WARNING - Only change the Voltage Selector Switch with the main AC Circuit Breaker
OFF. The generator can be seriously damaged if the Voltage Selector Switch is changed
with the breaker ON.
Voltage Selector Switch
Choosing the right power cord
This generator features Power Boost Technology, which gives the user
the ability to double the power in the generator for more heavy duty
applications.
The voltage selector switches the dual 120v AC windings of the generator
to produce “120V ONLY” or “120/240V”. If a 240V appliance is connected
to the 4-prong receptacle, the switch must be in the “120/240V” position.
If only 120V appliances are being connected to the generator select the
“120V ONLY” position to double the 120v amperage and automatically
balance the load.
Long or thin cords can drain the power provided to an electrical device by the generator. When
using such cords, allow for a slightly higher rated wattage requirement for the electrical device. See
table below for recommended cords based on the power requirement of the electrical device.
