ELECTRICAL SYSTEMS
4.1 GENERAL
The electrical systems in your Tiara 43 have been designed and built to the recom-
mendations of the American Boat and Yacht Council (ABYC), the requirements of
the United States Coast Guard, and have received National Marine Manufactures
Association (NMMA) Yacht Certification. It has been developed to supply all the
boat’s electrical needs at the dock, at anchor, and underway. While we are not
attempting to describe all of the electrical engineering that went into the system,
we believe some understanding of the basics of it’s operation would help assure
trouble free operation.
All of the electrical functions on your boat are a part of three basic systems, 12V
D.C., 120/240V A.C., and bonding.
4.2 12V D.C. SYSTEM
4.2.1 Power supply
Power is supplied to the 12V D.C. system from two banks of batteries, an engine
bank, and a house bank. Each bank is comprised of wet flooded cell batteries
connected together to form a bank. Boats equipped with the optional D.C. to A.C.
inverter will have the number of batteries in the house bank increased by one, to
manage the increased loads possible from inverter usage.
The intent of your 12V D.C. system design is to provide a source of the basic
needed battery power to operate your vessel safely while underway, and a sec-
ond source for convenience and comfort items. It is expected that the engine
bank will provide the basic operating power, and that the house bank will provide
the convenience and comfort power, as well as power for other owner installed
