Electra-Cables | 2.5mm Twin & Earth Flat Cable PVC/PVC | White Sheath
The Electra-Cables 25TE20 is a 2.5mm twin and earth flat cable rated 450/750V, supplied in a 20-metre cut length. The cable carries plain annealed copper conductors under PVC insulation with a white PVC sheath, designed for general wiring in domestic, commercial, and industrial installations where not subject to mechanical damage.
Electricians specify 2.5mm twin and earth for standard power circuits in residential renovation and new-build work. The flat profile suits enclosed runs, conduit burial, and direct underground duct installation. Twenty-metre cuts strike the balance between job practicality and stock efficiency, avoiding excess cable waste on smaller rewires and kitchen upgrades. Sparkies appreciate the flexibility of shorter lengths alongside the 10m and 100m options, making it easy to stock one cable size and cut to the job demand.
The 25TE20 fits straightforwardly into standard cable clips and conduit systems. Conductor size sits at the sweet spot for typical 16A or 20A subcircuit protection in domestic switchboards. Easy-tear sheath makes termination and installation faster on site, with no specialist tools required. The cable meets Australian Standard AS/NZS 1125 for conductor purity and construction, so testing and compliance are already built in.
Features
- 2.5mm conductor cross-section — carries 16A to 20A circuit protection in domestic and light commercial subcircuits, sized for kitchen, bathroom, and general power distribution.
- Twin and earth configuration — active and neutral conductors plus separate earth conductor; complies with AS/NZS 3000 installation wiring rules.
- 450/750V voltage rating — suitable for household mains supply and industrial applications up to 750V operation.
- Plain annealed copper conductors — conforms to AS/NZS 1125; handles repeated bending and flexing during cable runs without embrittlement.
- PVC V90 insulation — fire-rated insulation provides flame resistance, meeting Australian electrical safety standards.
- White easy-tear sheath — 3V-90 rating; three-layer construction (3) allows rapid sheath removal for termination without knife damage to inner conductors.
- 20-metre supply length — cuts waste on small jobs; reduces on-site surplus and returns while providing sufficient cable for typical domestic branch circuits.
- Flat cable profile — easier routing through cable trunking, conduit runs, and narrow enclosed spaces than circular alternatives.
- Direct burial rated — sheath and insulation tolerant of soil contact in underground duct and cable duct burial; does not require additional protection layer.
- Electra-Cables brand — Australian-sold cable range from Prysmian, Apec, Olex, or Advance (brand may vary by buy price; Sparky Direct secures best pricing).
Where to use
- Kitchen and bathroom power circuits — the 25TE20 is the standard cable for appliance circuits, bench-top outlets, and hot-water switch runs in domestic rewires and renovations.
- Lounge, bedroom, and general-purpose circuits — power distribution for lights, fans, and general-use GPOs on 16A or 20A protection.
- New house wiring and extensions — bulk of subcircuit distribution in new builds; cut to length as branch circuits from the main switchboard.
- Conduit and trunking runs — flat profile fits conduit bends and surface-mounted cable trunking; flat cables occupy less duct space than circular.
- Underground and buried installation — cable duct, direct soil burial, and underground duct runs for outdoor power distribution and site supply.
- Industrial wiring and sheds — supply cable for workshop power distribution, machinery circuits, and industrial lighting on standard 16A or 20A subcircuits.
The 25TE20 is not suitable for continuous outdoor exposure (weatherproof conduit or conduit protection required), submersion in water, or areas subject to mechanical impact or abrasion. The cable is for fixed installation only and should not be used as a temporary extension or flexible power lead.
