Generator Use - Honda EU20i Owner's Manual

Be sure to ground the generator when the connected equipment is
grounded.
Do not connect to a building's electrical system unless an isolation
switch has been installed by a qualified electrician.
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 back feed into the
utility lines. Such back feed 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.
