Single core cable is commonly used where individual conductors are required for electrical installations, distribution boards, control panels and equipment wiring.
Our range includes colour-coded conductors for easy circuit identification, including brown, blue, black, red and green/yellow earth cable, available in various conductor sizes and purchase lengths.
Essential Cable for Fixed Electrical Wiring
Single core cable is designed for fixed electrical installations where individual conductors are required. Unlike flexible multicore cable, each conductor is supplied separately, allowing installers to select the required colours and route circuits individually through conduit, trunking, control panels and electrical enclosures.
Single core cable is widely used for power distribution, lighting circuits, switchgear, consumer units and commercial electrical installations. Its durable PVC insulation provides reliable protection while allowing each conductor to be easily identified by colour.
Understanding Single Core Cable Designations
Many single core cables are identified using harmonised European cable designations together with traditional UK reference numbers.
For example, 6491X / H07V-R is one of the most commonly used single core cables for fixed wiring installations.
- H = Harmonised cable standard.
- 07 = Rated voltage of 450/750V.
- V = PVC insulation.
- R = Stranded rigid copper conductor.
The UK reference 6491X is widely recognised throughout the electrical industry and refers to a PVC insulated single core cable manufactured to British and harmonised European standards.
Typical Applications
Single core cable is commonly used in:
- Consumer units and distribution boards
- Power and lighting circuits
- Electrical control panels
- Industrial control equipment
- Commercial electrical installations
- Conduit and trunking systems
- Earth bonding and protective conductors
Colour Identification
Single core cable is available in a range of insulation colours to assist with circuit identification and compliance with modern wiring practices.
Our range includes commonly used colours such as brown, blue, black, red and green/yellow earth, making it easy to identify live, neutral, switched live and protective conductors within electrical installations.
Choosing the Right Single Core Cable
When selecting single core cable, consider the conductor size, installation method and intended application. Larger conductor sizes are suitable for higher current carrying capacities, while smaller sizes are commonly used for lighting circuits, control wiring and auxiliary equipment.
Our single core cable is supplied in convenient 100m rolls, making it ideal for professional electricians, contractors, sign makers and commercial lighting installers.
