Wiring diagram for a two-button lamp. Do-it-yourself ceiling chandelier connection. Connecting a chandelier to a two-gang switch

artificial lighting is an indispensable condition, without which no enterprise or enterprise can fully function. domestic premises especially at night time.

In our article, we will try to tell you in detail how to independently assemble, install and connect almost any chandelier, whether it be a simple one with a single lamp, or a complex design for several lamps with a fan or LED backlight.

And thanks to colorful illustrations and videos, even a person who does not have an electrical engineering education can repeat the installation of a chandelier. The main thing is not to forget about safety when working with electricity.

Step-by-step instructions for installing a chandelier with one lamp

Step 1: Marking.

Skip this paragraph if the chandelier will be installed instead of an existing one, with a similar mount. If the chandelier will be installed in a new place, or the old chandelier has a different type of mount, it is necessary to re-mark the new chandelier mount.

You need to find the center of the ceiling. To do this, measure the length of the walls, divide the result in half and lay the resulting size on the ceiling with a cord and a pencil. IN false ceiling a small hole is drilled for the wires. IN stretch ceilings from PVC film, first special limiting plastic rings are glued, and then a hole for the wires is cut with a blade.

Step 2: Installing the ceiling beam.

In the case when the ceiling is made in the form of a complex design structure, in the form of a multi-level plasterboard structure, stretch PVC fabric or decorative hanging plates, which complicates the direct fastening of the chandelier to the surface, it is necessary to take care of the fastening system in advance. Otherwise, a wire break or even a part of the ceiling may be torn off.

If the chandelier is quite massive and its weight is more than 15 kilograms, then to support the chandelier on the ceiling, it is necessary to lay an additional beam behind the decorative ceiling in advance. It could be like wooden beam, and metal structure, the main thing is that it should be placed just at the installation site of the chandelier. You can also use a special metal chain if the distance from the main to decorative ceiling exceeds 1 metre.

Step 3: Installing the junction box.

From the installation site of the future chandelier, the wires are brought out and lowered to the wall, a junction box will be installed here. Also, wires from the mains supply and from the light switch are brought to this box.

Important note! According to safety regulations, the installation of the junction box is carried out no closer than at a distance of 15 centimeters from the ceiling. The wires from the box should come out with a margin of 10 centimeters.

To connect the lighting line, you must use a separate group of wires coming from switchboard, it must be equipped with a residual current circuit breaker.

The wires in the box are connected according to the chandelier connection diagram. The connected wires are insulated with PVC tape and laid in a box so that they do not intersect with each other. The junction box is closed with a lid and screwed on. From above it will be possible to plaster and glue wallpaper.

Step 4: Install the mounting bracket.

Most simple modern chandeliers for one lamp are equipped with a bracket in the form of a bracket. It serves as a supporting fastener and allows you to install a chandelier in a short time. Also, thanks to the two mounting bolts, maintenance of the chandelier becomes much easier than in older designs with unreliable hooks.

After marking the middle of the ceiling, the mounting bracket is applied near the wire outlet. With the help of a pencil, the place for drilling a hole is marked for the future fastening of the bracket to the ceiling. If the chandelier is already equipped with fasteners, then the drill is selected according to the diameter of the dowel. The hole for the dowel should not be located in the place where the wires pass.

Step 5: Connecting the wires and fixing the chandelier.

The wires coming out of the ceiling must be long enough so that when the chandelier is removed, there is access to the junction of them with the wires of the chandelier.

The wires are stripped of insulation and connected using a terminal block according to the diagram. If there is no terminal block included with the chandelier, then the wires are stripped to a distance of 2 centimeters and twisted in pairs, then the junction is soldered with a soldering iron. After that, everything is isolated with insulating tape.

If the chandelier is made of metal and has a screw on the body for connecting a protective earth, do not forget about it. The corresponding wire coming from the junction box is stripped, folded into a ring shape and screwed tightly with a screw.

