WARNING
Have standby installation performed by a skilled,
licensed electrician. Do not let anyone else wire into
a utility circuit. Personal injury, equipment damage,
or damage to home could occur.
IMPORTANT:
This generator will not power your entire home. Most home utility
electric service is more than 60 amps. This will exceed generator output. Only
power needed items during a power outage. Make sure total wattage of electrical
load does not exceed rated wattage of generator.
You can use this generator as a standby power source. During a power outage, the
generator will power selected items in a building. Have generator and additional
wiring installed by a skilled, licensed electrician. This is not a do-it-yourself job.
Follow all local codes.
WARNING
The electrician must install a double-throw transfer
switch. This isolates existing electrical circuits from
the utility power line. If not isolated, generator output
will back-feed into utility power line. This may
electrocute a power company line repair person.
