Three wires protruding from the legs of the chandelier mean, for example, that we have a model designed for a two-key switch. As an option, an additional core serves to ground the case. In the event of a flood, the differential switch quickly removes the voltage, no one will suffer. A hypothetical case is possible when the body of the chandelier is under phase, and a short circuit does not occur. We see a similar picture when sealing poorly insulated wiring under the plaster: while the solution is damp, leakage currents are clearly going on. But when the cement stone is already grabbed, the negative effects disappear. Let's talk how to connect a chandelier with 3 wires.
Information about the electrical part of the chandelier
For the correct operation of a single cartridge, the presence of two wires will suffice:
- Phase( potential relative to the ground 220 V).
- Zero wire( potential is zero).
The cartridge is often combined with the base with a tube, from where the wiring follows up. Very rarely the switching is carried out inside the chandelier. As a rule, you can see where and what comes out. It is more appropriate to talk about whole bundles. If there are three:
- One end is considered grounding. It is appropriate for chandeliers with a metal body. There is no technical possibility to ground the chuck in the chuck.
- By modern standards, the color of wire insulation reveals their purpose. Grounding demonstrates green or yellow-green cambric. Blue is marked with a neutral wire, the phase is brown or red.
In flats, the situation is often different; white or black colors may hang out of the chandelier. Find two ends, where to start the phase and zero, it is easy. To do this, you need a light bulb or a small piece of copper conductor. With the help of these things, we short-circuit any cartridge and the tester will check the resistance between the three ends. In one case, the display will show the value 50 - 100 Ohm( typical value of the resistance of the filament spiral).
A short circuit happens between two wires that extend structurally from a common direction. Then you want to call the branch with the body. Resistance equal to zero means that inside the closed zero wire per phase. If the house has a power supply system with a ground wire( TN-S, TN-C-S), you will need to open the chandelier and separate the indicated ends. Without losing the right to a guarantee, however. It is not allowed to combine at the end of the consumer of the zero and ground wires.
Connecting the wires
Let's give a couple of recommendations on how to connect the wires on the chandelier:
- When a branch goes out in pairs, you just need to split any presented into two wires. Then two large bundles are formed, the first is connected to the neutral wire, and the second to the phase. Notice that the wires coming out of the branch must be separated. If you connect them to a single bundle, the worst will not happen, but the system will not work.
- The third wire is sometimes ground. This definitely can not be connected to the phase, and the core should ring on metal parts. It happens that plastic inclusions separate conductive islands, we assume that there are more wires in order to reliably ground dangerous areas. Veins call in turn with each to find the ground. Then it is necessary to carry out marking. Enough single color - marked ground. If it is not combined with the neutral wire, there is no difference in connecting the other two ends. Otherwise, the phase of the chandelier is marked so that the voltage does not accidentally apply to the body.
Electricians try to apply a phase to the central contact of the cartridge( a straight line entering the center from the periphery).Lunar shaped as good. If you wish, get a tester and find out where the wires go. This will add to the orderliness of electrical wiring, for most people it will not come in handy. Recall that the thread of the cartridge does not carry a charge and is often not connected anywhere. Otherwise, any electrician who wanted to get inside during the time when the system is energized would risk a short circuit or worse.
After manual switching, it is possible to check the wiring correctly. It is advisable to put a chandelier on an insulating surface. It sounds difficult, but find a sheet of chipboard or sound insulation, insulation made of polymeric materials at home. Metal does not fit. Stay away from any grounded metal structures: heating radiators, water pipes, gas supplies, sewers. The wires of the chandelier, which are planned to be connected to the phase and the neutral wire, will need to be plugged into an outlet. You will need to assemble the fork and dock the ends with a twist. Food is fed, testing begins.
During the process, it is required to ensure that a voltage of 220 V comes to a specific contact of any cartridge. Before starting operations, the potential of the body is evaluated. Easier to make a screwdriver indicator. Modern, by the way, allow us to evaluate the presence of grounding, if the third wire is designed for these purposes. For example, the screwdriver-indicator lights up when the phase is touched, and reacts to the ground by pressing a finger to the contact button. Such moments are prescribed in the instructions. It will be possible to immediately assess the correctness of the connection in this part. Of course, the socket is taken properly connected, and the plug for the test - with a grounding terminal.
