10m 4mm Red Tinned Marine Wire

A 10 metre cut of 4 mm red tinned marine wire. Single core, no outer sheath. Industry size is 4 mm. Conductor area is 1.85 mm², not 4 mm². Use it as the positive on a 12 V or 24 V circuit.

Need both colours: 10 m red and 10 m black, 20 m pack. The matching negative is 10 m black 4 mm tinned marine wire. For red and black in one jacket, use 10 m tinned marine twin cable, 4 mm.

4 mm tinned marine wire, red

This is the red single core used for a positive feed on a boat. Tinned copper, V90 PVC, cut to 10 metres.

• Positive to a manual bilge pump, through a fused switch.
• Positive feed to lights, instruments and accessories.
• Extending an existing red marine wire.

It is not twin sheath. Twin sheath is red and black inside one white jacket, sold as the 10 m twin cable. It is not 3 core. An automatic bilge pump needs 10 m 3 core bilge pump wire. Do not use this wire on 240 V, shore power or inverter output.

Specifications

Standards

• AS/NZS 1125. Tinned copper conductor.
• AS/NZS 3808. V90 PVC insulation.
• RoHS. Insulation compound is RoHS compliant.

Extra-low voltage, for pleasure craft. Not for mains connection. AS/NZS 3000 is the wiring rules for the installation, not a standard this wire is certified to.

4 mm is not 4 mm²

On Australian auto and marine cable, 4 mm is the trade name. The copper is 1.85 mm², 26 strands of 0.30 mm. A 4 mm² building cable is a different product. Blue crimp terminals are the usual match.

Questions

Is this the same as 4 mm twin marine cable?

No. This is one red conductor. Twin cable has red and black in one sheath. That search is the 10 m tinned marine twin cable.

Do I need black as well?

Yes, for a complete circuit. Buy the black 10 m cut, or the 20 m red and black pack.

Is the copper tinned?

Yes. Tinned copper to AS/NZS 1125. The tin coat is what separates this from plain auto wire in salt air.
