Backbone
Power the NMEA 2000 network
The network requires its own 12 V DC power supply, protected by a 3 A fuse.
For smaller systems, connect power at any location in the backbone.
For larger systems, connect power at a central point in the backbone to balance the voltage drop
of the network. Make the installation such that the load/current draw on each side of the power
node is equal.
