5 color logo

5.1 General The following color allows for identifying the conductors. Black, brown, red, orange, yellow, green, blue, purple, gray, white, pink, turquoise. Note. The above list of color taken from GB/T 13534. Recommended insulating color or color logo identifying the entire length of the conductor as the color, the color marker at the bare conductor and the connection end point except. Color flag is not required for identification or. --- concentric conductor cable; --- and the metal sheath of the cable conductor as a protective cover; --- not use a permanent marker of a bare conductor; --- may be used as the external protective conductor conductive portion; --- exposed conductive member used as a protective conductor. When the color coding is still confusing, allow additional signs, such as alphanumeric. 5.2 Use monochrome 5.2.1 Possible colors 5.3.2 - 5.3.6 Press, only where the protective conductor is less likely to occur confusion coloration, allows the use of a single green and yellow. 5.2.2 neutral or intermediate conductor Circuit comprises a neutral or intermediate conductor should be used as a blue color identification. To avoid confusion with other colors, it is recommended Use light blue. When possible confusion, light blue should not be used to identify any other conductor. In the absence of a neutral or intermediate conductor case, blue light can be used in identifying any other line conductors other protective conductor outside. If a neutral color identification for a bare conductor or the intermediate conductor, use 15mm 100mm wide stripes - pale blue in each Or the outer casing unit or may each reach areas marked or indicated from beginning to end with a light blue. Note 1. GB 3836.4 provides a terminal for identifying light blue intrinsically safe circuit, terminal box, plug and socket. Note 2. The United States, Canada, Japan, white or pale blue as a substitute of natural gray or neutral color in the central conductor identification. 5.2.3 AC phase conductors Priority black, brown or gray AC system phase conductor. Note 1. In the United States, Canada and Japan, marked in blue gray substituted for neutral or intermediate conductor. As may be mixed, not be used for identification gray phase conductor. Note 2. In the United States, Canada and Japan, for identifying a neutral gray or intermediate conductor, gray for no other purpose than the present standard. Note 3. The above color is not used to represent the color of the phase conductors rotational direction or phase adjustment. 5.3 Use of a combination of color 5.3.1 Possible colors Where it will not cause confusion, allowing the use of a combination of any two colors in the color list from 5.1 constituted. To avoid confusion, in addition to green - yellow color combinations outside, green and yellow should not be combined with other colors. 5.3.2 - green yellow composition is limited 5.3.6 application. 5.3.2 protective conductor Use protective conductor green - yellow color combinations identified. Note 1. To clearly identify specific conductors, may provide additional signs. Note 2. PEN, PEL and PEM conductors require additional color code. Green - yellow color is only recognized for identifying the protective conductor color combinations. Green - Yellow color composition should be done. per 15mm in length using a color-coded conductors, at least one color to cover the conductive surface 30% and not more than 70%, while covering the remaining surface of another color. If a bare conductor as a protective conductor, use green - yellow color in the entire length of the conductor, each sector or each cell or each easy touch And parts made color logo. If you use tape, only two-color tape. Note 3. For the protective conductor from its shape, structure or location easily recognizable, e.g. concentric conductor, you do not need the full length of the conductors has color patches, but Its end or contact portion is appropriate graphical symbols or green - yellow color or alphanumeric symbols clearly marked PE. Note 4. In the United States, Canada, Japan, use green alternative green - yellow color as color recognition protective conductor. Note 5. conductive portion may be used as the outer conductor PE, do not have color-coded. 5.3.3 PEN conductor PEN insulated conductors should use one method identifier. --- full-length green - yellow color, the other end with a light blue mark; or --- full-length light blue, the other end with a green - yellow color flag. Note 1. Select or method implemented by the relevant standards committee. Note 2. The following cases, additional blue logo on the terminal can be omitted. --- electrical equipment, if a particular product standard requirements have been included. --- wiring system similar to that used in the distribution industry, determined by the relevant standards committee. 5.3.4 PEL conductor PEL insulated conductor shall be marked in a full-length green - yellow color, a blue mark ends. Note. When the blue identifying one of the following two conditions are satisfied at both ends may be omitted. --- electrical equipment, if a particular product standard requirements have been included. --- wiring system similar to that used in the distribution industry, determined by the relevant standards committee. If PEL easily confused with PEN conductor or PEM conductor, alphanumeric marking according to 6.2.4 pointed at each end. 5.3.5 PEM conductor The insulated conductor shall PEM full length marked in green - yellow color, a blue mark ends. Note. When the blue identifying one of the following two conditions are satisfied at both ends may be omitted. --- electrical equipment, if a particular product standard requirements have been included. --- wiring system similar to that used in the distribution industry, determined by the relevant standards committee. If the PEM conductor or PEL easy to be confused with PEN conductor, alphanumeric marking according to 6.2.5 pointed at each end. 5.3.6 protective bonding conductors 5.3.1 shall be protected by bonding conductor green - yellow color identification.

6 alphanumeric identifier
