What is the maximum current in any leg of an NMEA 2000 backbone using Heavy Cable?

Explanation:
The necessary idea is how power is carried along the NMEA 2000 backbone. Heavy Cable on the backbone is rated to carry up to 8 amperes per leg. This per-leg limit keeps voltage drop reasonable and prevents the conductors from overheating as devices tap power along the trunk. Therefore, the maximum current that can safely flow in any single backbone leg when using Heavy Cable is 8 amperes. Values like 6 or 4 are simply lower than the rated maximum, and 12 would exceed the rating and risk damage.
