GENERATOR OUTPUTS
GENERATOR OUTPUT VOLTAGES
A wide range of voltages are available to supply voltage for
many different applications. Voltages are selected by using
the voltage selector switch (Figure 13). To obtain some of
the voltages as listed in Table 7 (see below) will require a
fine adjustment using the voltage regulator (VR) control
knob located on the control panel.
Voltage Selector Switch
The voltage selector switch (Figure 13) is located above
the output terminal panel’s Hard Wire Hook-up Panel. It
has been provided for ease of voltage selection.
Figure 13. Voltage Selector Switch
Voltage Selector Switch Locking Button
The voltage selector switch has a locking button to protect
the generator and load from being switched while the
engine is running. To lock the voltage selector switch, press
and hold the red button located at the bottom of the switch.
CAUTION
NEVER change the position of the voltage selector
switch while the engine is running. ALWAYS place
circuit breaker in the OFF position before selecting
voltage.

Generator Amperage
Table 8 shows the maximum amps the generator can
provide. DO NOT exceed the maximum amps as listed..
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.
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 to exceed the available current capability at
the receptacles.
