Usually easy to identify the phases of a power system, they are marked with different colors. It has many advantages. For example, if you divide the load between phases is distinct color phases, phase identification will be difficult to split time. Also find out how to connect to a single phase induction motor is possible without the need for testing. Most standard IEC 60446 standard is there to do it. Unfortunately, this standard is not taken seriously and practice systems different colors may be used in non-professional jobs. (Not to mention the use of different colors in the final price increases, mostly colored wires sometimes beat, especially on the boards of companies making invalid, it (the color of the panel) is very common) Advanced Audio Coding standard used the color scheme to prevent errors and ensure the functioning of the system, the following is recommended: the color coated cables (cables) on the internal wire multi-wire cables (cores) or the Shynhhay copper busbar (busbars) electric Sayrvsayl same Ayqbndyha you know, the IEC standards are widely available and should be purchased anywhere you want and it is very difficult. However, some parts of this standard has been published in various books and websites can be found on its provisions. Tshkhsys ground wire (usually yellow in color with green tape is pulled) do not. The combination of the colors green and yellow colors are permitted but should not be used in any of the ingredients except for the protective system. Use neutral colors or neutral conductor if the circuit includes a neutral point or null, then the conductor must be marked with a blue color (preferably blue). And blue light should not be used for any other conductors. Protective conductor system (ground) color combinations yellow / green and is widely used to identify the protective conductor. Hadya PEN PEN conductor conductor which includes two conductor PE (protective earth) [Protective Earth] and N (neutral) is. Usually the conductor in the distance between the posts to be used in residential homes where PE and N conductors are separated. In the UK it's called Protective multiple earthing) PME) is also known, which cause frequent connection neutral conductor / earth is the real ground reduces risk neutral firm. The Australian system called multiple earthed neutral) MEN) is known. Ayqdar PEN conductors, or have a yellow / green lined with blue signs at both ends to be determined, or should Rvshnmshkhs over them with water, and at the end of Markhayzrd / green used. America, Canada and Japan in the three countries in IEC allow the use of other colors is given in the following character. Gray or white neutral wire (instead of light blue) green protective conductor (yellow-green instead) UK British Standard BS 7671, according to the IEC 60446 standard was abandoned in 2001. In addition to the color numbers if conductors are identified by number, this number should be written by Arabic digits. The numbers 6 and 9 should not be confused with the line is drawn. In addition, the yellow-green conductors will not be numbered.

The Chinese standard colors (yellow, green, red) are also common.
