Other sections

Then prepare the wires for testing by opening them apart to avoid touching each other. Following the rules of marking, the neutral wire is denoted by a Latin letter N, and the phase by the letter L... In order to determine on which of the wires what is being fed, use an indicator screwdriver, alternately touching the bare ends. In this case, the machine located in the dashboard should be connected, and the switch keys should be set to the "ON" position. If during testing the LED inside the screwdriver lights up, then this wire is energized and is a phase.

Having dealt with the wires, you should turn off the power supply again and calmly engage in installation work. When connecting wires, it is recommended to use terminal clamps; twisting with subsequent insulation with protective caps is also possible. Remember, PVC tape tends to dry out over time, which significantly reduces its insulating performance. Therefore, its use in this case is undesirable.

Chandelier installation. Options and opportunities

There are several basic options for connecting a chandelier, which can vary depending on parameters such as:

• the number of wires coming out of the chandelier;
• the number of wires coming out of the ceiling;
• number of keys on the switch.

A detailed description of each connection diagram will allow you to choose the most suitable option for installation.

Option number 1. Two wires on the chandelier and two wires on the ceiling

The easiest and most effortless chandelier installation option is to connect two-wire lighting fixtures to two-wire ceiling wires. In this case, it is enough connect pairs of wires, having previously determined the phase and zero. The order of connection in this case is not critical.

The neutral wire (in the diagram it is blue) coming from the junction box should be directly connected to the neutral wire coming out of the lighting device.

The brown wire that represents the phase is connected not only to the phase wire of the chandelier, but also to the switch.

When installing light sources with two or three lamps to a switch with one key, it is necessary to first connect all the neutral wires coming from the chandelier to each other, and only then to the neutral wire coming from the junction box. The wires with the phase are also combined, after which they are fed to the phase wire coming from the switch.

Option number 2. Two wires on the chandelier and three wires on the ceiling

Electrical wiring in modern buildings is carried out three-core cable, which contains wires of different colors. Accordingly, three wires are fed to the place of attachment of the lighting fixture, but there are only two of them on your chandelier. So how do you connect a chandelier in this case?

First of all, you should understand the purpose of the wires on the ceiling using the indicator. Two of them are phases, and the third is a neutral conductor. Two phase conductors provide for the use two-rocker switch, but since in this case we are considering connecting a chandelier with only two wires, a single-button switch will be enough.

Having previously de-energized the section, we insulate one of the phase wires, leaving a phase-zero pair. Next, we carry out the installation in the above described way.

Option number 3. Three or more wires on the chandelier and two wires on the ceiling

If only two wires come out of the ceiling, then there is only one option for connecting the chandelier, regardless of the number of wires coming out of it - all the bulbs in the chandelier will burn simultaneously.

To do this, connect all the neutral wires of the chandelier to each other and connect them to the neutral wire extending from the ceiling. The same operation is carried out with all the wires to which the phases are supplied.

Option number 4. Three or more wires on the chandelier and three wires on the ceiling

This connection option implies the use of switch with two buttons... This approach will provide the most efficient lighting of the working area by combining the sequence and number of lamps on the chandelier.

The three wires coming out of the ceiling are marked as follows:

• phase wire L1;
• phase wire L2;
• neutral wire N.

Since workers do not always adhere to the color scheme when laying electrical wiring, and also depend on the type of cable used, be sure to make sure the purpose of each of the wires. As mentioned above, the easiest way is to work with an indicator screwdriver.

If there is no such indicator, then you can disassemble the switch by first turning off the machine in the dashboard. After that, it is easy to determine which wires (what color) run from the switch to the ceiling. Remember that the phase wires will go to the switch keys, but the neutral wire goes away directly to the chandelier.

Connecting a chandelier, from which several wires come out to a switch with two buttons, differs in that the wires from the lamps are pre-divided into two sections. Each of the sections is connected to only one of the wires through which the phase is supplied, but both groups must be connected to the neutral wire.

