Precise wire sizing is essential for circuit breakers as it helps determine how much electrical current can flow through it and how much resistance it has. The higher the gauge number, the smaller the diameter and the thinner the wire. American Wire Gauge Conductor Size Table. American wire gauge â¦ The smallest AWG size is 40 and the largest is 0000 (4/0). That is, the electric current tends to flow at the "skin" of the conductor. d n (in) = 0.005 in × 92 (36-n)/39. 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.
