Connections for standby power to a building's electrical system must be made by a qualified
electrician. The connection must isolate the generator power from utility power, and must
comply with all applicable laws and electrical codes.
WARNING
Improper connections to a building's electrical system, can allow electrical current from the
generator to feedback into the utility lines. Such feedback may electrocute utility company
workers or others who contact the lines during a power outage. Consult the utility company or a
qualified electrician.
CAUTION
Improper connections to a building’s electrical system can allow electrical current from the
utility company to feedback into the generator. When utility power is restored, the generator
may explode, burn, or cause fires in the building’s electrical system.
2) Ground System
To prevent electrical shock from faulty appliances, the generator should be grounded. Connect
a length of heavy wire between the ground terminal and the ground source. The generators
have a system ground that connects generator frame components to the ground terminals in
the AC output receptacles. The system ground is not connected to the AC neutral wire.
If the generator is tested by a receptacle tester, it will not show the same ground circuit
condition as for a home receptacle.
3) AC Applications
Before connecting an appliance or power cord to the generator:
• Make sure that it is in good working order. Faulty appliances or power cords can create a
potential for electrical shock.
• If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off
immediately. Disconnect the appliance, and determine whether the problem is the appliance, or
if the rated load capacity of the generator has been exceeded.
• Make sure that the electrical, rating of the tool or appliance does not exceed that of the
generator. Never exceed the maximum power rating of the generator. Power levels between
rated and maximum may be used for no more than 30 minutes.
