Connecting a chandelier to a double switch: diagrams + installation rules
Chandelier not only complements the overall design of the room, but also serves as a source of light in the dark. However, the maximum possible level of illumination is not used as often, right? For the most part, there is a need to use the economy mode, when only a part of the lamps are functioning. Therefore, you want to connect the chandelier to a double switch, but do not know how to do it correctly?
We will help you to deal with all the nuances of this process - the article provides diagrams for connecting the device to a switch with two keys. The main errors that make novices in such schemes are considered. After all, only the correct connection of the wires will allow control, providing comfortable lighting.
The material of the article is provided with photos, diagrams and recommendations in a video format for correctly performing the connection of the chandelier on its own. Having studied the basic rules and schemes of installation, you can get to work.
Work with electrical wiring should be carried out in compliance with safety regulations and with a clear sequence of actions.
First of all, the rules relate to de-energizing the wiring during the process of fitting and stripping wires, installing the operating mechanism of the switch, connecting conductors to the terminals, etc.
However, to determine the desired wire, you still need power supply, so you need to be as careful as possible in the work and perform all actions only with special tools with high-quality insulation of the handles.
Installation of a double switch is carried out only in the gap conductor phase.
When inspecting the completed scheme, it is allowed to turn on and off the lighting devices only after complete insulation of the bare wires and their final fixing.
The use of double switches
Connecting a chandelier to an electrical circuit on a double switch allows you to alternately use a group of lamps, and turn on the lighting device at full capacity.
In this case, the two-phase device can be triggered by interacting with only two groups, the number of lamps in which is unlimited.
Such adjusting fittings can be used in a private house, where the first line feeds outdoor lighting, and the second - a corridor, also in apartments, distributing electricity between the two rooms of the bathroom.
The two-button switch is a pair of single-button ones, completed in one case, therefore the connection scheme is almost identical.
To reproduce the installation plan, it is initially necessary to become familiar with the design features of the product and with the elements connected to the electrical network.
Device device with two keys
There are a lot of modifications and types of light switches. However, two-button electric accessories gained popularity relatively recently, when lighting was reproduced using multi-lamp chandeliers.
So there was a need for the distribution of light through zoning spotlights.
No. 1 - model of self-tightening terminal block
The instrument case has standard parameters. Depending on the modification, it can be laid on or built-in, easily mounted on the external or internal part of the wall.
The second type is equipped with adjustable locks. With the help of screws, the instrument case is mounted in the desired position.
For fastening wires in modern versions of accessories used plate clips or clamping plate with screws.
The screwless model is widespread and simply indispensable for self-installation for beginners. The wiring diagram and the distribution of contacts in most cases is shown behind the case.Common mark values are also used.
Basic symbol - Latin letterL, meaning contact for phase conductor. Beside a pair of arrows pointing down. They are interpreted as an indication of the direction of the two outgoing phases. The same meaning is carried by the numbers indicated on the place of the arrows.
The left side contains double contacts of the first switch key, the right one - the second.
Based on the connection method, each of the keys can supply voltages in different directions, for example, turn on several lamps of a luminaire or illuminate a room located nearby.
For each of the conductors has its own purpose, so the best option is to use a cable with wires of different colors. This will greatly simplify and speed up the wiring process.
No. 2 - connection of screwless model
The process of connecting the self-tightening contacts is much easier compared to screw.First of all, turn off the power supply. Further, all the conductors of the future contact must be cleaned of 1 cm of insulating material.
Each contact provides for fixing one pair of wires. The stripped wire is inserted all the way into the corresponding hole in the mechanism.
After turning on the electricity you need to calculate the phase of the power supply. An indicator screwdriver is used for this purpose. After checking, the supply of current must be stopped.
Following the scheme indicated on the back side of the working part of the switch, it is necessary to alternately connect the colored wires, distributing them among the keys.
Consider a detailed action plan for a specific example.
In our example, the red supply phase is connected to the red wire that goes to the common contact of the on / off switch.At the exit of it already turns two wires - burgundy and yellow.
Burgundy wire is routed to the junction box. There he connects to an identical-colored contact and goes to the first group of chandelier bulbs.
According to the scheme, the phase contact of yellow color, going to the distributor, should be connected to the same-colored wire going to the second group of luminaires.
The zero shown in the blue diagram, also emanating from the apartment’s electrical panel, goes directly to the junction box, and then to the terminal block where the zero of each of the chandelier lamps group is connected.
Similarly, the zero conductor goes yellow-green, responsible for the earth.
When installing and connecting a double switch, its working mechanism is hidden in the socket, fixing it in the desired position with a screw fastening. Next on the device put the keys and a decorative overlay.
№3 - installation of screw contacts
In this case, there is no schematic indication. Visually, it is necessary to designate the two lower contacts, which, most likely, represent the outgoing phases, and the upper one - the feeding phase.
You can make sure that the actions are correct by methodically turning the contacts on and off: when the keys are on, the circuit closes, in the off position, the circuit opens.
The mechanism of this type of switch is equipped with three screw contacts, through which the wires are connected, and two screws that actuate the spacer legs.
For screw-type contacts, it is necessary to clean the cores by 0.5 cm. Fixing of the cores is carried out using a plate that is driven by screws.
Check for correct wire connections
The primary task is to inspect how correctly the circuit breaker was connected.On one of the lines, the voltage indicator in the open position should indicate the presence of a phase potential.
On the place where it is planned to install the chandelier, two conductors should go out, namely the neutral and phase wires coming from the switch.
The number of conductors at the device itself will be more, especially when a multi-track lamp is connected. It is also possible to have a grounding conductor if electrical wiring with a grounding system is operated in the house.TN-C-S.
