ELECTRICAL SYSTEM
The electrical system on your catamaran consists of three major components: the battery system, wiring and cir-
cuit protection, and accessories. It is important that you understand the principles of the electrical system, so that you
can protect the components and troubleshoot any problems you experience.
BATTERY SYSTEM
Your World Cat is equipped with three batteries, excluding the 320 EC and 330 TE which have four. Two of the
batteries are dedicated as “cranking batteries”; the third bank controls the DC accessories and is commonly referred
to as the “house” bank. To help maintain your batteries, a management system is installed on your boat. This system,
controlled by the panel shown below, enables you to engage or disconnect the batteries, distribute electrical charge,
and parallel batteries in the event of a failure. Chapter 5 of this manual will provide details regarding the location and
wiring of your batteries and management panel.
BATTERY DISTRIBUTION
The drawing above illustrates the normal operating position for the battery management panel. The “PORT
START”, “STBD START”, and “HOUSE” switches as well as the “DC MAIN” breaker are in the “ON” posi-
tion and the “EMERG PARALLEL” is “OFF”. In this position, you are supplying power to the engines
through the cranking leads and to the DC accessories through the 50 Amp “DC MAIN” breaker. When you
have finished your trip, turn the “PORT START”, “STBD START” and “HOUSE” switches off prior to leaving
the boat. The “DC MAIN” can remain “ON” at all times.
