ADDING
LOADS
Follow
the appropriate procedure for adding either AC
loads or
DC
loads.
Continuous overloading
can
cause
kiBi3I
high operating temperatures that
could damage fhe generator set. Keep the load within
the nameplate rating.
Adding AC
Loads
1.
Note the rated output
of
the generator set (from the
generator set nameplate or the Specification
section).
2. Check the load rating of each
of
the items that you
plan to connect to the generator set Table 3-1 lists
typical wattages for common appliances and tools.
3. Add the wattages of the items you want to operate
and make sure that the total wattage is not more than
the generator set rated output Note the following
example.
Example:
For model 2.5
EGHAA
with a maximum
power output of
2500
wattsand a rated output of 2000
watts, it would be possible to operate a portable
heater rated at
1500
watts, a drill rated at
400
watts,
and a
100
watt light. If you also wished to operate a
circlesaw rated at
900
watts
it
would be necessary to
disconnect the heater while
you
are using the circle
Saw.
If
a motor load and another load total very close to the
rated output of the generator set, start the motor load
first and allow it to operate at normal speed before
connecting the other load. Motor loads consume
much more power during
start
up than they do when
they are running (some motors draw
up
to three times
their running load).
High
Altitudes
Maximum power decreases roughly four percent for
each 1000 feet (310 m) above sea level (after the first
1000 feet).
If
operation is degraded by altitude above
2000 feet (620
m),
calculate altitude derating to deter-
mine maximum AC load capacity.

Full Power
Switch:
Set the full power
switch to the position that corresponds to the electrical
requirements
of
your equipment (Figure
3-5).
Set the
switch to the 120V Only setting to use the 120-volt
duplex receptacle or the 120-volt twist-lock receptacle
only or to the 120/240Vsetting to use these receptacles
and the 120/240V twist-lock receptacle.
