6242Y Twin & Earth Cable — BS 6004:2012, BASEC Approved 300/500V PVC Insulated Copper Cable for Domestic & Light Commercial Wiring
Overview
The 6242Y Twin & Earth cable is the industry-standard PVC-insulated, PVC-sheathed fixed wiring cable designed for residential, light commercial, and general building electrical installations across South Africa. Manufactured to BS 6004:2012 specifications, certified by BASEC, and produced under an ISO 9001 quality management system, this cable delivers consistent performance, durability, and compliance with recognised international standards — making it a trusted choice for electrical contractors, consulting engineers, and procurement specialists seeking reliable wiring solutions for South African homes, apartments, and small business premises.
Commonly specified in South African residential wiring projects, new housing developments, renovation work, and light commercial fit-outs, 6242Y Twin & Earth provides a safe, economical, and proven solution for all standard fixed wiring circuits. Its dual insulated current-carrying cores plus an uninsulated protective earth core ensure full earthing and compliance with best practice electrical safety — a critical consideration in South Africa, where reliable earthing and insulation performance help installations withstand varying climatic conditions and meet local electrical safety expectations.
Construction & Technical Specifications
Standard: BS 6004:2012
Voltage Rating: 300/500 V
Conductor: Plain annealed copper — solid conductors for 1.0 mm² to 2.5 mm² (for ease of handling and termination in standard domestic accessories); stranded conductors for 4.0 mm² to 16.0 mm² (improved flexibility for larger power circuits)
Insulation & Sheath: PVC insulation and overall PVC outer sheath — tough, moisture-resistant, and suitable for both dry and damp indoor environments commonly found in South African homes and buildings
Operating Temperature: -15°C minimum / +70°C maximum conductor operating temperature
Short Circuit Temperature: 160°C
Minimum Bending Radius: 8 × overall cable diameter — observe during installation to avoid damaging insulation or sheath
Certifications: BASEC Approved • CE Marked • ISO 9001 Manufactured
Installation & Application
6242Y Twin & Earth is intended for permanent fixed installation indoors. It may be:
Clipped directly to surfaces
Installed on cable trays or in free air — where it is not exposed to risk of heavy mechanical impact
Drawn into conduit or trunking — where additional mechanical protection is required
It is suitable for dry and damp internal premises. It is not intended for direct burial in the ground, direct exposure to sunlight, or outdoor use without additional protection. In South African practice, it is most commonly run in ceiling voids, under floors, within walls, or in surface-mounted trunking — protected from physical damage and weather.
Typical applications include:
Residential new-build wiring and renovation projects
Lighting circuits, power ring mains, and socket outlets
Fixed wiring for cookers, geysers/showers, and permanent appliances
Light commercial premises, offices, and retail units
Consumer unit and distribution board wiring
Size Selection & Technical Data
Choose the correct cross-sectional area based on circuit load, protection rating, voltage drop, and installation method — always verify against the latest wiring regulations and local municipal requirements.
