This Tycab Black/Red 4mm² Twin Core 30m Twin Sheath cable gives you a tidy way to run both positive and negative on 12V gear up to 22A. The 30 metre spool works well for full‑length dual battery feeds on utes and camper trailers without needing extra joins. The flexible 23 x 0.32mm copper stranding bends around canopies, drawers and chassis rails so you can route the setup where it actually fits. You get clearly marked black and red cores inside a single black sheath, so tracing polarity across the full 30m run is straightforward when fault‑finding. The PVC insulation is rated to about 90°C, which handles hot interiors and summer temps across most Aussie regions. The 4mm² conductor size and 22 amp rating suit fridges, lighting looms and smaller loads, making this a smart buy for general touring wiring without over‑speccing your cable.

Q: Can this 4mm twin core cable run a 12V fridge and lights on the same circuit?

Yes, if the combined current stays within 22A. The cable is rated to carry up to 22 amps along its length, so a typical compressor fridge at around 5–10A plus a few LED lights usually sits under that. Always add up the draw of every accessory on the run. Keep the total comfortably below 22A for continuous use.

Q: Is the 30m length supplied as one continuous spool?

Yes, this cable is supplied as a single 30m spooled length. A continuous run helps reduce joins, which in turn reduces potential voltage drop and failure points. You can cut the spool into shorter lengths to suit different parts of your setup. Always terminate each cut with the correct lugs or connectors for the gear you are wiring.

Q: Can this cable be used in engine bay areas?

It can be used around engine bay edges within its 90°C rating. The PVC insulation and sheath handle typical ambient heat near but not directly on high‑temperature components. Route the cable away from exhaust manifolds and other extreme hot spots. Securing it with suitable clips or conduit will help protect it from vibration and abrasion.

Q: Is this cable suitable for 12V and 24V systems?

Yes, the 4mm² twin core design works on both 12V and 24V DC setups within the 22A rating. Higher‑voltage systems draw less current for the same power, which can help with voltage drop over longer runs. Always size your cable based on current draw and length, not just the voltage. If in doubt, consult an auto electrician for final checks.
