GACAN limits use of how many different gauges?

Limiting the number of conductor gauges to two keeps the electrical characteristics of a run predictable and manageable. When only two sizes are used, resistance, inductance, and capacitance stay within a narrow range, which makes terminations, splicing, and testing more straightforward and reliable. Introducing a third or fourth gauge would introduce more variability in impedance and other properties, making it harder to certify performance and maintain consistency across the installation. That balance—enough flexibility to accommodate practical needs (such as different gauges for different functions) while avoiding excessive complexity—leads to allowing two gauges. Using only one gauge would be too restrictive for common installations, and three or four gauges would complicate design and testing without real benefit.
