How to hang a chandelier from the ceiling: different mounting methods for different occasions. How to hang a chandelier on a concrete ceiling yourself? How to hang a chandelier on a concrete ceiling

When the question arises of how to hang a chandelier on the ceiling, many developers think that this process is complicated and should only be performed by professionals. In fact, there is nothing complicated in the work, and even an inexperienced master can understand the process. I will tell you about all the important aspects so that you can carry out high-quality installation without outside help.

The working process

First, I will talk about how to deal with the electrical part, it is the same in all cases, and then I will consider in detail the 4 mounting options that are used most often. Safety is important in electrical work, so be sure to carefully follow all recommendations in the next section.

Connecting wires

If you doubt that you can handle electrical work, it is better to involve a specialist, but if you have at least minimal knowledge and skills, then you can handle the work process yourself.

Let's figure out what you need to have on hand:

• To work we need an indicator, this is the name of a special tool with which you can determine the phasing of wires, that is, figure out where the voltage is in order to correctly connect the switch;

• In order to securely and safely fasten the wires, we need special connectors. The time of electrical tape and twists is long gone; it is better to purchase standard terminals or modern self-clamping options in order to fasten the wiring not only very quickly, but also very reliably. You can buy such elements at any electrical store;

• We also cannot do without a screwdriver, pliers and a construction knife. These tools are used most often during work, and such a simple set is quite enough to cope with the installation efficiently.

Let's figure out how to properly connect the wiring, the process is the same for all types of fastening, so I'll look at it here, and below I'll specifically deal with fasteners.

The workflow looks like this:

• First, you need to turn off the current supply in the electrical panel; in new houses there is a special machine; in old houses you need to unscrew the plugs. That is, we de-energize the network to prevent electric shock;
• If you had an old chandelier, then you need to remove and disconnect it, sometimes this process takes longer than installation, once I tore out a structure nailed to a beam with nails 150 mm long, probably there were no shorter products at the time of fastening;
• Then you should strip the ends of the wires that are connected to the chandelier and move them apart so that they do not touch each other in any way. The cleared areas must have free access from any side;
• The power is turned on on the panel and the wires are checked. This is done like this: first, the switch is placed in the “on” position, then the indicator is taken in the right hand, the thumb is placed on the patch at the end, and the probe is pressed to the end of the wire on the ceiling. Where there is a phase, the indicator will light up, where there is no phase, nothing will light up;

• You need to check the circuit again with the light off; naturally, there should be no current in this case. If it is, then the switch needs to be replaced.

When checking the current, work with one hand; holding the wire with the other hand, even by an insulated area, is strictly prohibited.

• When you have figured out the wires, you can start connecting; with a chandelier, most often there is a diagram, everything is shown there clearly. As an example, below is a diagram with the connection of a two-key switch, everything is very simple and clear, the main thing is not to confuse anything;

• When you understand the circuit, you can connect the wires; to do this, place a terminal or a special connector at the connection point. Everything is simple here, and the main thing is to securely fix the wires; under no circumstances should they dangle at the connection point.

Fastening option No. 1 – anchor bolt with hook

This is a classic solution, which, in my opinion, is the simplest and most reliable. The anchors are suitable for concrete ceilings and are used for chandeliers that are suspended from a special eye. Below is shown what this fastening element looks like; anchors with a diameter of 10 mm and a length of the working part of 50-80 mm are most often used; this is quite enough to withstand a load of even tens of kilograms.

Let's figure out how to attach a chandelier to the ceiling using anchors with a hook:

• First of all, you need to stock up on the required tools; we will use a hammer drill with a drill of the appropriate diameter. It is worth working from a ladder or table; it is important to ensure stability, since working with a hammer drill requires some effort, and you must stand securely;
• Next, the drilling location is marked on the ceiling surface; it should be positioned so that the decorative part of the chandelier covers the place where the wires are attached and connected;
• Drilling is carried out 10 mm larger than the working part of the anchor, this is necessary for its reliable location in the ceiling. When working, make sure that the hammer drill is positioned vertically;
• An anchor bolt with a hook is inserted into the hole until it stops, after which it needs to be tightened. There can be two options: either you twist the hook with your hands and, as a result, the sleeve inside expands, or you need to twist the nut, which is available in some product versions. The work flow diagram is shown below - everything is very simple and clear;

• Lastly, the chandelier wires are connected and it is hung on a hook. At this stage, it is better to involve an assistant, since you are unlikely to be able to hold the structure and connect the wires. After hanging, the attachment point is covered with a cap, which is fixed in the required position.

