In Australia, as elsewhere, cable size is not about the physical thickness of the plastic sheath. It’s about the cross-sectional area of the inside, measured in square millimetres (mm²). The larger the number, the thicker the copper, and the more electrical current (amperage) it can safely carry without overheating.

How much current (Amps) the cable can handle before the insulation melts.
