What color is the ground wire and what is the other marking

⁰

As a rule, the insulation is color-coded throughout the life of the conductor, in the few valleys only at the ends of the stream-conducting veins, or at the points of connection. It’s worth fighting for in order to make the swindle incapacitating when the conductors are connected, or only a few strum-conducting ones through dozens of meters of the attached laying. Krim sproshchennya elektromontazhny razraznennya elektroprovodka behind a color shortly an hour will look for problems in elektromerezhі and zamіni dіlyanok wiring, scho vyyshli out of tune or not vydpovіdat navantazhennu.

Zahalom parameters of electrical wiring are selected as tight as possible, and the recognition of electrical circuits, as may be:

triphasic;
single-phase;
postіynogo chi zminny strumu.

The electric wires of the changeable stream are created on the basis of a multi-wire (3, or less than 4 wires) electrical wiring of various insulation, although earlier conductors were used for this wire, as they were small for the entire motor. In Denmark, the marking of wiring for single-button electric lines and piece grounding has been brought up to a single standard, up to PUE-7, as well as GOST 12.2.007.00 and other standards.

The color of conductors of different types can be varied. In order to determine, as the decision was taken for a specific marking, the electrician is guilty of knowing that the lines are connected with one phase in the form of a three-phase line with us in front of the potency: for other conductors, it is necessary to consider the value of the company, or special terminals for connection. Likewise, there is a line of separation of the chains of the constant and the serpentine strum. The first signs are for living the electrical installation of high sweating, others - to provide electricity for lighting fixtures and other amenities at living booths, offices, as well as administrative and community life.

Vikonati installation without pardons will help to improve the convenience of congested wires on other electric lines. In addition, it is impossible to make a single order and/or spatial orientation of the connection of conductors, as well as the consistency of their parameters, which are visually assigned or for the literal designation of marking. For example, the zahisny conductor at the three-wire dart is to blame for the yellow-green mother or the dark-skinned insulation, and the connection of the yogo was traced to a special clamp on the connection point of the spozhivach. When installing the remaining levoruch (from the bottom), it is recommended to place the working zero dry from black insulation, and the phase - brown, orange thin. vіdtіnkіv - install the right hand (burn).

General principles of color marking

It is important to mark the electrical wiring behind the color of the amateur electrician in the area of \u200b\u200bsingle-phase electrical wires of a snake with a voltage of up to 1000 V with a dead-earthed neutral. However, those, in a certain color, the insulation of wiring in electrical circuits of technical recognition, it is difficult to remember and in the future do not confuse the wiring for home sockets and electrical cables for connecting an exhaustive power supply to the installations.

So, in three-phase chains of a zminny struma, the filling of tires and high-voltage wires is wound in the following order:

phase A - zhovtii;
phase B - green;
phase Z - chervoniy.

At the railings of the stationary stream, which are stagnant at the everyday life, at the electric substations, at the transport on the electric tyaz, there are two main tires ("+" and "-") and zero working with the sign "M". The first tire is worn by the red color, the other - by the blue one. Working zero tire "M" is to blame for the mother of black insulation.

Nareshti, in some valleys, it is necessary to mark the electrical wiring for the functional purpose of the electrical lines:

blackim - at the power chains;
chervonim - in the chains of the strum of the systems of cheruvannya chi signalization;
in blue - at the borders of the post-strum system of keruvannya and signalization;
yellow, green, or their combination - zero conductors from the protection function;
blakitnim - lived, not recognized for grounding, that connection with a zero robotic dart.

Colors for marking by butt wiring

What is the cost of electrical wiring, what is zastosovuetsya for the laying of butovyh electric lines, one thing, about what to say її zabarvlennya - mental recognition of the conductor. On the vіdmіnu vіd literal designation, scho to avenge the information about the material of the door and the information about the insulation.

Depending on the official standards, the colors of the dart can be said less about those that are recommended for the new to be accepted by the electrician:

blakytny - zero working average conductor of a tether of type n, zero in 1-phase tethers of a serpentine stream (designation N);
yellow-green - piece grounding, zahisny conductor or null-zahist (leteri PE);
a combination of yellow or green and blackite - confusion zero worker or zero grounding conductor (classically PEN);
black, brown, red, violet, syria, horny, white, orange, turquoise phase conductor (L).

When rozpodіlі funktsіy stremoprovіdnіh veins sіlіtаtаtі about those, which of them is zero, and like a phase, and also about those, that phase conductors are not guilty of spіvpadat for zabarvlennya with zero and grounding (PEN, PE or N). As a rule, there is a multi-wire wiring with one-bar markings, for the identification of conductors there is a color insulation or a special thermal tube.

It is important to remember a few moments about the null and zero of the explorer:

to get rid of the swindler for zero working wire (N) is guilty of such isolation of the black eye;
zero, as a guide, sound out the vein from yellow-green or dark-skinned insulation;
for a confused zero worker and a null conductor (PEN), it is standardly guilty to recognize the wires from the blue-coloured insulation and yellow smugs on the kintsy (or navpak).

To know the peculiarities of the color designation and the principles of the mental rozpodіl functions of the marking of the strum-conducting wires may be an electrician. Tse allow not only to speed up the process of laying the electrical wiring, but also to noticeably increase the quality of the vikonan robot, and also to simplify the process of servicing the electrical circuit at the future.
