OEX ACX0727L 4mm Single Core Automotive Cable, Blue - 100m Roll

OEX ACX0727L Australian Made 4mm Single Core Automotive Cable Blue 100m Roll OFHC Copper 15A V90

The OEX ACX0727L is a 4mm single core automotive cable in blue, supplied on a 100m roll. Manufactured in Australia from oxygen free high conductivity (OFHC) copper, it features a 1.84mm² conductor cross-section and a 15A continuous rating at 30°C, suited to higher-current lighting circuits, relay feeds, accessory wiring and general automotive applications where additional conductor capacity is required over the 3mm range. The blue PVC insulation is UV stabilised and rated to V90 (90°C). Compliant with AS/NZS 3808:2000 and RoHS.

Product overview

The ACX0727L is the blue 100m roll variant in the OEX 4mm single core automotive cable range, sharing the same conductor specification and insulation rating as the other colours in the range. Blue cable is used in automotive and trailer wiring for brake light feeds, indicator circuits and accessory runs, and assists with circuit identification in multi-wire installations where colour differentiation reduces wiring errors. At 1.84mm² (15AWG) with a 15A continuous rating, the ACX0727L handles higher-current brake light feeds and accessory runs where the 3mm 10A-rated cable would be undersized.

The 26-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 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.

Blue colour coding: Blue is used in automotive and trailer wiring for brake light feeds, indicator circuits and accessory runs, and assists with circuit identification in multi-wire installations where colour differentiation reduces wiring errors.

15A rated at 30°C: Higher current capacity than the 3mm range, suited to higher-output lighting circuits, relay feeds and heavier accessory loads in 12V and 24V systems drawing up to 15A.

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.

26-strand construction: The 26-strand conductor provides 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 4mm cable compare to 3mm and 2mm in the OEX range? The 4mm cable has a larger conductor cross-section (1.84mm²) and higher amp rating (15A at 30°C) than the 3mm (1.13mm², 10A) and 2mm (0.5mm², 5A) cables. Select the 4mm where circuits draw up to 15A, such as higher-output lighting, relay feeds or heavier accessory loads that would exceed the capacity of the 3mm range.

What is the amp rating for this cable? This cable is rated at 15A 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 the 2mm, 3mm and 4mm ranges. Contact us for available colour and length options to suit your specific wiring application.
