This Tycab Red/Black 4mm Trace Single Core cable handles circuits up to 15 amps on typical 12V camping or trailer setups. The 4mm² size works well for fridges rated under 10A or lighting bars drawing under 15A on runs of a few metres. The red sheath with a black trace makes polarity checks simple when you are under the tray with a head torch. Inside the sheath you get 23 strands of 0.32mm copper for good flexibility around tight 50mm bends. The PVC insulation is rated to 90°C so it holds up inside canopies and along chassis rails in Aussie summer heat. The cable is sold per metre so you only pay for the length you actually pull through the rig. That keeps the setup a smart buy when you are rewiring more than one circuit.

Q: Can this 4mm cable be used for a 12V fridge circuit?

Yes, within its 15A rating and sensible run lengths. Most portable 12V fridges draw well under 10A so this 4mm cable has headroom for startup currents. Keep the run as short as practical to limit voltage drop. Match it with an appropriate fuse sized to protect both the cable and your fridge wiring.

Q: Is the red/black trace suitable for identifying positive wiring only?

Yes, this red cable with a black trace is typically used as the positive conductor. The colour and trace make it simple to distinguish from plain black negative returns in a loom. Keeping a consistent colour code across the vehicle makes fault finding quicker. Always stick to your chosen convention when adding new circuits.

Q: What type of terminals should I use with this cable?

Use terminals correctly sized for 4mm² automotive cable. A snug barrel match gives full contact on the 23 copper strands and maintains the 15A rating. Always crimp with a proper ratchet crimper rather than pliers. Add heat‑shrink where needed to protect the joint from moisture and abrasion.

Q: Can this cable run through engine bay areas?

Yes, within normal 90°C temperature limits and with mechanical protection where it crosses sharp edges. The PVC insulation handles typical under‑bonnet warmth in Australian conditions. Run it inside split conduit where it might rub on metal. Secure it with quality cable ties so it does not move against hot or moving components.
