When dependable power transfer is critical, the 100m Roll of KEY 3B&S (26mm²) Black Single Core Automotive Cable delivers the performance professional installers demand. Manufactured using Oxygen Free High Conductivity (OFHC) copper, this premium automotive cable provides exceptional conductivity, reduced voltage drop, and long-term durability in demanding automotive, marine, industrial, and off-grid environments. Designed to support high-current applications across 12V, 24V, and 48V electrical systems, it offers the ideal balance of flexibility, strength, and electrical efficiency.

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.

Superior Conductivity with OFHC Copper Construction

Unlike conventional automotive cables, this 26mm² single core automotive cable utilises high-purity OFHC copper to maximise current flow and minimise resistance. The reduced impurity content helps lower heat generation under load, improving overall system efficiency and reducing energy losses. Whether powering a dual battery setup, feeding a DC-DC charger, or supplying current to a high-capacity inverter, this cable helps maintain stable voltage delivery throughout the system.

OFHC copper also offers enhanced resistance to hydrogen embrittlement and mechanical fatigue. This makes it particularly suitable for installations exposed to constant vibration, temperature fluctuations, and harsh environmental conditions commonly encountered in 4WDs, caravans, commercial vehicles, marine vessels, and industrial equipment.

Designed for High-Current 12V, 24V & 48V Systems

The substantial 26mm² conductor size, commonly referred to as 3B&S automotive cable, is ideal for applications requiring dependable high-current performance over longer cable runs. Rated for a maximum DC voltage of 120V, it is perfectly suited for modern vehicle electrical systems, lithium battery installations, inverter circuits, auxiliary battery banks, and renewable energy systems. The cable's low-resistance construction helps minimise voltage drop, making it an excellent choice for demanding power distribution applications.

Common Applications Include:

  • Dual battery systems in 4WDs, caravans and camper trailers
  • Battery interconnects and auxiliary battery wiring
  • DC-DC charger installations and lithium battery systems
  • High-current inverter and solar power systems
  • Marine electrical systems and battery banks
  • Commercial vehicle, fleet and industrial power distribution

Built to Australian Standards for Long-Term Reliability

Manufactured to comply with AS/NZS 1125 conductor requirements and AS/NZS 3808:2000 insulation standards, this cable delivers dependable performance in demanding environments. The durable V90 insulation provides excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation through chassis rails, conduits, and tight engine bay spaces.

The black outer sheath allows clear identification for negative earth and grounding circuits while maintaining a professional appearance in automotive, marine, and industrial installations. Supplied in a convenient 100-metre roll, it is an economical solution for workshops, auto electricians, fleet maintenance operators, and large-scale wiring projects.

Basic hypochlorous acid
My family has used hypochlorous acid for a long long time for everything from cuts and scrapes to pink eye to sunburns to preventing mold and mildew in kid cups and showers. It’s an amazing solution to so many things and even makes an awesome hand sanitizer. Plus it’s safe for consumption so can be used on kid toys or directly on skin. Despite packaging differences they’re pretty much all the same if they’re pure hypochlorous acid. Like others this one is not greasy, has no fragrance and is lightweight. It is water based so it’s moisturizing and prevents infection. At a current price of $14 for 2 ounces this is on the higher end. I think the value is just okay and worth comparing other brands (check ingredients!) but this small size is very handy for throwing in a beach bag or purse.

A versatile hypochlorus acid product from a well-known company
This product is billed as an after-sun spray, but really, it is so much more. It is actually a hypoclorous acid product, and a quick Internet search will tell you all of its possible uses. To summarize, hypoclorous acid is a disinfecting and soothing agent that—unlike rubbing alcohol or hydrogen peroxide—is very gentle on the skin. This product came with both a foil seal and in tamper-proof packaging, which I appreciated. The bottle included a separate optional spray pump, so that you can dab it on with a cotton ball or q-tip straight from the bottle, or use the spray for an all-over application. The ingredients showed that the product is made from only three ingredients: water, salt, and hypochlorus acid. It smells a bit like swimming pool water, but every fragrance-free hypochlorus acid product is going to smell like this because hypochlorus acid itself has a very faint chlorine scent. There are many hypochlorus acid products on the market. This one worked fine, and came from a known name brand, unlike most of the other options out there that are manufactured by no-name brands. If you are looking for a brand name option, this is a good one. If you don’t care about that, there are likely better values out there.

Finally, a after-sun mist that actually does something
I was skeptical - three ingredients, simple packaging, no dramatic claims — After a long day in the sun my face was red and hot, and I did a split test: sprayed it on one half and left the other alone. The difference was visible within minutes. The treated side calmed down, the redness faded faster, and it just felt immediately soothed. I went back and sprayed the other half immediately. The active ingredient is hypochlorous acid, which is actually something your own immune system produces — it's antimicrobial and anti-inflammatory without being harsh or sensitizing. No alcohol, no fragrance, no parabens, no dye. Nothing on this ingredient list that has any business irritating already-angry skin. It's pH balanced and truly non-stinging, which matters a lot when your skin is compromised. I've also been using it on insect bites and it's become my first reach for anything red and irritated. It takes down the swelling and calms the area noticeably. Not a substitute for antihistamine if you're having a real reaction, but as an immediate soothing step it's excellent.