After all the wires are connected and insulated, you can mount the chandelier. Make sure that the wires do not fall under the mounting bolts, attach the chandelier to the bracket on the ceiling, aligning the mounting holes and bracket screws - tighten the bolts.

How to connect a chandelier with two or three lamps

The procedure for installing a chandelier with two or three lights is not much different from installing a chandelier with one light, which is given above. The exception is the number of power wires. For a simple chandelier with one lamp, you need two power wires and a ground wire, if you are going to connect a chandelier with not one, but with two or three lamps, then you will need three power wires and one ground wire.

Video: How to connect the chandelier yourself

To connect such a chandelier, the wires from the lamp holders must be connected in accordance with the diagram. One wire is taken from each cartridge and connected together - this will be the middle point, it is connected to the neutral supply wire.

If there are two lamps, then each of the remaining wires from the cartridges is connected to the corresponding phase power wire. If the chandelier is designed for three lamps, then the remaining wire from the third cartridge is connected in parallel with the phase wire from the first or second cartridge. The wires are also connected by terminal blocks or by soldering and insulated with electrical tape.

It should also be noted that to turn on such a chandelier, you will need a two-gang switch and, accordingly, three-wire wiring laid to it. In this case, when one key is turned on, one lamp will light up, when the second key is turned on, two other lamps will light up, and when both keys of the switch are turned on, all three lamps will light up.

How to connect a chandelier with 5 lights

If it becomes necessary to connect a chandelier with four or five lamps, this will also not be difficult. The technology is the same as when connecting a chandelier with two or three lamps, the only exception is the number of lamps in groups of phase conductors. The number of groups and lamps in them depends on your imagination and is limited by the number of supply phase wires and groups of keys on the switch.

How to connect a light switch

To enable simple chandeliers with one lamp, a single-gang switch is used, its installation is as simple as possible. When connecting a chandelier, in which the number of lamps is two or more, two and three-gang switches are used.

If the wiring has already been laid, and the number of groups of lamps in the chandelier corresponds to the number of keys on the switch, it is changed to a new one, following the connection diagram.

Wiring diagram for a two-gang switch

If the circuit breaker is installed on new wiring, attention must be paid to the structure of the circuit breaker. In two and three-gang switches there is one common terminal, it is necessary to connect the supply phase wire coming from the junction box to it. And each of the remaining terminals, in accordance with the location of the key and the desire to turn on a certain group of lamps, is connected to the wires going through the box to the chandelier lamps.

It should be noted that the switch must open exactly the phase wire of the power supply! This will protect you when you change a burned-out lamp with the switch off.

How to connect a chandelier

Chandelier with fan

There are models of chandeliers in which two devices are combined: a lighting chandelier and a fan. Such a constructive solution will be a good help on hot summer days. Connecting such a chandelier is not as difficult as it might seem at first glance.

Before connecting, read the passport for the chandelier, the connection diagram and the color designation of the wires will be indicated there, the main thing is not to confuse anything.

Ceiling Fan Diagram

For easier connection, the fan outputs can be figuratively represented as another lamp. You can switch the fan on according to your desire, either together with the lighting, or with a separate switch button.

In the case where the fan is turned on separately from the lighting, you will need a three-wire power line and a two-gang switch. The connection in this case will be identical to connecting a chandelier with two lamps, only there will be a fan instead of the second lamp.

If you plan to turn on the fan at the same time as turning on the lighting, then you need to connect the wires from the fan in parallel with the terminals of the lamp holder.

In some modern models chandeliers there is decorative lighting on multi-colored LED light-emitting diodes. Such chandeliers create a more interesting light, thereby emphasizing the interior of the room.

The connection of such a lamp is carried out strictly according to the scheme, which is given in the passport for this product. The LEDs are designed for low-voltage power, so a step-down LED driver is used in the chandelier kit. The power supply of such an LED driver is designed for a lighting network voltage of 220 volts.

When connecting such a chandelier, you can use the above instructions for connecting a chandelier with a fan, only here instead of the fan wires, the power wires of the LED driver are used.

