With information wiring, printed labels can be a necessity. IEC standards Electrical wiring.

Applying Color Codes iec 60446 wiring colours Wiring Most narrow wires will be color-coded by the manufacturer, using insulation of different colors. Retrieved from ” https: Self-laminating wire wraps and heat-shrink tubes are available to create clean, professional labels for your project. In some areas, a color code is specified by law; other areas rely on common practice. This page was last edited on 10 Novemberat Light blue is the color used to identify intrinsically safe conductors, and must not be used for any other type of conductor.

The color code for AC power wiring is similar to the code used in the United States: This way, work will be safer, and future maintenance will be easier. This extension is expected to be adopted across Europe and may even find its way into a future revision of IEC List of International Electrotechnical Iec 60446 wiring colours standards. Iec 60446 wiring colours standard has been withdrawn; the fourth edition IEC Personal tools Log in.

IEC – Wikipedia

If a circuit includes a neutral or midpoint conductor, then it should be identified by a blue colour preferably light blue. Archived from the original on 12 April Views Read Edit View history.


The standard colours in fixed wiring were iec 60446 wiring colours in with the regulations in other European countries and the international IEC standard. Which standard should be used in your facility?

Wire Color Coding

The standard colkurs colours in the UK are as of the same as elsewhere in Europe and Australia and follow international standard IEC While color iec 60446 wiring colours rapidly provide some information, the amount of information is limited. A mnemonic advantage of the 60446 colours is that the first two letters of “BLue” and “BRown” match the corresponding positions on the BS socket face: Where more detailed information is helpful or even necessarythe DuraLabel iec 60446 wiring colours of label printers offer a simple and reliable way to print long-lasting markers and wire tags.

Different codes are popular in different areas. There are many wire identification standards, and many of them rely on color codes. Relevant discussion may be found on the talk page.

Most narrow wires will be color-coded by the manufacturer, using insulation of different 6044. It depends on your location, installation type, voltage, and other factors. Wiring used for telecommunications or computer network applications use a different approach for identifying data cables. While confusion in identification of these conductors could be dangerous, the combinations colouts colours used usually resolves ambiguities. Please help improve this article by introducing citations to additional sources.

The color code for AC power wiring is similar to the code used in the United States:. Whatever marking system is used for the cables and wires in your facility, the markings should be durable enough to last as long as the wires themselves.

Wiring colour codes

From April uec, only the iec 60446 wiring colours colours should be used for any new wiring. Note that older installations may use different color codes. Wire markers should be visible during installation and normal maintenance of the wiring systems. Solar power systems and many battery systems use DC direct current power, rather than AC alternating current.


When wires are larger than 6 Iec 60446 wiring colours, they will typically be manufactured with black insulation. 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.

This article relies largely or entirely on a single source. The installation of cables with the ‘new’ colours in an installation where the ‘old’ colours exist, could leave the way open for confusion; it is important in iecc situations that consideration is given to correct identification of the cables — with the use of marker tags if necessary.

From Wikipedia, the free encyclopedia. The color codes used for wires can vary.

Articles Wire Color Coding. This is required in NEC article This colour scheme had already been introduced for appliance flexes in the UK in the early s, iec 60446 wiring colours the IEE recommended for fixed wiring until a different scheme.

For a single AC phase: It has iec 60446 wiring colours been suggested that 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. However, these high-leg delta systems are uncommon with newer installations. Colours picked from IEE Harmonised colours document and converted using coblis.
