Electra-Cables 7-104-2ERB | 6mm Twin & Earth Flat Cable PVC/PVC | 100 Metre Drum
The Electra-Cables 6mm Twin & Earth Flat Cable is a general-purpose fixed wiring cable rated for domestic, commercial, and industrial installations under AS/NZS 3000 and AS/NZS 5000.1. The 6mm² active and neutral conductors deliver higher current capacity than smaller gauges, while the 2.5mm² earth wire provides compliant fault protection under AS/NZS 3000. The 100-metre drum suits large site runs, new-build sub-mains, and major rewires where bulk cable saves on joins and installation time.
Electricians specify 6mm twin and earth for sub-main circuits, workshop power distribution, and high-demand renovation runs where smaller gauges would require derating. The easy-tear white PVC sheath strips cleanly in the field, cutting labour time on wire preparation. Bulk drums reduce per-metre cost compared to cut lengths, a key margin driver on larger jobs. Stock rotation is straightforward: the same drum suits any installer or contractor stocking the full gauge range.
Licensed electricians favour this cable for load-bearing circuits because the 6mm² conductor cross-section delivers significantly higher current capacity than 2.5mm or 4mm cable, reducing voltage drop on longer runs and enabling heavier appliance loads without circuit derating. The easy-peel sheath saves prep time on the tools, and the 100-metre drum format keeps material cost competitive for large-scale work. The cable is suitable for unenclosed runs, conduit, underground ducts, and burial on qualified sites where mechanical protection is assured.
Features
- 6.0mm² active and neutral conductors — higher current capacity than 2.5mm or 4mm gauges, reducing voltage drop on longer sub-main and distribution runs.
- 2.5mm² earth wire — sized to provide compliant fault protection under AS/NZS 3000 without over-specifying.
- Easy-tear white PVC sheath — strips cleanly in the field with a fingernail or flat edge, cutting wire-prep time compared to stiff jackets.
- PVC/PVC insulation, 75°C rated — standard thermal rating for domestic and commercial fixed wiring, meeting AS/NZS 5000.1 construction requirements.
- 100-metre drum format — bulk supply reduces per-metre cost and minimises joins on large site runs, a key margin item on commercial projects.
- AS/NZS 3000 and AS/NZS 5000.1 compliant — genuine RCM-marked cable meeting all Australian wiring standards without caveat.
- Solid copper conductors, annealed copper — high conductivity and ductility, standard on quality Australian fixed-wiring cable.
- General-purpose wiring application — suitable for unenclosed runs, closed-in conduit, buried direct in non-hazardous sites, and underground ducts where mechanical damage is not a risk.
- Colour-coded insulation — red for active, black for neutral, green/yellow for earth, eliminating field guesswork on termination.
- Not rated for direct UV exposure — standard PVC brittle under prolonged sunlight; external runs require conduit, UV-resistant alternatives, or shading.
Where to use
- Sub-main circuits — the 6mm Twin & Earth distributes high-load power from the switchboard to sub-boards, garages, sheds, and annex switchboards in new builds, major renovations, and extensions.
- High-load circuit protection — cooktops, stovetops, split-system air conditioning, and three-phase motor circuits running on 32A or 40A protection demand the 6mm gauge to stay within derating thresholds.
- Workshop and garage power — industrial machinery, welders, compressors, and multi-tool setups on site run from 6mm distribution without voltage drop or thermal stress.
- Long-run domestic circuits — runs exceeding 20 metres (e.g. pool house, garden studio, detached garage) use 6mm to avoid the voltage loss associated with finer gauges over distance.
- Commercial office fit-outs — large open-plan power distribution backbones use 6mm as a cost-effective bulk supply before breaking into smaller circuits at local distribution boxes.
- Underbuild ducts and buried runs — sub-floor conduit and underground trunk routes to remote buildings use the 6mm drum as the backbone, with smaller circuits branching from local junction boxes.
- Industrial and agricultural applications — factories, farms, and workshop electrification where the 6mm gauge is matched to larger breaker ratings (32A, 40A, 50A) and heavy machinery loads.
The 6mm Twin & Earth is not suitable for external runs exposed to direct sunlight, overhead aerial installation, or areas subject to mechanical abuse. Do not bury in direct earth without conduit protection, and do not use for mobile temporary power (extension leads) — that application calls for flexible cable with appropriate plugtops and safety switch protection.
