Description Automotive Thin Wall Cable – Flexible Vehicle Wiring Our automotive thin wall cable is designed for modern vehicle electrics where reliability, flexibility, and space-saving are important. Suitable for cars, vans, campervans, caravans, motorhomes, and 12–24V systems. What does mm² mean? (Simple explanation) The mm² size tells you how much copper is inside the cable. If you cut the cable and looked at the end: The copper area is measured in square millimetres (mm²) Bigger mm² = more copper More copper = the cable can carry more current (amps) ⚠️ Please note:mm² is NOT the same as diameter.The outside diameter of the cable is always larger because of the insulation.All our cables are specified by mm² (copper size). Simple comparison:Think of electricity like water in a pipe: Small mm² = narrow pipe (less power) Large mm² = wide pipe (more power) Overall Cable Diameter Guide (Thin Wall) Use this table if you are measuring an existing cable with a ruler or verniers. Cable size (mm²) Typical outside diameter 1.0 mm² ~ 2.0 mm 2.0 mm² ~ 2.6 mm 4.0 mm² ~ 3.3 mm 6.0 mm² ~ 3.8 mm 10 mm² ~ 4.8 mm 16 mm² ~ 6.0 mm 35 mm² ~ 9.5–10.0 mm Sizes are typical for automotive thin wall cable and may vary slightly by manufacturer. How to measure your existing cable Measure across the outside of the insulation Do not squash the cable Compare your measurement to the table above Choose the closest match �� The mm² refers to the copper inside, but measuring the outside diameter is the easiest way to identify your cable size. Why choose thin wall cable? Thinner insulation than standard automotive cable Same copper size, smaller overall diameter Saves space in looms and conduits Lightweight and easy to route Key features High-quality multi-strand copper for flexibility Heat-resistant automotive insulation Resistant to oil, fuel, and vibration Suitable for 12V and 24V systems Easy to strip and terminate Professional OEM-style cable Typical uses Lighting circuits Switches and relays Fans, pumps, and accessories Sensors and control wiring Campervan and caravan installations Choosing the right size Smaller mm² → lights, signals, low-power circuits Larger mm² → motors, accessories, battery feeds If in doubt, choose the next size up — especially for long cable runs. Flexible and durable. Sold by the meter in one continuous length.
