4.4 Grounding Method
4.4.1 Ground Terminal
The generator ground terminal(1) is connected to the frame of
the generator, metal non-current-carrying generator parts and
the ground terminals of each receptacle.
4.4.2 Connections 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,
and must comply with all applicable laws and electrical codes.
Improper connections to a building’s electrical system can allow electrical current from the
generator to backfeed into the utility lines. Such backfeed may electrocute utility company
workers or others who contact the lines during a power outage. Consult the utility company
or a qualified electrician.
Improper connections to a building’s electrical system can allow electrical current from the
utility company to backfeed into the generator. When utility power is restored, the generator
may explode, burn, or cause a fire in the building’s electrical system.
4.4.3 Ground System
AIRMAN’s generators have a system ground that connects generator frame components to the
ground terminals in the AC output receptacles. The AC neutral wire is connected to the
system ground.
