Grounding the Generator
Grounding the Generator
The National Electric Code requires the generator to be
connected to an earth ground. Before using the generator,
connect a copper wire (minimum 14 AWG) from the
ground terminal (see Figure 4) to an earth ground. Con-
sult a licensed electrician for proper grounding methods.
NOTE:
The system ground is not connected to the AC neutral
wire. If using a receptacle tester, it will not show the same
ground circuit condition as for a home receptacle.
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 generator.
Please consult a qualified electrician, electrical inspector,
or the local agency having jurisdiction.
• In some areas, generators are required to be regis-
tered with local utility companies.
• If generator is used at a construction site, there may
be additional regulations which must be observed.
Using Generator for Back-up Power
The National Electric Code requires any generator con-
nected to a building’s electrical wiring utilize a transfer
switch installed by a licensed electrician.
Generator must be grounded to prevent electrical
shock from faulty appliances.
• Before using generator, consult a qualified electrician,
electrical inspector, or local agency having jurisdiction
for local codes or ordinances that apply to the intended
use of generator.

WARNING
Before connecting to a building’s electrical system, consult
your local utility company or a qualified electrician.
Improper connections to a building's electrical system can
be deadly.
Electrical current from generator can feedback into
utility lines. Such feedback may electrocute utility
company workers or others who contact utility lines
during a power outage.
Electrical current can feedback into generator. When
utility power is restored, generator may explode,
burn, or cause fires in building's electrical system.
What is a transfer switch?
A transfer switch is a device that allows switching
from utility power to emergency generator power.
The transfer switch is either a manual switch, an
automatic switch, or a combination of manual and
automatic. During a power outage, the transfer
switch isolates emergency circuits from the utility
line, allowing for efficient operation of the generator
without back-feeding into utility power.
