KEY 100 Metre Roll of 8B&S (7.9mm²) Twin Core Automotive Cable for Reliable 12V/24V Power Distribution

Engineered for Demanding Automotive and Low-Voltage Installations

This 100-metre roll of KEY 8B&S (7.9mm²) twin core automotive cable delivers consistent, low-resistance power for critical 12V and 24V systems. Built with plain annealed copper conductors and V90HT PVC insulation, it is suited to professional installers and enthusiasts wiring caravans, 4WDs, trailers, and marine setups. The twin core configuration simplifies cable runs by combining positive and negative conductors in a single durable sheath, reducing installation time and potential wiring errors.

Rated to 74A at 30°C under JASO D609, this cable handles high-current loads while maintaining voltage stability over long distances. It is commonly selected for 60A continuous-duty circuits such as auxiliary battery charging, inverter connections, and solar regulator wiring. The 100-metre bulk roll provides ample length for large-scale projects or multiple smaller installations, offering a cost-effective solution for workshops and fleet maintenance.

*Note typical de-rating factors apply for bundling and elevated ambient temperatures.

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.

Key Features

  • High-conductivity plain annealed copper minimises voltage drop and resistive heating
  • V90HT insulation rated to 90°C withstands under-bonnet and engine bay temperatures
  • UV-stabilised outer sheath resists degradation from prolonged sun exposure
  • RoHS compliant and manufactured to Australian/NZ standards for safety and reliability
  • 100-metre continuous length reduces joins and waste in extensive wiring runs
  • Red and black core identification simplifies polarity matching during installation

Built for Harsh Australian Conditions

The V90HT PVC insulation is formulated to endure the thermal cycling common in engine compartments, while the UV-stabilised black outer sheath prevents cracking and embrittlement when exposed to direct sunlight. This makes the cable suitable for external runs on camper trailers, roof-mounted solar wiring, and marine deck applications. The oxygen-free copper stranding (96/0.32mm) provides flexibility for routing through tight chassis spaces without compromising current-carrying capacity.

Unlike generic automotive cables that may use copper-clad aluminium or thinner insulation, this product maintains full copper cross-section and consistent wall thickness, reducing the risk of hot spots and insulation breakdown under sustained loads. The 2.4 ohm/km electrical resistance at 20°C ensures efficient power delivery, critical for maintaining battery health in dual-battery systems.

Applications

  • Auxiliary battery charging in 4WDs, caravans, and camper trailers
  • Solar regulator to battery connections for off-grid setups
  • Inverter cabling up to 1000W (12V) or 2000W (24V) with appropriate fusing
  • Trailer and boat wiring for lighting, winches, and electric brakes
  • General low-voltage distribution in sheds, tiny homes, and remote installations

Installation Notes

For optimal performance, select cable size based on total circuit length (positive and negative return) and expected current draw. As a guide, 8B&S (7.9mm²) is suitable for 60A continuous loads over short to moderate distances in 12V systems. Always refer to JASO D609 derating tables when bundling multiple cables or operating in ambient temperatures above 30°C. Professional installation by a qualified auto electrician is recommended for high-current circuits.