It is not necessary to call a professional electrician to your house to connect a new chandelier to the switch. One or two keys, it doesn't matter. This is a fairly simple job that can be done qualitatively and independently, while saving money. Most importantly, stick to step by step instructions, listen to advice and clearly follow the recommendations given by experts in the field of electrical installation.

Chandelier connection

Whatever the chandelier, the connection principle for such lighting fixtures practically the same. And it's quite simple. Moreover, it does not matter - you need to connect the chandelier to a single switch or to a double one. Installation, of course, is different, but both are easy.

So, any light bulb is on if two mandatory wires are connected to it:

phase;
and zero.

And the chandelier is the same light bulb, and in order to connect it, one conductor from the junction box must be connected directly to the chandelier, and the second also to it, but with a gap, the role of which is played by the switch. And in no case should a zero conductor be allowed through this switch. Safety precautions strictly prescribe to conduct it exclusively directly - from the junction box to the lamp (chandelier). No breaks!

Before starting the connection activities, you should make sure that the electricians who installed the wiring initially correctly colored the wires:

the working zero conductor must be blue or light blue;
protective zero conductor - yellow-green.

To check whether the conductors were correctly marked by the masters, it is necessary, armed with an indicator screwdriver, to look where zero comes out of the junction box (or directly from the ceiling), and where is the phase.

Everything is simple here: if the indicator sensor lights up when you touch the wire, then this is a phase, no - zero. Before the procedure, the screwdriver indicator can be checked on any live object - in a socket or a floor shield, for example.

Wires can go from the ceiling in different ways:

How to connect a chandelier

Connection of various chandeliers is possible to various switches:

single-key;
and two-key.

Connection via one-button switch

The most simple circuit connecting a chandelier is when a wire pair comes out of a hole in the ceiling. The connection process is then extremely simple: the wires are connected to each other in pairs, and that's it. Even the sequence of such a connection is not important. That is, the blue zero wire in the junction box is directly connected to the zero wire, but already in the chandelier. A Brown the phase-wire from the power source all in the same junction box goes first to the switch, and then to exactly the same phase-wire, but already in the lamp (chandelier).

Connect the wires using screw terminals. You can also twist a wired pair with pliers, but you will definitely need to isolate the ends of the wires using special caps. These are mandatory safety requirements.

But it is better not to use electrical tape (or PVC tape), which many people are used to "winding" wires. It will definitely dry out over time, and, naturally, the quality of the insulation performed will suffer.

In chandeliers of a certain design, there is no provision for pre-combining the lamps, and then the wire pairs come from each of the bulbs.

When the chandelier has more than one lamp, there are no problems with its connection. The zero wires of the chandelier are assembled, connected and then connected to the network zero wire. The same is with the phases, but they are connected from the switch to the phase wire.

The connection process is a twisting of single-color wires. And then the resulting twists are connected to the wires that go along the ceiling to the single-gang switch.

Video instruction for connecting a single-key switch is presented below:

Connection via switch with two buttons

Many today are interested in the variability of the regulation of the degree of illumination different rooms in an apartment or country house. Therefore, the question of how to connect the chandelier to a double switch, which allows you to turn on the chandelier lamps not only at once, but also in stages, can be especially relevant.

Let's start with the fact that almost all wiring in city apartments or country mansions is now carried out using a three-core cable, in which there are wires in multi-colored braids. And three multi-colored wires from a two-gang switch are also suitable for the mounting place of any chandelier. And first you need to determine what the purpose of each of these wires is.

It is clear that one is a zero wire, and it is common to the entire set of lamps. And the other two are phase, passing through different switch keys.

Today, unfortunately, there is no clear color scheme that all electricians would adhere to. Therefore, the wires of different companies are braided differently. So, before connecting the existing wires, you need to clearly find out their purpose. This can be done using a special indicator (or an indicator screwdriver - also good tool). And be sure to turn on the switch keys. Where the indicator detects voltage, there will be a phase, where not - a neutral conductor.

