Wire gauge is extremely important to the aircraft that InterConnect Wiring supports. Wire gauge is the measurement of the diameter of a wire, or the thickness of the wire. There are various wire gauges used within UH-60 wiring harnesses, F-15 wiring harnesses, C-130 electrical wiring harnesses, etc.
The thickness determines the amount of electrical current a wire can safely carry. Wire gauge is referenced as AWG behind a number. AWG stands for American Wire Gauge. So, 22 AWG is 22 gauge wire. To make things a little more confusing, a wire gauge that is a larger number, such as 22 AWG or 24 AWG, is actually a smaller diameter wire. In contrast, a 4 AWG or 8 AWG is a much larger wire.
Typically, in an F-16 wiring harness, matrix assembly, or cockpit panel, the wire gauges used most often are 20 AWG and 22 AWG. Wire gauge is used to measure both the electrical and non-electrical characteristics of wires; this is important to electrical wiring and to structural cable. The American Wire Gauge, developed by Messrs Brown & Sharpe in 1855 is what is primarily used in the United States.