Reasonably adequate room divider
Size: 4 Panel-88'', Color: Beige
I'm reviewing this as I assemble it. Couple things: 1. I didn't expect as much assembly. I've ordered dividers before and they more-or-less came as one unit. Sometimes the panels needed screwing together. These require complete assembly and come largely as three rods: two make up vertical columns and snap together. Another one (called part "C") makes the horizontal columns and you have two of these per panel (one attaches to part "A" and the other part "B"). These parts are metal with a plastic shim. Using the wood screws to attach to part "C" is a real pain in the neck. There's not much holding the panel in place so it's a little tricky. One tactic I've found while I'm assembling that works for the initial connections from parts A and B to their respective "C" rods is to hold the screw in place with a screw driver and then rotating the rod around the screw. This will do a number on your hands if you aren't wearing gloves. This obviously doesn't work when completing the connection. Using a driller driver on this is really near impossible because there isn't anything you can use to secure it in place. You can use it on the first panel, but as it gets longer, it becomes increasingly difficult and because it isn't wood, it's really tight. I considered drilling larger pilot holes but since there are only 4x4=16 screws I need to screw in, I just decided to use my screw driver to complete it. 2. Also related to assembly. When completing the panels (attaching parts "A" and "B" to parts "C" that have the cloth cover on it), you have to be careful that when you tighten that side that it isn't loosening the other side. Because the pilot holes are so tight, you can end up rotating the rod, which rotates it in the same direction as looser on the original side. Having someone hold the "C" rod in place while you screw it in is probably the easiest approach. I didn't have a 2nd person, so I just had to keep flipping back and forth and tightening both sides as I screwed it in. Not the worlds biggest deal, but annoying nonetheless. 3. The way the instructions are written, they seem to suggest building this thing progressively; that is, you do panel 1, then 2, connect them together, then do 3 and connect it, etc. I took a different route that I suspect saved me quite a bit of trouble, and I assembled all four panels first and THEN connected everything together. 4. For the love of God make sure you check that the plastic tip is on the same side for every panel. Otherwise, you have to take one side apart again and reverse it. On the bright side, if this happens, you've essentially bored out the pilot holes to be the correct size... which is having me question if I shouldn't have just bored them out to the appropriate width in the first place. 5. Attaching all of the panels together is also an enormous pain in the ass unless you happen to have an 88" long elevated surface. Attaching the legs either requires you to elevate one side, which will invariably twist the inexplicably cheap material in the bottom connectors... or you can attach them sideways... or you can put this thing upright, having two people hold the panels in place while you use the allen wrench to tighten the bolts on the underside. None of those are particularly great options. NOW on to the utility itself. 1. The panels do let some light through (I didn't believe their advertising, and that was one of the reasons that I bought beige, is that I wanted it to not be too dark). They aren't transparent though, so it isn't that far off from their description. They functionally work great, and keep the mess of wires hidden and when I'm sitting at my desk, actually reflect quite a bit of light into my office. Great! 2. My wife has described these as "the most hideous piece of furniture ever conceived of by man." So it does not have spouse approval factor. Granted, she will seldom be in my office area, so that isn't the end of the world. 3. These are really hard to align in a way that doesn't look a little tacky. There are some plastic connectors but they don't do a bang up job of keeping these in place. Each panel is slightly tilted and it's... quite obvious. I may at some point make my own improvements to these to help make them more level. It's not a particularly expensive product so I wasn't expecting much so it's fine and I'm not going to ding them on the rating because of it. All said, would I buy this product again? Probably not. It's assembly was ~90 minutes which is about 75 minutes longer than I was anticipating spending on this (not including the 5 minute writeup that I'm doing here). But am I going to return it? Also no, if for no other reason I'd be just as annoyed taking it apart and putting it in the original box to return it.

Love it it was perfect for what I needed it for. Good quality!
Size: 4 Panel, Color: Black
It like a very dark chocolate brown/black. What I liked most about it is that you just pull it out of the box take the long plastic film off of it and it's ready to go. It has protective feet on the bottom. It's very attractive and it was so easy. It's so nice when you have a product you don't have to assemble.

Shipped quickly and as described
It was what I expected as functionality, lightweight and easy to move about. I plan to use it in my enclosed patio to obscure weight bench and wts. My only complaint is that the bamboo cover on one edge is not secure. But I will probably use a magic marker to cover the natural back that is showing. I don’t have time to return it as my event is coming soon.

Good product, needs double hinges for versatility.
Size: 6 Panel, Color: Brown
Blocks out all the light, looks good, good color. Only con is that it is not double hinged so it is hard to position the extra panels because I bout 6 panels instead of the 4 I usually get. Good deal, very decent price with the free delivery. Very clean packaging, came in great shape, no smell or odor from the factory.
