Cable

High-Quality DC Automotive Cable for 12V & 24V Systems.

In any 12V or 24V electrical system, the quality and size of your wiring are just as important as the appliances they power. Using undersized or low-quality cable is a leading cause of voltage drop, which can prevent fridges from starting, cause LED lights to flicker, and even pose a fire risk due to overheating. At RV World, we supply OEX Twin Core Automotive Cable, specifically designed to handle the demands of the New Zealand RV and marine environments.

Choosing the Right Cable Size: 2mm to 6mm

Selecting the correct gauge (thickness) for your project depends on the current draw (Amps) of your appliance and the length of the cable run. We stock various sizes to suit every application:

• 2mm Twin Core: Ideal for low-draw applications like LED lighting circuits and USB charging ports.
• 4mm Twin Core: A versatile choice for medium-draw items such as water pumps, fans, and small 12V accessories.
• 5mm & 6mm Twin Core: Essential for high-demand appliances, including 12V compressor fridges, diesel heaters, and TV/Entertainment systems, especially over longer distances where voltage drop is a concern.

Twin Core Design for Professional Installations

Our OEX cable features a Twin Core configuration (positive and negative wires housed within a single outer sheath). This design is the industry standard for caravan and motorhome wiring because it provides an extra layer of protection against abrasion and makes for a much neater, more professional installation. Whether you are rewiring a classic campervan or adding a new circuit to your modern motorhome, using twin core cable ensures a reliable ground return and simplifies your cable management.
