wire is connected to the phase, and 0 is supplied through the switch to the remaining wires. The lamp will light, but if you want to replace the bulb, you may get an electric shock when the switch is off.
If it is necessary to simultaneously turn on/off the lamp with two keys on two contacts that come out of the ceiling, it is possible to install a jumper or connect them mutually in the terminal block.
