Generator Use - Honda EU26i Owner's Manual

GENERATOR USE

Be sure to ground the generator when the connected equipment is
grounded.
Connections for standby power to a building's electrical system must
be made by a qualified electrician and must comply with all applicable
laws and electrical codes. Improper connections 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, and when utility power is
restored, the generator may explode, burn, or cause fires in the
building's electrical system.
