What gauge is used for the signal/data pair on Mid NMEA 2000 cable?

Explanation:
In NMEA 2000, the data lines carried by the Mid cable are a shielded two‑conductor pair, and this signal/data pair uses 20 AWG conductors. This gauge provides a good balance between keeping the voltage drop and losses low on typical vessel lengths while still allowing a flexible, easy-to-install cable. Heavier gauges (like 16 or 18 AWG) are generally used for the bus power, not the data pair, and a smaller gauge (such as 22 AWG) would raise resistance and increase susceptibility to noise. So the Mid NMEA 2000 data pair is 20 gauge.
