2.3 CORD SETS AND CONNECTION PLUGS

2.3.1 120 VAC, 20 AMP, DUPLEX RECEPTACLE
This is a 120 Volt outlet protected against overload by a 20 Amp
push-to-reset circuit breaker (Figure 6). Use each socket to power
120 Volt AC, single phase, 60 Hz electrical loads requiring up to a
combined 2400 watts (2.4 kW) or 20 Amps of current. Use only
high quality, well-insulated, 3-wire grounded cord sets rated for
125 Volts at 20 Amps (or greater).
Keep extension cords as short as possible, preferably less than
15 feet long, to prevent voltage drop and possible overheating of
wires.
Figure 6 - 120 Volt AC, 20 Amp, Duplex Receptacle
2.3.2 120/240 VAC, 30 AMP RECEPTACLE
Use a NEMA L14-30 plug with this receptacle (rotate to lock/
unlock). 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
AC at 30 Amps (or greater) (Figure 7).
Figure 7 - 120/240 VAC, 30 Amp Receptacle
Use this receptacle to operate 120 Volt AC, 60 Hz, single phase
loads requiring up to 3600 watts (3.6 kW) of power at 30 Amps
or 240 Volt AC, 60 Hz, single phase loads requiring up to 7200
watts (7.2 kW) of power at 30 Amps. The outlet is protected by
two 25 Amp (5.0/5.5kW) or two 30 Amp (6.5kW) push-to-reset
circuit breakers.

2.4 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 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.
Figure 8 - 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.

2.4.2 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".
