Bc Generator Single Phase; Circuit Breaker - Westerbeke 5.0KW BCD Operator's Manual

Be GENERATOR SINGLE PHASE
NOTE: WESTERBEKE recommends that the following generator tests
and adjustments be peiformed by a qualified technician.
DESCRIPTION
The BC generator is a brushless, self-excited generator which
requires only the driving force of the engine to produce an
AC output. The stator houses two sets of windings; the main
stator windings and the exciter windings. When the generator
is started, residual magnetism in the four rotating poles
induces a current in the stator which then generates an even
larger current in the exciter windings. This mutual build up of
current in the four rotating poles and in the exciter windings
quickly reaches the saturation point of the capacitor(s) and a
regulated energy field is then maintained in the stator. At the
same time, this regulated field produces a steady voltage in
the stator windings which can then be drawn off the genera-
tor's AC terminals to operate AC equipment. The generator is
a single-phase, reconncctable 120 volt AC two-wire or
120/240
voltAC three-wire, at 60 hertz; or 110 yoltAC two-
Wire or 220 voltAC two-wire, at 50 hertz. Refer to the
SPECIFICATIONS section of this manual for generator rat-
ings. The generator's data plate gives the voltage, current and
frequency rating of the generator. An AC wiring decal is
affixed to the inside of the louvered cover at the generator
end. A diagram of the various AC voltage connections is pro-
vided on the decal. An Integral Controller (IC) is mounted
inside the generator and supplies a continuous DC charge to
the generators starting battery when the generator is running.
For more information see the IN1EGRAL CONTROLLER
DC CHARGER section in this manual.
Circuit Breaker
A circuit breaker is installed on all single phase
WESTERBEKE generators. This circuit breaker will auto-
matically disconnect generator power in case of an electrical
overload. The circuit breaker can be manually shut off when
servicing the generator to ensure that no power is coming
into the boat.
NOTE: This circuit breaker is available as a VVESTERBEKE
add-on kit for earlier model generators; contact your
WESTERBEKE dealer.
