How to fix the lamp and chandelier on the ceiling. How to Hang a Chandelier on a Concrete Ceiling DIY Chandelier Hook

17.05.2020

How to hang a chandelier from the ceiling with your own hands? It would seem like a question. Slide the upper cap of the chandelier down, hang it on a hook, connect the wires, slide the cap on - that's all. But even in this, the simplest case, difficulties can arise. Which? Let's figure it out.

How are chandeliers hung?

There are four ways to hang chandeliers:

The ceiling hook is the oldest and most reliable. Requires a solid ceiling and special fastening in it.
Standard mounting plate (bracket) - due to the distribution of the load on several attachment points with a small weight of the chandelier, it is quite reliable when fastening with dowels and nails into plastic sleeves.
The cross mounting plate works similarly to the straight mounting plate, but has more attachment points. It is used for chandeliers-plafonds adjacent to the ceiling.
The I-beam mounting platform is designed for mounting heavy chandeliers at several points.

All these mounting methods do not allow you to pull the chandelier close to the ceiling in low rooms. Mounting strips are curved to allow wires to exit. Further in this article, the refinement of the mounting plate will be described, which allows you to press the chandelier close to the ceiling.

Installation of regular fixtures of chandeliers is simple: self-tapping screws in clips-sleeves. The diameter of the self-tapping screws can be determined by the mounting holes in the mounting plate; self-tapping screw length - 40-60 mm. For low ceilings, it is preferable to use ceiling chandeliers, without a rod.

Much more attention should be paid to safety when installing chandeliers: when working on a hill, even a slight electric shock is fraught with a fall and serious injury. Various kinds of non-standard situations related to the suspension and installation of chandeliers will also be considered: suspended ceiling with a chandelier, how to hang a chandelier on drywall.

Phase indicator and wire phasing

First of all, you need to check the phasing of the wires for the chandelier. The neutral wire (neutral) is common, and the phase wires are connected to the lamp sections through the switch.

Phase / zero wiring is determined by a special device - a phase indicator. It can be purchased at any electrical supply store. The indicator is inexpensive. Phase indicators come with a neon light bulb and a quenching resistor and electronic ones.

The indicator looks like a screwdriver. When using it, the device is lightly clamped between the index and middle fingers of the right hand in the place intended for this; it is either highlighted in color, or has a notch and is separated from the sting by a safety cuff. TOUCH INDICATOR STING DURING OPERATION DANGER TO LIFE!

When checking the phasing, the thumb touches a special metal terminal on the end of the device handle, or a button in the electronic indicator, and the indicator sting touches the wire under test. If it is phase, the lamp flashes or the corresponding symbol appears on the display. IT IS IMPOSSIBLE TO HOLD THE WIRE WITH THE OTHER HAND, EVEN FOR THE INSULATION! The indicator works ONLY ONE - RIGHT - HAND!

Before checking, turn out/turn off BOTH plugs. Then the ends of the wires for the chandelier sticking out of the ceiling are exposed, the ends are spread apart, the plugs are turned on, and the switch is turned on. A stool is placed on a rubber mat, and from it, right hand, the indicator finds a phase wire or two phase wires, if the chandelier switch is double. Then the switch is turned off without touching the plugs, and the phasing is checked again. Now the indicator should not glow when you touch any of the wires.

If the phase remains somewhere, the switch must be switched to a phase break, and the neutral wire, if the switch is unipolar, should be switched directly. This work is simple, and picking the wall is not required. But, if you are not an electrician, then you need to invite a specialist for it. No jokes with electricity are in vain.

Search wiring

Before drilling holes for fasteners in the ceiling, you need to determine where the wiring lies so that you do not interrupt it when drilling. For reliability, the search for wiring must be done under load, i.e. under current. Give the load on the wiring as follows:

Turn off the plugs and the chandelier switch.
The wires sticking out of the ceiling are temporarily increased to the floor; joints are insulated with electrical tape.
Instead of chandelier sections, cartridges for incandescent lamps are also temporarily connected.
Light bulbs are screwed into the cartridges by at least 60 watts, and better - by 100-150 watts.
Plugs and switch included; you can start looking for wiring.

