coRD SETs AND CONNECTOR PLUGS
120 VOLTS DUPLEX RECEPTACLE
Use only high quality, welt-insulated, extension cords with
the 120-volt "duplex" type electrical receptacles. All cord
sets used should be rated 125 volts at 20 AC amps or
greater for most electrical devices Keep extension cords
as short as possible, preferably less than 15 feet tong to
prevent voltage drop and wires from overheating.
120 VOLTS, 20 AND 30 AMP RECEPTACLES:
o For the 120 volts, 20 amp locking type NEMA L5-20R
receptacle, a well-insulated cord set with a NEMA
L5-20P locking type connector plug must be properly
connected to the recept&cle and to the desired 120
volts, single phase, 60 Hz, AC load. Cord sets should
be rated 20 AC amperes at 125 volts (or greater) for
most electrical devices (Fig. 3).

o For 120 volts, 30 amp locking type NEMA L5-30R
receptacle, a welHnsulated cord set with a NEMA
L5-30P locking type connector plug must be properly
connected to the receptacle and the desired 120 volts,
single phase, 60 Hz, AC load The cord set should be
rated 30 AC amperes at 125 volts (or greater) for most
electrical devices (Fig. 3).
120/240 VOLTS, 30 AMP RECEPTACLE:
A 120/240 volts, 30 amp, locking type type mating connec-
tor plug (Fig 4) is required when using this receptacle A
4-wire cord set, rated 30 AC amperes at 250 volts (or
greater), is required and must be connected to the plug and
to the desired loads Order NEMA type L14-30P
240 VOLTS, 50 AMP RECEPTACLE (Fig. 5)
This receptacle is rated 50 AC amperes at 250 volts. You
need a 3-prong grounded connector plug with same rating
to use with this outlet. Although current capacity of outlet
is rated at 50 amps, loads applied through this outlet should
not exceed 33.3 amps or you will overload the generator
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
FIG. 5
uniL For that purpose, a GROUNDING WING SCREW is
)rovided on the base of the cradle (Fig. 6).
FIG. 6
Generally, connecting a No. 12 AWG (American Wire
Gauge) stranded copper wire to the grounding screw and
to an earth-driven copper or brass grounding rod (elec-
trode) provides adequate protection against electrical
shock. However, local codes may vary widely. Consult with
a local electrician for grounding requirements in your are&
Proper grounding of generator will help prevent electrical
shock in the event of a ground fault condition in the gener-
ator or in connected electrical devices Proper grounding
also helps dissipate static electricity, which often builds up
in ungrounded devices