If you have wooden floors, you can use a hook screw rather than an anchor bolt. Its installation is similar to that described above, with the only difference being that you need to drill a hole 2-3 mm smaller than the diameter of the fastener, and then screw it in like a screw. Very simple and at the same time reliable.

Option No. 2 – mounting plate

This type of fastener is used in most modern chandeliers; the kit includes a special plate with two threaded rods and several holes for fixing to the ceiling. The system is simple, but quite reliable, which is why it has gained such high popularity.

For massive products, a reinforced version is used - a cross-shaped design, which allows you to fix the chandelier at four points. Such a system can even withstand a lot of weight, so it is used with heavy chandeliers.

Let's figure out how to install a chandelier on a plate.

The work instructions look something like this:

• To work, in addition to the bracket itself, we will need fasteners; for concrete ceilings, quick-installation dowels 6x40 are used, and for wooden structures, self-tapping screws 30-40 mm long are used. Drilling is done using a hammer drill, which can be rented; you only need it for half an hour;
• The plate is placed in the place you require, after which, using a pencil, you need to mark the points at which drilling will be done. It is important to place the element correctly so that the structure is held securely and the wires reach the connection point;
• Drilling is done at the marked points; a standard plate requires two holes, and a cross-shaped plate requires four. The work is simple, the main thing is to hold the hammer vertically and control the depth, it should be 5 mm greater than the length of the dowels used;

• Next, you need to fix the bracket; to do this, dowels are driven into the holes, after which the plate is attached and secured using self-tapping screws or impact screws. They do not need to be tightened - they are driven in with a hammer. After fastening, check the reliability of the fixation; there should be no play;

• The chandelier is connected using terminals; this process is described above, so there is no point in dwelling on it;

• Lastly, the chandelier is put in place and secured with nuts and washers that are screwed onto the studs. The mounting hardware is included, so there is no need to purchase anything additional.

Option No. 3 – dowels for hollow structures

If you have a plasterboard ceiling or need to fix the chandelier in a hollow slab, then the best option may be a special dowel, which is a spacer on one side and a hook on the other.

Let's figure out how to hang a chandelier with your own hands using this mounting option:

• First, you need to mark the point where the dowel will be located; if the work is done on a plasterboard structure, then there is not much difference, but if you are dealing with a reinforced concrete slab, then you need to calculate the location of the void. Sometimes you have to make several holes until you get where you need to;
• Then drilling is done, everything is simple, the main thing is to have on hand a tool with a drill of the appropriate diameter (most often it is 10 mm). Drywall can be drilled using any equipment; for concrete you need a special drill;
• The spring part of the dowel is compressed with your fingers, after which it must be inserted into the hole and lifted up so that the spacers move apart and fix the fastener in the void. Everything is simple here, and you can easily figure out this part of the workflow;
• Lastly, you need to fix the fastener in the hole; to do this, you need to tighten the threaded part using a nut, under which an oversized washer should be located. The whole process from start to finish is shown in the diagram below, you will clearly see all the stages and make sure that everything is simple;

• Further work does not differ from the options described above: you must first connect the wiring and then hang the chandelier on a hook. Everything is done in the same way as in the case of an anchor bolt.

I would like to talk about the fastening options that are used when mounting a chandelier on a plate; in this case, you can use several types of products; for convenience, I will present the information in the table.

Remember that if the weight of the chandelier is very large, then the drywall simply will not withstand the load, even the strongest dowels will not help. In this case, you need to drill a hole in the concrete and secure the structure with long anchor bolts.

Option No. 4 – installation on a platform

This type of structure is in great demand due to the fact that it is used in conjunction with stretch ceilings, which are gaining increasing popularity. To hang a chandelier, you need to build a special structure called a platform; the essence of the installation is shown in the diagram below.

