Four 1.5 mm² class 5 conductors in one sheath — three phases plus neutral, or three control circuits plus a common, without pulling four separate wires. 30 strands of 0.25 mm per core, PVC to 300/500 V, tabulated at 17.5 A with three loaded conductors on method C at 30°C. That is about 12 kVA on a 400 V three-phase supply. Panel builders, pump installers and event crews buy this size: it is the smallest four core that still takes a proper crimp and survives being rolled up every week.
Prices track the daily copper rate. Coil and bulk pricing on request.
Check the coil before you pay for it
Every coil leaves our factory with a QR code printed on the packaging. Scan it and the factory record for that batch opens: brand, cable size, batch number, year of manufacture and conductor. Compare the batch number on screen with the one printed on your coil — if the two do not match, it did not come from us.
| Property | Value |
|---|---|
| Conductor | Plain annealed copper, class 5 flexible stranded |
| Nominal area | 1.5 mm² × 4 cores |
| Strand construction | 30 / 0.25 mm per core (typical) |
| Max conductor resistance at 20°C | 13.3 Ω/km |
| Current capacity (method C, 3 loaded) | 17.5 A |
| Voltage drop | 29 mV/A/m |
| Voltage rating | 300/500 V |
| Insulation / sheath | PVC / PVC, 70°C conductor rating |
| Conductor copper weight | ≈ 53.2 kg/km (4 × 13.3 kg/km per core) |
| Reference standards | IEC 60228 (conductors), IEC 60227 (PVC cables) |
Voltage drop is current × length × 29 mV/A/m ÷ 1000. A panel circuit drawing 10 A over a 25 m run drops 10 × 25 × 29 ÷ 1000 = 7.25 V, which is 1.8% of 400 V — comfortably inside the 5% BS 7671 allows on a power circuit, 20 V here. At the cable's full 17.5 A that same 20 V arrives at 20 000 ÷ (17.5 × 29) = 39 m. Past 39 m at full load the run length picks the size, not the current.
Runs between panels, contactors, timers and small drives, where four separate wires would be four times the labour and four times the glanding.
Borewell and booster pumps drawing under 17.5 A per phase — three phases plus earth on one flexible tail from the starter.
Gear that is coiled, carried and re-rigged. Class 5 stranding takes that repeated bending; class 2 conductors harden and crack at the flex point.
Who buys this size: switchgear and panel shops, pump installers, and the event and workshop trade. The circuit it suits is a small three-phase one — a 400 V motor or panel feed under 17.5 A per phase — or a single-phase run that needs a spare core for a switch line or a pilot. For a fixed run inside conduit that never moves, the class 2 standard build costs less for the same copper and pulls in easier; class 5 earns its price only where the cable bends after installation. Above 17.5 A per phase, step up: 2.5mm 4 core flexible cable at 24 A is the next one we make, then 4mm 4 core flexible cable at 32 A.
