1.2 AC SAFETY
WARNING!
Before connecting the generator to an electrical device or power cord:
Make sure that everything is in proper working order. Faulty devices or
power cords can lead to an electrical shock.
Turn off the generator immediately if the device begins to operate
abnormally. Then disconnect the device and investigate the problem.
Make sure that the electrical rating of the device does not exceed
that of the generator. If the power level of the device is between the
maximum output power and the running power of the generator, the
generator should not be used for more than 30 minutes.
Connections for standby power to a building's electrical system must
be done by a qualified electrician and must comply with all applicable
laws and electrical codes. Improper connections may cause serious
injuries to electrical workers during a power outage, and when the
utility power is restored, the generator may explode or cause fires. The
generator shall be connected through transfer equipment that switches
all conductors other than the equipment grounding conductor. The
frame of the generator shall be connected to an approved grounding
electrode.
For power outages, permanently installed stationary generators are
better suited for providing backup power to the home. Even a properly
connected portable generator can become overloaded. This may result
in overheating or stressing the generator components, possibly leading
to a generator failure.