The search for wiring is best done with an electronic indicator; neon indicator works only in direct contact with live parts. There is special devices- wiring finders, but they are more expensive, and the accuracy is no more than two thicknesses of plaster. If the wiring is also hidden in strobes, then the error will be about 5 cm, which is not enough. The indicator at any depth of occurrence gives an accuracy of 1-2 cm.

The indicator is led by placing a finger on the button along the ceiling perpendicular to the intended direction of wiring. When the phase icon appears on the display, make a mark with a pencil and drive on. When the icon disappears, a second mark is made.

Then the same place is passed in the opposite direction; there will be two pairs of marks. In the middle between the internal and lies the wiring. Then they shift by 15-20 cm along the wiring and the search is repeated until the end of the working area.

Mounting the chandelier on regular fixtures

Mounting a chandelier on standard fixtures comes down to wiring power wires for sections of light bulbs. When checking the phasing of the wiring, the neutral wire must be immediately noted somehow, at least by bending it close to the ceiling with the indicator sting. Then the plugs are turned out / turned off and the wires are brought into the chandelier.

In modern electrical appliances, the neutral wire is always yellow with a longitudinal green stripe, and all wires are pre-wired into the connector - the terminal block. The neutral wire of the wiring is connected first: insert it into the neutral terminal and tighten the screw. Then the phase wires are connected. They push the cap to the place - the work is over.

And if the wiring in the room is of two wires? Or grandfather's chandelier, or antique, and you can't see where the phase is, and where is zero?

In the first case, a small piece of the same wire section is added to the phase wire (PLUGS - OFF!) And both sections of the bulbs are switched on for one phase. The whole chandelier will be turned on with one switch.

chandelier

If the wires in the chandelier are not marked, and there is no terminal block, then the chandelier needs to be ringed. This is done by a regular tester. RINGING THE CHANDELIER WITH A CONTROL LIGHT FROM THE 220 V NETWORK IS DANGEROUS TO LIFE!

For continuity, we screw the SAME into all the cartridges of the chandelier, i.e. one power and brand, incandescent lamps; better low-power, 15-25 watts. Housekeeper light bulbs are no good, dialing them will not work.

The scheme of the chandelier is given in the figure. From it, a person familiar with electrical engineering or at least not forgetting Ohm's school law can see that if the resistance of one light bulb is R, then there will be R between zero and FI; between zero and FII - 0.5R, and between phases - 1.5R. To ring three wires in pairs, six measurements are needed.

"Special" chandeliers

Recently, chandeliers have appeared on sale, equipped with a remote control for adjusting the light, a fan, an air ionizer or even an air conditioner (more precisely, its evaporative unit). When buying such products, the following rules must be observed:

See how it connects right now. If, in addition to the usual terminal block for household wiring, some strange ends stick out there, ask for instructions and read it.
If it is not clear from the instructions how to hang such a chandelier yourself, ask if its installation is included in the price of the product, and what are the seller's guarantees.
Suddenly, the outlet works on the principle of “sold and forgot”, it is better to look for the same thing elsewhere.

Chandeliers with additional functions - products are quite specific; there are few firms or craftsmen involved in their installation, and “special” chandeliers are not cheap.

emergency situations

And how to properly hang a chandelier on the ceiling if there is no regular fixture, or it cannot be used? To do this, you will have to stock up on a tool for working on concrete, stone, wood, drywall, and work.

Low ceiling

The standard version is a chandelier-plafond and fastening with a cross bar. But what if the room is low, but you still don’t want to install a ceiling? In this case, you can gain 10-15 cm by hanging a chandelier with a rod on the ceiling without a hook.

