OEX ACX0750L 5mm Single Core Automotive Cable, Black - 100m Roll

OEX ACX0750L Australian Made 5mm Single Core Automotive Cable Black 100m Roll OFHC Copper 20A V90

The OEX ACX0750L is a 5mm single core automotive cable in black, supplied on a 100m roll. Manufactured in Australia from oxygen free high conductivity (OFHC) copper, it features a 2.9mm² conductor cross-section and a 20A continuous rating at 30°C, stepping up from the 4mm range to handle higher-current circuits including heavy accessories, lighting systems and automotive wiring runs where greater conductor capacity is needed. The black PVC insulation is UV stabilised and rated to V90 (90°C). Compliant with AS/NZS 3808:2000 and RoHS.

Product overview

The ACX0750L steps up from the OEX 4mm range with a larger 2.9mm² (13AWG) conductor cross-section and a 20A continuous rating, suited to circuits where the 4mm 15A-rated cable would be undersized. Typical applications include heavy lighting systems, high-draw accessory circuits, relay and switch feed wiring, trailer and caravan wiring runs requiring additional capacity, and auxiliary power feeds drawing up to 20A. The 41-strand conductor construction provides flexibility for routing through tight spaces and around bends, with more strands than the 26-strand 4mm cable for improved flexibility at this larger conductor size.

The UV stabilised V90 PVC insulation handles continuous operating temperatures up to 90°C for underbonnet and outdoor-exposed installations. Compliance with AS/NZS 3808:2000 confirms the cable meets defined requirements for conductor construction, insulation properties and performance under the Australian and New Zealand standard for cables used in the internal wiring of equipment. The 100m roll suits workshops and trade installers covering multiple jobs from a single roll.

Features and benefits

OFHC copper conductor: Oxygen free high conductivity copper minimises resistance and signal loss across the cable run, maintaining reliable electrical performance in automotive and marine applications.

Australian owned and made: Premium quality copper cable produced locally to Australian automotive wiring standards.

20A rated at 30°C: Higher current capacity than the 4mm range, suited to heavy lighting systems, high-draw accessory circuits and demanding auxiliary loads in 12V and 24V systems drawing up to 20A.

UV stabilised PVC insulation: Resists degradation in sun-exposed and underbonnet environments.

V90 temperature rating: PVC insulation rated for continuous operation at up to 90°C, the standard automotive-grade insulation specification in Australia.

41-strand construction: The 41-strand conductor provides excellent flexibility and resistance to fatigue during installation and in service, suited to routing through tight spaces and around bends.

AS/NZS 3808:2000 compliant: Meets the Australian and New Zealand standard for insulated conductors and cables for internal wiring of equipment.

RoHS compliant: Meets hazardous substance restrictions.

100m roll: Trade-length supply for workshops and fleet installers covering multiple jobs from a single roll.

Technical specs

Frequently asked questions

How does 5mm cable compare to the smaller sizes in the OEX range? The 5mm cable has a larger conductor cross-section (2.9mm²) and higher amp rating (20A at 30°C) than the 4mm (1.84mm², 15A), 3mm (1.13mm², 10A) and 2mm (0.5mm², 5A) cables. Select the 5mm where circuits draw up to 20A, such as heavy lighting systems, high-draw accessories or demanding auxiliary loads that would exceed the capacity of the 4mm range.

What is the amp rating for this cable? This cable is rated at 20A continuous at 30°C. Ampacity decreases as ambient temperature rises, so applications in high-heat environments such as underbonnet installations should be assessed against the expected operating temperature before use.

What does V90 mean? V90 is the Australian cable insulation classification indicating the PVC insulation is rated for continuous operation at up to 90°C. It is the standard specification for automotive-grade PVC insulated cable in Australia and confirms suitability for underbonnet and outdoor-exposed installation positions.

What does AS/NZS 3808:2000 compliance mean? AS/NZS 3808:2000 is the Australian and New Zealand standard covering insulated conductors and cables for internal wiring of equipment. Compliance confirms the cable meets defined requirements for conductor construction, insulation properties and performance.
