The International Electrotechnical Commission (IEC) standard 60446 provides guidelines for basic and safety principles for electrical wiring systems. It defines specific colours for different types of conductors and ensures global consistency in electrical installations.

NEC

In the United States, the National Electrical Code (NEC) prescribes specific colours for different conductors. Although the NEC colour codes differ slightly from the international standards, they are widely followed within the United States.

BS 7671

The British Standard BS 7671, also known as the IET Wiring Regulations, outlines the requirements for electrical installations in the United Kingdom. It includes the colour codes specified by IEC 60446 and is widely adopted in many other countries as well.

5. Colour Codes for Single-Phase Wiring

In single-phase electrical installations, different colours are used to identify the neutral conductor, protective earth conductor, and line conductors (phase). The following colour codes are commonly used:

Neutral Conductor

The neutral conductor, which carries the current back to the source, is typically identified with the colour blue.

Protective Earth Conductor

The protective earth conductor, responsible for grounding and providing safety, is usually denoted by the colour green or green with yellow stripes.

Line Conductors (Phase)

The line conductors, carrying the current from the source to the load, are identified by different colours depending on the region. For example:

• In many countries, including the United States, line conductors are typically black, red, or any colour other than blue or green.
• In the United Kingdom and other countries following the IEC 60446 standard, line conductors are commonly brown, black, and grey.
• It is important to consult the specific regulations and standards applicable in your region for accurate information on colour codes.

6. Colour Codes for Three-Phase Wiring

In three-phase electrical systems, additional conductors are present to facilitate the distribution of power. The colour codes for three-phase wiring are similar to those used in single-phase wiring, with some variations. The colour codes include:

Neutral Conductor

The neutral conductor in three-phase wiring is usually marked with the same blue colour used in single-phase systems.

Protective Earth Conductor

The protective earth conductor retains its green or green with yellow stripes designation in three-phase systems.

Line Conductors (Phase)

In three-phase systems, line conductors are typically identified using different colours than those used in single-phase systems. The specific colours vary depending on the region and standards in use.

7. Additional Colour Codes

Apart from the standard colour codes for single-phase and three-phase wiring, there are additional colour codes for specific applications:

Control Wiring

Control wiring, used for operating electrical devices and equipment, often follows its own set of colour codes. For example, control wiring may use colours such as yellow, orange, and violet to distinguish different control signals.

Communication Wiring

Wiring for communication systems, such as Ethernet or telephone lines, may have its own unique colour codes to differentiate between different cables or functions. Commonly used colours include white, blue, orange, and green.

Low Voltage Wiring

In low voltage systems, where safety voltage levels are used, different colour codes may be employed. These colours are designed to prevent confusion and ensure the correct connections. Examples of low voltage colour codes include purple and white.

Extra-Low Voltage Wiring

Extra-low voltage systems, such as those used in doorbells or certain sensors, also have specific colour codes. These codes help distinguish between different types of connections and ensure proper installation and operation.

8. Exceptions and Variations

While international standards provide a common framework for electrical wiring colour codes, it is important to note that some countries or regions may have specific exceptions or variations. Local regulations or specific applications may necessitate deviations from the standard codes. Therefore, it is crucial to consult the relevant guidelines and codes applicable to your area before undertaking any electrical installation or modification.

9. Safety Considerations

Ensuring safety in electrical installations goes beyond following colour codes. Here are some important safety considerations:
