(d) When the generator speed reaches 3000 to 3300 rpm (60 Hz generators),
the current in the condenser coil increases rapidly. This acts to stabilize the
output voltage of each coil. When the generator speed reaches its rated
speed, the generator output will be at its rated value.
(2) Voltage Fluctuations Under Load (refer to Figure 2-6)
(a) When output current (c) flows through the main coil to the appliance being
used, a magnetic flux is produced and serves to increase current (a) in the
condenser coil. As a result, the current flowing in the field coil increases
and the generator output voltage is prevented from decreasing.

(3) Full Power Switch (Dual Voltage Type) (refer to Figure 2-4)
(a) The full power switch provides both 120V and 240V dual voltages at full
rated power. The full rated power will be available from one 120V
receptacle and one 240V receptacle.
(b) Two main coils are wound over core of the stator. Each main coil outputs
half the rated power at the lower voltage (110V or 120V). These main coils
are wound so they are in the same phase. The full power switch
reconnects these main coils in parallel or in series.
(c) Refer to the circuit diagram in Figure 4. When the full power switch is set
for single lower voltage indication (110V or 120V), the switch position will
be as indicated by the lower coils line in the diagram.
