To chosse the right cable for LED lighting, The cross-sectional area of a wire is an important factor for determining its current-carrying capacity.
American Wire Gauge, Know as AWG -which is used as a standard method of denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge.
As below, The AWG to Square mm table is for a single, solid, round conductor. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter.
The higher the number – the thinner the wire. The most common wire with AWG are 18,20,22.
