General about marine DC system
G.2 General about marine DC system
G.2.1 Wiring systems
There are two basic wiring topologies used for marine DC system grounding:
Two-Wire Return System
and
One Pole Grounded Return System
.
G.2.2 Two-wire Return System
This configuration implies that no part of the circuit, in particular the battery
negative, is connected to any ground potential or equipment. The system is
totally isolated and includes engine sensors, starter motors etc. This
arrangement is preferred for steel and aluminum vessels.
