NOTE:
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.

Using Generator for Back-up Power
DANGER
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