To do this, the standard mounting plate is straightened, cut so that it is hidden under the cap, and new holes are drilled in it for self-tapping screws. Next, the chandelier needs to be slightly modified:

Lights and, if possible, all fragile details are removed from the chandelier. It is better, if the design allows, to remove the rod immediately.
The wires of the chandelier are removed from the terminal block.
In the rod, immediately behind the thread, drill in a row along the rod, three holes 4-5 mm. You just need to make sure that they are all under the cap.
Three pieces of fishing line are passed into the holes of the removed rod. Their ends are attached to the ends of the wires of the chandelier and tightly wrapped with narrow tape.
The rod is put in place, gently sliding over the wires and pulling up the pieces of fishing line until the ends of the wires come out of the holes. If one is caught, it is corrected with a wire hook or tweezers.
If the rod is non-removable, then pieces of fishing line are inserted into the holes one by one, starting from the bottom, and the wires are also brought out into them.
The wires are reintroduced into the terminal block.

The purpose of this refinement is to bring the wires to the side so that they are not pressed against the ceiling and transferred by the edge of the rod. Attention: if the rod is fixed or curly, the cap must remain on it. Otherwise, he will not get dressed later because of the wires sticking out to the side.

Next, a mounting plate is installed on the rod between two regular nuts, and the chandelier is attached to the ceiling with screws. Most likely, nuts will not be needed: in most chandeliers, the bar is attached to the rod by flaring.

Connect wires. It may turn out that the terminal block now does not fit in the cap - it's okay, it is completely removed, and the wires are connected by soldering; joints are insulated with electrical tape. It is not recommended to connect the wires with a twist: there will be problems with a flashing chandelier later.

Now we mount the chandelier to the ceiling with self-tapping screws. We do not tightly wrap the screws into the sleeves, otherwise the chandelier will become oblique.

Option for weak but dense ceilings: laminate, MDF, plywood. Instead of a mounting plate, we make a circle with a diameter of 5 mm less than the inner diameter of the cap. In the center - a hole for the rod; in a circle - 4-6 holes for self-tapping screws. You will also need to make a hole for the wires.

If you need a hook

Fixing a chandelier to a concrete ceiling on a plank or I-beam does not raise any questions. And if the chandelier you like is hooked, but it is not at home? A little work - and a very reliable hook you can put yourself:

If a hook-screw is used, then in the ceiling we drill a hole with a diameter of 10 mm more than the diameter of the screw, and a depth along the length of the thread + 10 mm.
Lubricate the thread of the hook with a thin layer of consistent (thick) lubricant.
We tightly wind two copper wires with a diameter of 0.8 - 1.2 mm onto the screw thread. At the beginning and at the end of the thread, we leave a mustache of 10 mm and spread them 90 degrees. When viewed from the end of the screw, the mustache should diverge in four directions perpendicularly.
We spray the hole inside with a spray bottle, or stick a richly moistened cloth into it with a stick, hold for 1-2 minutes and take it out.
We prepare 50-100 g of alabaster or gypsum mortar; this is convenient to do with a disposable plastic cup. When mixed with water, the solution heats up. Mix until creamy consistency.
Using a stick (not a spatula), as quickly as possible (alabaster and gypsum harden quickly), we fill the solution into the hole until it is filled.
Just as quickly, into the still liquid solution, we push the hook with the wire wound around the thread; the whiskers of the wire will be bent.
We remove the squeezed out solution and wait for it to solidify in the hole. The solution should not only solidify, but also cool down to room temperature. This takes at least 2 hours, but it is better to wait a day. Now the chandelier can be hung.

If a hook with a support platform for fastening with self-tapping screws, we make nests for them in the same way, but we take a thinner wire - 0.4-0.6 mm. And you will have to knead a separate portion of the solution for each nest - it hardens very quickly to a mushy state.

Such nests serve for centuries without shrinking like plastic. When wrapping / turning the hook 2-3 times, the socket does not loosen. If necessary, it is easily cleared of filling with a narrow chisel and redone. When repairing a gypsum-alabaster nest, you can plaster it, and then dig a hole in the plaster for a hook.

Chandelier in the stretch ceiling

Installing a chandelier on a stretch ceiling is the most difficult case. First of all: a chandelier with incandescent lamps and a stretch ceiling are incompatible. Even from a three-arm chandelier with 40 W lamps, spots will appear on the ceiling in a month, and within 3 months it will begin to creep. Economy light bulbs in chandeliers recessed into the ceiling quickly burn out due to poor heat transfer; The only option here is LED bulbs.

