Voltage Selector Switch
Voltages are selected by using the voltage selector switch
(Figure 12) which is located above the output terminal
panel's Hard Wire Hook-Up Panel. This switch has been
provided for ease of voltage selection.

CAUTION
NEVER change the position of the voltage selector
switch while the engine is running. ALWAYS place
the circuit breaker in the OFF position before selecting
voltage.
Voltage Regulator
To obtain some of the voltages listed in Table 7 will require
a fine adjustment using the voltage regulator (VR) control
knob located on the control panel.

GFCI Receptacle Load Capability
The load capability of the GFCI receptacles is directly
related to the voltage being supplied at either the output
terminals or the three twist-lock auxiliary receptacles.
Figure 17, Table 9 and Table 10 show what amount of
current is available at the GFCI receptacles when the output
terminals and twist-lock receptacles are in use. Be careful
that your load does not exceed the available current
capability at the receptacles.