Let's figure out how to hang a chandelier in this case:

• You can adapt a piece or boards of a certain size, but it is much easier to buy a ready-made platform, which has a hole for the wire and holes for mounting around the entire perimeter. Of course, a self-tapping screw can be screwed into any place, because plastic is easy to process. The products have a standard diameter of 180 mm, but if desired, you can find a larger option;

• First you need to clearly determine the level of the stretch ceiling; this is very important, because the platform must be located strictly along the plane of the canvas. It is best to pull the cord so that you can clearly see the landmark and not make mistakes when carrying out work;
• Four straight drywall hangers are attached to the platform. If the length of the fasteners is too long for you, then you can cut the hangers into pieces of the required size. The easiest way to assemble the structure is to use sharp bugs - small self-tapping screws for metal profiles; in the end you should get something like the one in the photo below;

• Next, you need to determine the location of the platform on the ceiling, after which you can begin mounting. The structure is set to the required level, and the hangers, if necessary, are bent to the required position. Installation is carried out using quick installation dowels.

Attaching the chandelier to the ceiling

When purchasing a new chandelier, the question of its correct and reliable attachment to the ceiling surface, as well as its safe and correct connection to the home’s electrical network, becomes relevant. This can be done without outside help, so arm yourself with the necessary tools for installation, read our instructions and proceed with installation.

This article will discuss how to attach a chandelier to the ceiling with your own hands.

Attaching the chandelier using a mounting strip

As a rule, chandeliers come in two types:

• Equipped with a fastening strip. The bar is mounted on the ceiling, and then the chandelier is attached directly to it.
• Attached to a ceiling hook that is securely screwed into the ceiling. We will try to cover in more detail how to attach a chandelier to the ceiling surface, using each of the indicated methods.

Advice! Before installing the chandelier to the ceiling, remove the shades and other decorative elements of the chandelier. This will protect them from accidental damage, reduce the weight of the chandelier and make installation more convenient.

Mounting the mounting strip

Fastening the ceiling chandelier begins with installing the fastening strip to the surface:

1. First, try on the chandelier to the place where it is supposed to be mounted in the future.. The decorative element of the chandelier, covering the mounting point and wires, must fit tightly, without gaps or play, to the ceiling.
2. If there is a hook from an old lamp at the installation site, bend it to the ceiling so that it does not interfere. It is not recommended to cut off the old hook, since your next chandelier may be mounted using it, and you will need to re-install this type of fastener, which is impractical.
3. Make markings for attaching the mounting strip and install fasteners for the chandelier on the surface. To do this, apply the strip to the ceiling in such a way that it does not interfere with the wiring connection, and use a pencil to mark the mounting location. Next, drill holes and drive dowels into them. Then attach the plank to the ceiling using screws(read on).

Connecting electrical wiring

Before attaching the chandelier to the ceiling surface, it is necessary to connect the power supply wires provided in it to the power system of the house. Before connecting the chandelier, it is imperative to turn off the power to the house wiring and make sure there is no voltage using an indicator.

The rules for connecting a chandelier to the electrical network are as follows:

• If there is a single-key switch, the ceiling wiring under the chandelier usually consists of two or three wires - phase, neutral and optionally a ground wire. The presence of a grounding wire often depends on the time the house was built - in Soviet times such a wire was provided extremely rarely.
• It is necessary to determine the purpose of each wire, both among the ceiling ones and among those available in the chandelier. The phase wire is usually hidden in black, brown or red insulation, the neutral wire in blue, and the ground wire in yellow-green.

• Regardless of the presence of color or other markings on the wires in the ceiling, they should be tested with an indicator screwdriver. To do this, you will need to turn on the current supply for a while. You should touch the exposed part of the wires one by one and record the indicator value. The indicator that lights up will indicate the phase wire; if the indicator does not light up, it means the wire is neutral.

Advice! Do not forget to press the light switch keys on the switch before checking the wires with the indicator.

• Wires of the same type are connected through terminals, and if there is a wire “without a pair” (grounding), it is isolated and moved to the side. After this, you can continue further attaching the chandelier to the ceiling.
• A two-key switch assumes the presence of two-phase wires in the ceiling (see). They are connected respectively to the phase wires of the chandelier of the 1st and 2nd groups (if any). The neutral and ground wires are connected in the same way as in the first case.

Attaching the chandelier to the mounting strip

You can do this in the following way:

1. The closing decorative element of the chandelier is placed against the bar and their connecting holes are matched.
2. Screw decorative nuts into the holes, thereby finally attaching the lighting fixture to the ceiling.
3. Lamps, shades and other decorative elements are mounted in their original place.

Attaching the chandelier to the ceiling surface in this way can be considered complete.

