That depends upon the maximum amperage expected through the cable (which generally depends upon the usage): Lighting circuits use 1.0 mm2 or 1.5 mm2 Ring mains use 2.5 mm2 Cookers and showers use 6.0 mm2 If you are unsure, get a qualified electrician to install the cable you need (recommended).

On a 230 v supply assuming a volt-drop of 5% that is 11.5 v, so the maximum cable resistance is 11.5 / 40 in ohms, 0.2875 ohms so for 1000 metres of cable in total you need a cable that has 0.0002875 ohms of resistance per metre. Copper with a cross-section of 1 mm2 has resistance of 0.0168 ohms per metre so the size of cable needed is 0.0168 / 0.0002875 mm2, which is 58.43 mm2, so a cable of 60 mm2 should be selected.
On a 230-volt circuit, the cable should be suitable for 13 amps. The size is 1.25 mm2 or 1.5 mm2.

Cable for 19 amps continuous should have a cross-section area of 6 mm2.
The cable size is : 4*25 mm2

avg strength of concrete is 20 N/mm2 i,e, 95% of the tested ones gives 20n/mm2
Approximate overall diameter of the wire is 12.8 mm. If you are looking for metric wire size 95 mm2. 187500 circular mils.
