AC Multi-Meter
Use the arrow keys to scroll through digital
readouts for amperage (A), voltage (V),
cycles (hertz) (Hz) and watts (W).
• (A) Indicates the total amperage being
drawn through the AC MDP. It is the
total current level of all of the AC equip-
ment in operation at the time.
• (V) Indicates the voltage supplied to the
panel. Ideally the voltage should be
approximately 240 volts (230 for CE) but
never less than 208 volts.
• (Hz) Indicates cycles which should be
60 (50 for CE).
• (W) Indicates total watts being con-
sumed as a result voltage x amperage.
AC Main Breakers
The shore power or generator main breaker
protects the AC distribution. This breaker is
very sensitive. The resulting power surge
that occurs when connecting the dockside
cord or starting the generator may cause the
main breaker to trip. To avoid this surge,
always turn the selected main breaker to the
“OFF” position before plugging or unplug-
ging the shore power cord or starting or
stopping the generator.
The following components are protected by
either 120 or 240 Volt 60 Hz breakers for
domestic models. Certain export models
use only 220 Volt 50 Hz breakers for all com-
ponents:
240 Volt Circuits (Domestic Only)
Cabin Air Conditioning
Supplies electrical current directly to the
cabin air conditioner. This breaker will trip if
sea water is not being supplied to the air
conditioning unit. If this breaker trips, reset
and check for water flow out of the air condi-
tioning thru-hull. Refer to the air conditioner
owner’s manual for additional information.
Helm Air Conditioning
Supplies electrical current directly to the
helm air conditioner. This breaker will trip if
sea water is not being supplied to the air
conditioning unit. If this breaker trips, reset
and check for water flow out of the air condi-
tioning thru-hull. Refer to the air conditioner
owner’s manual for additional information.
Cooling Pump
The breaker supplies power to the cooling
pump for the air conditioners. This breaker
MUST be turned on before operating the air
conditioners.
House Charger
The house 40 amp battery charger charges
the house, electronics and bow thruster bat-
teries. This breaker should ALWAYS be on
whenever the boat is occupied and either
the shore power or generator is operating. It
is automatic and is equipped with an amme-
ter to monitor charging. See the battery
charger manual for more information.
Engine Charger
The engine 20 amp battery charger main-
tains the charge on the engine batteries. It
is automatic and is equipped with an amme-
ter to monitor charging. See the battery
charger manual for more information.
Water Heater
Supplies electrical current directly to the
water heater circuit. The water temperature
is automatically controlled by a thermostat in
the water heater control panel. Before oper-
ation, you must have water in the water
heater (see the water heater manual for
more information).
Cockpit Grill
Supplies electrical current to the cockpit grill.
This breaker should ONLY be on when the
grill is being used. See the grill manual for
more information.
