If you’re looking to unravel the mysteries of sizing automotive wiring, or determining a size of an international cable where you need a simple Cable Size Calculator, then you’ve come to the right place!

From wiring speakers to wiring a 3000W inverter, you need to get the cable sizing right.

Cable size terminology in Australia is extremely confusing at best.

American wire gauge (AWG) is a standardised wire gauge system used since 1857 predominantly in North America. The cross-sectional area of each gauge is an important factor for determining its current-carrying ampacity.  Increasing gauge numbers denote decreasing wire diameters, which is like many other non-metric gauging systems such as British Standard Wire Gauge (SWG), but unlike IEC 60228, the metric wire-size standard used in most parts of the world.

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG.

Hopefully our Cable Stranding Chart can help.
