2.3- DON'T OVERLOAD THE GENERATOR (Table 2-2)
DO NOT exceed the generator's rated WATTAGE and/or AMPERAGE capacity
for continuous operation. Before connecting electrical loads to panel
receptacles, add up the WATTS (or the AMPERES) required to operate
those loads. Rated watts and/or amperage can usually be found on the
nameplate of lights, appliances, motors, etc. The total of all loads
being powered at one time should not exceed 2400 watts or 20.0 a-c
amperes.
NOTE
Some electric motors (such as saws, drills, etc.) require more watts
of power or amperes of current than is stated on their nameplate, when
the motor is being put to hard use. For example, a saw that is used to
cut through extremely difficult material may require 3 to 4 times more
wattage or amperage than is stated on its nameplate.
Some electric motors (such as Universal, Repulsion-Induction,
Capacitor, or Split Phase type) require more amperes of current for
starting than for continuous on-speed operation. Approximate starting
and running current (in amperes) is listed in Table 2-2. To use the
chart, find the TYPE OF MOTOR and its RATED HORSEPOWER on the motor
nameplate. Then, locate the approximate starting and running amperes
in the chart.

2.4- STARTING THE ENGINE (Figure 2-2)
a. Disconnect Electrical Loads:- Disconnect or turn OFF all electrical
loads connected to generator receptacles.
CAUTION!
Never start or stop the engine with electrical loads connected and
turned on. The generator will supply its rated voltage and frequency
only at its correct rated operating speed. Some electrical devices may
be damaged by incorrect voltage and/or frequency. In addition, start-
ing the engine with electrical loads applied imposes a heavy load at
lower operating speeds where adequate power is not yet available and
may shorten engine lifeo
