Whether you are running a heavy-duty line for a large motorhome or caravan, assembling a high-amperage custom extension lead, or powering large marine equipment, this British Standard approved cable is the ultimate safe choice for professional-grade DIY builds.
Why Choose 4.0mm² Arctic Blue Flex?
- Easy to Buy (Per Metre): Avoid paying for expensive, bulky full-sized drums. Get the exact measurement your project needs.
- Stays Pliable in Severe Cold: Unlike standard PVC cables that become brittle and fracture in freezing winter weather, this specialized Arctic-grade sheath remains completely soft and easy to coil down to -40°C.
- High Visibility Safety: The bright blue outer jacket is the standard visual code required to denote 240V power lines, critical for site safety regulations and easily visible on grass or tarmac.
- Thick 4.0mm² Cores for Higher Power: Built with high-purity, Class 5 fine stranded flexible copper wires. The thicker 4mm² diameter safely handles significantly more current than standard 1.5mm² cables, eliminating voltage drop over longer distances.
Perfect For Your Higher-Load Projects
This heavy-duty, high-amperage cable is highly recommended for tasks that require superior power delivery:
- Large Motorhomes & Marine Hookups: Perfect for high-demand luxury caravans, motorhomes, and boats that require a beefier 32A power supply hookup.
- High-Capacity Extension Leads: Build high-amperage, customized 240V extension cords for power-hungry catering equipment, event setups, or heavy workshop tools.
- Temporary Outdoor Infrastructure: Ideal for temporary event power distribution, outdoor generators, and marquee lighting arrays operating in harsh winter climates.
