illustration purposes.
ELCI (Equipment Leakage Circuit Interrupter)
Once the shore power cords are attached to the
marina dock side power and the vessel dock side
power inlets voltage when activated travels to the
ELCI actuator enclosure which is located on the
battery management board in the bilge (sump).
Once through the ELCI power continues to the
ship’s main AC control panel culminating at the
shore power main and as they are activated using
the auxiliary equipment breakers.
Note that both shore line breakers above are of
a single throw double pole design. Both break-
ers above feature leakage fault technology. If the
30 amp ELCI breaker “trips” find the cause of the
problem before resetting the breaker.
ELCI stands for “Equipment Leakage Circuit Inter-
rupter”. There are two potential failures in a boat’s
electrical system that can put people on or around
a vessel at risk of lethal electrical shock. In a prop-
erly functioning marine electrical system, the same
amount of AC current flows in the hot and neutral
wires.
However, should electricity “leak” from this intend-
ed path in these two wires to ground, this condi-
tion is referred to as a “ground fault”. An example
of this is an insulation failure in the wiring of an
appliance.
Furthermore, a ground fault can occur when the
grounding path is broke through a loose connec-
tion or broken wire. As an example a shore power
ground wire may fail due to fatigue caused by con-
stant motion and stress. Faulty grounds can go un-
detected; a simple continuity test may not reveal
problems.