If there is no indicator in the house, the process is slightly, but more complicated. You will have to de-energize the room completely, disassemble the switch. More precisely, it will be enough just to remove the cover from it to see what color and from which key the wire goes directly to the chandelier. The neutral conductor, of course, does not pass through any keys.

In principle, connecting a chandelier through a two-key switch is similar to the process of connecting it through a single-key switch. The only difference is that the phase lamp conductors are divided into 2 sections. And one twist from each lamp group is connected (together) to the zero conductor. The remaining pair of twists is connected (individually) to the remaining pair of wires.

Connecting the chandelier to a double switch gives the user the ability to control the amount of light in the room by lighting the lamps in steps.

A brief video instruction for connecting a two-gang switch is shown below:

Several chandeliers on one switch

This lighting option is also possible for residential and commercial premises. It is ideal where you have to turn on several lights at the same time in one or several rooms at once.

The connection is as follows: chandeliers (or a group of LED / halogen lamps (if halogen, then with the installation of a step-down transformer)) are connected parallel connection. In addition, each of the lamps:

connected to the circuit breaker through a separate junction box;
or placement occurs in a single junction box.

It all depends on which electrical wiring scheme will be chosen.

Connecting one chandelier to two switches at once

In order to put into practice the wiring diagram for connecting a chandelier or a group of halogen (with the installation of an additional step-down transformer) / LED lamps from 2 different switches, you will need special “pass-through” switches that are structurally different from the usual ones. In addition, there are three pins in their wiring diagram:

common output to the phase wire or directly to the chandelier;
a pair of auxiliary contacts for connecting switches to each other.

This option of power distribution must be carefully thought out in advance (and if there is a repair in an apartment or office, then even before the start of repair measures). Otherwise, it will take no more, no less than to lay one more wiring in the room. Well, and make subsequent cosmetic repairs, of course.

Safety precautions when installing chandeliers connected to switches

Those who are going to independently connect the chandelier to any of the above switches in any of the above ways should once again be reminded that installation work installation of fixtures and high-quality connection of switches must be carried out in compliance with safety regulations. And the following rules are binding:

Any electrical activities are carried out only when the corresponding branch of the wiring is completely de-energized (and you don’t have to be content with the “off” position on the switch, it is better to switch the switchboard machines to the appropriate position).
Do not twist copper wires with aluminum wires. It is fraught with fire.
It is necessary to prevent contact of wires that are energized and open for testing.
It is required to carefully monitor the wire markings when you need to connect the chandelier to a single switch, and even more so to a two-gang one. The neutral wire is always marked with the letter "N", the phase with the letter "L".
To determine which of the wires is the phase, and which is zero, should be done using a special indicator screwdriver. And it is necessary to touch the bare ends of the wires strictly alternately.
For the period of testing the wires, electricity is connected, but immediately after the end of the process, it is necessary to de-energize the required installation area again.

The choice of lighting device should be entrusted to the wife. Ladies are much more fond of shopping, looking for goods on sale, they have a better sense of beauty, so for her it will only be a joy. How much money to allocate to the adored wife? It all depends on the model, the materials from which it is made, and other features. When choosing, emphasis is placed on the unity of the design styles of the lamp and other elements of the decor in the room. For example:

MW-LIGHT Bouquet – suspended structure guarantees ease of installation, since this five-arm chandelier can be connected using a conventional three-channel terminal box. All contacts are already grouped together and are output in a single winding with three cables. The cost of the model does not exceed 6,000 rubles - another plus for the wallet. Floral style - ideal for the bedroom, but also suitable for other rooms.
Favorite Lanta- pendant model with advantages similar to the previous design. Looks like crystal, costs much less, ideal for decorating a living room or large halls. The power of all lamps in the aggregate is 200 watts. The price of the product is 13,000 rubles.
Chiaro Versace is a very luxurious piece of furniture (46,000 rubles), has a powerful design, is mounted on a durable ceiling hook. All this allows us to recommend the chandelier to true connoisseurs of beauty, who do not spare money for luxury. Plus: all the wires are hidden inside the barrel of the product, which allows you to regroup pairs of lamps.

