2.3 HOW TO USE THE GENERATOR
If you have any problems operating your generator, please call the
generator helpline at 1-800-333-1322.
2.3.1 GROUNDING THE GENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local electrical
codes may also require proper grounding of the unit. For that
purpose, generally, connecting a No. 10 AWG (American Wire
Gauge) stranded copper wire to the grounding wing nut and to an
earth-driven copper or brass grounding rod (electrode) provides
adequate protection against electrical shock. However, local
codes may vary widely. Consult with a local electrician for
grounding requirements in your area.
Figure 13 - Grounding the Generator
Proper grounding of the generator will help prevent electrical
shock in the event of a ground fault condition in the generator or
in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in ungrounded
devices.
2.3.2 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
• Let engine stabilize and warm up for a few minutes after
starting.
• Plug in and turn on the desired 120 or 240 Volt AC, single
phase, 60 Hz electrical loads.
• Add up the rated watts (or amps) of all loads to be connected
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breaker rating of the receptacle supplying the power. See
"Don't Overload the Generator" below.
2.4 DON’T OVERLOAD THE
GENERATOR
Overloading a generator in excess of its rated wattage capacity
can result in damage to the generator and to connected electrical
devices. Observe the following to prevent overloading the unit:
• Add up the total wattage of all electrical devices to be
connected at one time. This total should NOT be greater than
the generator's wattage capacity.
• The rated wattage of lights can be taken from light bulbs. The
rated wattage of tools, appliances and motors can usually be
found on a data plate or decal affixed to the device.
• If the appliance, tool or motor does not give wattage, multiply
volts times ampere rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction types, require about
three times more watts of power for starting than for running.
This surge of power lasts only a few seconds when starting
such motors. Make sure you allow for this high starting
wattage when selecting electrical devices to connect to your
generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected
loads.
The Wattage Reference Guide on page 10 is provided to assist you
in determining how many items your generator can operate at one
time. (Note: All figures are approximate. See data plate on
appliance for wattage requirements.)
