Voltage Selector Switch; Some Notes About Power Cords - DUROMAX XP4400 Owner's Manual

Once you have determined what electrical devices you will be powering with the generator,
connect these devices according to the following procedure:
1. Plug in each electrical device with the device turned off.
a. NOTE: Be sure to attach appliances to the correct receptacle (outlet). Connect
standard 120 Volt, single phase, 60 Hz loads only to the 120 Volt receptacle.
b. Connect 120/240 Volt, single phase, 60Hz loads with NEMA L14-30 plug only
to the 120/240 Volt receptacle See Figure 11 for a depiction of each of these
receptacles.
2. Switch the circuit breaker to the "ON" position.
Turn on the connected electrical devices in the order of the amount of power they
3.
require beginning with the device with the highest rated Wattage requirement.
CAUTION:
Do not connect 50Hz or 3-phase loads to the generator.

VOLTAGE SELECTOR SWITCH

The voltage selector switches the main power carrying 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 a 120V appliance is being connected select
the "120V ONLY" position.
Change the Voltage Selector Switch after turning the AC circuit breaker to OFF. The
generator may be damaged if the Voltage Selector Switch is changed with the breaker on.

SOME NOTES ABOUT POWER CORDS

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 Figure 12 for recommended cords based on the power requirement of the
electrical device.