Attaching a chandelier using a ceiling hook

Such a mount for a ceiling chandelier, like a hook, is often installed during the construction of a house, and if you have one, you should check its strength. Testing a hook involves trying to tear it off. To do this, you can tug on it or hang a load comparable in weight to or greater than the weight of the chandelier, and let it hang for some time.

If the hook is firmly secured, you can attach the chandelier to the concrete ceiling covering.

If it falls out or is simply not provided for on the ceiling, you will need to mount it yourself:

1. Drill a hole for it.
2. Prepare and screw a metal anchor into the hole. It must be selected with such a diameter that it fits snugly against the walls of the hole during the screwing process.
3. For installation in a wooden ceiling, you can use a self-tapping hook.
4. When installing a chandelier on a plasterboard ceiling, the hook must be attached to the ceiling. The distance between the main and plasterboard ceilings is overcome by hanging a chain on a hook equal to the length of the gap between the ceilings. It is to the chain that the ceiling chandelier is later attached.

Advice! The metal hook must be carefully insulated for safety reasons.

We can assume that we have figured out how to mount various types of chandeliers. We hope that our instructions turned out to be easy to understand, and with an eye on them, you will be able to install the chandelier with your own hands without any problems.

For those who do not fully understand all the intricacies of the installation process, we recommend that you familiarize yourself with the video presented on our portal - how to attach a chandelier to the ceiling.

The choice of lighting fixtures plays an important role in creating comfort and beauty at home. Having bought a lamp for home, another important question arises before the user - how to hang a purchased chandelier yourself so as not to damage the ceiling and place the product correctly.
Today, there are two main types of mounts that are suitable for a variety of device designs. The choice of mounting method also depends on the type of ceiling.

Attaching the chandelier to a hook

Hook- an old and reliable method of attaching lamps to the ceiling. Almost all Soviet apartments, in every room, have such a mount. If the room where you plan to hang the lamp already has fasteners, then placing the product on it will not be difficult.

In order to check the reliability of the hook, it is necessary to hang a load on it, the weight of which corresponds to the selected chandelier. If within 24 hours the hook does not fall out or become deformed, then it is suitable for attaching a product to it.

If there is no hook, but there is still a drilled hole in the ceiling, you can screw in a new fastener. Its choice must be approached with special care - it must be screwed tightly into the ceiling, there should be no gaps left. The choice of size and type of hook depends on the design and weight of the chandelier. If the user decides to choose a new place to place the chandelier, then the hook can be screwed in independently. In this case, you should pay attention to the fact that electrical wiring runs nearby.

If the lamp mount does not reach the hook, you can hang an additional chain.

In hardware stores you can find a hook - a self-tapping screw, which is suitable exclusively for attaching it to wooden ceilings. For other types of ceilings, you will first need to drill a hole and then screw the hook into it.

Bar mount

Plank– universal mounting method. It allows you to place heavy structures with many elements on the ceiling. You can also use the strip to hang an oversized chandelier.
The plank is an aluminum profile that is attached to the ceiling using self-tapping screws.

The bar can have different lengths and widths depending on the weight and dimensions of the selected lamp.

If the lamp is too large, the bracket can be shaped in the shape of a square or rectangle. This fastening method evenly distributes the load from the weight of the product and is more reliable in use.
The plank can also be mounted in the shape of a cross or a “snowflake”.

How to hang a chandelier on a bar:

1. Initially, you need to choose the place where the lamp will be placed. The choice of location must be taken with special attention so as not to damage the wiring running along the ceiling.
2. The selected places must be marked. At the marked places, holes are drilled using a drill, into which dowels are inserted and screws are screwed in.
3. The chandelier is attached to the attached strip and the wires are connected.

The bar allows you to mount any type of lamps, even those that have a high mass. This method is considered the most reliable, since it is convenient when changing light bulbs - the chandelier does not scroll. While fastening with a hook causes certain difficulties in the future.
Thus, there are several ways to attach a chandelier, which differ in the way the work is carried out. The choice of installation method depends on the type of lamp, the design solutions in the interior, as well as the personal preferences of the owners of the room.

Features of ceilings

In order for the purchased chandelier to please its owners for many years and not collapse due to the unreliability of the mounting method, you need to pay attention to the fact that each ceiling can withstand different weight loads. In addition, certain ceilings will require special work methods and construction materials.

