The size an electrician reaches for when a single-phase circuit has outgrown 6mm²: an instant geyser, a ducted AC point, a kitchen carrying an oven and a hob on one feed, or a short submain to a floor board. Two 10mm² class 2 conductors, 7 strands of 1.35 mm each — the build the trade still orders as 7/.052 — carrying 63 A on two loaded conductors at 450/750 V, 1.83 Ω/km, 4.4 mV/A/m. Drawn on the Pilone line in Lahore.

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 |

| Nominal area | 10 mm² × 2 cores |
| Strand construction | 7/1.35 mm per core (typical) |
| Max conductor resistance at 20°C | 1.83 Ω/km |
| Current capacity (method C, 2 loaded) | 63 A |
| Voltage drop | 4.4 mV/A/m |
| Voltage rating | 450/750 V |
| Insulation / sheath | PVC / PVC, 70°C conductor rating |
| Conductor copper weight | ≈ 178 kg/km (2 × 88.9 kg/km) |
| Reference standards | IEC 60228 (conductors), IEC 60227 (PVC cables) |
Worked example, from the voltage-drop figure in the table. A 50 A feed to a sub-board, run 20 m from the main panel, loses 50 × 20 × 4.4 ÷ 1000 = 4.4 V — 2% of a 220 V supply, inside the 5% BS 7671 allows on a power circuit, which is 11 V here. Load the cable to its full 63 A and that 11 V is spent at about 40 m: 11 ÷ (63 × 4.4 ÷ 1000) = 39.7 m. Beyond that it is the metres deciding the size, not the amps — the same 63 A on 16mm 2 core cable at 2.8 mV/A/m reaches 11 V at about 62 m.
One heavy appliance on its own breaker, where 6mm² at 46 A leaves no headroom. Read the rating plate, then size the breaker to it.
A single feed to a kitchen board carrying oven, hob and water heater together, rather than three long runs from the main panel.
A short single-phase submain from the main panel to a floor board, a servant quarter or a shop front, inside the 40 m the drop allows at full load.