Then, installing a chandelier in an existing stretch ceiling is impossible: it will have to be removed and a new one installed. Trying to cut holes in already stretched ceiling useless - the film or fabric will immediately spread.

And finally, before calling the ceiling masters, you need to prepare a fixture for the chandelier. The regular fixture of the chandelier is not designed for installation in stretch ceilings, therefore, if the chandelier is hung on a hook, it must be installed in the ceiling in advance.

For mounting on planks or I-beams on the base ceiling, you need to attach a pillow made of waterproof BS or MDF plywood, at least 16 mm thick, on the brackets, as shown in the figure. A wooden or ordinary plywood pillow in the inter-ceiling space will soon dry out, and this will end in an accident.

According to the installed pillow, the ceiling mounts will take measurements and make holes in the panel, framed by grommets. Through them, the chandelier will be attached to the pillow with long fasteners, with a gap for the “play” of the ceiling. Wide holes are additionally reinforced with "spider" supports, but this is a subject for a separate discussion.

If it is supposed to drown the chandelier in a stretch ceiling, then it should hang in place during the measurement. But still, a chandelier in a stretch ceiling is not the best way on expenses. Only due to the uneven distribution of the load due to the presence of holes, such a ceiling is more likely to sag and lose its appearance than a solid one.

Chandelier on plasterboard ceiling

Attaching a chandelier to a plasterboard ceiling is also not easy, but still easier than in a room in stretch ceiling. There are three possible cases here:

The chandelier weighs up to 3 kg and is mounted on a hook. In this case, you need a special butterfly hook. It consists of a specially designed plastic clip and a screw hook. A hole is drilled in the drywall under the butterfly clip, the hook is screwed into the clip one or two turns. Then the clip is inserted all the way into the hole and the hook is turned to failure. Inner part butterfly unfolds into petals, which fix the hook.
Chandelier - up to 7 kg in weight. In this case, only fastening on slats (console) is permissible. A butterfly dowel is used for each attachment point; simply a mole. By design, it is similar to the cage of a butterfly hook, and when a self-tapping screw is screwed into it, it opens in the same way to the sides inside the interceiling space.
Heavy chandelier. To hang it on a hook, you will need one collet pin with a diameter of at least 12 mm; for mounting on a bar - at least two 8-10 mm each. To install a collet stud in the base ceiling, holes are drilled through drywall along the diameter of the stud sleeve and a depth in its length. The stud is screwed a little into the sleeve, inserted through the hole in the drywall into the base ceiling until it stops, and again the stud is screwed all the way. The collet diverges and wedged in the base ceiling, and a threaded end remains on the outside, onto which you can screw a hook with a threaded socket, or several ends - you can put a pillow on them under the chandelier bracket.

Finishing renovations or moving to new apartment, many inexperienced builders are wondering: a how to hang a chandelier on the ceiling? Let's make a reservation right away that it is difficult only at first glance. But after mastering the initial skills of fixing the chandelier, the problems will disappear on their own.

Note! Of course, you can always go to the housing office and call an electrician to your house who will do everything for you, but this option is definitely not ours (we do everything with our own hands!), Especially in such a simple matter.

The electrical aspect of the issue

You most likely saw a hole in the ceiling from which wires stick out (usually three - two phases and one zero). First, determine "xy from xy", for which take an induction screwdriver and touch the wires in turn. And if the light in the screwdriver lights up, then the cable is phase, and if not, then, accordingly, zero.

Note! Touch only the bare part of the wire with a screwdriver, and in the absence of such, strip it after de-energizing it (using a switch or shield in the entrance).

Then do the same with the chandelier - determine by ringing or “by eye” all the wires. If there are several lamps in the chandelier, then put the switch on two keys and make sure that when one button is pressed, only part of the bulbs are lit, and when the second is pressed, the entire chandelier is lit. This can be done by a special connection of wires using terminal blocks, shown in more detail in the diagram.

Having decided on the wires, you can hang the chandelier: zero to zero, phase to phase.

How to hang a chandelier?

Now that everything is clear with the "electric" issue, you can hang the chandelier. This can be done in one of two ways - on a hook or on a decorative bar. Let's talk about each method.

