GENERATOR USE
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.
Import 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 fires in the building
’
s electrical system.
In some areas, generators are required by law to be registered with local utility
companies. Check local regulations for proper registration and use procedures.
Generator Ground Circuits
GENEX portable generators have a system ground that connects generator frame
components to the ground terminals in the AC output receptacles. The system
ground is not connected to the AC neutral wire.
Local regulations, codes or laws may require that the ground system be
connected to the AC neutral wire. If the generator is tested by a receptacle tester,
it will not show the same ground circuit condition as for a home receptacle.
If local regulations, codes, or laws require the system ground to be connected to
the AC neutral wire, consult a qualified electrician or electrical inspector. Provide
him with the electrical wiring diagram in this manual.
The ground terminal can be used to earth generator or bond the frame of the
generator to the frame of a vehicle, but only if it is required by local law or
electrical code. Before using the ground terminal consult a qualified electrician or
electrical inspector for regulations in your area.
