The SRF3025V-100WHE is a 2.5mm² twin and earth flat TPS cable supplied on a 100 metre drum, with plain annealed copper conductors, PVC V90 insulation and a 3V-90 easy-tear white sheath. It is rated to 450/750V, certified to AS/NZS 5000.1 with plain annealed copper conductors to AS/NZS 1125, and is the default 2.5mm cable run for general power point circuits in Australian homes.
The SRF3025V-100WHE is the cable most often pulled off a sparky's truck for 20A general power circuits — kitchens, laundries, GPO runs, sub-circuits feeding a few points. It is fixed wiring intended for installation by a licensed electrician, run unenclosed, in conduit, buried direct, or in underground ducts in any installation not subject to mechanical damage. Stock is typically Electra Cables; brand may rotate to Prysmian, Apec, Advance Cables, or Olex depending on supply, all AS/NZS compliant.
For new builds, rewires, and bigger jobs, the SRF3025V-100WHE is the workhorse drum to spec. It runs alongside the 7-050-2ERB 1.5mm twin and earth for lighting circuits and the 7-104-2ERB 6mm for hot water and dedicated appliance loads. For installs where the cable will sit against polystyrene insulation or polyurethane foam, switch to the non-migratory purple SRF3025VHT-100P instead — the standard PVC plasticiser will leach over time in contact with those materials.
For installs where the cable will sit in contact with polystyrene or polyurethane foam — common in modern wall and ceiling insulation systems — use the non-migratory purple SRF3025VHT-100P instead. Standard PVC plasticiser leaches over time when it touches these materials, which can degrade the cable insulation; the non-migratory compound is formulated to resist that reaction.

The SRF3025V-100WHE is manufactured to AS/NZS 5000.1 with plain annealed copper conductors to AS/NZS 1125, rated 450/750V. It is suitable for fixed wiring in domestic, commercial, and industrial installations not subject to mechanical damage, when installed by a licensed electrician under AS/NZS 3000.
Fixed wiring in Australia must be installed by a licensed electrician. This applies to all twin and earth cable feeding power points, lighting, or any permanently connected load. The SRF3025V-100WHE is sold as wholesale stock for the trade and for owner-builders engaging a licensed installer.
2.5mm² twin and earth is the standard cable for 20A general power point circuits in Australian residential and light commercial work. It is also used on long lighting runs where 1.5mm would exceed the 5% voltage drop limit set out in AS/NZS 3000. Cable size must always be confirmed by calculation against the protective device and run length.
The 3V-90 easy-tear sheath is designed to split cleanly along the length of the cable when stripped, separating the active, neutral, and earth conductors without nicking the insulation. It saves time at rough-in and at terminations, particularly when landing into GPOs, switchboards, and junction boxes.
This cable is rated for direct burial or installation in underground ducts in locations not subject to mechanical damage. For runs under driveways, paths, or anywhere mechanical protection is needed, use it inside orange heavy-duty conduit. For longer underground feeds, orange circular cable in the same conductor size is more common.
Stock is typically supplied as Electra Cables. Depending on availability, the same SKU may ship as Prysmian, Apec, Advance Cables, or Olex — all manufactured to AS/NZS 5000.1 and carrying the RCM mark. If a specific brand is required for a job or specification, contact Sparky Direct before ordering to confirm current stock.
Avoid runs where the cable will sit in direct contact with polystyrene or polyurethane foam insulation. Standard PVC plasticiser migrates into those materials over time and can degrade the cable insulation. Use the non-migratory purple SRF3025VHT-100P in those locations. Also avoid any installation subject to mechanical damage unless the cable is run inside conduit or duct.
For lighting circuits, 7-050-2ERB is the 1.5mm twin and earth 100 metre drum. For dedicated appliance loads such as hot water, air conditioning, and induction cooktops, step up to 7-104-2ERB 6mm twin and earth. 1mm and 4mm sizes are also available across the same Electra range for matching load and protective device requirements.
