A: Wire gauges used in a wiring harness typically range from around 24 AWG (American Wire Gauge) to 8 AWG, with 24 AWG finer and 8 AWG thicker. The choice of wire gauge depends on factors like the current-carrying capacity, voltage drop, and the specific application’s requirements. Thinner gauges are suitable for low-current signal wires, while thicker gauges are used for higher-current power distribution. Remember that these ranges can vary based on the specific industry and application.
