OEX ACX0905 4 B&S Single Core Battery Cable, Red - 30m Roll

OEX ACX0905 Australian Made 4 B&S Single Core Battery Cable Red 30m Roll OFHC Copper 20.29mm² V90

The OEX ACX0905 is a 4 B&S single core battery cable in red, supplied on a 30m roll. With a 20.29mm² OFHC copper conductor across 287 strands, this is one of the largest cables in the OEX battery cable range and is designed for the most demanding high-current positive supply applications including heavy-duty battery interconnects, high-capacity winch feeds and commercial vehicle wiring where maximum current-carrying capacity and minimum resistance are required. The red insulation colour suits positive supply runs in conventional automotive wiring colour coding. The PVC insulation is UV stabilised and rated to V90 (90°C). Compliant with AS/NZS 3808:2000 and RoHS. Covered by a one year warranty.

Product overview

The ACX0905 is the red variant of the OEX 4 B&S single core battery cable range, sharing the same conductor specification and insulation rating as the black ACX0904. Red is the conventional positive wiring colour in automotive and marine electrical installations, making the ACX0905 the natural choice for battery positive supply cables, dual battery main positive feeds on high-draw setups, high-capacity winch power cables and commercial vehicle starter motor and alternator positive leads where maximum conductor cross-section is required.

At 20.29mm² with a 287-strand OFHC copper conductor, the ACX0905 provides significantly lower resistance and higher current-carrying capacity than both the 6 B&S (13.36mm²) and 8 B&S (7.91mm²) cables. The 287-strand construction delivers outstanding flexibility for routing through tight engine bay and battery compartment spaces despite the very large cable gauge. The UV stabilised V90 PVC insulation handles continuous operating temperatures up to 90°C for battery and engine bay installations. The 30m roll suits workshop jobs and single-vehicle installations. Always verify the required cable size with a licensed auto electrician for your specific application, current load and run length.

Features and benefits

4 B&S gauge battery cable: Heavy-duty battery cable for the most demanding high-current 12V and 24V positive supply applications, stepping up from the 6 B&S range for long runs, very high current draws and commercial vehicle wiring.

Red colour coding for positive supply runs: Red is the conventional positive wiring colour in automotive and marine electrical installations, assisting with circuit identification and reducing wiring errors in high-current battery supply circuits.

20.29mm² conductor cross-section: Significantly larger than 6 B&S (13.36mm²) and 8 B&S (7.91mm²), providing the lowest resistance and highest current-carrying capacity in the OEX battery cable range.

287-strand construction: Outstanding flexibility for routing through tight engine bay and battery compartment spaces despite the very large cable gauge.

OFHC copper conductor: Oxygen free high conductivity copper minimises resistance for efficient current transfer across the most demanding battery and positive supply circuit applications.

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

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

V90 temperature rating (90°C): PVC insulation rated for continuous operation at up to 90°C, suited to battery and engine bay installation environments.

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.

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

Technical specs

Frequently asked questions

What is B&S gauge and how does it differ from AWG or metric sizing? B&S (Brown and Sharpe) is a wire gauge system commonly used in Australian battery and heavy-duty automotive cable. 4 B&S is equivalent to approximately 4 AWG and corresponds to a conductor cross-section of around 20.29mm². It is a standard sizing reference used by Australian auto electricians and suppliers for battery and starter cables.

How does 4 B&S compare to 6 B&S and 8 B&S? 4 B&S has the largest conductor cross-section (20.29mm²) of the three, compared to 6 B&S (13.36mm²) and 8 B&S (7.91mm²), giving it the lowest resistance and highest current-carrying capacity. Select 4 B&S for the most demanding applications including long runs, very high current draws and commercial vehicle wiring. Always verify the correct cable size with a licensed auto electrician for your specific application.

How does the ACX0905 differ from the ACX0904? Both are 4 B&S single core battery cables with identical conductor and insulation specifications. The ACX0904 is black and suits earth and negative runs. The ACX0905 is red and suits positive supply runs. Select based on the polarity convention of your installation.

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 battery and engine bay installation positions.
