3.4 Ground Fault Circuit Interrupters
Certain receptacles on your boat contain Ground Fault Circuit Inter-
rupters (GFCI). The GFCI measures both the amount of current flowing
to the receptacle and the amount of current returning from the recep-
tacle, then compares the two values. If the values are not the same, the
GFCI instantly trips, shutting off power to the receptacle.
When someone receives an electrical shock through a GFCI recep-
tacle, the current flowing to the receptacle continues flowing through
the person’s body and into any grounded object the person is touching
or standing on. Thus, the current does not return from the receptacle
through the appropriate wire. The GFCI “sees” this difference in
current and shuts off power to the receptacle. This limits the amount
of time the person is being shocked to a brief moment, which can
reduce the amount of injury to the person.
Any electrical shock from the AC electrical system, even through a GFCI
receptacle, can cause death or serious injury. Always seek immediate
medical attention after receiving such a shock.
3.4.1 GFCI Receptacle Locations
Five GFCI receptacles are installed on your boat. Each one protects a
group of receptacles that can include both open outlets and those that
are already in use for built-in equipment. A GFCI receptacle is located:
• On the port side of the cockpit next to the salon entrance door, to
protect the exterior receptacles.
• On the forward starboard bulkhead in the salon, to protect the salon
and pilothouse receptacles.
• On the port forward bulkhead in the galley, to protect the galley
receptacles.
• Above the sink in the starboard head, to protect the receptacles
there, in the forward stateroom, in the third stateroom, and in the
stateroom companionway.
• Above the aft nightstand in the master stateroom, to protect the
receptacles there and in the port head.
