The color code for AC power wiring is similar to the code used in the United States:. List of International Electrotechnical Commission standards.

When those labels use printed text, they should use high-contrast and durable print. This page co,ours last edited on 10 Novemberat The color codes used for wires can vary. British Standard BS There are many wire identification standards, and many of them rely on color codes.

International iec 60446 wiring colours IEC Basic and safety principles for man-machine interface, marking and iec 60446 wiring colours – Identification of equipment terminals, conductor terminations folours conductors defines basic safety principles for identifying electrical conductors by colours or numerals, for example in electricity distribution wiring. The standard has been withdrawn; the fourth edition IEC Views Read Edit View history.

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 such situations that consideration is given to correct identification of the cables — with the use of marker tags if necessary. 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 used for telecommunications or computer network applications use a different approach for identifying data cables.


Solar power systems and many battery systems use DC direct current power, rather than AC iec 60446 wiring colours current.

The standard colours in fixed wiring were harmonized in with the regulations in other European countries and the international IEC standard. While confusion in identification of these conductors could be dangerous, the combinations of colours used usually resolves ambiguities.

It depends on your location, installation type, voltage, and other factors. The colour change has been controversial and was delayed for three decades, because the colour blue which was previously used as a phase colour is now the colour for neutral, and the colour black which was previously used for neutral now indicates a phase. If a circuit includes a neutral or midpoint conductor, then it should be identified by a blue colour preferably light blue. With information wiring, iec 60446 wiring colours labels can be a necessity.

The standard wiring colours in the UK are as of the same as elsewhere in Europe and Australia and follow international standard IEC For a single AC phase: When wires are larger than 6 AWG, they iec 60446 wiring colours typically be manufactured with black insulation. Iec 60446 wiring colours has also 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.
