Tycab Grey 4mm Single Core cable runs a 4mm² copper core that comfortably carries up to 15A in typical 12V setups, so you can wire lights or compressors without oversizing the loom. With a 90°C temperature rating, it handles the warm air around engine bays and canopy chargers when you get out there across long highway stretches or corrugated tracks. Inside the grey sheath you have 23 copper strands at 0.32mm each, which keeps the cable flexible enough to route through tight corners in utes and camper trailers. The single-core layout in grey works well as a negative or accessory feed when you want colour separation in your kit. Sold per metre, this is a smart buy when you want enough cable for the job without piles of leftovers sitting in the shed.

Q: Can I buy this cable in one continuous length?

Yes, the Tycab Grey 4mm Single Core is sold per metre as a continuous length. If you order 5 units you receive one 5m length, not separate 1m pieces. This makes it easier to run full circuits without extra joins. It also helps keep voltage drop under control on longer 12V runs.

Q: Is 4mm single core suitable for a 15A fridge circuit?

Yes, this 4mm single core cable is rated to 15A. For a fridge that draws up to that current, this size is appropriate for short to moderate cable runs. Keeping joins to a minimum will help maintain voltage at the fridge end. Always match it with correctly rated fuses and plugs.

Q: What colour is the insulation and how does that help with wiring?

The insulation on this cable is grey. Using a consistent grey for negative or accessory lines makes it easier to trace circuits later. When paired with a contrasting positive colour, you can quickly see polarity at terminals. That saves time when fault-finding or adding extra gear.

Q: How flexible is this cable for routing through vehicles?

The cable uses 23 copper strands at 0.32mm each, which keeps it quite flexible. This helps when feeding it through body panels or conduit in tight spaces. The stranded construction also copes better with vibration than a solid conductor. It is well suited to touring and trailer setups that see plenty of movement.
