Depending on the AC power load your boat re-
quires and the power available from the shore
supply or the generator, you may not be able to
operate all 120 volt AC accessories at one time.
POWER MANAGEMENT PRACTICES may need to be
observed particularly when supplying power from
the generator. You should be aware of the load
each accessory draws and make sure you don’t
overload the circuit.
The table in this section will assist you in docu-
menting the load AC accessories on your boat

require and managing the electrical load on each
circuit. An owner’s manual for each AC accessory
installed on your boat at the factory has been
included with your boat. Additionally, you should
make sure you have the manuals for accessories
installed by your dealer or that you bring aboard.
The specication section of the owner’s manual
will provide the wattage or amperage the acces-
sory requires. Enter the load requirements in the
table provided and use the information as a quick
reference tool to calculate the electrical load. If
only watts are given in the specications, divide
the watts by the voltage to determine the amps.