All listed models can be purchased in our store, they are always in stock. In case of difficulties with the choice, you can contact a consultant.

How to connect a five-arm chandelier without tools?

Not every home has voltmeters, multimeters, indicator screwdrivers and other equipment for electrical work. In order not to spend money on their purchase, we decided to give you a few useful tips how to do without serious tools and still connect ceiling lamp Right:

An indicator screwdriver is needed to identify the phase and zero. You can find out about the purpose of the wires in other ways: look at technical documentation, from the marking (“L” - phase, “N” - zero) or by color - brown, black or red colors are characteristic of the phase, zero is indicated in blue.
A multimeter is needed to check the correct connection of a 5-light chandelier. An easy way to do the same, but without a device, is to turn on the power supply and press the switch keys.
Instead of pliers, you can use a regular kitchen knife to clean the cable cores. The braid is heated by fire from a lighter, softened and removed. Try not to overheat the wire to avoid loss of its performance.

Everything you need to connect a 5-arm chandelier: a sturdy chair, a knife, electrical tape. Instead of twisting wires, you can use a terminal box, it comes with the lighting equipment itself.

Basic wiring diagrams for a ceiling lamp

We will analyze 4 methods for synchronizing cables:

How to connect a chandelier with 5 horns to a single-gang switch.
Method of synchronizing the cables of the luminaire with the terminals of the two-gang panel.
Connecting equipment from which 10 cores depart.
Installation of a chandelier with three cables.

How to connect a 5-horn chandelier to a single-gang switch?

In this model of the breaker, two or three cables of the main power supply network are provided: phase, ground and zero. In most cases, there is no "land", its use is justified only in industrial buildings. A single-key switch will turn all the lamps on and off at the same time, so there is no point in dividing them into groups. If two cables with a phase come out of the chandelier, they should be wound together and brought into the terminal box. You can use the serial connection method: insert the ends of the cores from different slots, fix them with bolts and close them with an additional common cable with a cross section of 0.25 sq. mm. The final stage in connecting a five-arm chandelier - insulation of an additional wire after connection.

Zero is always a common cable, therefore, only one core is provided for it from the general network and from the chandelier - there will be no connection problems.

Wiring diagram for a chandelier with 5 lamps for a two-gang switch

From the breaker with two buttons, two phase wires and one zero wire depart. Manufacturers of chandeliers with five lights also divide the total number of fixtures into two groups: two and three lights. Therefore, three cables also come out of the trunk of the lighting device: two phases and zero.

This scheme for connecting a chandelier with 5 bulbs is the simplest: connect the phases of the chandelier to the phases of the network and both zeros with a twist or inside the terminal box. When using the latter, do not twist the contacts too tightly - the core may break off, and electrical circuit will break.

How to hook up a chandelier with 5 bulbs and 10 wires?

Here, difficulties arise most often, but this method has one important advantage - you yourself choose which lamps to combine into groups. The neutral wire is always common, so follow these steps:

Hang the chandelier on a hook so that it does not fall and is not suspended.
Find the neutral wire using colors, markings or instructions in the data sheet.
Connect 5 zero cores of the chandelier with pliers or a screwdriver in the terminal box in a consistent way.
Insert one neutral cable into the box on the other side and fix it with fasteners.
Divide the phases into two groups if you have a two-key switch or combine them into one if you have a one-button switch. The number of terminal boxes used depends on the number of groups: it is easier to hide two small ones than one long one.
Connect the phases in the same way. All twists should be isolated with tape.

Important: do not touch the conductive paths even when they are de-energized. Residual voltage will not cause a critical force strike, but it can disable a person for a while.

Wiring diagram for a chandelier with 5 horns and three common cables

The method is similar to the first method. However, here the manufacturer has already distributed the groups of lamps and simplified your task: you don’t have to think about how to connect the wires in a chandelier with 5 horns. After connecting, check the operability of the lighting device. To do this, activate the automatic switchboard and turn on the switch buttons. If you strictly followed our instructions, everything should start working after the first installation attempt.

Dare! We are sure that your work will delight your wife, mother-in-law and other ladies in your environment!

Connecting lighting fixtures seems like a simple task. It would seem that what is so difficult here is to connect two wires coming from the ceiling? However, sometimes an unexpected problem arises before the home master: what to do if there are not two, but three wires in the chandelier? How and where to connect them? Let's try to understand this issue.

Required tool

To properly connect the chandelier you will need:

Indicator screwdriver or voltage indicator;
Multimeter;
pliers;
Terminal block for three terminals;
Insulating tape.

You will also need a stepladder or a stable stand, a marker, a sheet of paper and a passport for the lighting fixture.

Determining the purpose of the wires in the chandelier

The simplest thing is to use the electrical circuit, which can be found in the passport for the lighting device. It usually indicates the purpose of all the wires and the order in which they are connected. According to accepted standards, the color marking of wires should be done as follows:

White or brown wire - phase;
Blue wire - zero;
The yellow-green wire is a protective ground wire.

If there is no documentation for the chandelier, and the color marking of the wires does not clearly indicate their belonging, it is necessary to determine their purpose using a multimeter.

Connecting a double-circuit chandelier to the mains

To properly connect a chandelier with three wires, two of which are phase wires, you need to inspect the switch and the wires coming out of the ceiling. The simplest case is when the switch is two-gang, and three wires come out of the ceiling. You can determine the purpose of these wires as follows:

Take an indicator screwdriver or voltage gauge.
Turn on both keys of the switch.
Alternately touch the voltage indicator to the stripped ends of all three wires. Upon contact with the phase wires, the lamp on the voltage indicator will light up.
Mark the phase wires with a marker.
Turn off the switch. Check all three wires again. The lamp should not light up!
Connect alternately the phase wires of the chandelier to the marked phase wires of the electrical wiring, also connect the neutral wires. The connection is made using a terminal block or twisted using insulating caps or electrical tape.
Check the operation of the chandelier, turning on both keys in turn.

If the switch is single-key and only two wires come out of the ceiling, then it is necessary to check them with the switch turned on with a voltage indicator and find the phase and neutral wires. The phase wires of the chandelier are connected to each other and to the phase wire of the electrical wiring, the neutral wires are also connected. Check the on and off of the chandelier.

If the switch is installed single-key, and there are three wires in the wiring, it is necessary to find out the purpose of the third wire. To do this, turn on the switch and check the presence of voltage on all wires. If the phase is found on two wires, then you need to replace the over-gang switch, and the chandelier can be connected in a three-wire circuit. If the phase is only on one wire, and the third wire has yellow-green insulation, then the connection is made as in the previous case: both phase wires of the chandelier are connected to the phase wire of the electrical wiring, and the ground conductor is insulated and removed.

Connecting a chandelier with a ground wire

If the lighting device has a metal case, it must be grounded. In new apartments, all electrical networks, including lighting, according to the standards, must have a yellow-green grounding conductor. If your network meets this requirement, then to connect the chandelier, it is enough to connect the wires with the appropriate color marking using the terminal block or twisting.

If the networks are old, and the insulation of all wires has the same color, then you should proceed in the following sequence:

Determine the number and purpose of wires coming out of the ceiling. If there are two wires, then turn on the switch and use the voltage indicator to find the phase and zero. The switch is turned off and the wires are connected to the corresponding wires of the chandelier, and the ground wire at the chandelier is insulated.
If there are three wires, then proceed in a similar way. If there are two separate circuits and a two-gang switch in the network, then the phase wires of the wiring are combined and connected to the phase wire of the chandelier, the neutral wires of the wiring and the chandelier are also connected, and the ground wire is isolated.

Safety

Care must be taken when connecting any electrical appliances. All connections and connections must be carried out only when the switch is off after checking the absence of voltage on the wires. Places of twists are isolated using special caps or electrical tape. If you doubt that you can connect a chandelier with three wires correctly, it is better to entrust this matter to professionals.

