We’ll look at the BT wiring colour code old and new, to help you make sure your wiring is up to code.

BT Wiring Colours Old and New



The BT wiring colour code consists of five different colours, each representing a specific type of wiring. The colours are green, orange, blue, brown and grey.

Green Wires



Green wires were traditionally used for line 1 wiring. This wiring was mainly used for telephone line installations prior to the 1990s. This wiring should not be used with modern equipment as the insulation is not capable of handling the newer, higher voltages.

Orange Wires



Orange wires were introduced in the 1990s and were mainly used for line 2 wiring. This wiring is still used today, and can be found in many homes and businesses as an alternative means of connecting telephones, computers and other communication devices.

Blue Wires



Blue wires are used for line 3 cables, which are mainly used for broadband, television and radio. This type of cable was introduced in the 2000s and is mainly used for digital and satellite services.

Brown Wires



Brown wires are used for line 4 or 5 wiring. These are primarily used for power cables, as they are able to handle higher voltage than other types of cable. Brown wires are typically also used in high-voltage installations such as power plants and transmission lines.

Grey Wires



Grey wires are used for line 6 wiring, which is mainly used for control wiring. This type of wiring is primarily used in industrial settings and is not suitable for home use.

Conclusion



Understanding the BT wiring colour code is essential for both old and new wiring installations. It will help you and your electrician to determine what type of wiring must be used and how it should be connected. This guide has provided an overview of the different colours and what they represent, giving you a better understanding of the BT wiring colour code.
