6 B&S (13.5mm²) Red Single Core Automotive Cable: High-Current Wiring for 12V, 24V, and 48V Systems

Engineered for Demanding Automotive and Low-Voltage Applications

This 6 B&S (13.5mm²) red single core automotive cable is designed to deliver reliable power in 12V, 24V, and 48V DC systems, with a maximum voltage rating of 120V DC. Manufactured in Australia from high-conductivity oxygen-free plain annealed copper, it ensures minimal voltage drop and efficient current transfer across critical connections. The robust red PVC insulation is rated for continuous operation up to 90°C, providing excellent resistance to abrasion, oils, and fuels commonly encountered in engine bays and under-vehicle installations.

With a current rating of 103A at 30°C (per JASO D609), this cable is suited for high-demand circuits such as dual battery systems, inverter supply lines, winch power feeds, and solar charge controller connections in caravans, 4WDs, and marine setups. The fine multi-stranded construction (168/0.32mm) offers excellent flexibility, simplifying routing through tight spaces and reducing installation effort.

*Note typical de-rating factors apply for elevated temperatures and bundled installations.

Key Features

• 103A current rating at 30°C (JASO D609) for high-power circuits
• 13.5mm² conductor area (6 B&S) with 168 strands of 0.32mm plain annealed copper
• Red PVC insulation rated to 90°C, resistant to oil, fuel, and abrasion
• Maximum 120V DC rating, suitable for 12V, 24V, and 48V systems
• Australian made to meet stringent quality and safety standards
• RoHS compliant and manufactured to AS/NZS 3808

Why Quality Cable Matters

In low-voltage DC systems, undersized or inferior cables can cause significant voltage drop, leading to underperforming equipment, battery charging issues, and potential safety hazards. This 6 B&S cable, with its low electrical resistance of 1.4 ohm/km at 20°C, helps maintain system efficiency and reduces heat buildup under load. Unlike generic alternatives that may use copper-clad aluminium or lower strand counts, our oxygen-free copper construction ensures long-term reliability and corrosion resistance, even in harsh Australian conditions.

Applications

Ideal for a wide range of automotive and off-grid energy projects:

• Dual battery isolator and management systems
• High-current alternator and starter motor wiring
• Inverter and DC-DC charger connections
• Solar panel to regulator cabling
• Winch and compressor power supply
• General low-voltage wiring in caravans, motorhomes, and boats

Installation Notes

For optimal performance, select the appropriate cable length and gauge based on your system's current draw and allowable voltage drop. Always use quality crimp terminals and consider protective conduit when routing through metal panels or high-abrasion areas. While this cable is rated for 103A, de-rating factors must be applied when multiple cables are bundled or ambient temperatures exceed 30°C. Refer to the provided de-rating tables or consult a qualified auto electrician for complex installations.
