OEX ACX0709 3mm Single Core Automotive Cable, Grey - 30m Roll

OEX ACX0709 Australian Made 3mm Single Core Automotive Cable Grey 30m Roll OFHC Copper 10A V90

The OEX ACX0709 is a 3mm single core automotive cable in grey, supplied on a 30m roll. Manufactured in Australia from 99.99% oxygen free high conductivity (OFHC) copper, it features a 1.13mm² conductor cross-section and a 10A continuous rating at 30°C, suited to higher-current accessory circuits, lighting runs and general automotive wiring. The grey PVC insulation is UV stabilised and rated to V90 (90°C). Compliant with AS/NZS 3808:2000 and RoHS.

Product overview

The ACX0709 is the grey 30m variant in the OEX 3mm single core automotive cable range, sharing the same conductor specification and insulation rating as the other colours in the range. Grey cable is used in automotive and trailer wiring installations as an additional circuit colour for complex multi-wire harness builds where the full standard colour set is already in use. It is also commonly used for specific sensor and signal circuit designations in automotive wiring conventions, providing a practical and distinctive identifier in installations requiring a broad colour palette at the 3mm gauge. At 1.13mm² (17AWG) with a 10A continuous rating, the ACX0709 handles higher-current circuits where the 2mm 5A-rated cable would be undersized.

The 16-strand conductor construction provides flexibility for routing through tight spaces and around bends. The UV stabilised V90 PVC insulation handles continuous operating temperatures up to 90°C for underbonnet and outdoor-exposed installations. The 30m roll suits workshop jobs and multi-circuit installations without the bulk of a full-length trade roll.

Features and benefits

99.99% 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.

Grey colour coding: Grey is used for specific sensor and signal circuit designations in automotive wiring, and provides an additional circuit identifier for complex multi-wire harness builds where the full standard colour set is already allocated.

10A rated at 30°C: Higher current capacity than the 2mm range, suited to lighting circuits, relay feeds, switch wiring and higher-draw accessory circuits in 12V and 24V systems.

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.

16-strand construction: The 16-strand conductor provides flexibility and resistance to fatigue during installation and in service.

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.

CAN bus compatible: Meets the signal integrity requirements for use in modern vehicle communication network environments.

30m roll: Workshop-friendly length for multi-circuit jobs without the bulk of a full-length trade roll.

Technical specs

Frequently asked questions

What is the difference between the 3mm and 2mm OEX automotive cable? The 3mm cable has a larger conductor cross-section (1.13mm² vs 0.5mm²), a higher amp rating (10A vs 5A at 30°C) and a higher voltage rating (110V vs 100V). It is suited to circuits drawing more current than the 2mm range can safely handle, including lighting circuits, relay feeds and higher-draw accessories.

What is the amp rating for this cable? This cable is rated at 10A 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.

Is this cable available in other colours or lengths? OEX produces single core automotive cable in a range of colours and roll lengths across both the 2mm and 3mm ranges. Contact us for available colour and length options to suit your specific wiring application.
