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.
