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.

Generator Amperage

Table 8 shows the maximum amps the generator can provide. DO NOT exceed the maximum amps as listed..

Table 8. Generator Maximum Amps

Rated Voltage	Maximum Amps
1Ø 120 Volt	155.5 X 2 amps (4 wire)
	168 amps X 2 (Zigzag)
1Ø 240 Volt	78.8 amps (4 wire)
	168 amps (Zigzag)
3Ø 240 Volt	168 amps
3Ø 480 Volt	84 amps

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.

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.
