data plate ~ves the voltage, current and frequency rating of
the generator. An AC wiring decal is affixed to the inside of
the louver~ cover at the generator end. A diagram of the

Circuit Breaker
A circuit breaker is installed on all single phase
WFSTERBEK£ generators. This circuit breaker will
automatically disconnect generator power in case of an
el:ectrical overload: The circuit breaker can be manually shut
off
when s~rvicing the generator to ensure that no power is
coming into theboat.
NDTE: rhls circuit breaker is available as a WESTERBEKE
add-on1dtfor earliet. model generators; contact your
WESTERBEKE dealer.
