2.3.6 120/240 VAC, 50 AMP RECEPTACLE

Use a NEMA 14-50 plug with this receptacle. Connect a 4-wire cord set
rated for 250 Volts AC at 50 Amps to the plug (Figure 14).
Figure 14 - 120/240 VAC, 50 Amp Receptacle
Use this receptacle to operate 120/240 Volt AC, 60 Hz electrical loads
requiring up to 12,000 watts (12.0 kW) of power. This receptacle is
protected by a 50 Amp 2-pole circuit breaker.

HOW TO USE THE GENERATOR

If there are any problems operating the generator, please call the generator
helpline at 1-888-436-3722.

2.4.1 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 (Figure 15). 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 the area.
Floating AC neutral wires of receptacles are not bonded to system
ground.

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.
2.4.2 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.
2.5

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 label 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
to allow for high starting wattage when selecting electrical devices to
connect to the 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 is provided to assist in determining how
many items the generator can operate at one time.
