National Single Core Cable 4mm - Yellow

Conductor: stranded plain copper, Class 1 (BS EN 60228). Insulation: PVC with low smoke zero halogen (LSZH) qualities. Diameter: 4mm. Color: yellow. Features: flame retardant and heat-resistant, robust, flexible, suitable for power distribution, conduit wiring, control systems, instrumentation and switching.

It can be fixed in dry, moist, and wet interior premises and outdoors, making it versatile for domestic, commercial, and industrial installations.

LSZH insulation reduces smoke emissions and halogen content in the event of a fire, providing enhanced safety for users and helping to limit fire-related hazards.

Follow standard electrical practices: plan routes to avoid sharp bends, secure the cable with appropriate clips, respect minimum bend radii, maintain separation from high-heat sources, and ensure the system is de-energized during installation.

The cable uses Class 1 copper per BS EN 60228, with LSZH PVC insulation. It is flame retardant and designed to meet European safety standards for reliable and secure installations.

Ideal for low-voltage lighting circuits, signal transmission, power distribution in conduit wiring, control systems, instrumentation, and other fixed installations in domestic, commercial, and industrial environments.

Single-core cables are best for direct routes with simple layouts and are color-coded for identification. For applications requiring multiple conductors in a single sheath or different gauge options, compare with other National Core Cables on Fepy to match current rating, installation environment, and flexibility.

Gauge selection depends on the current carrying capacity required, installation conditions, and the length of the run. For higher current or longer runs, a larger cross-section or different cable type may be more suitable. Always match the cable specification to the design requirements and applicable standards.

Store the cable in a clean, dry area away from direct sunlight and heat sources. Keep it wound neatly on a spool or reel. The yellow color helps identify circuit type or purpose at a glance, so maintain clear labeling and documentation for every installation run.

If you need to return or exchange, follow Fepy’s standard product return process as outlined on their site. Ensure the product is in sellable condition and accompanied by any required proof of purchase.
