OEX ACX0902L 6 B&S Single Core Battery Cable, Black - 100M Roll

Premium Australian-Made Earth and Negative Cable for Dual Battery, 4WD, and Auto Electrical Builds.

Product Overview

The OEX ACX0902L is a 100-metre roll of 6 B&S single-core black battery cable designed for earth, negative, and return-path wiring in high-current automotive and electrical applications. Made from Oxygen Free High Conductivity (OFHC) copper, it delivers superior conductivity and oxidation resistance compared to standard copper cable critical in dual battery systems, caravan power circuits, and high-output car audio installations where a solid earth path is just as important as the positive feed.

Rated to V90 (90°C) and UV stabilised, the ACX0902L handles the sustained heat and sun exposure common to Australian under-bonnet and 4WD touring environments. RoHS compliant and Australian owned and made, it pairs directly with the OEX ACX0903L red 6 B&S cable for a matched positive and negative installation using a single trusted product range.

Features & Benefits

• Oxygen Free High Conductivity (OFHC) Copper — With less than 0.001% oxygen content, OFHC copper minimises electrical resistance, resists internal oxidation, and ensures consistent current transfer across the full 100-metre roll — important for earth and negative runs where poor conductivity leads to voltage drop, heat build-up, and system instability.
• V90 Temperature Rating (90°C) — Rated to Australian Standard V90, the insulation withstands sustained under-bonnet temperatures and the heat generated by high-current loads in enclosed battery boxes and wiring runs — a must-have spec for professional Australian auto electrical work.
• Voltage Rating up to 120V — Covers all standard 12V and 24V vehicle systems with substantial headroom, as well as low-voltage solar, caravan, and marine power applications.
• UV Stabilised — The black insulation is UV stabilised to resist cracking, hardening, and degradation from prolonged sun exposure — critical for any above-deck, rooftop, or exterior cable run in the Australian climate.
• RoHS Approved — Compliant with the Restriction of Hazardous Substances directive, confirming the cable is free from restricted materials including lead, cadmium, and mercury.
• 100% Australian Owned and Made — Manufactured in Australia to local quality standards, supporting local industry and ensuring full traceability for professional auto electricians and fleet operators who specify domestic product.
• 100-Metre Roll — A full-roll trade format suited to workshop supply, fleet fitouts, and large-scale installations. Buying in bulk ensures consistency of gauge and insulation spec across the entire job.

Frequently Asked Questions

What is 6 B&S cable used for in automotive applications?

6 B&S (Brown & Sharpe) is a heavy-gauge cable suited to high-current applications including dual battery earth runs, amplifier negative feeds, winch wiring, and chassis earth connections. Confirm current carrying capacity with OEX to match it to your specific circuit requirements.

Why is the earth cable as important as the positive cable in a dual battery system?

A high-resistance earth path causes voltage drop, heat build-up, and unreliable circuit performance. Using the same quality OFHC copper cable for both positive and negative runs ensures a balanced, low-resistance circuit throughout your installation.

Does this cable pair with the OEX ACX0903L red battery cable?

Yes. The ACX0902L black and ACX0903L red are matching 6 B&S OFHC cables from the same OEX range, designed to be used together for positive and negative wiring in a consistent, professionally matched installation.

What does the V90 temperature rating mean for under-bonnet use?

V90 is an Australian Standard designation indicating the cable's PVC insulation is rated to a continuous operating temperature of 90°C — suitable for under-bonnet environments and enclosed wiring runs where ambient and load-generated heat is sustained.

Is this cable suitable for solar and caravan off-grid power systems?

Yes. The 120V voltage rating, UV-stabilised insulation, and V90 temperature tolerance make the ACX0902L well-suited for solar, caravan, and off-grid power system earth and negative wiring. Confirm current carrying capacity for your specific cable run length with OEX or a licensed auto electrician.
