2.2 CORD SETS AND CONNECTION PLUGS
2.2.1 120 VAC DUPLEX RECEPTACLE
This is a 120 Volt outlet protected against overload by a 14 Amp circuit
breaker (Figure 7). 14 Amps of current may be drawn from each socket,
however, total power drawn must be kept within data plate ratings. Use
only high quality, well insulated, 3-wire grounded cord sets rated for 125
Volts at 20 Amps (or greater).
2.2.2 120/240 VAC, 20A TWISTLOCK RECEPTACLE
This is a 120/240 Volt outlet protected against overload by a 14
Amp circuit breaker (Figure 7). Connect a suitable 4-wire grounded
cord set to the plug and to the desired load. The cord set should
be rated for 250 volts at 20 amps (or greater) if the 120/240
receptacle is used along with 120 volt receptacle. The total load
drawn must not exceed the data label ratings.
IMPORTANT: Do not overload the generator. Also, do not overload
individual panel receptacles. These outlets are protected against
overload with circuit breakers. If amperage rating of any circuit
breaker is exceeded, that breaker opens and electrical output
to that receptacle is lost. Read “Don’t Overload the Generator”
carefully.

2.3 HOW TO USE THE GENERATOR
If there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.
n Never operate in an enclosed area or
indoors! NEVER use in the home, or in
partly enclosed areas such as garages,
even if doors and windows are open! ONLY
use outdoors and far from open windows,
doors, vents, and in an area that will not
accumulate deadly exhaust.
n The engine exhaust fumes contain carbon
monoxide, which can you cannot see or
smell. This poisonous gas, if breathed
in sufficient concentrations, can cause
unconsciousness or even death.
n Adequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or
permit even partial blockage of ventilation
provisions, as this can seriously affect safe
operation of the generator. The generator
MUST be operated outdoors.
n This exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
n Always use a battery operated carbon
monoxide alarm indoors, installed according
to the manufacturers instructions.
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 (Figure 8).
Local electrical codes may also require proper grounding of the
unit. For that purpose, connecting a No. 10 AWG (American Wire
Gauge) stranded copper wire to the grounding lug 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.
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.
