Evincab 2.5mm Black (per metre): Conductor Construction
The conductor is manufactured from plain annealed copper, chosen for its excellent electrical conductivity and ductility. The stranded construction consists of multiple fine copper wires twisted together, typically 7 strands of 0.67mm diameter for Class 2 stranded conductors.
This stranding offers several advantages:
Flexibility: Easier to bend and route through conduit and trunking compared to solid conductors
Vibration Resistance: Less prone to work-hardening and breaking in applications subject to movement
Termination: Provides better contact area in screw terminals
Handling: Easier to strip and prepare for connection
Quality: Made with high-purity copper conductor for optimal performance
Evincab 2.5mm Black (per metre): PVC Insulation
The black PVC insulation serves multiple critical functions:
Electrical Insulation: Provides excellent dielectric strength, preventing electrical leakage and ensuring safe containment of the live conductor.
Mechanical Protection: Protects the copper conductor from abrasion, impact, and damage during installation and service.
Colour Identification: The black insulation allows for specific identification in circuits where black is designated for a particular function, such as phase identification or control wiring.
Environmental Resistance: PVC offers good resistance to moisture, chemicals, and is suitable for use in wet or dry locations .
Temperature Rating: Rated for continuous operation up to 70°C, suitable for normal operating conditions in buildings.
Flame Retardant: PVC insulation is flame retardant, meeting safety standards for electrical installations.
Evincab 2.5mm Black (per metre): Current Ratings
The current-carrying capacity of 2.5mm² cable depends on installation method:
| Installation Method | Typical Current Rating |
|---|---|
| In conduit (clipped) | 24-25 Amps |
| In trunking | 25-26 Amps |
| In free air | 27-30 Amps |
| In thermal insulation | Reduced rating – consult regulations |
These ratings are typical and may vary based on ambient temperature, grouping with other cables, and specific installation conditions. Reference should be made to the current edition of wiring regulations for final sizing.
Evincab 2.5mm Black (per metre): Applications

Trunking Systems: Suitable for installation in PVC or metal trunking for distribution wiring in commercial buildings.
Control Panels: Used for internal wiring of control panels, distribution boards, and electrical enclosures.
Switch Wiring: Provides connections between switches, outlets, and accessories throughout the installation.
Industrial Applications: Suitable for general purpose wiring in light industrial environments .
Building Wiring: Used as building wiring for power, lighting and switch control wire .
Evincab 2.5mm Black (per metre): Voltage Rating
Depending on the manufacturing standard, this cable is typically rated at either 450/750V or 600/1000V . This makes it suitable for standard single-phase and three-phase installations, covering all normal domestic and commercial applications.
Evincab 2.5mm Black (per metre): Why Buy Per Metre?
Purchasing this cable by the metre offers several practical advantages:
Cost-Effective: Buy exactly what you need for your specific project. No waste and no unused cable left coiled.
Project-Specific: Perfect for small jobs like wiring a single socket or extending a power circuit. Ordering per metre gives you complete control over quantities.
No Storage Issues: Avoid storing bulky coils of cable. Order precisely for your current requirements.
Flexible Quantities: Need 3 metres for one job and 10 metres for another? Order exactly per metre.
Evincab 2.5mm Black (per metre): Installation Considerations
Conduit and Trunking: This cable is designed for installation within conduit, trunking, or other approved containment systems that provide mechanical protection. It is suitable for use in wet or dry locations .
Bending Radius: The minimum bending radius should be observed to prevent damage to the conductor or insulation. Typically 3 times the cable diameter.
Stripping: Use appropriate cable stripping tools to remove insulation without nicking or damaging the copper conductor strands.
Termination: Ensure conductors are correctly terminated in suitable terminals, with no stray strands exposed. The correct torque should be applied for the terminal type.
Derating: When multiple cables are bunched together, derating factors apply to the current-carrying capacity. Consult wiring regulations for guidance.
Colour Identification: While black is used for this cable, ensure correct identification and labelling as required by regulations for the specific circuit function.
Evincab 2.5mm Black (per metre): Important Notes
Continuous Length: When you order multiple metres, you will receive one continuous length of cable, not multiple separate pieces. For example, ordering 5 metres supplies a single 5-metre length.
Cut to Order: Each length is cut from a full reel specifically for your order per metre. This may add a small processing time to dispatch.
Returns: Due to hygiene and safety reasons, cut cable cannot be returned unless faulty. Please measure your requirements carefully before ordering per metre.
Evincab 2.5mm Black (per metre): Quality and Compliance
This cable is manufactured to meet rigorous international standards:
BS 6004: British Standard for PVC-insulated cables for electric power and lighting
UL83: American standard for thermoplastic-insulated wires
CE Marking: Indicates compliance with relevant European directives
RoHS Compliance: Free from hazardous substances
Flame Retardant: Meets relevant standards for fire performance
Evincab 2.5mm Black (per metre): Measuring Your Needs
To determine how much cable you require:
Power Circuits: Measure from the distribution board to socket positions, allowing for routing around obstacles.
Control Wiring: Measure panel layouts and add extra for neat routing and termination.
Extension Wiring: Measure the distance from existing points to new locations.
Always add extra for connections at each end—typically 100-150mm per termination to allow for comfortable working.
Allow for routing around corners, through walls, and along cable trays.
When installed correctly within appropriate containment and in accordance with current wiring regulations, Evincab 2.5mm Black, available per metre, provides a safe, reliable, and versatile solution for power circuits and fixed wiring in residential, commercial, and industrial applications.
