There isn't a specific diameter. The thicker the wire the more current it can convey. This diameter will be part of your calculations for your circuit.
here are the specification about that cable No. of copper wire Bare annealed copper Dia. of copper wire Nom : 0.50mm Type of insulation Natural color solid Polyethylene Insulation thickness Std : 1.30mm Diameter over insulation Nom : 3.1mm Diameter over outer conductor (wire braids) Nom : 0.14mm Min : 0.132mm No of layer wire braids 0.12mm x 7 x 16 copper Type of sheath PVC Black Sheath thickness Nom : 0.80mm Overall diameter of cable Max : 6.50mm Nom : 6.20mm Min : 6.00mm

When copper is pulled into thin wires, it is called copper wire drawing. This process involves passing the copper through a series of decreasing diameter dies to gradually reduce its diameter and form a thin wire.
14SWG copper wire has a diameter of 1.628 mm.
I know two kind of machines for copper recycling. One is cable granulator which is used for making copper core into small granules by grinding cable and separating PVC. This is a ideal machine for miscellaneous cable. The other is copper wire stripper which is to strip the PVC cover and you get the entire copper core. This is widely used in various copper wire various diameters.
Copper wire
A caliper is commonly used to measure the diameter of a copper wire. It can provide precise measurements by using its jaws to grasp the wire and providing a reading of the diameter on its scale.
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
The larger in diameter the wire is, the larger the current carrying capacity the wire has.
Coaxial cable
Using the formula for resistance of a wire (R = ρ * (L/A)), we can find the resistivity ratio (ρ_aluminum / ρ_copper) as 1.7 since the total current in both wires is the same and the lengths are different. Knowing that the resistivity of copper is 1.7 times less than that of aluminum, and given that resistivity is inversely proportional to cross-sectional area, the diameter of the copper wire will be √(1.7) = 1.3 times the diameter of the aluminum wire. Since the diameter of the aluminum wire is 2mm, the diameter of the copper wire will be 2mm * 1.3 = 2.6mm.
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
