What is the current capacity of a heavy cable?

Explanation:
The heavy cable in an NMEA 2000 network is the power trunk and is designed to carry more current than lighter drop cables. Its current capacity is eight amps. This rating comes from its larger conductor size and insulation, which are chosen to keep heat rise and voltage drop within safe limits over typical boat lengths while supplying power to devices along the bus. Numbers like six, ten, or twelve amps aren’t the standard rating for this heavy trunk cable, with eight amps being the defined value for safe, continuous operation.
