Hong Kong Wiring Color Code
New Cable Colour Code From 1 July 2009, new colour coded cables have to be used in new fixed electrical installations in Hong Kong. In the old cable colour code, the colours of blue and black are used to identify phase and neutral conductors respectively. In Hong Kong, the color coding for electrical wires varies depending on regional standards.
The Electrical Wiring Colour Code of Hong Kong specifies that wires used to carry AC system voltages between 500V and 1000V must be color coded yellow/green, blue, grey, white, brown, black, purple, orange, or red. Additionally, using the correct wire color code will help ensure the safety of everyone working on the project. Wires are important components in many electrical systems, so understanding the color code is critical.

When it comes to wiring projects in Hong Kong, the right wire color code is essential for safety and functionality. As of 1 July 2009, Hong Kong mandates the use of a new wiring colour code in all new fixed electrical installations. The updated scheme replaces the old colour code with significant changes in identifying phase and neutral conductors.
The International Electrotechnical Commission (IEC) has set forth a standard color code for electrical wiring, which is used in Hong Kong. The IEC color-coding system is based on five main colors - brown, blue, black, gray, and green. These colors are then assigned various meanings to help electricians correctly identify and connect wires.

Wire color code HK is based on a system of seven standard colors used to identify wires in a wiring diagram. The colors are black, white, red, blue, yellow, green, and brown. The new edition of the Code of Practice for the Electricity (Wiring) Regulations has been published.
This new edition will be fully implemented on 31 December 2021 to replace the 2015 edition, after a grace period of one year. During this grace period, compliance with 2015 edition of this Code of Practice should be regarded as compliance with the relevant aspects of the Electricity (Wiring.