With this method of connection, when one of the switch keys is pressed, one group of lamps will light up, and when the second key is pressed, another.

This connection allows you to connect as three lamps at the same time, and one or two lamps, when one of the switch keys is pressed.

In this example, the first switch key switches on 2 lamps, and the second switches on 3 lamps.

In this example, each key of the switch turns on three lamps.

Another example of connecting a 6-arm chandelier, when one key connects immediately 5 lights and the other is one.

Connecting a chandelier to a larger number of arms will be identical to the examples already considered. You just have to distribute the lamps into groups and connect them to a specific key.

Option number 5. Three or more wires on the chandelier and four wires on the ceiling

If the electrical wiring in the house or apartment has been completed relatively recently, then there is a possibility of additional pinch wire, which performs a protective function. This wire, usually yellow-green in color, will be the fourth wire that comes out of the ceiling. It is marked with Latin letters PE- grounding conductor. The rest of the wires are already known to us from the previous example. These are two phases L1 and L2, and null the wire.

If you have a yellow-green wire in your chandelier, simply twist it with a ground wire extending from the ceiling. If such a wire is not provided in the chandelier, simply insulate the yellow-green protective conductor on the ceiling.

How to connect multiple chandeliers to one switch?

This question is relevant for premises where it is located immediately multiple light sources... In large halls, this can be chandeliers, in living rooms - a group of halogen or LED lamps. It may also be necessary to connect lighting in several rooms at once. In this case, the connection is made according to the following scheme:

All chandeliers are connected in parallel. Each of the chandeliers can be connected to the switch through separate junction boxes, and depending on the wiring diagram, it can be placed in a single junction box.

How to connect three chandeliers to a three-key switch?

This connection option is very often used to illuminate the kitchen, toilet and bathroom. With a three-button switch in the hallway, you can easily turn on the required lighting fixture.

How to connect one chandelier to two different switches?

To implement a connection diagram for a lighting device from two spaced switches, you will need special pass-through switches... Such devices differ from conventional switches in design features and the presence of three contacts in the wiring diagram.

By connecting the wires according to the diagram, you can control the lighting from two switches at once.

As you can see in the figure, there are three contacts in the pass-through switch: a common terminal for connecting to a chandelier or a phase wire and two contacts with which the switches are connected to each other.

This distribution is necessary think in advance, preferably before starting repairs. Otherwise, you will need additional wiring, followed by cosmetic repairs.

Halogen lamps - advantages of use and connection diagrams

Halogen lamps greatly outperform their predecessors - conventional incandescent lamps, not only by the variety of the assortment on the market, but also by lower energy consumption. At the same time, their glow remains no less bright than that of incandescent lamps. Halogen lamps low voltage need a power supply for 24 , 12 or 6 Volts... The only requirement for connecting such lamps is the installation of a step-down transformer to convert 220 V from the network to the required rating.

To connect several halogen lamps, they must be connected to a step-down transformer, having previously paralleled them.

Transformers thanks to small size, can be placed directly in false ceiling frames. The number of fixtures and transformers may vary, but remember that each new transformer must be connected with separate wires that will converge in the junction box.

Place transformers at a distance of at least 20 cm from heat sources, while it is not recommended to exceed the length of the wires leaving the transformer by more than 2-2.5 meters... This arrangement can affect the luminance performance of halogen lamps.

Remote control chandelier - luxury or convenience?

Lighting devices with a remote control are the most modern developments in which control elements are already included. A chandelier like this will save you the hassle of crawling out from under a warm blanket to dim the lights in your bedroom and will help you avoid accidentally hitting corners and walls when returning to bed in total darkness.

Chandeliers with a remote control do not require additional knowledge during installation, because their installation does not differ from connecting other light sources. The fixing of such a chandelier takes place in one of the ways described above, and it will already allow you to control the lighting built-in controller.

At the same time, it is not recommended to get rid of the wall switch, because everyone has probably experienced for himself how long it sometimes takes to search for the TV remote control and repeatedly return from the next trip to the store without new batteries.
