OEX ACX0799L 2mm Twin Core Automotive Cable, Red/Black, With Black Sheath - 100m Roll

Australian-Made Twin Core Automotive Cable for Lighting, Accessories, and Trailer Wiring One Cable, Two Conductors, Zero Compromise.

Product Overview

The OEX ACX0799L is a 100-metre roll of 2mm twin core automotive cable two conductors (red positive and black negative) enclosed in a single black outer sheath. Running both supply and return in one cable dramatically simplifies wiring for trailer lighting harnesses, automotive accessory circuits, auxiliary lighting runs, and any application where pulling a single neat cable is preferable to running two separate singles.

Made from Oxygen Free High Conductivity (OFHC) copper, rated to V90 (90°C), UV stabilised, and RoHS compliant, the ACX0799L meets the same premium material standards as the rest of the OEX Australian-made cable range. At 5A current capacity at 30°C, it is suited to low to moderate current loads trailer lighting, LED strip runs, accessory feeds, and general-purpose automotive signalling circuits.

Features & Benefits

• Twin Core Configuration — Red and Black in One Sheath — Two separately insulated conductors (red for positive, black for negative/earth) enclosed in a single black outer sheath. One cable run delivers a complete circuit — eliminating the need to route and secure two separate single-core cables and significantly reducing installation time on trailer harnesses and accessory wiring runs.
• Oxygen Free High Conductivity (OFHC) Copper — Less than 0.001% oxygen content minimises resistance, reduces oxidation over time, and ensures consistent current transfer across the full 100-metre roll. OFHC copper is the same specification used across the OEX 6 B&S single-core battery cable range — premium-grade conductor material at every gauge.
• 5A Rated @ 30°C — Confirmed current carrying capacity at 30°C ambient temperature. Suitable for trailer lighting circuits, LED accessory feeds, signalling wiring, and low to moderate current automotive applications. Note: current carrying capacity reduces at ambient temperatures above 30°C — confirm derating requirements with OEX for under-bonnet or high-heat installations.
• V90 Temperature Rating (90°C) — The insulation is rated to Australian Standard V90, withstanding sustained temperatures of 90°C — suitable for automotive environments including vehicle tray and trailer installations where ambient heat can be significant in Australian summer conditions.
• UV Stabilised Outer Sheath — The black outer sheath is UV stabilised to resist cracking, hardening, and degradation from prolonged sun exposure — important for cable runs on trailer chassis, caravan exteriors, and any above-deck or exposed routing in the Australian climate.
• RoHS Approved — Compliant with the Restriction of Hazardous Substances directive, confirming the cable is free from restricted materials including lead, cadmium, and mercury.
• 100% Australian Owned and Made — Manufactured in Australia to local quality standards, supporting local industry and ensuring material traceability for professional auto electricians and fleet operators who specify domestic product.
• 100-Metre Roll — Trade format suited to workshop supply, fleet wiring projects, and large-scale trailer harness builds. Buying in bulk ensures consistent cable specification across the entire job and reduces per-metre cost.

Frequently Asked Questions

What does twin core cable mean and why use it instead of two separate singles?

Twin core cable contains two separately insulated conductors — one red (positive) and one black (negative/earth) — inside a single outer sheath. Running one twin core cable instead of two separate single-core cables simplifies installation, reduces the number of cable management steps, and results in a neater, more professional finished wiring run.

What current can the ACX0799L carry and is it suitable for trailer lighting?

The ACX0799L is rated at 5A at 30°C ambient temperature — suitable for trailer lighting circuits, LED strip feeds, and low-current accessory wiring. Confirm that the total current draw of your circuit does not exceed 5A, and note that carrying capacity reduces at higher ambient temperatures.

Is this cable suitable for outdoor, exposed caravan, and trailer wiring?

Yes. The UV-stabilised black outer sheath and V90-rated insulation make the ACX0799L well-suited to outdoor, exposed cable runs on trailer chassis, caravan bodies, and vehicle trays — resisting UV degradation and the sustained heat common in Australian outdoor environments.

Why does the current rating matter at 30°C specifically?

Current carrying capacity is temperature-dependent. At higher ambient temperatures, cables carry less current safely before the insulation reaches its rated limit. The 5A rating at 30°C is the confirmed baseline — for installations in hotter environments, confirm the appropriate current limit with OEX or a licensed auto electrician.

Can this cable be used alongside the OEX 6 B&S single-core battery cables in the same installation?

Yes. The ACX0799L suits low-current signalling and lighting circuits, while the OEX 6 B&S single-core cables (ACX0902L black and ACX0903L red) handle high-current battery and primary power feeds. Using both in the same installation lets you match cable gauge precisely to each circuit's current requirements.
