Description
OEX ACX0808L Australian Made 4mm Twin Core Sheathed Automotive Cable Red and Black with Black Outer Sheath 100m Roll OFHC Copper 15A V90
The OEX ACX0808L is a 4mm twin core sheathed automotive cable supplied on a 100m roll. Red and black conductors are enclosed in a common black PVC outer sheath, rated at 15A continuous at 30°C and built to AS/NZS 3808:2000. Each conductor uses 26-strand 0.3mm oxygen free high conductivity (OFHC) copper construction with a 1.84mm² cross-section. The PVC insulation and sheath are UV stabilised and rated to V90 (90°C). RoHS compliant. Covered by a one year warranty. Weighs 5.7kg.
Product overview
The ACX0808L is the 100m roll version of the ACX0808 4mm twin core sheathed cable, suited to workshops and trade installers running full vehicle wiring harnesses, complete caravan fit-outs or bulk workshop stock, where the full 100m trade-length supply is preferred over the 30m workshop roll. The conductor specification, insulation rating and sheath construction are identical across both roll lengths. Red and black conductors are routed and protected together in a single black outer sheath, simplifying installation and reducing cable management complexity while protecting both conductors from abrasion, UV and moisture.
At 1.84mm² (15AWG) per conductor with a 15A continuous rating, the ACX0808L suits auxiliary lighting circuits, caravan and motorhome 12V accessory wiring, marine accessory circuits, dual battery system feeds and general 12V and 24V vehicle accessory installation. The V90 temperature rating and UV stabilised construction make it suitable for underbonnet environments, external routing on roof racks and chassis rails, and the demanding Australian conditions of coastal salt air, high UV and elevated ambient temperatures. Always derate for ambient temperatures above 30°C. The 15A rating also defines the correct inline fuse size — protect this cable with a maximum 15A fuse at the power source end of the circuit.
Features and benefits
OFHC copper for maximum conductivity and minimum resistance: Oxygen free high conductivity copper eliminates the oxygen inclusions that reduce conductivity in standard copper cable. Lower resistance means less voltage drop over length and less heat generation at rated current, both critical in automotive circuits with long cable runs.
Sheathed twin core construction: Red and black conductors enclosed in a black outer sheath route and protect both conductors together in a single cable run, simplifying installation and reducing cable management complexity over running two separate singles.
Red and black conductors: Conventional polarity colouring for straightforward positive and negative identification without additional marking or tape.
Australian owned and made: Premium quality copper cable produced locally to Australian automotive wiring standards.
15A rated at 30°C per conductor: Suited to auxiliary lighting circuits, caravan accessory feeds, marine wiring and general 12V and 24V two-wire circuits drawing up to 15A per conductor. Always derate for elevated ambient temperatures above 30°C.
V90 temperature rating (90°C): Insulation and sheath rated for continuous operation at up to 90°C, suited to underbonnet environments and high-temperature automotive applications including roof-mounted solar runs in Australian summer conditions.
UV stabilised PVC insulation and sheath: Resists degradation from prolonged sun exposure, suited to external routing on roof racks, chassis rails and caravan and motorhome builds where UV exposure is ongoing.
26-strand construction per conductor: 26 strands of 0.3mm wire per conductor provide flexibility and vibration resistance suited to the constant movement and vibration experienced by wiring in a vehicle, reducing the risk of work-hardening and fracture compared to lower-strand-count conductors.
AS/NZS 3808:2000 compliant: Meets the Australian and New Zealand standard for automotive cable construction, insulation and performance, suited to trade installations, compliance-sensitive builds and registered vehicle and caravan wiring.
RoHS compliant: Meets hazardous substance restrictions.
100m roll: Full project and bulk supply format suited to complete vehicle wiring harnesses, caravan fit-outs and workshop bulk stock without needing to join rolls mid-project.

Frequently asked questions
What is the difference between the ACX0808 and the ACX0808L? Both are the same 4mm twin core sheathed cable with identical conductor and insulation specifications. The ACX0808 is supplied on a 30m roll and the ACX0808L is supplied on a 100m roll. Select based on the quantity required for your installation workload.
What does OFHC copper mean and why does it matter? OFHC stands for oxygen free high conductivity copper. Removing oxygen from the copper during manufacturing increases conductivity and reduces resistance compared to standard copper cable. For automotive wiring, this means lower voltage drop over long cable runs and reduced heat generation at rated current.
What is the current rating and does it change with temperature? The ACX0808L is rated at 15A continuous at 30°C ambient. In higher ambient temperatures such as underbonnet or enclosed spaces in Australian summer conditions, the current carrying capacity reduces. Derate to a lower current limit for elevated-temperature applications or consult a licensed auto electrician.
What fuse size should I use with this cable? This cable is rated at 15A at 30°C. Protect it with a maximum 15A inline fuse at the power source end of the circuit. Using a larger fuse defeats the protection the fuse provides for the cable.
Is this cable compliant for professional auto electrical installations in Australia? Yes. The ACX0808L complies with AS/NZS 3808:2000, the Australian and New Zealand standard for automotive cable. This makes it appropriate for professional auto electrical installations, trade workshops and compliance-sensitive builds including registered vehicles and caravans.
