UNIT CAPABILITIES
This generator is equipped with Switchless Full Power.
This feature allows the full output of the unit to be drawn
from either the 120 volt receptacles or the 240 volt recep-
tacle without reconnecting the generator. This feature is
extermly helpful when powering larger 120 volt loads. The
diagram below represents the 5500 watt (rated output)
generator
Reference A = 120 Volt Full Power Receptacle
NEMA 5-50 (120V-50A)
Reference B & C = 120 Volt Receptacle
B - NEMA 5-20 (120V-20A)
C - NEMA 5-20 (120V-20A)
Reference D = 120/240 Volt Twistlock Receptacle
NEMA L14-30 (120/240V-30A)
With the receptacles wired in this confi guration the opera-
tor can use up to the nameplate rating of unit (5500 Watts)
using any combination of the 120 Volt receptacles and still
have the 240 volt power available. Remember no matter
what combination of 120 volt or 240 volt power utilized you
can not exceed the 5500 watt rating of the unit..
Starting Electric Motors - Electric motors require much
more current (amps) to start them than to run them.
Some motors, particularly low cost split-phase motors, are
very hard to start and require 5 to 7 times as much current
to start them as to run them. Capacitor motors are easier
to start and usually require 2 to 4 times as much current to
start them as to run them. Repulsion Induction motors are
the easiest to start and usually require 1 1/2 to 2 1/2 times
as much to start them as to run them.
Most fractional horsepower motors take about the same
amount of current to run them whether they are of Repul-
sion-Induction (RI), Capacitor (Cap), or Split-Phase (SP)
type. The chart below shows the approximate current re-
quired to start and run various types and sizes of 120 volt
60 cycle electric motors under average load conditions.

The fi gures given above are for an average load such as
a blower or fan. If the electric motor is connected to a
hard starting load such as an air compressor, it will require
more starting current. If it is connected to a light load,
or no load such as a power saw, it will require less start-
ing current. The exact requirement will also vary with the
brand or design of the motor.
Self-excited generators respond to severe overload-
ing differently than the utility power. When overloaded,
the engine is not able to supply enough power to bring
the electric motor up to operating speed. The generator
responds with high initial starting current, but the engine
speed drops sharply. The overload may stall the engine. If
allowed to operate at very low speeds, the electric motor
starting winding will burn out in a short time. The genera-
tor winding might also be damaged.
CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER THESE
CONDITIONS MAY RESULT IN DAMAGING THE
GENERATOR STATOR AS WELL AS THE MOTOR
WINDING.
Because the heavy surge of current required for starting
motors is required for only an instant, the generator will
not be damaged if it can bring the motor up to speed in a
few seconds of time. If diffi culty is experienced in starting
motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.

Trying to start a larger motor or higher code (ie. J or K)
motor may result in damage to both the generator and the
electric motor especially 120 volt motors.
