National Single Core Cable 4mm - Blue

Key specs: copper conductor with a 4 mm cross-section, PVC insulation, blue outer sheath, flame retardant formulation, RoHS and CE compliant, UL rated, and rated for temperatures up to 90°C. Available in lengths of 3 m, 5 m, and 7 m for versatile installations.

Yes. The product is designed for both indoor and outdoor uses, with a robust blue polymer sheath that enhances durability in varied environments.

Choose based on your layout and distance between power source and load. For shorter runs, 3 m may be enough, while longer routes or installations with fewer terminations may benefit from 5 m or 7 m to minimize splices and reduce clutter.

Turn off power first. Cut to length, strip the insulation carefully at the ends, and connect to appropriate terminals, lugs, or connectors using correct torque. Avoid sharp bends and protect the cable with conduits or cable trays where needed. Use proper strain relief and ensure color-coded identification is maintained.

The cable is RoHS and CE compliant and UL rated, with flame-retardant properties for safer operation in domestic and industrial settings.

A single-core cable has one conductor per insulation layer, ideal for dedicated line feeds, simple circuits, or where a single live conductor is required. Multi-core cables contain multiple insulated conductors bundled together, used for more complex wiring where several circuits are run in parallel. Choose based on your circuit design and installation requirements.

Common use cases include domestic wiring for lighting circuits and outlets, small power feeds in workshops or offices, and general-purpose wiring where a robust, color-coded conductor is needed. It’s suitable for low- to high-voltage applications as per your project needs.

Avoid excessive bending radii, kinking, or crushing the insulation. Keep runs organized with cable managing accessories, ensure secure terminations, and protect cables from UV exposure or harsh chemicals. Use appropriate protective conduits in outdoor or exposed environments.

Yes. The 4 mm copper conductor is compatible with common electrical connectors, lugs, and terminal blocks designed for 4 mm conductors. Ensure connectors are rated for the current and voltage of your installation and that they are tightened to the manufacturer’s specifications.

Its combination of copper conductor quality, 90°C rating, flame retardant properties, and RoHS/CE/UL certifications, along with flexible length options (3 m, 5 m, 7 m), provides reliable performance across a range of domestic and commercial applications. The blue insulation aids color-coding and ease of identification in mixed wiring setups.
