CABLE SINGLE 3.0 10AMP 7M BLUE

Narva cable is used for 12V wiring throughout a campervan — connecting batteries, fuses, switches, lights, and appliances. It uses oxygen-free copper for maximum conductivity and RoHS-compliant PVC insulation rated for automotive and marine environments.

The 3mm refers to the conductor cross-sectional area and the 10A is the continuous current rating. This size is suitable for lighting circuits, switches, USB chargers, and low-current accessories in a 12V campervan system. For higher current loads like fridges or inverters, use larger cable.

Colour coding makes wiring easier to trace and diagnose. In 12V systems, red is typically positive, black is negative, and other colours (blue, white, yellow, brown) are used for specific circuits such as lighting, accessories, and switched outputs. Consistent colour coding is essential for safe and maintainable van wiring.
