Wiring Colours UK Old is a time-honored tradition that has kept electrical devices running reliably for generations. It is an incredibly important component of any electrical installation and must be considered carefully when setting up any new wiring. Wiring simply put, is the act of connecting electrical components together in order to create a system. This is done with cables and wires which are usually coloured so that they can be easily identified. The most commonly used color coding system in the UK is known as “Old Colours”, which was used up until the mid-1980s.

The Old Colours wiring system uses seven common colours to distinguish between different types of cable or wire. These include black, brown, blue, green-yellow, red, yellow, and white. Each colour signifies a different purpose, such as live, neutral, earth, and power. In a typical household setup, live wire will always be black, while neutral wire will always be brown. Blue wires are usually used to indicate an earth connection, while red wires are generally used for power.

The Old Colours system is still widely used in British homes today, although it’s always important to check with an expert before beginning any electrical work to ensure safety and accuracy. If you’re unsure about a particular colour coding system, it’s always best to contact a qualified electrician who can help you get the job done correctly. With the right knowledge and a bit of hard work, you can make sure your wiring system is safe, reliable, and efficient.
