#US WIRE GAUGE CHART SKIN#

Resistance acts upon both a direct current and alternating current to create a “skin effect.” Simply put, as a signal frequency increases, the current flow of the wire concentrates toward the skin (outside) of the conductor. AWG and ResistanceĪWG is also related to resistance. This is why AWG wires are always slightly bigger in diameter than solid wire. While you can tightly wind or braid wires, there will always be some type of small gap between the strands. Since smaller gauge sizes are more durable and flexible, it’s common practice to use them with higher AWG numbers when stranding conductors for bending or vibration applications. As a general rule of thumb, the higher the AWG number, the smaller (or thinner) the wire will be. In fact, jacketing and insulation are not size determining factors of AWG. Such measurements are made on only the wire and not on the wire’s jacketing or insulation. Circular mil is the area of a 1/1000 (or 1 mil) diameter circle. Oftentimes the term “circular mil” is used. AWG is determined by first figuring out the radius of a wire squared, time pi. Since 1857, wire gauge to MM2 made determining a wire’s current-carrying ratings easier.

As a general rule of thumb, for every 6 gauge decrease, the wire diameter doubles, and every 3 gauge decrease doubles the cross-sectional area.
