Grounding the Generator
Grounding the Generator
The National Electric Code (NEC) requires the generator
to be connected to an earth ground. Before using the gen-
erator, connect a copper wire (minimum 10 AWG) from the
ground terminal (see Figure 17) to an earth ground. Con-
sult a licensed electrician for proper grounding methods.
The generator is neutral floating which means the ground
terminal on the generator is not connected to the AC neu-
tral wire in the generator. 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.
Consult a licensed 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 Backup Power
Generator must be grounded to prevent electrical
shock from faulty appliances.
• Before using generator, consult a licensed electrician,
electrical inspector, or local agency having jurisdiction
for local codes or ordinances that apply to the intended
use of generator.
FIGURE 17: Ground Terminal
Improper connections of the generator to a building’s electri-
cal 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.
• Before connecting to a building’s electrical system, con-
sult a licensed electrician, electrical inspector, or local
agency having jurisdiction for local codes or ordinances
that apply to the intended use of generator.
