The Electra 6mm building wire is a single-core, 0.6/1 kV rated earth conductor for switchboard and control panel wiring. The 6mm cable carries 38 amps and complies with AS/NZS 1125, AS/NZS 5000.1, and AS/NZS 3808 standards. The 6mm cable is manufactured from plain annealed copper with PVC V90 insulation rated to 90 degrees Celsius, making it suitable for wiring within enclosed apparatus and switchboard applications.
Switchboard and control panel wiring often demands a separate earth conductor rated to match the active and neutral conductors. Electricians on domestic rewires, commercial fit-outs, and industrial panel builds specify building wire for its reliability in enclosed applications where the cable is not accessible without tools. The Electra 6mm is a workhorse earth conductor, stocked in 100-metre reels for jobs that call for bulk length. Larger switchboards and multi-dwelling installations often require dedicated earth runs where a single-core cable outperforms sheathed multicores in tight conduit runs.
Licensed electricians choose the Electra 6mm for panel work because it delivers certified performance at a competitive price, fits standard 100-metre reel lengths for easier inventory management, and pairs seamlessly with other Electra building wire sizes (4mm, 10mm, 16mm) for consistent specifications across a jobsite. The green and yellow colour coding is mandated by AS/NZS 3000 for all earth conductors, reducing the risk of mis-termination on busy switch-rooms. The PVC sheath resists oil and coolant exposure common in industrial control panels, and the 25mm minimum bend radius accommodates tightly wound conduit.
The Electra 6mm building wire is not suitable for flex applications, high-vibration or mobile installations, or locations requiring halogen-free insulation. It is an enclosed-wiring product only and should not be used for direct burial, external exposure, or submersion in water.

The Electra 6mm building wire is rated for 0.6/1 kV and carries 38 amps. It complies with AS/NZS 1125, AS/NZS 5000.1, and AS/NZS 3808 standards and is suitable for switchboard and control panel wiring in domestic, commercial, and industrial applications.
Yes. The 6mm cable is sized for earth distribution in domestic switchboards and sub-boards up to 50 amp main protection. Licensed electricians specify it as the standard earth conductor for residential rewires and commercial panel installations.
The conductor is plain annealed copper, which maximises conductivity and provides the flexibility needed for routing through conduit and cable trays without brittle cracking.
PVC V90 indicates the insulation material (polyvinyl chloride) is rated for normal operating temperatures up to 90 degrees Celsius. This is standard for indoor enclosed wiring in switchboards and control panels, though the cable is also oil and coolant resistant.
The Electra 6mm is supplied as a 100-metre continuous length on a reel, which covers most domestic switchboard earth runs and many commercial panel installations without requiring a mid-run splice.
No, the 6mm Electra building wire is designed for enclosed wiring only (switchboards, control panels, and apparatus) and is not rated for direct burial, outdoor exposure, or submersion. For external earth applications, a marine-grade or UV-resistant cable is required.
