The wiring in the garage is also necessary, as in any other domestic or utility room. Without light, it is not necessary to do without the evening, but electricity is also necessary for the work of various equipment: a battery charger, a wrench, pump for tire paging, automotive, electric drills, etc. About how to pave wiring in the garage will be told in this article.

How starts installation: types of garage electrical wiring

Installation of electrical wiring in the garage begins immediately after the end of the construction of walls, overlapping and setting the gate. At the first stage, the electrical wiring in the garage is impossible: putting the power cable after all necessary coordination work with electricity suppliers and the leadership of the garage cooperative carries out an electrician. His task is the installation of outdoor wiring.
The outer wiring is performed by cable for external work from insulators on supports (on a pipe-resistant) or from a junction box, which is part of a centralized line. It can be either an air line, or underground cable entry: it all depends on the technical conditions.
For air input (it is used most often) It is important that the cable is at the height (minimum):

• 6 m from the ground when installing over the roadway;
• 3.75 m during installation over the pedestrian zone;
• 2.75 m from the ground near the garage.

It is used for this insulated flexible cable with copper (at least 6 mm² in cross section) by veins or aluminum (at least 16 mm²). It is introduced under the roof in such a way that the rainwater falling inside the room was impossible. In addition, the protection of the corrugated metal pipe is performed. After that, the sealing of the revincible mastic is produced.
If the cable is laid underground at a depth of less than 2 m, it should be additionally protected by reinforced concrete plates or steel box. The cable must be the appropriate type, protected from rodents with a special impregnation, and from mechanical damage - armor. To enter it in the foundation of the structure there should be a hole, and a pipe is installed to protect the input.
Connecting an individual power cable is possible only after removing the voltage, which has the right to fulfill only a qualified specialist. The installation of the outer wiring is edged with the installation of a two-pole circuit breaker directly in the garage. As a rule, such machines are placed near the entrance door, in the distribution panel.
After that, the installation of the internal wiring begins. Such wiring in the garage with your own hands - performing work for the one who owns the foundations of electrical engineering. There are certain rules that need to be performed, so further - information on how to make wiring in the garage.

Start internal electrical work

Before the installation begins, the wiring diagram is compiled in the garage. Next - on points.
1. First, consider where sockets are needed, taking into account the height of the racks, the location of the shelves. The electrical wiring diagram in the garage can be applied directly onto the wall: the corresponding characters are designated junction boxes, switches, sockets, installation locations on the ceiling and walls. The switch should not overlap the front door.
2. It should be borne in mind that only a reduced voltage can be used to illuminate the cellar and observation pit - 36 V, since the garage has increased humidity and the presence of fuel evaporation. It is necessary to provide a decrease in the lowering transformer.
3. Junction boxes are placed in such a way as to divide the internal network into separate groups in order to reduce the cable consumption and uniform load distribution. As a rule, the lighting group and the socket group are mounted independently of each other.
4. Cables are packed, usually, at a distance of 100-150 mm from the ceiling. The rosette group is mounted using a cable with three veins, of which one - for grounding: it is necessary for safety.

5. Automatic opening systems and alarm systems (if available) are switched from the power grid and are equipped with an uninterruptible power supply unit.
6. The grounding circuit of four two-dimensional corners must be mounted before the fill of the foundation until the soil is open. If the area for the grounding contour is not enough - the pin ground is mounted. The tire for connecting grounding cables is removed into electrical boards.

Hidden installation of electrical wiring

Wiring wiring in a garage built from foam concrete blocks or bricks can be performed in a hidden way:

• the cable laying lines are performed
• wiring stacked in them
• then "fit" with the help of alabaster alabaster in several places.

There is another way:

• With the help of a diamond circle installed on the grinder, narrow and deep grooves cut through.
• The flat cable of GDP-1 × 2 or GDP-1 × 3 (cross-section of copper veins - 1.5 mm² for lighting and 2.5 mm² - for the outlet group) is stacked. This gives certain advantages: it is not necessary to "harden" the cable (it is securely kept in a narrow stroke), the work is performed faster and easier.
• If you want to pave two cables in one direction, you have to make a wide stroke or two parallel slots.
• The cable is only horizontally or vertically: it is necessary in order not to damage the wiring when the shelves hangs.
• Built-in sockets and switches are installed in plastic submersions, the holes for which are prepared using a crown - special nozzle for the perforator.

• When all the wiring is made, the cable strides are sealed with a plaster solution, after which it is possible to fit the walls of the walls with ceramic tiles or plastering.

Outdoor Mounting Method

The wiring in the garage (photo for clarity is presented) does not have to be hidden: the interior of the "car for auto" does not make high demands, and for metal garages, the outer wiring is the only possible solution.
The easiest way to perform a layout with the help of plastic boxes. Their sizes are selected in accordance with the thickness and number of cables. Fasten boxes that make predominantly decorative functions, to brick (concrete) walls and ceiling with a dowel, and after the installation is completed, covered with lids on the latches.

For garages from sheet iron, a plastic or metal corrugated tube is suitable. It is fixed by clamps to the walls, for which the already existing fasteners connect the sheets. If it is necessary to drill holes in the metal for mounting the clamps - under the helms of the screws from the outdoor side insert sealing gaskets made of soft metal (copper, aluminum): rubber or plastic collapse over time, and rain water will fall into the resulting gaps.
For external wiring, outlets, switches and junction boxes are required.

Installation of electric flap

1. Each pre-signed internal wiring cable is introduced into an electric shield. For the device, the latter requires a metal mounted or an embedded locker (depending on the type of wiring), with the door.
2. An electric meter is installed and a group of automata that is fixed on a DIN rail.
3. The cable that is connected to the meter is connected to the meter.
4. Each cable is connected by the phase wire to the terminal terminal of the appropriate estimated load of the machine.
5. Input terminals are connected by a common wire and connected to the output terminal of the electric meter.
6. Zero and ground wires are connected on individual pads.

It will not be superfluous to install the protective disconnection device and the voltage relay: in case of a critical change of its amplitude, this relay will instantly turn off the internal network, thereby saving the devices from damage.
Electrockers are assembled with a disconnected input two-pole machine. At the end, the trial inclusion and verification of the performance of all network elements is performed.
