Heavy-Duty Twin Core Automotive Cable for Reliable Power and Earth Connections

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.

Best paste and taste
Every once in a while you run into a product of true quality. Time is expensive currency so we’ll keep it concise. This is the best tooth paste we’ve ever tried. All good quality ingredients fluoride free. First thing we noticed is how quick it works, it cleans your teeth super quick used with electric toothbrush cutting brushing time considerably. Leaves mouth feeling clean and smooth plus great taste. A lot of new advanced products in self care tend to have chemical type scents and textures but this tooth paste has a pleasant feel and taste, we got coco ginger. Will buy again.

Tastes great, works great
I love this toothpaste! I’m so happy to have a toothpaste that isn’t mint-flavored. FLAVOR: The taste and smell are so good — the coco ginger flavor is delicious and I legitimately look forward to the taste of it. I was worried that the ginger might be strong/spicy, but it’s nicely balanced. The lavender lemon flavor is also pretty good, like a lemon pastry. The elamint flavor tastes like regular mint toothpaste, just maybe slightly more herbal. SENSITIVITY: I’ve had to use sensitive toothpaste for many years. Any time I switched off it, I would start experiencing sensitivity again within a week or so. I’m really happy to report that this toothpaste offers great sensitivity and enamel protection. WHITENING: I don’t feel that this toothpaste is contributing much in terms of whitening. My previous toothpaste had gentle whitening, and I do feel like I could tell it was working. While my teeth haven’t gotten less white since I switched to Boka, I don’t think they’ve gotten any whiter either. That’s okay with me — the flavor and sensitivity protection are worth it, and I can always do a whitening treatment in the future if I ever feel I need to. TEXTURE: The texture is just like normal toothpaste and brushing with it feels the same as any other toothpaste. It works great with both my manual toothbrush and my electric toothbrush. TUBE: The tube is really nice and sturdy. I like the design of the tube a lot. The text and color scheme are fairly minimalist, and I like that the cap has a wide base so the tube can stand upright. It looks nice on my bathroom shelf. My only small complaint is that it gets harder and harder to squeeze the toothpaste out once the tube is less than half full. Since the tube is so sturdy, it can’t be rolled and folded to get the paste out. I think this issue could probably be resolved easily with one of those squeezing tools, though. I’ll report back if I try it. SIZES: I love that it’s available in both a regular size and a little travel size. I also loved that the travel size allowed me to try out this toothpaste before committing to a whole large one. (Don’t worry, the tube in my photos was full when it arrived! I’ve used half of it.) Overall I highly recommend this toothpaste! I will absolutely buy it again.

Taste Great
This is a great tasting all natural toothpaste that actually does what it claims. My teeth feel so clean and fresh after brushing and the whitening is immediately noticeable, something that caught me by surprise. It's super easy to use and functional like any other toothpaste but without all the foaming at mouth. The ingredients are natural and it's fluoride free. I was looking for more of the ginger to come through but sadly it's hardly noticeable. I do like it but will try the other flavors next time.

Favorite toothpaste! Love the Ginger Flavor
This is my favorite toothpaste! I have very sensitive teeth and this has improved that sensitivity quite a bit. I like that Boka offers many different flavors that aren't typical "kid flavors." I know some folks, especially neurodiverse, are averse to mint and the ginger is nice and refreshing without being overpowering. Nano toothpaste is easy to use, doesn't require water even, and is a nice consistency like a gel. No gritty feeling like with typical toothpaste. My dentist was please with my teeth last time I visited after using for 6 months, so it's doing what it's supposed to do.
