Product Description
Prysmian 6242Y 2.5mm² twin and earth cable, supplied on a 100-metre drum, rated to 300/500V for domestic installation work.
Key specs
- Conductor: 2.5mm² solid copper core, giving rigidity for straightforward routing during first fix.
- Drum length: 100 metres — a single continuous run removes joins on longer circuit runs, cutting connection points and associated fault risk.
- Voltage rating: 300/500V.
- Sheath colour: Grey, flat twin and earth profile.
- Profile: Flat cross-section sits flush when chased into plaster, simplifying installation and finishing.
Why the 100m drum matters on site
For CCTV installers and integrators running mains supply to NVRs, PSUs or powered enclosures alongside data cabling, a single 100m drum means fewer joints to terminate and inspect across a job — useful when pulling power to multiple camera locations or a plant room from one reel. Solid core construction keeps the cable stable in conduit or under clips rather than kinking back, which matters when routing alongside low-voltage CCTV cabling in the same first-fix.
Specify by drum length and colour when ordering to match existing runs or building regs documentation — this listing is the grey 100m, 2.5mm² variant.
