Wire marking color
The color insulation of conductors today is an indispensable attribute for successful and correct installation of electrical wiring. Such a decision is already in no way able to make darts beautiful and suitable for a gentleman, tse - better color marking, standardized and regulated in the entire civilized world, like, without overkill, necessary.
The color marking of the wires is given more accurately by the skin conductor, the color of the insulation lived in recognition of a group of wires, and it made the process of switching and installation easier. Such a solution includes pardons, it is possible during installation, which can lead to a fatally unsafe injury with an electric jet or a short flicker. Repair and maintenance of the electric power supply is also becoming safe, as it can be more accurately marked.
The standard of the PUE shows the colors of the marking, and this standard is able to easily identify a leather conductor, a leather core of a cable in a group for a color or for an alphanumeric code.
As a rule, the conductor has a full color scheme, but it is permissible and the marking is less than the last few lived, at the switching points, where it is possible to stop the color of the electrical tape or the color of the cambric. Let us take a closer look at the report, as it is the same way marking for single-phase, three-phase struma and fast strumu.
Standard color marking of busbars and wires for three-phase fencing snake struma:
At the rails of a three-phase coiled stream, high-voltage transformers are introduced, both at stations and at substations, as well as tires, frayed at the foot of the color, depending on the phases:
Phase "A" - prepared in a yellow color;
Phase "B" - garnished in green colors;
Phase "C" - crafted in a red color.
Standard color marking for wires and tires for a permanent strum:
For lancers of the post-strumu, there are only two tires: positive and negative. Here, the positive wire (positive charge bus) is marked with a red color, and the negative wire (negative charge bus) is marked with a blue color, even zero and phase wires are fundamentally different here. The middle drіt (M) is marked with a black color.
At the vipadku, if the line of the fast strumu, which is to avenge two conductors, is created for the help of the guard of the tripwire lancet of the fast strumu, the conductors are marked so by themselves, like the guides of the tripartite lancet.
Phase, zero and earth in electrical wiring:
The electric wires of the changeable struma are laid with a rich wire in the insulation of the wires of a different color, which greatly facilitates the installation process. As a matter of fact, only one installer is working, and in the future maintenance, that repair of the fence will be carried out by other people;
Ale, for the old hours, it was a fair problem, because the insulation was victorious in one direction - either it was white, or it was black. Now the standard has been modified, and it complies with GOST R 50462 "Identification of conductors for colors or digital designations", lived around in cables, strictly regulated designations.
The function of marking is to create the possibility of a quick and easy scientific recognition of a specific skin conductor for any kind of yoga dilyantsi, which is one of the main powers of PUE.

Zero working explorer (N) can be blue marked. For zero zakhisny explorer (PE) - yellow-green markings at the sight of swarms of uzdovzh or lived across. Such marking in the name combination of colors is only relevant for grounding conductors (for zero-voltage conductors).
If the zero-working conductor of the vikonanie is confused, then for all the days of the marking, it will be robbed in blue color, and in the places of arrival (at the conductor’s ends) - yellow-green smuga, or else: yellow-green conductor in blue colors.
So, zero darts are marked with such colors:
Zero working wire (N) - marking in blue color;
Zero pass (PE) - marking with a yellow-green color;
Zero Confusion (PEN) - marked with yellow-green colors from blue marks on the ends or navpak (div. vishche).
The phases of the darts, conforming to the PUE standard, can be marked with one of these colors: red, black, violet, brown, gray, erysipelas, orange, turquoise, or white.
If a single-phase electric lance is cut off by a path leading to a three-phase railing, then the phase wire of a stripped single-phase railing is guilty of being bound by a color with an output wire of a three-phase railing, as it is a wire.
The wires are marked so that the colors of the phase wires in the same order did not coincide with the color of the zero wire. And if a non-marking cable is installed, then the colors of the marks are scattered on the ends of the wires, at the junctions, for additional cambric from heat shrinkage or color tape. Ale for zapobіgannya zayvoї z vygotovlennya mitok, dosit spochatka correctly choose the color of insulation, making a cable sufficient for your needs.
Sometimes the electrician in the robot can be brought into contact with not even acceptable situations, if the wiring is already broken, and it is not connected to the shield, it is not marked, in which case people can be brought to watch for an hour and show the “phase”, “zero” and “grounding”.
However, keep in mind that it’s not possible to create a different color of a color, you can splendidly wink over a color, and then you need to remember the color of the color, even if you want a color heat shrink or a color. Always remember that when laying electrical wiring, it is necessary to protect and always take care of safety equipment.
