100 Metre Roll of KEY 6B&S Twin Core Automotive Cable for Reliable 12V, 24V, and 48V Power Distribution

High-Performance 13.5mm² Twin Sheath Cable for Caravans, 4WDs, Marine, and Off-Grid Systems

This 100-metre roll of KEY 6B&S (13.5mm²) twin core automotive cable delivers a professional-grade wiring solution for demanding low-voltage installations. Engineered with plain annealed oxygen-free copper conductors, it provides superior conductivity and minimal voltage drop over long cable runs, making it an excellent choice for caravan solar setups, 4WD dual battery systems, marine electronics, and off-grid power distribution. The twin core configuration, with red and black inner insulation, simplifies polarity identification and reduces installation time compared to running two separate single core cables.

Unlike generic automotive cable that may use copper-clad aluminium or lower-grade PVC, this cable features V90HT PVC insulation rated for continuous operation up to 90°C. The durable black outer sheath is UV-stabilised to resist degradation from prolonged sun exposure, ensuring long-term reliability in engine bays, under-vehicle routing, and outdoor environments. With a nominal current rating of 103A at 30°C (per JASO D609), it handles high-demand circuits such as inverters, battery chargers, and DC-DC converters with confidence. *Note typical de-rating factors apply for bundling and elevated ambient temperatures.

Why This Cable Outperforms Standard Options

Selecting the right cable is critical for safety and system efficiency. This 6B&S twin core cable addresses common pain points that installers face with inferior products:

  • Reduced Voltage Drop: The 13.5mm² cross-sectional area and high-purity copper minimise resistive losses, preserving battery voltage for sensitive electronics and maximising charging efficiency from solar panels or alternators.

Ideal Applications for 6B&S Twin Core Cable

This versatile cable is engineered for a wide range of low-voltage DC applications where reliability and performance are non-negotiable:

  • Caravan and RV Solar Systems: Connect solar panels to charge controllers and batteries with minimal power loss, even on longer roof-to-battery runs.
  • 4WD Dual Battery Setups: Link auxiliary batteries to isolators, fridges, and camping accessories with a cable that handles high current and harsh under-bonnet conditions.
  • Marine Wiring: Power navigation lights, bilge pumps, and onboard electronics with a moisture-resistant cable that withstands salt-laden air.
  • Off-Grid Cabins and Sheds: Distribute power from battery banks to inverters, lighting, and pumps in remote installations.
  • Automotive Lighting and Accessories: Upgrade headlight looms, driving light harnesses, or power inverters with a cable that exceeds standard OEM specifications.

Installation Considerations for Optimal Performance

To achieve the full 103A rating, install this cable in free air at an ambient temperature of 30°C. When bundling multiple cables or operating in hotter environments, apply the appropriate derating factors as outlined in JASO D609. For example, a bundle of three cables reduces the effective current rating to 70% of the nominal value, while an ambient temperature of 50°C requires a 0.76 multiplier. Always select the correct cable size based on your specific load, run length, and installation conditions. Consult a qualified auto electrician for complex installations to ensure compliance with relevant wiring standards.

Upgrade Your Power System with Confidence

Whether you're wiring a new caravan, upgrading a 4WD electrical system, or building an off-grid power setup, this 100-metre roll of KEY 6B&S twin core automotive cable provides the quality and performance needed for a safe, efficient installation. Add it to your cart today and power your next adventure with a cable built for Australian conditions.

Love that they come in a plastic container
I prefer this brand of razors because they don’t have the line sections on the blade. They are very sharp! Be careful. I love how sharp it is because I don’t need to do double passing on my face, and I can be as light as a feather with it and know it’ll still work. It did not cause any skin irritation, and was great at removing the dead skin cells off the top layer of my face.