Mounting a chandelier on drywall

Drywall is often used when installing ceilings. Due to the lightness of the material, plasterboard allows you to create ceilings of fancy shapes. However, drywall is an extremely thin material and is unable to withstand high weight.

A chandelier weighing no more than 2 kilograms can be attached to drywall. Otherwise, the chandelier and ceiling may collapse.

If the weight of the lamp does not exceed 2 kilograms, to attach the chandelier you will need a special type of dowel - a butterfly. Butterfly dowel is a fastener that looks like a regular metal dowel, but when inserted into the interceiling space, it opens and is securely fastened. Such fasteners are sometimes initially equipped with a hook, so hanging the chandelier will not create any difficulties.

When working with plasterboard, it is taken into account that the dowel must extend into the ceiling by at least 15 cm. In addition, the ceiling is equipped with a special non-conductive bushing for safe cable exit.

It is allowed to mount an aluminum strip on drywall if the chandelier is large. The method of attaching the strip is no different from those described above.
If the weight of the lamp exceeds the norm, you will need to create a special mount. So, a round hole is drilled in the ceiling. After this, a strip is mounted directly to the concrete or tiled base, onto which the chandelier is attached.
Upon completion of the work, the hole in the ceiling is masked with the help of decorative elements (these could be elements of a chandelier).

How to hang a chandelier on a suspended ceiling

A suspended ceiling, despite all its positive qualities, is extremely inconvenient to install lamps on it. The fact is that fastening the lamp directly to the tension fabric will immediately lead to sagging of the latter and a possible breakthrough at the place where the fasteners are installed.

To attach a chandelier to a suspended ceiling, all work should be carried out until the film is tensioned.

So, a hook or plank is attached to the base of the ceiling. The method of fastening is no different from the procedure described above. After this, the ceiling film is tensioned. A mark is made in the place where the chandelier is expected to be placed. Next, you need to cut a hole that will be sufficient in diameter to mount the lamp.
To ensure that the edges of the hole on the film do not separate, it is necessary to mount a special plastic circle that will hold the edges of the film and prevent it from sagging. The film is also stretched in this circle and the pins for attaching the chandelier are pulled out through it.

Working with electricity

In addition to installing fasteners to the ceiling, it is also necessary to properly connect the lamp to electricity. To do this, you should strictly follow the instructions written in the chandelier's passport. If you connect the lamp incorrectly, it will cause malfunctions not only in its operation, but also create a great danger for the residents of the house.

When choosing a chandelier, in addition to external qualities, pay attention to the power and amount of electricity consumed. Otherwise, the electrical wiring of the apartment may not withstand such a load.

Before connecting the light fixture, you should understand the variety of wires that will power the lamp. The network runs on alternating current, with a voltage of 220 V and a frequency of 50 Hz. The current passes through 2 cables - phase and zero. In some rooms there is a third cable - grounding. Decide on the purpose of each wire easy enough:

• the “phase” wire has a golden color;
• “zero” is colored blue;
• The ground cable is bright yellow.

Please note that this color scheme was adopted relatively recently; old buildings retained the same type of color scheme, so you will have to figure it out yourself.

In the case when a lamp with several keys is connected to the room, there will be several phase wires.
Before starting work, you need to turn off the electricity in the house and you can get started.
For work you will need the following tools:

• pliers (for cable preparation);
• insulating tape;
• blowtorch;
• distribution box or terminal block;
• multitester (to determine the type of wires).

Connecting lamps that are equipped with one row of horns and connected to a single-key switch is not difficult. To do this, we find the phase and neutral cables and combine them with the electrical wiring on the ceiling. On modern chandeliers, these cables are painted in special colors or marked in another way.

It is more difficult to connect chandeliers that have two or more groups of arms (rows). In this case, groups of wires are connected. So, initially you need to find all the phase wires and connect them through a terminal block or junction box, and then connect them to the main wire on the ceiling. The same operation should be performed with the neutral wires.
Terminal block– a product that is designed to connect wires of the same type.
Thus, hanging a chandelier yourself is not so difficult; to do this, it will be enough to follow the proposed instructions and the rules for operating electrical appliances.
If any difficulties arise during installation or connection of the chandelier, it is better to contact the services of specialists to avoid possible problems.

