USING RECEPTACLE
Note:
Do not exceed amperage rating of
receptacles. Exceeding rating will trip re-
ceptacle circuit breaker.
Use receptacles properly. Improper use could
damage generator. Use only grounded exten-
sion cords. Power only grounded or double-
insulated items. Do not overload receptacles.
All generators (except models HWI3000,
MGH3000G, MGH3000, and MGH3000PR)
have the following receptacles (see Figure 17):
• 120V, 15-amp GFCI duplex receptacle
• 120V, 30-amp twist-lock receptacle
• 120/240V, 20 or 30-amp twist-lock
receptacle
• 120V, 15-amp duplex receptacle
Model MGH10000A also has a 120/240V,
50-amp receptacle (see Figure 17).
Model HWI3000 has only the 120V, 20-
amp duplex receptacle.
Models MGH3000G, MGH3000 and
MGH3000PR have only the 120V, 15-amp
GFCI duplex receptacle.
DANGER: Never connect gen-
erator to any existing electrical
circuits. The generator output will
back-feed into the utility power
line. This may electrocute a power
company line repair person. Also,
if generator is powering electri-
cal circuits, the chance of an elec-
trical fire exists.
DANGER: Use only in well-
vented areas. Make sure area has
plenty of free-moving, fresh, out-
side air. Never run generator in
an enclosed or confined area.
Never run generator inside occu-
pied building. Engine exhaust
contains poisonous carbon mon-
oxide gas. Overexposure will
cause loss of consciousness and
will lead to death.