Hanging a chandelier on a hook

Take and drill a small hole in the ceiling. If there is such a hole, simply insert a plastic dowel there and screw in a pre-prepared hook. Connect the wires, wrap the connection points with insulating tape, cover everything with a decorative “cup” (it should be included) and make a test switch on.

We hang a chandelier on a decorative bar

To hang the chandelier in this way, you again need a puncher. First, attach the bar to the place of the planned fastening and mark the places for the holes. Make holes of the appropriate diameter, insert plastic dowels there (only be sure to be corrugated!).

At the next stage, take self-tapping screws or screws and use them to fasten a decorative strip to the ceiling. As in the previous version, connect the pre-prepared wires, fix the chandelier and cover everything with a decorative "cup".

R eat question how to hang a chandelier or other ceiling lamp You can use the services of an electrician. Or, with the help of our article, hang the chandelier yourself. Installing a chandelier with your own hands is a simple task and the only difficulty is that you may need a puncher (literally for five minutes of work). If you just decide to change the old chandelier, and the old chandelier is in good condition, then all you need is screwdrivers (Phillips and narrow, 2-2.5 mm slot), and small pliers.

Choosing and buying a chandelier

After you choose in the store suitable model lamp, you will most likely be given it unassembled. You can ask for the chandelier to be assembled right in the store, but it’s not very convenient to carry a bulky, fragile device in your car, and there’s no need to talk about public transport. When making a purchase, carefully check the complete set of the chandelier, especially the fastening details, so as not to return to the store later for a tiny nut. We recommend a good online store where you will find the widest selection of chandeliers and other lamps with delivery throughout Russia.

Modern inexpensive (up to 5 thousand rubles) models, with all the external diversity, have only two types of mounts. A loop that clings to a hook in the ceiling, shown in the pictures below, or a mounting plate fixed to the ceiling, to which a chandelier is then attached with bolts and decorative nuts, the section can be seen in the pictures below. The attachment point is closed with a decorative overlay - a cup moving on the suspension of the chandelier. The cup is fixed in the raised position, either due to a tight plastic washer, or a small bolt. In the second variant, the decorative overlay is often at the same time an element of fastening, we will tell you how to hang such chandeliers later.

Chandelier assembly

How to assemble a chandelier is usually clear even without instructions (which, by the way, are often not given!), however, a little advice - if possible, take a picture of the assembled chandelier in the store, at least with a mobile phone, less later you have to break your head. When assembling, do not be too lazy to check the wire connections, there were cases when the lamps did not light up when turned on, or even a short circuit occurred.

The assembled chandelier must be fixed on the ceiling, that is, hang the chandelier. In the very simple version, this is a regular hook. Alas, the easiest option is not always the best. The fact is that the height of the decorative “cup” is not always enough to close all this rather bulky structure, and an ugly gap remains between the lining and the ceiling. If you bend the hook, then putting some types of loops on it becomes a problem.

How to hang a chandelier with a hook

However, hanging a chandelier with a hook is, in most cases, convenient and secure. There are several types of anchors. If you need to hang a small lamp, weighing a kilogram and a half, you can use a regular screw-threaded hook screwed into a plastic plug - dowel. For heavy chandeliers, it is necessary to use expansion metal anchors, with a length of fifty and a section of ten millimeters.

The fastening device with a hook is performed as follows, a hole with a diameter of at least 8 mm is drilled in the ceiling with a puncher for a plastic dowel or anchor. When using plastic dowels, corrugated ones are used, at least 40 mm long. It is better not to use smooth dowels; they are held in the slab much worse. If, having drilled a hole, you fell into the void of the plate (which happens often), it's okay, the dowel will fix even better.

After that, screw the hook into the dowel, or install the expansion anchor and hang the chandelier. The wires of the chandelier are connected to the wires coming from using a special block equipped with clamping bolts (sometimes this block is called a terminal block). It is for tightening the bolts of this block that you will need a slotted screwdriver with a narrow sting. The box comes with a chandelier. If it is not there, they are twisted and insulated with insulating tape. It would be better, of course, solder the twists, but you can do without it, especially when using energy-saving lamps. Move the decorative "cup" close to the ceiling, and fix it.

