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
  • Marine battery and power distribution circuits
  • Off-grid solar and battery storage projects
  • Industrial low-voltage DC power applications

Installation Recommendations

For best results, ensure cable sizing is matched to the current demand and total cable run length of your system. Use quality crimp lugs, terminals, and appropriate circuit protection devices to maximise performance and safety. Protective conduit is recommended in areas subject to excessive abrasion or where cables pass through metal panels.

Build a Reliable Power System with Confidence

The 4 B&S (20.29mm²) Twin Core Automotive Cable per metre delivers the conductivity, durability, and flexibility required for modern high-current DC installations. Ideal for caravan, RV, marine, off-grid, industrial, 4WD, and battery storage applications, this premium twin core cable helps ensure efficient and dependable power delivery wherever your next project takes you. Order online today and upgrade your electrical system with professional-grade wiring built to last.

Absolute game changer for chronically dry feet/cracked heels
Size: S (up to size 7)-Beige
I had recently bought a pair of silicone heel/ankle wraps to fill out my boot a little since I noticed my heels were lifting when I was skating. I tested them out around the house and noticed they left my heels softer while the rest of my sockless feet got quite dry. So I got these full foot silicone socks to see the effect of having my whole foot covered. I slather the entirety of my feet with Dr. Scholl's Severe Cracked Heel Restoring Balm (love how convenient it is to apply it to my feet with the solid stick form) and then slip them into these silicone socks. After just a couple hours, when I pull out my feet they're (a teeny bit sweaty at first), but then overall soft and smooth and have absorbed the balm fully leaving barely any residue in the silicone sock. I find these silicone socks generally comfortable; I wear them in the evenings while relaxing on the couch, take them off after a couple hours and let my feet breathe a bit, and then reapply my balm and socks and wear them to bed. If I wake up in the middle of the night, which I almost always do (not because of the socks), I'll take the socks off and allow my feet to breathe again. I wear a woman's size 6 shoe and the small size is pretty comfortable. However, I made the mistake of wearing them while being on my feet for a couple hours straight during household chores -- they must've somehow cut off my circulation a bit with the standing, so I wouldn't recommend wearing these silicone socks while being active. And since they're not exactly my foot size, they slide around sometimes and will start to feel tight at my big toe. But if that happens, I just tug on the toe area of the sock to give my big toe more wiggle room and problem solved. Prior to wearing these socks, I was soaking and doing heavy duty exfoliation of my feet every week. These socks seem like they'll work to help me extend the time between soakings and exfoliations. The 5 pack is a great value. So far none have torn, so they seem rather durable. Not sure what I could even do to tear a hole in these.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?: I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them. The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.

Fantastic. I put lotion on my feet & wear them when I go to sleep. I often wake up during the night and will remove them to find my feet soft and smooth. They are strong and fit my size 10 womens’ size.