Chandeliers are most often used as lighting fixtures in residential premises - multi-lamp fixtures designed for ceiling mounting.

A chandelier is a structure that connects several lighting elements - light bulbs, which allows for good lighting in the room.

If you use an ordinary light bulb in the room, then to ensure proper lighting, you will need to install a powerful lighting element, and even then, with significant volumes of the room, it will not be enough.

But such light is not always needed, so more the best option is the use of multiple lamps.

But in the case of using conventional light bulbs to power each of them, you will have to lay your own wire or branch out from the junction box.

But if you install a chandelier, the design of which involves the installation of several light bulbs, then the connection in terms of complexity will be the same as one or more light bulbs.

But at the same time, all the lighting elements included in the design will be powered, and from one wire.

And all because the branching of the wiring occurs at the entrance to the chandelier, and not in the junction box.

Well, do not discount the aesthetic side of the issue. A lone light bulb hanging on the ceiling looks dull, or a beautiful chandelier.

To get good lighting in a room with a perfect combination of a lighting fixture with an interior, it is not enough just to purchase the right chandelier, it still needs to be hung and connected correctly.

Analysis of the contacts of the lighting device

When mounting a lighting kit on a ceiling surface, wires are found both on the ceiling itself and in the device. If the wiring of the room has already been laid, then there can be two, 3 or 4 wiring on the ceiling plane. Regardless of their number, one will be "zero", the rest are phase. Sometimes there is a ground wire.

But this is a rarity and there is a similar conductor either in newly built houses, or after major capital repair work during which the wiring was completely changed. According to existing standards, grounding is painted yellow-green. It connects to exactly the same conductor on the chandelier. If there is no ground in the lighting kit, then the wire on the ceiling should be well insulated and left unused. It is impossible not to isolate it - it can short-circuit.

After grounding is found, you need to deal with the remaining cores and determine where the zero and phase elements are. As a rule, all wiring is painted black, therefore, to recognize which one is which, it is better to ring them.

Calling can be done in two ways:

Indicator screwdriver - in this special device, a red light will light up as soon as voltage is detected. To work with it, first of all, you should set the switch key and the button on the input machine of the shield to the “on” position. Now you can very carefully ring the conductors. Having determined where the “phase” is located, you need to highlight them with color. After ringing, the keys must be moved to the "off" position. If possible, all manipulations for connecting the chandelier should be carried out with the machine turned off on the shield;
Tester (multimeter) - here the switch is set to the "volts" position, then a scale with an indicator of more than 220V is selected. With the available probes, carefully, holding the handles, you need to touch the pairs of conductors. If there are two "phases" in a pair, the tester indicator will not change in any way. If a similar pair is found, then the third wire is most likely zero. Next, the selected pair must be connected to “zero” with the help of a probe, at the same time 220 V should appear on the indicator. Corresponding to the international classification, the neutral conductor is indicated by the letter N, and the phase conductors - L.

If three conductors are displayed on the ceiling sheet, and the switch has 2 keys, then there are two phase wires for each of the keys, and one common neutral core.

Connecting a chandelier with a pair of conductors is as easy as shelling pears: one must be connected to the “phase”, the second to “zero”. It doesn't matter where or which one goes.

In a situation where there are two “phases” on the ceiling sheet, and the switch has a pair of keys, that is, there are several options:

Both phase conductors are twisted, and one from the chandelier is connected to them. In this embodiment, the device will turn off immediately with two keys, but any of them will turn on;
The wire is connected to one of the phase on the ceiling, and the second is insulated. Then only one switch key can work, while the second one will remain idle.

In the case of a three-lamp and other multi-track chandeliers, we have more than two wires. If yellow-green is among them, that is, grounding, then if there is the same on the ceiling, you need to connect them together. Three wires have fixtures with one working bulb.

Since all contacts are defined and labeled, all neutral conductors coming out of a single cartridge are initially combined in the center. In this case, the “phases” remain divided into 2 groups in the form of 1 2. Where there is contact 2, they must be twisted as a single pair. When the power is off, the contacts of the device itself are connected to the ceiling.