How to hang a chandelier with a decorative strip

A chandelier is a little more difficult to hang with a metal bar. The bar is applied to the ceiling at the location of the chandelier. With a pencil or a thin marker, mark the places for drilling holes for dowels. Having removed the bar, drill holes and drive dowels into them. The fixing bolts are inserted into the bar, they are moved apart by a distance corresponding to the distance between the holes in the decorative lining of the chandelier, and so that they do not move, they are clamped with nuts.

Then, the bar is placed on the ceiling, screwing it with screws. Next, the most difficult part of the work, which is best done with an assistant. The decorative box must be attached to the ceiling above the bar in such a way that the exposed bolts fall into the holes in the box. Before that, connect the wires of the chandelier and. To make it more comfortable, stand as high as possible. When performing these operations, the assistant must hold the chandelier (you will not connect the wires with one hand). When the bolts match the holes, the decorative box is pressed against the ceiling and clamped with decorative nuts.

Most apartments in high-rise buildings cannot boast high ceilings. The use of tension or suspension structures here should be approached very carefully, since they eat up such necessary centimeters. Very often the surface of the floor slabs is leveled and whitewashed or painted. When thinking about lighting issues in such rooms, you need to think about how to hang the lamp on a concrete ceiling and fix it correctly.

There are a lot of fasteners and various brackets now, for mounting ceiling lighting you can use:

anchor hook;
Clamping suspension;
Overlay fastening.

The easiest and most reliable option to hang a chandelier is an anchor hook screwed into the ceiling. It allows you to hang large massive chandeliers from concrete ceilings. Installing the anchor on a hollow slab is associated with some difficulties. It may happen that the drilled mounting hole will fall into the internal cavity. In this case, the reliability of fastening will significantly decrease, since only half of the estimated length of the hull will work for thrust. The way out of this situation is simple - move a little to the side and drill a new hole, and cover the old one with putty.

The clamping hanger is designed just for installation on hollow core slabs. Due to the simplicity and efficiency of the design, it is he who is most often installed in new buildings. And since its reliability is very high, most residents are not even aware of its existence. Its bearing capacity is somewhat lower than that of the anchor, but still quite sufficient to hang a chandelier weighing up to 5-7 kg.

Butterfly montage

Installing an auxiliary overhead strip on the ceiling allows you to mount the luminaire when for some reason the installation of an anchor or suspension hook is impossible or undesirable. Another reason to use this installation method is the standard chandelier mounting system. There is no need to reinvent the wheel when all the necessary parts are supplied with the lamp and the only thing left is to assemble them.

List of materials and tools required for work

In the vast majority of cases, everything that may be needed in order to hang a lamp is already in the arsenal of a home master:

A drill inserted into a perforator chuck is an almost uncontested option for hassle-free work with concrete;
A set of wrenches will help to cope with the tightening of the anchor hook or nuts on threaded studs with an overhead mounting method;
Wire insulation is stripped using a sharp knife;
Terminal connectors are used for switching contacts;
A screwdriver is necessary for the screw method of fixing the wires;
To seal the electrical wiring entry points, it may be necessary to use fire-resistant mounting foam or mineral wool, followed by a layer of putty flush with the ceiling surface.

Instruments

Ceiling hook installation

The installation process of anchor fastening is quite simple and does not require lengthy explanations. At the selected point on the ceiling, a hole of the required depth and diameter is drilled. A metal anchor is inserted into it and twisted first by hand, and then with the help of wrench hook on which you can then hang the lamp.

Anchor bolt mount

To protect the puncher from getting dust, sand and small concrete chips on the drill, you can put on a disposable cup made of thick paper. On the one hand, the installation of a suspension suspension is simpler, since there is no need to drill the ceiling, and on the other hand, it is somewhat more complicated and requires some explanation. Due to the specifics of its design, this fastening can only be used on hollow concrete floors. A spacer rod 10-15 cm long and up to 3-5 mm in diameter is inserted into the inlet in the slab and pushed into the internal cavity.