Most apartments in multi-storey buildings cannot boast of high ceilings. The use of tension or suspended 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 covered with whitewash or painted. When thinking about lighting issues in such rooms, you need to think about how to hang a lamp on a concrete ceiling and secure it correctly.

Nowadays there are a lot of fasteners and various brackets; to install ceiling lighting you can use:

• Anchor hook;
• Clamp suspension;
• Overhead mount.

The easiest and most reliable option for hanging a chandelier is an anchor hook screwed into the ceiling. It allows you to hang large massive chandeliers from concrete floors. Installing an anchor on a hollow slab presents some challenges. It may happen that the drilled mounting hole falls into the internal cavity. In this case, the reliability of the fastening will be significantly reduced, since only half of the design length of the body will work against the 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.

Attaching a chandelier to an anchor hook

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

Installing an auxiliary overhead strip on the ceiling allows you to mount the lamp when, for some reason, installing 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 to hang a lamp is already in the arsenal of a home craftsman:

• A drill inserted into a hammer drill chuck is practically the only option for trouble-free work with concrete;
• A set of wrenches will help to cope with tightening the anchor hook or nuts on threaded rods with the overhead fastening method;
• Stripping the wire insulation is done using a sharp knife;
• Terminal connectors are used for switching contacts;
• A screwdriver is necessary for the screw method of fixing wires;
• To seal the electrical wiring entry points, you may need fire-resistant foam or mineral wool, followed by a layer of putty flush with the ceiling surface.

Ceiling Hook Installation

The process of installing anchors is quite simple and does not require extensive explanation. A hole of the required depth and diameter is drilled at a selected point on the ceiling. A metal anchor is inserted into it and first screwed in by hand, and then using a wrench, the hook is screwed onto which the lamp can then be hung.

To protect the hammer drill from dust, sand and small concrete chips, you can put a disposable cup made of thick paper on the drill. Installation of a clamping suspension, on the one hand, is simpler, since there is no need to drill the ceiling, but 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 hole in the slab and pushed into the internal cavity.

The next step to complete is installing the hanging strip. This is a narrow metal plate, at one end of which there is a series of holes, at the other end there is a small hook 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 located to the edge of the plate, the greater the distance from the ceiling to the hanging hook. This way you can adjust the suspension protrusion by 3-5 cm.

Next, the mounting ends of the chandelier are connected to the electrical wiring. The entire assembly process is completed by installing a plastic decorative lining close to the ceiling. Due to the presence of a slot, it fits onto the hanging bar, fixing its position and completely covering the hole in the concrete slab.

Installation of the trim strip

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

As standard, the overlay strip can be made as a cross or a single narrow metal plate. Fastening to the ceiling surface is carried out using four or two dowel nails. The chandelier is directly fixed using decorative cap nuts that are screwed onto threaded rods welded to the plate.

If for some reason the standard fastening is not suitable for installation, you can use perforated mounting brackets of suitable size or make your own metal plate of suitable dimensions and make all the necessary holes on it. Instead of welding threaded rods, you can successfully use a screw-nut connection. Next, the installation sequence of the lamp completely coincides with the factory version.

Sealing the wiring entry

The standard entry of an electric wire for connecting lighting 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 a house, the cable is routed to the switch and connected to the general network. These channels are most often not sealed and sounds and odors from neighboring rooms easily spread through them. Replacing a chandelier is a very good reason to eliminate this drawback.

The easiest option is to foam all the free space inside with fire-resistant polyurethane foam. However, the apparent ease of the solution can later 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 hardened polyurethane foam in small pieces. When using mineral wool, all free space is tightly filled with small pieces of this non-combustible insulation. The material is fastened inside the slab due to the high elasticity of the fibers. The compressed cotton wool, straightening inside the hole, completely seals it.

To completely isolate the room from extraneous odors and sounds, the surface is puttied. Gray reinforced tape is glued over the cotton wool with a slight extension to the ceiling (up to 5 cm). Then serpyanka 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 in 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 current regulatory documentation. Before drilling mounting holes, it is advisable to check the wiring location. For these purposes, you can use a universal tester or locator. When the probe enters an electric field, the device will emit a sound signal. Of course, there will not be a 100% guarantee, but the likelihood of damaging the supply wire with a drill will be reduced 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 executed contact of these two metals is a source of increased danger and can cause a fire.

It is absolutely not permissible to connect copper and aluminum wires by twisting. 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 connectors and secured.
