AC ELECTRICAL SYSTEM SECTION 3
As the chart indicates, appliances that use a motor or a heating element
draw relatively large amounts of current. Therefore, be especially careful when
using curling irons, toasters, coffee makers, hair dryers, food mixers or similar
types of AC powered devices. Do not use too many of these types of devices at
the same time.
Bonding System
Your boat is equipped with a comprehensive metallic bonding system that
interconnects all underwater equipment and thru-hull fittings. The bonding
system ensures that the “cases” of all metallic equipment onboard your boat,
including the fittings, are at the same electrical potential. This minimizes
corrosion of the underwater fittings caused by stray electrical currents.
Included within this bonding system are sacrificial zinc anodes that have been
installed on each of the boat’s propeller shafts and onto the underwater portion
of the boat’s transom. These anodes corrode and deteriorate before the boat’s
underwater fittings and provide a visual reference to the level of stray current to
which your boat is being exposed.
Your boat’s 12-volt DC electrical system, AC electrical system, and the batteries’
negative leads are all connected to the bonding system through bus bars. The
bus bars are located in the engine room and bilge area and are connected to the
transom-mounted zinc plate.
Do not tamper with or modify the boat’s bonding system. Doing so could
threaten the integrity of the system.
Monitor the condition of your boat’s zinc anodes. Replace the zinc
anodes when they have deteriorated to 50% of their original size. Do
not allow the zinc anodes to completely deteriorate. Refer to Section 7
- Maintenance Schedule for recommended inspection intervals.
NOTE: Damage resulting from stray current or galvanic corrosion is NOT covered
under the Carver limited warranty.
