Color of rods phase, zero, earth

In order to facilitate the installation of electrical wiring, all cable and conductor products can be marked in different colors. As a rule, in houses or apartments, lighting fixtures, connecting sockets are connected to three additional wires. The skin of them may be well recognized by the household electric fence. To that understanding of the color of the wires of the earth may be of great importance. For this day, the hour for installation and further repair is reduced. Zavdyaki color marking, be it some kind of connection, do not become especially folded.

Ground wire

For the purpose of identifying the grounding dart of the native vicarious, yellow-green colors are used. Sometimes it is possible to use conductors from the insulation only of the yellow color. More often, light-green colors are victorious. Sound like this, the darts are marked with the symbols PE. However, as a grounding sound of confusion from the neutral, vin is designated as PEN. Vin farbuєtsya in a green-yellow color, and on the ends there is a blue braid.

At a separate shield, a ground wire is connected to a special busbar, or to the body of that metal door. At a separate box, the wires are wired with similar wires, transferred from lamps and sockets, with special grounding contacts. The grounding wire does not need to be connected to the outhouse of the outhouse connection (PZV), so the outbuildings are wired there, where only two darts are needed for electrical wiring.

Zero conductor (neutral)

For the zero conductor, it is traditionally neutral to win the blue color. The connection in the sub-panel shield is connected through a special zero bus, which is indicated by the symbol N. All the rods are connected to the bus, which has a blue color.

The bus itself is driven from the introduction through. In some situations, the installation can be carried out without any intermediary without any additional automatic attachments.

At the rozpodіlnіy box, all the neutral darts of the blue color are joined at once and do not take part in the commutation. Vignatok to become provіd, scho ide vіd vimikacha. Connecting the blue wires to the sockets is connected to the additional special zero contact, which is indicated by the letter N. This marking is put on the back of the skin socket.

Color of the phase drotu

The phase cannot be precisely defined. Black, brown, red and other colors are often sewn up, which look like green, yellow and blue. At a separate shield installed near the apartment, there is a phase dart, which goes out of the way, is connected to the contact of the automatic vimikach, we will open it from below. On other schemes, the conductor can be connected from the outbuilding of the switch.

In vimicachs, the phase takes the fate of the commutation. With this help, the fading and opening of the contact - turning on and wiping out. In this way, the supply of voltage is adjusted to slow down, and at the time of consumption, the supply is applied. At the sockets, the phase conductor is connected to the contact with marking L.

Appointment of darts

Sometimes they blame the situation, if it is necessary to assign recognition to these other darts for the presence of the new marking. Naybіsh we will forgive that in the widest way є. With help, you can accurately set which wire will be phase, and which one will be null. We need to turn on the power supply to the shield. On the fol- lowing of this county, two conductors are cleared and slaughtered, they filed one for one. Then it is necessary to turn on the power supply and use it as an indicator of the recognition of skin disease. Like a light bulb burned out on contact with the residential - whole phase. So, insha lived bude neutral.

For the obviousness of the electrical wiring of the grounding rod, it is recommended to use a multimeter. Tsei prilad possession of two tentacles. On the back, the vimiryuvannya strumum is installed in the range of more than 220 volts at the indicated value. One tentacle is fixed at the end of the phase wire, and the other is assigned ground zero. At the time of zero, the display will show a voltage of 220 volts. When turning the grounding rod, the voltage will be noticeably lower.

Markuvannya

It is not only the color of the wires phase, zero, earth, but also see the marking, the letter and the digital sign are in front of it. The first letter A indicates the material of the dart - aluminium. For the presence of these letters, the material will be angry.

The main marking of wires in electricity:

• AA - for a multi-core aluminum cable with additional braids from the same material.
• AC - dodatkove lead braiding.
• B - the presence of zahistu in vіd vologi i dodatkovoї plaiting from two-ball steel.
• Bn - non-combustible braided cable.
• D - the presence of the sour shell.
• P - husk with gumi.
• NR - gum shell from non-combustible material.
