House Wire (Single-Core PVC Cable) – 1.5mm² to 16mm², per Metre or 100m Roll

House wire (single-core PVC cable)

House wire is single-core, PVC-insulated copper cable. It is pulled through conduit to wire lights, plugs, geysers and stoves, and to run earth conductors. We cut it to length per metre, and the most-used sizes also come as full 100m rolls, which work out cheaper per metre.

Which size for which circuit

• 1.5mm² – lighting circuits.
• 2.5mm² – plug (socket) circuits.
• 4mm² – 6mm² – geysers, stoves and longer or heavier circuits.
• 10mm² – 16mm² – supply to the DB board, sub-boards and main earth.

This is a rough guide. The right size also depends on the breaker, the load and the length of the run, so always have a qualified electrician confirm it.

Colours

Red (or brown) for live, black (or blue) for neutral, and green/yellow only ever for earth.
