Product Information
Full details
This guide is for electricians and installers working on projects requiring fire safety compliance. The Time 6491B cable provides a key benefit of low smoke and zero halogen properties, crucial for environments where life and equipment are at risk. A potential caveat is its specific application for conduit and trunking systems. This single-core, 2.5mm² brown cable is BASEC approved and designed for semi-flush exposed conduits, embedded conduits, and closed installation ducts, offering easy drawing into place while minimizing fire, smoke emission, and toxic fume hazards.

FAQs
What does 'Low Smoke Zero Halogen' mean for this cable?
It means that in the event of a fire, the cable is designed to emit very little smoke and no toxic halogenated gases, which improves visibility and reduces the risk of respiratory harm.
Is this cable suitable for outdoor use?
This cable is intended for use within conduits and trunking systems, typically in indoor or protected environments. Its suitability for direct outdoor exposure depends on the specific conduit system's rating and environmental conditions.
Can I use this brown cable for neutral or earth connections?
While the brown color is typically used for live conductors in many wiring systems, always refer to your local electrical regulations and installation standards to confirm the correct color coding for neutral and earth connections in your specific application.
What is the maximum current rating for this 2.5mm² cable?
The maximum current rating depends on factors such as installation method, ambient temperature, and grouping with other cables. Consult relevant electrical standards (e.g., BS 7671) or the manufacturer's technical data for precise current carrying capacities.
Is the 'Time 6491B' designation important?
Yes, '6491B' is a specific type designation for a Class 2 copper conductor, PVC insulated, LSZH sheathed cable, designed for use in conduits. The 'B' signifies the LSZH outer sheath.
Can this cable be used in flexible applications?
No, this is a single-core, rigid conductor cable designed for fixed installation within conduits and trunking, not for flexible or dynamic applications.
Troubleshooting
Cable is difficult to pull through conduit
Ensure the conduit is clear of debris. Use a suitable cable lubricant. Check for any sharp bends or kinks in the conduit path that may be causing friction.
Discoloration or damage to insulation during installation
Stop pulling immediately. Inspect the conduit for sharp edges or obstructions. Use a pulling grip designed for the cable size and ensure a smooth pulling action. Avoid excessive force.
Intermittent circuit connection
Check all termination points for secure connections. Ensure the cable is correctly stripped and terminated at both ends. Verify the cable integrity along its entire length if accessible.
Pros and Cons
Pros
- Enhanced safety in fire situations due to LSZH properties.
- Guaranteed quality and compliance with BASEC approval.
- Facilitates easy installation in pre-existing or new conduit systems.
- Suitable for environments where fire, smoke, and toxic fumes are a significant concern.
Cons
- Limited to use within conduit or trunking systems.
- Single-core design means it cannot be used for multi-conductor applications on its own.
- Specific color (brown) may require adherence to local wiring regulations for its intended use.
Setup, Compatibility & Care
Setup:
- Ensure the conduit or trunking system is clean and free of obstructions.
- Use appropriate cable pulling lubricants if necessary to facilitate smooth installation.
- Carefully feed the cable through the conduit, avoiding sharp bends or damage to the insulation.
- Terminate the cable according to relevant electrical standards and the requirements of the connected equipment.
Compatibility:
- Primarily designed for use within electrical conduits and trunking systems.
- Compatible with standard electrical connection accessories, junction boxes, and termination points suitable for 2.5mm² single-core cable.
- Verify compatibility with local electrical codes and regulations.
Care:
- The cable itself requires minimal care once installed within a protected conduit system.
- Regularly inspect the conduit and termination points for any signs of damage or wear during routine electrical maintenance.