In the extreme case, if there are no TN-S or TN-C-S systems in the house, it is allowed to combine this branch with the neutral conductor. Typically, the screwdriver indicator does not object to maneuver. The purpose of the story comes down to the fact: in the presence of a large number of twists, the display can be broken, and the chandelier wiring diagram will cause a lot of trouble. As a result of testing, it is foreseen that the electrical wiring is correct.
Chandelier on the
two-button switch We talked mainly about grounding through the third wire, but more often it is displayed so that the cartridges present can be divided into two parts. Similar needs arise in the halls, where you want to receive full illumination to receive guests, and to reduce consumption on weekdays. With the advent of LED lamps, there is a desire to extend the experience with chandeliers to other rooms. For example, a packet with a total luminosity above 2000 lm( 200 watts of consumption as applied to incandescent bulbs) takes 30 watts from the network.
Get more light for less money. Efficiency chandeliers increased. To connect you need to split the ceiling in two groups. Usually do alternately. If the number is odd, in a particular place the branch of the key falls on the adjacent cartridges. Groups then differ in number, the difference is one. Switching is carried out according to the scheme described above. If there are three wires, grounding is clearly absent. It is important to understand where the phase wire is connected. In this case, presented two.
double switch. Visually, the only end of the earth looks thicker. This bundle combines the zero branches of all cartridges without exception, which is difficult not to notice. Therefore, the other two groups are considered phase and are connected to the output from the switch buttons. Before said, how to understand whether the connection is made correctly. Repeat: on the cut down switch with two keys, the phase is only on a single contact out of three. After turning on both keys, the screwdriver indicator should indicate the presence of voltage at all. Means - from the switch the phase moves as it is necessary.
If done the other way around, the voltage may be absent or be observed simultaneously on two contacts. Before connecting the chandelier with three wires, it is necessary to switch the wires correctly. Already described in detail the process and will not be repeated.
Often there is a need to connect a chandelier to a double switch instead of a typical one. We mentioned that the light becomes cheaper, the efficiency increases, people want illumination. All cartridges are allowed to start immediately on a single phase. Most electrical equipment in residential buildings is calculated on a current of 10 A, which corresponds to a power in the region of 2 kW.Even if the chandelier dial 10 LED lights, up to the limit far. Feel free to combine the two phase contacts of the chandelier with three wires and start with a common key.
It is more difficult for those who wish to replace the old lamp, so that there are two buttons, it will divide the ceiling lamps into groups. Usually in the walls there are channels. Clearly visible on the example of prefabricated houses. If you look into the socket of the switch or socket, you can see the channels going deep into the plate. Not all are used( see photo), there are ample opportunities to optimize the design. Using special cable laying devices( broaching), any experienced person will lay the wires correctly. If you want to connect the chandelier to a double switch, you need to draw a diagram and stretch two wires:
- From the junction box to the place where the chandelier is hung.
- From the switch to the junction box.
Please note, the phase should already be approached from one side to the switch, therefore we do not touch this branch. On the side of the chandelier, the neutral wires of both groups are combined. For greater clarity, the scheme of work presented in the figure. The new branch is shown in green, gray circles in the junction box schematically shows the twist or other variants of the connections of the wires. It happens, the entrance to the channel is blocked with mortar, large pieces of stone are inside. It is recommended to be patient with a two-button switch so as not to break the broach. If it bends, straightening is no longer possible.
Chandeliers with remote control
Usually, connecting a chandelier with a remote control is no more difficult than an ordinary one. The receiver, as a rule, works directly with a dimmer( supply voltage regulator).Not all LED lights support mode. Chandeliers with a control panel are not recommended for individual models. The difference in price is 20%, but you have to pay so that the product worked for a long time and reliably.
Sometimes there is a need to change the cartridge in the chandelier. Incandescent bulbs emitted a lot of heat, the insulator material and contacts become useless from the many years of operation. Modern cartridges are quite suitable. Recall that the standards have changed a lot, the diameters of the mounting and installation holes have changed. From the point of view of machining, it is better to prefer plastic( black and hard) to carbolite. So it is easier to drill and grind, changing the chandelier. By the way, electricians are reluctant to undertake such work, such trifles are not part of their duties.
If the hole in the base of the carbolite is slightly smaller than what is needed, it is extremely difficult to expand. Mostly have to wield a round file.
