Operation
DANGER
Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide. This is
a poison you cannot see or smell.
NEVER use inside a home
or garage, EVEN IF doors
and windows are open.
Grounding Generator If Used as Portable
An equipment ground connects the generator frame com-
ponents to ground terminals on the AC output recepta-
cles. This allows the generator to be used as a portable
without grounding the frame as specified in NEC 250.34.
Neutral bonded to frame.
Special Requirements
There may be Federal or State Occupational Safety and
Health Administration (OSHA) regulations, local codes,
or ordinances that apply to the intended use of the gener-
ator.
Consult a qualified electrician, electrical inspector, or the
local agency having jurisdiction:
•
In some areas, generators are required to be registered
with local utility companies.
•
If the generator is used at a construction site, there may be
additional regulations which must be observed.
Connecting to Building Electrical System
Use a manual transfer switch when connecting directly to
a building electrical system. Installation and connections
must be performed by a qualified electrician and in strict
compliance with all national and local electrical codes
and laws.
12
Only use OUTSIDE and
far away from windows,
doors, and vents.

Know Generator Limits

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 rules
to avoid overloading:
•
Add up the total wattage of all electrical devices to be con-
nected at one time. The total should NOT be greater than
the wattage capacity of the generator.
•
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, multi-
ply 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 power surge lasts only a few seconds. To
allow for high starting wattage when selecting electrical
devices to connect to the generator, proceed as follows:
Figure the watts needed to start the largest motor.

Add to that figure the running watts of all other connected
