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.
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.

(25TE20)
The 25TE20 is rated for 16A or 20A circuit breaker or RCD protection. A single-pole 16A MCB suits general-purpose circuits; a 20A MCB is used for higher-load runs. RCD protection is mandatory on all circuits in bathrooms, kitchens, and outdoor areas per AS/NZS 3000. Always confirm the correct breaker rating with your Licensed Electrician before installation.
The 25TE20 is rated for direct soil burial in cable duct or underground duct; no additional conduit wrapping is required. For exposed outdoor runs above ground, conduit protection is mandatory. Avoid bare soil contact in high-traffic areas—use duct protection where foot or machinery traffic is possible.
The 25TE20 is an indoor cable and is not weatherproof. For external installations, use weatherproof cable or run the 25TE20 inside weatherproof conduit. Do not expose the sheath to direct sunlight, rain, or damp environments without conduit protection.
All three use the same cable; the difference is supply length only. The 20m cut suits typical domestic branch circuits and small jobs without excess waste. The 10m is for shorter runs and site flexibility. The 100m roll is for bulk projects, new-build housing, and commercial installations where full-length runs are practical.