Terrific!
While less well known than his later biographies of George Washington and Alexander Hamilton, this book stands equal to them. Rather than a biography of a single man this is the biography of a most extraordinary family and their impact on banking and the history of the twentieth century. This is a terrific book and one that I recommend without reservation. Chernow tells a very complex story in the tradition of a great novelist, without sacrificing any of the historical details that define the picture of a family whose story mirrors the triumphs and tragedies of the 20th century. The book traces the history of the Warburg family from the 16th century to the 1990's, with the emphasis on the 20th century. The story is told through the biographies of many of its members, focusing on the brothers Aby, Max, Paul, Felix and Fritz, their sons and nephews. Individual chapters cover individuals, interwoven and progressing through the 20th century. There is the scholarly eldest brother, Aby, who exchanged his birthright for the promise of being provided all the books he desired (and created one of the world's greatest private libraries), the next eldest brother Max who autocratically ran the familie's Hamburg bank, the next brother Paul who made his mark in the US (providing the banking expertise behind his idea for the US Federal Reserve System), Felix who also made his mark in the US (both as a banker, but even more so as a philanthropist) and on to the youngest Fritz who served in both the Prussian and American Armies, and eventually fought to revive the Warburg position as preeminent Hamburg bankers. The book follows these brothers and their nephew Sigmund who made his mark in the US, in Great Britain (becoming Sir Sigmund) and in Europe after WWII. The book also discusses the sons of these brothers, their wives and other relatives. Fortunately, there are several pages of genealogy charts which help in keeping all the relationships between family member straight and many photographs that help flesh out the many stories that are discussed. Were the book just about the history of the family members it would have been very good, but it is about much more. The book is about the turmoil of 20th century Germany, about how this family suffered and recovered. It is about family members who were loyal to their adopted homes in the US and Great Britain, but still, before the 1930's, had strong emotional ties to Germany. It tries to explain how some in the family still had warm feeling for Germany, in spite of what happened to them in the 1930's. It is about how Fritz left his comfortable life in the US to return to Germany to reestablish their stolen Hamburg bank, but also to serve as a bridge between Germany and the rest of the post-WWII world. It is about strong men with sons who often failed to live up to their high expectations. It is about loyalty, deceit, struggle, success and failure. It is a cautionary tail about the evolution of 20th century politics and war, as well as about banking. In short this is a terrific book.

I wish it had been done better
I imagine I'm going to get unhelpful votes by saying this, but this biography was not up to par with the author's other biographies. I've read Titan, which I thought was great, House of Morgan, which was really good, and Hamilton, which was also good, and this book just isn't up to those other books. The beginning was very frustrating because we learn about this supposedly very successful and widely acclaimed and established German banking family, yet there is practically nothing concerning how they got to be well known and exceedingly wealthy, nor what their business dealings were at the time. And this lack of information goes on and on, focusing almost to exclusion on inter-personal issues. Looking up the Warburgs in Wikipedia, I learned that the family had been a very successful banking family from the 1600's back in Venice, even before they settled in Warburg, Germany. Starting the narrative in the mid to late 1800's with the success of Jews in what was to become Germany just left me hanging and feeling like I was missing a large part of who the Warburgs were and how they got that way. Additionally, the family had been around for a very long time and there are scattered references to visiting or staying with uncles and aunts, but the overall breadth of the family is not addressed. Thinking about his problem now, it almost would make more sense and read better if there was a short intro and perhaps 10 separate bios on separate family members, instead of skipping around. It would help the flow. I have a feeling the author's inability to read German or Swedish or other European languages and his lack of primary research in Europe, where the Warburgs achieved fame and fortune, contributed to this incomplete biography. On the other hand, it appears that not much had been written on the Warburgs prior to this book (at least in English), and that is why I read the book. Additionally, the whole build up to the Holocaust and how the Warburgs kept their warm feelings for Germany throughout the experience, as a constant theme, was very interesting and well done, especially since I'm Jewish. The reading got more focused and poignant the closer the Holocaust got and immediately afterwards. 3 or 3.5 stars is probably the best score, but will upgrade so I don't get canned too badly. If you're interested in the Warburg it's a good starter book, though I imagine if this weren't one of the first books Chernow wrote, he would have done a better job as a more mature and accomplished biographer.

Well Worth the Lengthy Read

Enjoyed this book. Ron Chernow writes well, captures personalities and researches extensively. I went to Woodlands High School on an estate donated by the family. These were brilliant people who stood by their values and convictions while facing anti-semitism with grace and courage.
