4B&S (20.29mm²) Twin Core Automotive Cable per Metre
Heavy-Duty Twin Core Cable for High-Current 12V, 24V and 48V DC Applications
The 4 B&S (20.29mm²) Twin Core Automotive Cable is designed for demanding automotive, caravan, RV, marine, off-grid, industrial, and battery storage applications where reliable power delivery and simplified installation are essential. Featuring both positive and negative conductors within a single durable sheath, this premium twin core cable provides a neat, professional wiring solution for high-current DC systems.
Manufactured using high-conductivity oxygen-free annealed copper, this cable delivers excellent electrical efficiency with reduced voltage drop across longer cable runs. The flexible multi-strand construction allows for easier routing through vehicles, trailers, boats, and off-grid installations while maintaining the durability required for harsh operating environments.
Engineered for Reliable Power Transfer
Whether you're installing a dual battery system, powering a high-capacity inverter, connecting a DC-DC charger, or wiring a complete off-grid battery bank, this 20.29mm² twin core cable is built to handle substantial current loads. By incorporating both conductors into a single cable assembly, installation time is reduced while providing improved cable protection and a cleaner finished result.
The heavy-duty insulation is designed to withstand exposure to oil, fuel, abrasion, vibration, and demanding environmental conditions commonly encountered in automotive and marine applications. This makes it an ideal choice for professional installers and DIY enthusiasts seeking dependable long-term performance.
- 20.29mm² (4 B&S) twin core cable for high-current applications
- Oxygen-free annealed copper conductors for maximum conductivity
- Flexible multi-strand construction for easy installation
- Positive and negative conductors within a single protective sheath
- Suitable for 12V, 24V and 48V DC electrical systems
- Resistant to oil, fuel, abrasion, and harsh operating conditions
Reduce Voltage Drop in Critical Circuits
Voltage drop can significantly impact the performance of batteries, chargers, inverters, and other electrical equipment in low-voltage systems. The large 20.29mm² conductors help minimise power losses over long distances, making this cable an excellent choice for battery-to-battery charging systems, inverter installations, solar power systems, and auxiliary power circuits.
Using a quality twin core automotive cable not only improves system efficiency but also simplifies cable management by keeping both conductors protected within a single outer sheath. This reduces clutter, improves installation appearance, and provides additional mechanical protection compared to separate single-core cables.
Common Applications
- Dual battery and battery management systems
- DC-DC charger installations
- Inverter power supply connections
- Solar battery bank and charge controller wiring
- Caravan, motorhome, and RV electrical systems