The standard situation for connecting a chandelier to a double switch with 4 shades is the presence of the lamp itself, a two-gang switch and three contacts coming out of ceiling. Sometimes, especially in new buildings, there is a fourth contact in the form of ground, which is used if the lighting fixture has one.

You can connect such a device in two ways:

the first, when the contact connection diagram will look like 1 3, that is, either one or three lamps can light up at once;
the second has a scheme in the form of 2 2, when the bulbs will light in pairs. This method is energy-consuming and is most often used when 1 lamp is not enough for full-fledged lighting of the space, but three are many.

When you press a pair of keys at once, all four horns on the chandelier will light up.

To connect a 4-arm chandelier to a double switch, you need to connect the phase contact coming from the network through the distribution panel to the wire that goes to the switch. After that, you can connect it to the input contact, where it always is. The second conductor, which is connected to the key conductor, is taken to the junction box, where it is connected to the contact, which is connected to the device installation area. Here, the contacts of the device and the network must be connected to each other. According to the same scheme, the contacts on the adjacent key are connected.

The difference between these two keys comes down to a different number of "phase" wires connected to the network cores.

The scheme of work on connecting the device, where there are five light bulbs, is quite complicated. This is due to the large number of conductors, each of which must be dealt with. Lamps when working on a two-gang switch contribute to energy savings by working in a suitable mode.

Before starting work, you should determine the common wire coming out of the device. This will be the zero contact, which is marked with colored tape. This must be done so that in the future it will not be confused with other veins. There is a similar contact ceiling surface, while it is also marked with electrical tape of the corresponding color.

Those contacts that, after checking on an indicator screwdriver, showed voltage, are called phase contacts. They are coming out of the ceiling hole, and in each horn.

When all the cores are found and marked, the five-armed chandelier is hung on a hook, and the contacts begin to be connected. First of all, zero, and then phase cores are combined. Light bulbs can be assigned to the switch keys according to the 2 3 or 1 4 scheme. The first option is optimal, in which one key turns on two lamps, and the second the remaining three. Also, all bulbs can work at the same time.

The intensity of the light fluxes in the room depends on the specific type and reduced power of the bulbs used in the lamp.

If you plan to connect a multi-lamp six-arm luminaire, then the wiring must be appropriate, respectively. In this case, the two-button switch model can provide only three operating modes:

two burning lamps;
four lamps;
all 6 bulbs working.

Most of the devices with 6 bulbs already have a properly assembled part of the electrician. If not, then the layman will meet 12 contacts in the lamp (2 for each horn). Six zero cores should be combined in one terminal. The remaining six phase contacts are combined into two terminals in groups (2 4).

On the ceiling, all contacts are also called to highlight "zero" and "phases". Next, it is determined which conductor corresponds to this or that key. To do this, one key is switched to the “off” mode and the presence of electricity is checked. If the indicator shows no current, then the conductor corresponding to the switched off key is selected.

After all the preparations, contacts from the chandelier are connected to each switch key. The zero ceiling core is connected to "zero" in the terminal box of the chandelier, the phase cores are combined with groups of phase contacts of the device.

What is taken into account before work is carried out?

Here are a few key points to keep in mind:

And one more thing - it's one thing to simply remove the old lighting fixture and connect a new one instead, and it's quite another to completely create a lighting power line, including wiring from the switchboard, installing switches, junction boxes and lighting fixtures, and then connecting them to one network.

We will not delve into the features of self-laying the power branch of the chandelier, since we are more interested only in ways to connect lighting elements, although some points regarding wiring will be affected.

Helpful information

Here are some features that might help:

Breaking the circuit with a switch is carried out only along the phase line, and the neutral core and the ground wire (if any) go directly to the consumer;
For each branch, a separate phase wire is laid at the output of their switch (It is separated in the switch itself. A single-key switch has one phase conductor at the output, a two-key switch has two, a three-key switch 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 facilitates the connection (marking "L" indicates that the terminal is phase, "N" - zero, "PE" - ground).
