High-Performance 2.5mm² 3 Core Flexible Mains Cable for Mobile Environments

Building a reliable and safe 240V AC power system in a caravan, camper trailer, or marine vessel requires wiring specifically engineered to handle dynamic conditions. The Electra Cables 2.5mm² 2 Core + Earth Black Flexible Mains Cable delivers the structural integrity and electrical performance required for rigorous mobile applications. Sold by the metre to suit custom electrical layouts, this highly flexible cable ensures seamless power delivery for heavy-duty appliances, power outlets, and inverter systems.

This 2.5mm² cable is typically used for applications with a current rating of up to 20A. *Note typical de-rating factors apply based on installation conditions such as ambient temperature and conduit grouping.

Engineered for High-Vibration Applications

Traditional solid-core residential wiring is strictly unsuitable for mobile environments. Continuous vibration from corrugated roads or marine engine operation leads to metal fatigue, increasing the risk of structural cable failure and dangerous short circuits. This premium mains cable features finely stranded plain annealed copper conductors, granting it exceptional flexibility. By absorbing movement and chassis flex, it maintains robust electrical connections and significantly reduces the risk of long-term failure in custom van builds and off-grid tiny homes.

Durable 90°C Rated PVC Sheath

Routing cables through tight caravan roof cavities, automotive engine bays, or marine bulkheads exposes them to mechanical abrasion and high ambient heat. This 3 core flex cable addresses these risks with a heavy-duty black PVC outer sheath. Boasting a 1.1mm sheath thickness and a 10.2mm overall outer diameter, the insulation protects the internal active, neutral, and earth cores against environmental degradation. The elevated 90°C temperature rating ensures the cable continues to perform safely without melting or degrading when exposed to localized heat sources or peak summer temperatures.

Strict AS/NZS Compliance for Certified Installations

Electrical safety is critical, particularly when dealing with 240V AC systems in confined mobile spaces. To ensure your custom RV or boat wiring passes certified electrical sign-off, this flexible mains cable is manufactured to strictly comply with AS/NZS 3191, AS/NZS 1125, and AS/NZS 3808 standards. Additionally, the cable is Greenstar Approved, reflecting a commitment to environmentally responsible manufacturing without compromising on industrial-grade performance.

Key Features

• 3-core configuration featuring standard Brown (Active), Blue (Neutral), and Yellow/Green (Earth) cores
• Highly flexible stranded plain annealed copper to resist vibration fatigue in mobile setups
• Robust 10.2mm outer diameter PVC sheath providing excellent mechanical protection
• High-temperature rating up to 90°C for demanding automotive and marine installations
• Fully compliant with AS/NZS 3191, AS/NZS 1125, and AS/NZS 3808 for certified 240V AC work

Versatile Integration for Heavy-Duty Loads

With a voltage rating of 250/440V, this 2.5mm electric cable is highly capable of running demanding AC electrical loads. It is an excellent choice for wiring caravan air conditioning units, induction cooktops, high-output battery chargers, and general-purpose 10A or 15A power outlets (GPOs). The high flexibility not only ensures longevity but also vastly simplifies the installation process, allowing you to route the cable effortlessly around tight corners and through complex chassis framework.