In order to properly distribute the purpose of each cable, it is necessary to check whether they have voltage. There are several special devices for this: indicator, voltmeter, digital multimeter, etc.
It is easy to work with the voltage indicator: it is necessary to touch its tip to the insulated section of the wiring.
Only one cable does not illuminate the device — zero; the others, when in contact with a screwdriver, will cause it to glow — a phase. Switching two keys of the switch alternately will help to recognize the accessory of the wire to the desired key.
A similar method of determination is used when measuringdigital multimeter. It must be set in the "Volts" mode and the scale must be set to more than 220 V. Alternating, it is necessary to touch the wires to the probes.
Phase pair will not lead to changes on the dial of the device. Connecting probes possible phase and zero, you can observe on the indicator the figure of 220 V. If the wiring has the same color, it is better to mark it with markers.
Interpretation of marking of electrical wires
For ease of identification and to avoid confusion, the insulation of the cable cores is colored. According to the standards, the ground wire is yellow with a strip of green tint.
Such a conductor is found in new buildings, where a high level of protection against electric shock is provided.
The marking of a neutral conductor is carried out by an insulating sheath of blue or blue color, in which the core is enclosed. For the phase can be applied any other variations of shades, except those indicated.
The connection of the chandelier and other lighting devices is carried out by pressing, soldering or by means of terminal adapters.
The first option provides for the connection of conductor cores by crimping them with a fixing sleeve. The whole procedure is carried out by a special tool - press tongs. This method complies with all regulatory documents.
The second method is considered one of the most reliable, but difficult to reproduce. It is practically not used because of the inconvenience of working at height.
Aluminum and copper wires should not be twisted together - a galvanic couple is formed, which, even with a slight increase in the humidity level in the apartment, can reproduce the electrochemical reaction in the form of oxidation.
This process breaks the contacts, and the docking place begins to heat up. It is for this reason that fires are formed.
The use of terminal strips is considered relevant. At the moment, the model range of this connecting element is quite wide - from the classic screw version to the spring modification.
How to connect a chandelier?
If you pay attention to the five-horn chandelier, there is a fairly large number of wires in its arsenal, so inexperienced craftsmen avoid such lighting fixtures.
However, there is nothing difficult in the process of connecting the wires going from the distributor to such a lamp.
First of all, it is necessary to understand the wiring on the ceiling, which in the standard situation has three wires:
- Phase of the first key switch. We denote this veinL1.
- The second key phase isL2.
- Zero -N.
If the wires are the same in color, then the belonging of each is determined using a voltage indicator, i.e. phases L1 and L2. Accordingly, the remaining vein will be zero.
Then you can proceed to the process of forming contact points. Consider the example of a five-arm chandelier, which has 10 wires: brown phase conductors - there are 5 of them, and the same number of blue ones.
This lamp has one indisputable advantage - the combination of light bulbs can be made at your discretion. According to the scheme described below, the first group includes two light bulbs, the second - the other three.
Proceeding from this scheme, the connection of the five-horn lighting device is carried out in several stages. Initially, a pair of brown wires is completed in one node.
It is desirable that the lamps included in one series are connected in parallel. This twist is calledL1.
The next step is a similar twist of the unused three brown wires. It will be a seriesL2. Next, the resulting two nodes are inserted into the two-wire terminalWAGO clips.
In the next step, blue wires are twisted and connected to a three-wire terminal.
The order of connection does not matter. The combination may be 3 + 2 or 2 + 3. This will be a neutral node -N.
The output results in 3 connection nodes: the phase of the first and second lamp groups is L1 and L2, the common neutral node is N. Given the marking of the wires, they must be connected to the corresponding lines on the ceiling.
At the final stage it is necessary to lay all the wiring in the lid of the bowl of the chandelier and install it. Fastening is performed in one of the ways: it is hung on a hook or fastened with screws. Next, tighten the decorative caps of the lamp.
Ground Wire Application
When arranging electrical communications in new homes in accordance with generally accepted standards, a wiring wire will be present in the wiring.
In such premises when installing the chandelier, you can find that 4 wires go out of the ceiling: two phases from the switch, zero and ground.
In most models of chandeliers with two groups of lamps and metal parts, the terminal block through which the ground connection is made is provided.
In the process of installing the lighting device, you need to pay attention to this and connect the wire.
Halogen lamp connection
Chandeliers with halogen lamps do not always operate on 220 V AC mains - these can be products designed for 6, 12 or 24 V alternating voltage. Therefore, in the second case, a step-down transformer will be needed.
Sometimes the manufacturer in each model of the lighting device operating on halogen lamps, embeds special transformers to reduce the current.
In this case, the scheme is already assembled and it remains only to install it. Two cables remain unused, which are connected to the ceiling wiring, while the connection is made arbitrarily.
Chandeliers, the package of which includes a remote control, can be of various modifications: with halogen, LED or incandescent lamps.
There are models and combined type. Such a device is complicated by the presence of a radio control unit. In essence, this controller is a wireless device that is controlled by a remote control or a standard key switch.
The connection of such a lighting device is similar to the previous model, however, one more wire will be added here, the thinnest of all.
This is the antenna through which the communicating actions of the console and the controller are reproduced.It remains unchanged inside the glass of the chandelier.
Conclusions and useful video on the topic
The whole process of preparing the chandelier to connect and directly connect to the power of the double switch is described in the video:
Inexperienced masters often make mistakes in the process of wiring, which ones and how to avoid them, see in the video:
If you reproduce correctly all the stages of installation and follow the scheme, you can protect yourself from unpleasant consequences during the direct operation of the lighting device. Moreover, it will be possible to create a unique light atmosphere in the room, adjusting it to fit your needs.
