Which standard should be used in your facility? 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.
The color codes used for wires can vary. This standard provides a consistent approach that can be applied to many different kinds of connections over time. For higher-voltage cases, it becomes even more important to have a documented wire labeling system. 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 iec 60446 wiring colours situations that consideration is given to correct identification of the cables — with the use of marker tags if necessary.
Most narrow wires will be color-coded by the manufacturer, using insulation of different iec 60446 wiring colours. The three countries United States, Canada and Japan are mentioned in a note in the standard for iec 60446 wiring colours different colours:.
This article relies largely or entirely on a single source. Not all wire color codes are the same, though, and some even contradict each other.

A mnemonic advantage of the new colours is that the first two letters of “BLue” and “BRown” match colourrs corresponding positions iec 60446 wiring colours the BS socket face: Iec 60446 wiring colours way, work will be safer, and future maintenance will be easier. The standard wiring colours in the UK are as of the same as elsewhere in Europe and Australia and follow international standard IEC Archived from colurs original on 12 April Different codes are popular in different areas.
This colour scheme had already been introduced for appliance flexes in the UK in the early s, however the IEE recommended for fixed wiring until a different scheme.
While color can rapidly provide some information, the amount of information is limited. The color code for AC power wiring is similar to the code used in the United States: Wiring used for telecommunications or computer network applications use a different approach for identifying data cables.
When wires are larger than 6 AWG, they will typically be iec 60446 wiring colours with black insulation. While confusion in identification of these conductors could be dangerous, the combinations of colours used usually resolves ambiguities. International standard IEC Basic and safety principles for man-machine interface, marking and identification – Identification of equipment terminals, conductor terminations and conductors defines basic iec 60446 wiring colours principles for identifying electrical conductors by colours or numerals, for example in electricity distribution wiring.
IEC standards Electrical wiring. This extension is expected to be adopted across Europe and may even find its way into a future revision of IEC This page was last edited on 10 Novemberat When those labels use printed text, they should use high-contrast and durable print.
Wiring colour codes
Please help improve this article by introducing citations to additional sources. If a circuit includes a neutral or midpoint conductor, then it should iec 60446 wiring colours identified by a blue colour preferably light blue.
The standard has been withdrawn; the fourth edition IEC Self-laminating wire wraps and heat-shrink tubes are available to create clean, professional labels for your project.
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 iec 60446 wiring colours current.
Wire Color Coding
Articles Wire Color Coding. In these cases, color colouts should be added during installation, using colored bands that wrap around the wire. Where more detailed information is helpful or even necessarythe DuraLabel line of label printers offer a simple and reliable way to iec 60446 wiring colours long-lasting markers and wire tags.
From Aprilonly the new colours should be used for any new wiring. However, these high-leg delta systems are uncommon with newer installations. Personal tools Log in.
