Two 6 mm² class 2 copper conductors, 7 strands of 1.04 mm per core, PVC insulated and sheathed to 450/750 V — the size half the trade still orders as 7/.044. 46 A on reference method C with both conductors loaded, 3.08 Ω/km, about 107 kg of copper per kilometre of cable. 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.

Two cores means line and neutral, and nothing else. The earth has to come from somewhere: steel conduit, a separate earth wire pulled alongside, or the trunking. Answer that first and the 2 core / 3 core question answers itself. The people who order this size are contractors dropping a submain to a shop or an upper portion, and electricians putting in a dedicated point for a big AC or a cooking range — jobs at 30 to 46 A on a 220 V single-phase supply, where 4 mm² is short at 36 A and 10 mm² is more copper than the load asks for.
Main board to a shop, annexe or upper-portion board, where conduit or a separate earth wire carries the earth path. Up to 46 A.
A dedicated feed to a 2-ton AC or a cooking range on its own breaker, pulled in conduit with the earth run separately.
Fixed conduit runs to single-phase water pumps and booster sets that stay bolted where they are.
Heat sets one limit, run length sets the other, and on a submain the length is usually what bites. Voltage drop is current × length × 7.3 mV/A/m, divided by 1000. A 32 A submain over a 25 m run drops 32 × 25 × 7.3 ÷ 1000 = 5.8 V, which is 2.7% of 220 V — inside the 5% BS 7671 allows on a power circuit, 11 V here. Load the same cable to its full 46 A and the drop hits 11 V at about 33 m: 11000 ÷ (46 × 7.3) = 32.8. Past that distance the length picks the size, not the load, and the next step is 10mm 2 core cable at 63 A and 4.4 mV/A/m. Check your own run on the voltage drop calculator.
