Connecting the construction trailer to electricity. How to connect a change house to electricity, how to make internal wiring

Installing change houses in our time is not uncommon, since it is an affordable and convenient option for temporary housing or inventory storage. In this regard, an urgent question arises: how to make an electrical project for them?

The change house is not classified as an object of construction in progress, therefore, the connection of electricity is officially considered intermittent (for some time), but, despite this, it has an unlimited period of use.

What do you need to connect?

The wiring of electricity to a change house and to a private house is slightly different. In the first case, the cable is pulled through the air. It is not recommended to do this on your own, as this will lead to undesirable consequences. The owner of the change house will be brought to administrative responsibility.

Internal wiring has its own characteristics that need to be taken into account. In order for “light” to appear in the change house, it is necessary:

• 2 sockets;
• 1 switch;
• a lamp powered by electricity or a lamp;
• wire boxes;
• fuses that prevent short circuits;
• wiring.

How is the process going?

When everything you need is purchased, a scheme is created according to which the wiring will be performed. Then they start the process itself. The wires are attached to the walls without any preliminary work in plastic cable channels. In order to improve fire safety, you can replace them with metal counterparts. After the channels are fixed according to the scheme, cables are laid inside. The thickness of the guides is chosen according to the type of wire. It is advisable not to fill them too tightly, but leave some free space.

You also need to take care of outdoor lighting. Power for it can be thrown from the internal wiring. If the presentable appearance of the change house premises has great importance, then the cable channel must be chosen in the same color as the wall decoration.

When buying cables, you must take the length with a margin. After everything is fixed and all channels are closed, the process of conducting electricity can be considered completed.

The amount of materials needed for this may vary depending on the size of the change house and the requirements for it. In most cases, internal and conventional wiring — they are different services. In the latter option, you can throw it through the air or along the trench, but it will come out much more expensive.

Today, projects of houses with a bath or sauna are especially popular, since in this case it is not necessary to allocate a plot of land for the construction of another object. In addition, combining a sauna with a home can significantly reduce installation costs, because in this case only additional thermal insulation works, installation of equipment and quality ventilation system.

Seam metal roof with a double standing seam and solid paintings is currently the most reliable roofing option. As a species, it has been known for a long time. In Europe, seam copper roofing was used for town halls and cathedrals. Compared to a single fold, a double fold was more reliable, but it was more difficult to perform, in connection with this, during the USSR from its use ...

These locks are most often calculated on a layer of material 1.6-1.8 centimeters, in some cases - 2.2-2.4 centimeters. They are mounted like this. A hole is made under the larva, on the back of which the lock body is mounted. The hole for the larva from the outside is closed with decorative strips. Furniture locks designed for hinged doors and boxes made of wood and chipboard. Furniture lock,…

The Change Houses 116 company is engaged in the production of construction and country change houses, as well as turnkey panel houses. At the same time, in each building we produce, we lay functional and safe electrical wiring in accordance with the requirements of the PUE. This article will be useful to you if you have bought change house or the house is not with us, or they built it themselves and want to conduct electrical wiring. In the article we will consider a scheme involving the installation of the following elements:
- circuit breaker;
- connecting box;
- lamp;
- switch;
- electric outlet;
- pencil cases or corrugated tubes;
- electric wires.

The circuit breaker is designed to protect electrical wiring in a house or country house. It works in case short circuit, or in case of exceeding permissible load, that is, when there is a possibility of heating electrical wires. The point is that when designing electrical wiring, the maximum possible electrical load must be taken into account. Depending on the load, the material and the cross-sectional area of ​​​​the wires in the change house are selected. After that, the machine is selected. If you choose an automaton for currents greater than those for which the wires are designed, then when creating a certain electrical load, in change house a fire may occur.

Choice of electrical elements.

All wire connections must be made through terminal blocks, which in turn must be hidden in electrical boxes(see photo 1).

Table 1. Selection of the cross-section of a copper stranded wire

Since the change house sockets will be used to connect electric tool, for them you need to choose electrical wires with the largest possible cross section. If it is supposed to hang on sockets no more than 3.7 kW, then for sockets in change house a wire with a cross section of 1.5 mm2, rated for 5 kW, is selected. Such a conductor can withstand a current of 23 A, so you need to set electric machine for a smaller current - 20 A. For a lamp, you can safely use conductors with a cross section of 0.5 mm2. The wire is designed for a load of 2.4 kW. That is, even installing a 150 W (0.15 kW) light bulb will not create a load on the wire. However, we recommend using energy-saving lamps because they will not heat up the socket and interior material of the cabin.

Wiring diagram in the change house is shown in diagram 1.

After buying all necessary components our electrical wiring, in the change house it is necessary to install sockets, a lamp and a switch in convenient places. The socket should be at a height of approximately 1-1.5 m, it should not be blocked by a cabinet or other furniture. The switch should also be close at hand so that it can be easily found in the dark. Next, the canisters are screwed, the wires are laid and connected.

