TYPICAL (AC) ALTERNATING CURRENT-INFORMATION
OVERVIEW
Alternating current sometimes called AC current is
brought on board through the use of a dockside shore-
power) cordl/reel system or produced on board through
the generator. Just as a residential home uses 120/240
volts to run various household appliances and equip-
ment the same holds true on your yacht.
With AC current electrons “cycle” in one direction a
short distance and reverse themselves traveling in the
opposite direction. Th
is is how AC became known as
alternating current. Th
e rate that the current reverses
itself is referred to as frequency. In the United States the
alternating current frequency is 60 cycles per second.
Overseas a 50 cycle frequency per second is standard.
Component specifi cations must match the country’s
frequency.
BASIC ELECTRICAL TERMS
Voltage is a measurement of the electrical potential that
an electrical power source contains for doing some type
of work for us. Th
ink of it as electrical pressure. An ex-
ample might be your yacht’s battery.
Amperage is a particular amount of electricity fl owing
through some part of a circuit. Th
ink of it as the rate of
electrical fl ow through your yacht’s wiring.
Resistance is measured in ohms and inhibits the electri-
cal fl ow through a circuit. An example would possibly
be an incandescent light bulb. Th
e resistance in the light
bulb element allows it to glow and brighten the cabin
along with giving off heat.
It is important that you understand and respect the
alternating current system used on board. Be sure
to read and follow any danger, warning, or caution
labels in reference to the yacht’s electrical system or
individual equipment components. Most of all, use
common sense!
Th
e dockside cord is the basic component used to de-
liver up to 50 amps of electricity from the marina dock
power box to the yacht itself through the cord reel sys-
tem.
Before plugging in the dockside power cord check to
see that all yacht AC breakers are off . Th
is includes
the incoming as well as both the main and equipment
breakers at the AC ship’s control panel. See the AC panel
illustration later in this chapter.
When connecting the shore power cord be sure to twist
the cord into the marina inlet plug. Th
is motion will lock
the plug in the socket.
Th
ere may be several types of inlet plugs located at the
marina dock power center. Be advised that the 30 amp
plug is much smaller looking and the 50 amp cord will
not physically fi t it.
Also, marina dock power centers normally have breakers
that must be activated aft er installing the dockside cord.
Make sure the dockside cord has enough slack to weather
changing tides if applicable and at the same time does not
come in contact with the water. Check with the marina
dockmaster for more information on their shore power
operation and requirements.
Before attempting to disconnect the shore power cord
turn off all equipment and main AC breakers on the
ship’s control panel to prevent any component damage.
When disconnecting the shore power cord fi rst turn the
breaker to the “off ” position at the marina dock power
center. Th
en remove the dockside cord from the marina
outlet.
