Coast 4.0mm Twin W/E
The Coast 4.0mm Twin Cable functions as a high-performance electrical conductor for fixed power installations. It features two insulated cores and a central uninsulated earth wire. Engineers specify this gauge for circuits requiring higher current capacity than standard 2.5mm cabling. Each conductor uses high-purity annealed copper to ensure low resistance. This reduces thermal build-up during sustained high-load operations. The grey PVC outer sheath provides robust protection against mechanical abrasion. It complies with BS 6004 standards for domestic and industrial wiring. The internal insulation utilizes color-coded PVC for easy identification. This cable supports radial power distribution for heavy-duty appliances. It maintains structural integrity in various environmental conditions.
The 4.0mm² cross-sectional area allows for significant current throughput. It handles up to 37 Amps when clipped directly to a surface. This makes it suitable for electric showers and water heaters. The stranded copper construction offers enough flexibility for easy routing through conduits. It resists chemical degradation from common building materials like plaster or cement. The circuit protective conductor ensures a reliable path to ground. Technicians must apply green and yellow sleeving to the bare earth wire. This ensures compliance with standard safety labeling. The cable operates safely at voltages up to 500V. It withstands ambient temperatures up to 70 degrees Celsius.
The manufacturing process focuses on precise conductor alignment. This ensures uniform insulation thickness throughout the cable length. Consistent dielectric strength prevents electrical breakdown under surge conditions. The outer jacket is easy to strip during termination. This reduces installation time for large-scale projects. The cable is supplied in bulk lengths for project efficiency. It meets all relevant fire safety requirements for fixed installations. Additionally, the cable undergoes rigorous dielectric testing to ensure insulation integrity. This product provides a balance of durability and electrical efficiency. It remains a staple for professional electrical contractors.

Used this for the water heater wiring at my project in Kikuyu. My fundi was very happy with the gauge; he says it’s genuine copper unlike some of these cheap brands flooding the shops in town. It pulls through the conduits easily without the insulation peeling off. Definitely worth the price for the safety of the house.

Legit 4.0mm twin and earth. Verified the markings and it’s 100% original Coast. Good service.

The cable is definitely high quality and handles the load perfectly for my shower heaters. However, the outer grey sheath is quite stiff, which made it a bit of a struggle for the electrician to bend around the tight corners in the ceiling. Still, it’s a solid product and I trust the brand for safety.