The next step to be completed is the installation of the suspension bar. This is a narrow metal plate, on one end of which a series of holes is made, on the other a small hook is formed, on which you can hang a chandelier. The plank is taken in one hand and placed inside the concrete slab. With the other hand, the spacer rod is threaded through one of the holes. The closer it is to the edge of the plate, the greater the distance from the ceiling to the hanging hook. Thus, you can adjust the protrusion of the suspension by 3-5 cm.

Next, the mounting ends of the chandelier are connected to the electrical wiring. Completes the entire assembly process installation close to the plastic ceiling decorative overlay. Due to the presence of a slot, it is put on a hanging bar, fixing its position and completely blocking the hole in the concrete slab.

Installing the overlay

Installing some kind of auxiliary support surface is the most versatile method. An overlay for hanging is usually supplied with a chandelier, but if necessary, you can make it yourself or choose a suitable bracket from the range of the nearest hardware store. The meaning of this installation method is to disperse the attachment points to the ceiling.

cruciform plank

As standard, the overlay bar can be made as a cross or a single narrow metal plate. Fastening to the ceiling surface is carried out by four or two dowel-nails. The chandelier is directly fixed with the help of decorative union nuts screwed onto threaded studs welded to the plate.

If for some reason the standard mount is not suitable for mounting, you can use perforated mounting brackets of suitable size or make a metal plate that is suitable in size and make all the necessary holes on it. Instead of welding threaded studs, a screw-nut connection can be successfully used. Further, the sequence of installation of the lamp completely coincides with the factory version.

Sealing the wiring entry

standard input electric wire to connect the lighting, it is carried out in the middle of the room through a hole in the ceiling with a diameter of 5-7 cm. In a concrete slab inside the cavities, during the construction of the house, the cable is forwarded to the switch and connected to the general network. Sealing of these channels is most often not performed and sounds and smells from neighboring rooms easily spread through them. Replacing the chandelier is a very good reason to eliminate this shortcoming.

Hole in concrete

The easiest option to foam everything free space inside fire resistant mounting foam. However, the apparent ease of the solution can then bring a number of problems if you need to hang another lamp. To get to the connection terminals, you will have to work very well with a knife, cutting out the cured polyurethane foam in small pieces. Using mineral wool all free space is densely filled with small pieces of this non-combustible insulation. The fastening of the material inside the plate is carried out due to the high elasticity of the fibers. Compressed cotton wool, straightening inside the hole, performs its complete sealing.

To finally isolate the room from extraneous odors and sounds, the surface is puttied. A gray reinforced tape is glued over the cotton wool with a small entry to the ceiling (up to 5 cm). Then a sickle masking tape is attached to it, which will ensure the necessary adhesion of the solution to the surface. The final step is to apply and level a thin layer of finishing putty.

Electrical safety issues

As with all matters relating to the connection of household electrical appliances, the installation of a chandelier on a concrete ceiling must be carried out taking into account the requirements of the current regulatory documentation. Before drilling mounting holes, it is advisable to check the location of the wiring. For these purposes, you can use a universal tester or locator. When the probe hits electric field the device will give sound signal. Of course, there will not be a 100% guarantee, but the probability of damaging the supply wire with a drill will decrease many times over.

During the installation process, a situation often arises when it is necessary to connect the copper wires of the lamp with the old aluminum wiring. In this case, switching issues should be approached with special attention, since poorly made contact between these two metals is a source of increased danger and can cause a fire.

Aluminium-copper tips

It is absolutely not permissible to connect copper and aluminum wires using twist. For the most reliable switching, it is necessary to use terminal clamps (preferably those that use screw fastening). Single-core conductors are stripped of insulation, inserted into the connectors and fixed. For a stranded copper wire, it is necessary to perform an additional operation of tinning the mounting end to fasten the individual wires into a single monolith and ensure reliable electrical contact between them.

As you can see, to hang a chandelier on a concrete ceiling, there is no need to use complex fixtures and tools. If necessary, instead of standard factory mounts, you can make your own or pick up their analogues. The most important thing, as in any work, is accuracy, lack of haste and compliance with safety regulations.
