To answer questions like, “how thick is 4 gauge wire?”, you need to understand how the AWG wire gauge system works. In the custom cable manufacturing industry, exactness matters which is why even the smallest degree of error needs to be corrected in a design before ever moving forward with production. This standardization helps our wire engineers start with materials with known electrical properties to provide the most effective designs possible. Wire diameter is critical in custom wire harness design as it helps to determine how much of an electrical load and the level of resistance, expressed in ohms (Ω). Non-ferrous metals, like aluminum and copper, make excellent conductors. It’s important to note that the AWG applies to round, solid, and non-ferrous wires.
The AWG sets gauges in order to have a unifying system of measure with wires and conductors. The AWG sets corresponding numbers to different diameters of wire gauge.Ĭontrary to what you might think, the lower AWG numbers actually correspond to wires with higher diameters and the larger numbers in the AWG wire gauge size chart correspond to smaller diameters of wire. The diameter of a wire is expressed in a unit known as a gauge, as set by the American Wire Gauge (AWG).

In today’s LiveWire spotlight, we’ll showcase a complete wire gauge guide focused on topics like wire gauge sizes, how to measure wire gauge, and how to choose the right wire gauge in custom cabling applications.įirst up, what does gauge mean in wire harness design? Wires are produced in a wide variety of widths in order to meet the needs of the project. That’s why our designers take such care when designing custom wiring harnesses to incorporate the perfect gauges to meet the needs of the project. Wire gauges help determine the effectiveness, as well as the costs of the overall design.
