System Ground
The generator has a system ground that connects the
generator frame components to the ground terminals on the
AC output receptacles. The system ground is connected to
the AC neutral wire (the neutral is bonded to the generator
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 generator.
Please 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 a Building’s Electrical System
Connections for standby power to a building’s electrical
system must be made by a qualified electrician. The
connection must isolate the generator power from utility
power or other alternative power sources and must comply
with all applicable laws and electrical codes.
Generator Location
Clearances and Air Movement

away from any windows, doors, ventilation intakes, or other
openings that can allow exhaust gas to collect in a confined
area. Prevailing winds and air currents should be taken into
consideration when positioning generator.
