Please help improve this article by introducing citations to additional sources. Light blue is the color used to identify intrinsically safe conductors, and must not be used for any other type of conductor.
This way, work will be safer, and iec 60446 wiring colours maintenance will be easier. Personal tools Log in. International standard IEC Basic and safety principles for man-machine interface, marking and identification – Identification of equipment terminals, conductor terminations and conductors defines basic safety principles for identifying electrical conductors by colours or numerals, for example in electricity distribution wiring.
Printed text on iec 60446 wiring colours label, though, could identify which specific workstation uses that cable, which port on the server it should be connected to, as well as when the cable was installed.
From Wikipedia, the free encyclopedia. While confusion in identification of these conductors could be dangerous, the combinations of colours used usually resolves ambiguities. A mnemonic advantage of the new colours is that the first two letters of “BLue” and “BRown” match iec 60446 wiring colours corresponding positions on the BS socket face: List of International Electrotechnical Commission standards.
Wire markers should be visible during installation and normal maintenance of the wiring systems. Different codes are popular in different areas. Self-laminating wire wraps and heat-shrink tubes are available to create clean, professional labels for your project. Articles Wire Color Coding.
This extension is expected to be adopted across Europe and may even find its way into a future revision of IEC Iec 60446 wiring colours standards Electrical wiring. For a single AC phase: When those labels use colouurs text, they should use high-contrast and durable print. British Standard BS In some areas, a color code is specified by law; other areas rely on common practice. If a circuit includes a neutral or midpoint conductor, then it should be identified by a blue colour preferably light blue.

This article relies diring or entirely on wiing single source. Applying Color Codes to Wiring Most narrow wires will be color-coded by the manufacturer, using insulation of different colors. There are many wire identification standards, and many of them rely on color codes.
It has also been suggested iec 60446 wiring colours the new phase colours are difficult to distinguish in low-light conditions, but the same can be claimed for most colour combinations, including the old British phase colours.
Iec 60446 wiring colours is iec 60446 wiring colours in NEC article Archived from the original on 12 April For a transitional period April — March either set of colours were allowed but not bothprovided that any changes in the colour scheme are clearly labelled.
Relevant ic may be found on the talk page. Note that older installations may use different color codes. From Aprilonly the new colours should be used for any new wiring. With information wiring, printed labels can be a necessity.
Wire Color Coding
For colour cases, it becomes even more important to have a wirin wire labeling system. Not all wire color codes are the same, though, and some even contradict each other.
It depends on your location, installation type, voltage, and other factors. Which standard should be used in your facility? The installation of cables with the ‘new’ colours in an installation where the ‘old’ colours exist, could leave the way open for confusion; iec 60446 wiring colours is important in such situations that consideration is given to correct identification of the cables — with the use of marker tags if necessary. iec 60446 wiring colours
