Austech - 8B&S (8mm²) Black Single Core Automotive Cable - Australian Made - Per Metre

High-Conductivity Single Core Automotive Cable for Demanding DC Power

Austech 8B&S (8mm²) Black Single Core Automotive Cable per Metre is a professional-grade single core automotive cable sold per metre for clean, efficient power delivery in 12V and 24V vehicle systems, and suitable for higher-voltage DC setups within its rating (up to DC 120V). Built with a high-strand copper conductor to AS/NZS 1125 and insulated for automotive environments, it’s designed to help reduce voltage drop and heat build-up in high-current circuits—particularly important when you’re running inverters, DC-DC chargers, dual battery systems, or long cable runs in caravans, 4WDs, marine and industrial installations.

In real-world installs, cable choice is often the difference between accessories that perform as expected and systems that feel underpowered. By using quality copper and a robust insulation system, this cable supports more stable voltage at the load, helping equipment operate within its intended input range. That translates to fewer nuisance low-voltage cut-outs, improved charging performance, and better overall system efficiency—especially when paired with correctly sized fusing and terminations.

Designed for Australian Conditions and Standards

This cable is manufactured to recognised Australian/New Zealand standards for conductor and insulation. The insulation is engineered for elevated temperatures typical of engine bays, canopies and enclosed compartments, while the fine-strand construction improves flexibility—making routing through tight spaces and around bends easier without compromising the integrity expected of automotive battery cable.

Where It Fits: From Battery Links to High-Draw Accessories

Use 8B&S (8mm²) Black Single Core Automotive Cable per Metre wherever you need dependable DC cabling with predictable performance. It’s commonly selected for starter and auxiliary battery connections, busbar feeds, winch and compressor circuits, and cabling between batteries and MPPT solar controllers or inverters. If your application involves 8B&S (8mm²) DC wiring or you’re chasing lower voltage drop over long vehicle and caravan cable runs, stepping up to the correct B&S size can make a measurable difference.

Note: The published current rating is based on a 100% duty cycle at 30°C (JASO D609). In practice, maximum current may be reduced by installation conditions such as ambient temperature, bundling, conduit, airflow, and run length—consider standard de-rating factors when sizing cable for continuous loads.