Wires to the trailer or switchboard house of the change house are usually pulled through the air. Direct installation inside will be specific, the wiring in the change house is distinguished by some features that must be taken into account. Usually, for the electrification of a change house you will have enough:
- two ordinary sockets (or two blocks of two sockets)
- one switch.
- an electric lamp or a lamp (naturally, quite simple, suitable for a temporary structure).
- junction box for wires.
- a fuse to prevent short circuit.
- actual wiring.
Wiring mounted external way, after the final determination of the layout of the electrical points and the lamp. The wiring is attached directly to the walls, without preliminary work, in plastic cable channels or corrugated pipes. For increase fire safety metal analogs can be used. After fixing the channels or corrugated pipes in accordance with the scheme, cables are laid inside. The thickness of the guides depends on the type of wires under which they are installed. Too dense filling is not recommended, there should be some more space in the guides.
Take care of the little things, not only inside, but also outside the change house. Be sure to install street lighting, it can be powered from internal wiring.

If it's important to keep appearance interior, then it is worth choosing a cable channel that matches in color with interior decoration. In any case, when purchasing the cables themselves and the guides for them, you need to take the length with a small margin. After laying the cables and closing the channels, the wiring in the change house can be considered completed. Of course, the described manipulations are very schematic and represent minimum set, which may vary due to different equipment of your technical room.

Many have a change house in their summer cottage. It can be used for different purposes. If desired, it can conduct electricity. However, this will require the permission of the partnership to which the personal plot is assigned.

On the site www.skblok.ru you can purchase affordable and comfortable country change houses from the SK Blok company.

According to the regulatory legal norms, a change house cannot under any circumstances be considered an object of capital construction. That is, the connection to the electric main will be documented to be temporary.

But in fact, this connection can be used for an unlimited amount of time (with timely payment of the tariff for the used electricity, of course).

To conduct light in a change house, you will need the following:

• two ordinary sockets;
• switch;
• a ceiling lamp and several small lamps;
• short circuit fuse;
• conductors themselves.

Experts initially advise drawing up a detailed plan for the location of electrical wiring in a change house. So it will be much easier to make an estimate and purchase all the necessary components.

Naturally, this procedure is carried out in exactly the same sequence as for an ordinary private house.

The cross section of the conductors must be selected on the basis of electrical appliances that will be used in the change house on an ongoing basis. The cross section must be selected based on their total power.

For this, there are specialized tables, they indicate the cross-sections, both for aluminum conductors and for copper ones.

Professional electricians also say that the supply of electricity can be carried out not only by air, but also with the help of a trench. Taking into account that the change house stands on personal plot, which is the property of the host, this method is preferred.

Access to electrical wiring is always available (if it is laid in plastic cases). That is, it can be modified at any time in the future.

The video will show the process of rearranging the change house, which was filmed in one frame:

For a comfortable stay in a country or construction trailer, it is necessary to connect the change house to the mains. Electricity is required for space heating, the use of household appliances, room lighting and other needs. Of course, there are some nuances that must be taken into account in order to avoid violations of safety standards. Consider how to conduct electricity in a change house and what considerations should be followed in this case.

Coordination. Before you directly connect the trailer to the power grid, you need to obtain permission from the organization responsible for the supply of energy in the area. Power supply coordination country change house usually carried out in a local dacha partnership. In this case, you must specify the type of electrical network (single-phase or three-phase), the declared required power and other supply parameters. The change house does not apply to capital construction projects, therefore the connection in this case is considered temporary, although this status does not impose any restrictions on the use of energy.

Equipment. Connecting electricity to a change house is no more difficult than to a private house or a full-fledged cottage. You will need cables for this. lines of force, sockets, switches, lamps or electric lamps, junction boxes, cable channels or corrugation, as well as short circuit fuses, a meter and a circuit breaker. Wires to the change house are usually pulled through the air from the nearest support pole and are introduced into the room through an insulated hole in the wall. The more costly option is underground laying cable to the trailer using insulating plastic or asbestos-cement pipe. The connection process uses standard set electrical tools.

Conducting wiring. Initially, a scheme is created for connecting the change house to electricity, in which the direction of laying power lines and installing sockets, switch boxes, switches, lamps and other electricians is noted. After that, the appropriate marking of the location of cables and equipment is carried out on the walls. Wiring can be done in a closed way, that is, before warming the change house, or open over the finish. Next, direct work on the installation of electrical equipment begins:

What is important to remember when connecting a change house to electricity

In the question of how to conduct electricity in a change house, there are "pitfalls" that must be taken into account when carrying out work. First of all, you should coordinate with the supervisory authorities the very fact of connecting to the power network, as well as establish energy consumption rates, tariffs, etc. - otherwise, violations are possible on your part, which is fraught with certain sanctions, up to fines or cutting off the electricity supply . In addition, you need to consider for what purposes you need a change house:

• construction trailers are subject to increased fire safety requirements, for example, only metal corrugated hoses are used to insulate wiring;
• if the change house is used as a workshop and is equipped with powerful equipment, then it is recommended to connect a three-phase 380-volt voltage to it; for a residential trailer, a single-phase 220-volt voltage is sufficient.

When purchasing cables, switches and other electrics, carefully look at its specification - it must correspond to the connected equipment in terms of withstand power, resistance and other parameters.
