The 100m Roll of KEY 4B&S (20.29mm²) Twin Core Automotive Cable is designed for high-performance DC power applications where reliability, efficiency, and durability are essential. Featuring two insulated conductors within a single outer sheath, this premium twin core cable simplifies installation while providing a neat, professional wiring solution for automotive, marine, caravan, off-grid, and industrial electrical systems. Manufactured using Oxygen Free High Conductivity (OFHC) copper, it delivers superior current flow, reduced voltage drop, and dependable long-term performance.

About KEY Tubing & Electrical

KEY Tubing & Electrical (KTE) is an Australian-owned manufacturer with over 60 years of industry experience supplying electrical, cable, tubing, and custom-engineered solutions to industries across Australia and around the world. Based in South Australia, KEY is known for its commitment to quality manufacturing, rigorous quality standards, and reliable products designed for demanding automotive, electrical, industrial, and resource sector applications. KEY continues to support Australian industry with a strong focus on performance, durability, and dependable engineering.

Premium OFHC Copper for Maximum Conductivity

At the heart of this 4B&S twin core automotive cable is high-purity OFHC copper, which provides lower electrical resistance compared to standard copper conductors. This results in improved efficiency, reduced heat generation, and better voltage retention across longer cable runs. Whether powering battery systems, inverters, chargers, or auxiliary equipment, the cable helps ensure stable and consistent power delivery.

The flexible multi-strand conductor design also improves durability in environments subject to vibration, movement, and temperature fluctuations. This makes it ideal for installations in vehicles, boats, caravans, heavy machinery, and renewable energy systems where long-term reliability is critical.

Ideal for 12V, 24V and 48V Electrical Systems

With a conductor size of 20.29mm² per core (4B&S), this cable is commonly used for medium to high-current applications requiring both positive and negative conductors within a single cable assembly. The twin core design reduces installation time while providing additional protection against abrasion and environmental exposure. It is suitable for modern 12V automotive systems, 24V commercial vehicle installations, and 48V lithium battery applications.

Common Applications Include:

  • Dual battery systems in 4WDs and touring vehicles
  • Caravan and camper trailer battery installations
  • Marine battery banks and onboard electrical systems
  • DC-DC charger and battery charger wiring
  • Solar battery storage and off-grid power systems
  • Inverter installations and auxiliary power distribution

Built for Harsh Australian Conditions

Manufactured to comply with AS/NZS 1125 conductor standards and AS/NZS 3808:2000 insulation requirements, this cable is designed to handle the challenges of demanding automotive and industrial environments. The V90 insulation offers excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation.

The twin core construction keeps positive and negative conductors neatly contained within a durable outer sheath, helping to reduce cable clutter and improve protection. This makes it particularly popular for long cable runs between batteries, chargers, solar systems, and auxiliary equipment.

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love. I can’t wait to read the next one and to complete the series.

Fallen Angels, fae, vampires, oh my!
Format: Kindle
Rating: 4.5 | Spice: 2 (but a good slow-burn) • Main Characters: Huntyr and Wolf • I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆 We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger! • Emily, thank you for writing this awesome novel and I cannot wait to devour Book 2, Blood So Brutal! 😍 • Happy reading, my lovelies! xo

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.
