OW power cable 3 x 2.5 mm² 300/500V (OW3X2,5) is a flexible single-core conductor assembly with three insulated cores and a protective sheath, intended for general electrical installation and internal wiring. It is rated for 300/500V and provides a commonly used conductor cross-section of 2.5 mm² per core, suitable for many domestic and light commercial circuits where three-core cable is required for fixed installation.
Advantages
The OW 3 x 2.5 mm² cable offers reliable current carrying capacity for lighting, socket circuits and small power circuits while maintaining flexibility that eases routing in conduits and trunking. Its construction provides consistent conductor size and insulation thickness for predictable electrical performance and safe fixed installation according to standard wiring practices.
Suitable for
- Lighting circuits and switched lighting loops
- Socket outlet circuits in small flats and rooms
- Fixed internal wiring in domestic and light commercial installations
- Connection of small motors, appliances and distribution between junction boxes
When it may not be suitable
This cable is designed for fixed internal installations and is not intended for permanent outdoor burial or direct exposure to sunlight without appropriate protection. It may not be suitable where higher voltage ratings, larger conductor cross-sections or specialized cables with enhanced mechanical protection, fire-resistant or low-smoke halogen-free properties are required.
Key specifications
- Number of cores: 3
- Conductor cross-section: 2.5 mm² per core
- Voltage rating: 300/500 V
- Conductor type: single-core flexible conductor per core
- Application: fixed internal electrical installation
How to use
Install the cable as part of fixed wiring following national and local electrical codes. Strip outer sheath and individual core insulation to appropriate lengths, terminate cores into connectors or device terminals with correct torque and use suitable cable clamps or glands to secure the cable. Ensure correct colour identification and earthing practices are observed. Use protective conduit or trunking where required by installation rules and avoid sharp bends that exceed the cable's minimum bending radius.
What to consider before purchase
- Confirm that 2.5 mm² conductor size and three-core configuration match circuit load and breaker ratings.
- Verify the 300/500V voltage rating is appropriate for your supply and installation requirements.
- Check whether additional mechanical protection, fire performance or outdoor-rated cable is needed for your location.
Usage recommendations
Use this OW 3X2,5 cable for indoor fixed wiring runs where standard 2.5 mm² conductors are specified; pair it with correctly rated protective devices and follow installation regulations to achieve safe, long-lasting circuits.
