The Electra-Cables 7-085-2ERB is a 4mm two-core-plus-earth cable rated 450/750V AC, designed for general fixed wiring in domestic, commercial, and industrial installations. The 7-085-2ERB carries 4.0mm² red and black conductors (active and neutral) plus a 2.5mm² green/yellow earth conductor. It complies with AS/NZS 5000.2 and AS/NZS 3808.

Installation work often requires cable that balances conductor gauge with practical handling on site. A 4mm two-core-plus-earth cable suits circuits drawing higher loads—stovetops, instantaneous hot water, air conditioning sub-boards, and workshop power distribution—where a 2.5mm² cable would be undersized. The easy-peel white PVC sheath strips faster than standard sheath, reducing on-site labour. Bulk 100m drums suit job purchasing and repetitive wiring runs.

Electricians value the Electra-Cables range for consistency across domestic and commercial jobs: a single cable type works across multiple circuits when the load calculation supports 4mm conductors. The flat profile fits wall cavities and floor voids more readily than round cable, simplifying concealed runs. Bulk pricing on the 100m drum supports solid margins when supplying site power or upgrading switchboard sub-circuits. Stock rotation is straightforward since 4mm T&E cable is a standard line item across most job types.

Features

• 4.0mm² active and neutral, 2.5mm² earth — seven-strand annealed copper conductors meet AS/NZS 1125, rated for circuits with higher demand such as cooktops, hot water units, and sub-board feeds.
• Voltage rating 450/750V AC — suitable for general fixed wiring in domestic, commercial, and light industrial circuits at standard mains voltage.
• Operating temperature 90°C — rated for continuous operation in enclosed conduit and concealed runs without derating under typical domestic and commercial installations.
• Easy-peel white PVC sheath — tear-away sheath design allows faster cable preparation on-site and reduces hand fatigue compared to standard sheath, particularly on bulk 100m runs.
• Flat profile 14.1mm × 6.5mm — compact cross-section routes through wall cavities, under floorboards, and in conduit runs with minimal disruption to the building fabric.
• Minimum bend radius 30mm — allows tight routing through standard corners and junction boxes without overstressing the insulation.
• 100m drum length — bulk supply suits job wiring, repetitive circuits, and site distribution networks where off-the-reel installation reduces connector count and labour time.
• Colour-coded conductors — red (active), black (neutral), and green/yellow (earth) enable rapid identification during installation and compliance with the wiring rules.
• Not weather-protected — for use only in indoor, enclosed, or underground ducted applications; not suitable for exposed external walls, damp unenclosed areas, or direct burial without conduit protection.
• Complies with AS/NZS 5000.2, AS/NZS 1125, and AS/NZS 3808 — approved for use in Australian domestic and commercial installations under the National Electricity Rules.

Where to use

• Kitchen and laundry circuits — the 4mm conductors provide the gauge needed for cooktops, electric water heating, and combination appliances that exceed 2.5mm² capacity.
• Air conditioning sub-board feeds — 4mm T&E cable is the standard choice for outdoor unit supply circuits and internal sub-board distribution in domestic and commercial cooling installations.
• Workshop and garage power — supplies high-demand tools, compressors, and three-phase outlets that require 4mm conductors to stay within voltage drop limits over longer runs.
• Underfloor concealed runs — the flat profile and easy-peel sheath make rapid installation in floor voids and wall cavities practical on renovation and new-build sites.
• Not suitable for wet areas or external exposure — only use indoors or in underground conduit; do not expose to direct weather, high moisture, or UV light without additional protection.
