What gauge is used for the power pair on Mid NMEA 2000 cable?

Explanation:
In an NMEA 2000 network, power is carried on a dedicated pair in the trunk to supply onboard devices. The gauge used for that power pair in the Mid NMEA 2000 cable is 16 AWG. This size provides enough current-carrying capacity for typical marine electronics while keeping voltage drop within acceptable limits over the length of a mid-length run. Using smaller wire (like 18 or 20 AWG) would have higher resistance and greater voltage drop, risking undervoltage to devices as more loads are added. A larger wire (like 15 AWG) would be unnecessary for standard installations and adds unnecessary bulk and cost. So 16 AWG balances safety, performance, and practicality for the power distribution on the Mid cable. The CAN data lines run separately from this power pair and do not affect the gauge choice for power.
