• In some areas, generators are required to be registered with
local utility companies.
• If the generator is used at a construction site, there may be
additional regulations which must be observed.
Connecting to a Building's Electrical System
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 or other alternative
power sources and must comply with all related laws and codes.
2.4.2 GROUNDING THE GENERATOR
The National Electrical Code requires that the
frame and external electrically conductive parts
of this generator be properly connected to an
approved earth ground (Figure 6).
Local electrical codes may also require proper grounding of the
unit. For that purpose, connecting a No. 10 AWG (American Wire
Gauge) stranded copper wire to the grounding lug and to an
earth-driven copper or brass grounding rod (electrode) provides
adequate protection against electrical shock. However, local codes
may vary widely. Consult with a local electrician for grounding
requirements in the area.

Proper grounding of the generator will help
prevent electrical shock in the event of a
ground fault condition in the generator or in
connected electrical devices. Proper grounding
also helps dissipate static electricity, which
often builds up in ungrounded devices.
2.4.3 NEUTRAL TO FRAME GROUNDING
If service work is performed on the alternator, DO NOT discard
the white jumper wires from the terminal block to the alternator
ground, located on the rear bearing carrier. Alway make sure the
wires are properly connected before using the generator after
alternator service work is done (Figure 7).

Failure to reconnect these wires may create a
potential shock hazard when the generator is
running!
2.4.4 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
• Let engine stabilize and warm up for a few minutes after
starting.
• Plug in and turn on the desired 120 or 240 Volt AC, single
phase, 60 Hz electrical loads.
• Add up the rated watts (or amps) of all loads to be connected
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breaker rating of the receptacle supplying the power. See "Don't
Overload the Generator".
2.5 DON'T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage capacity
can result in damage to the generator and to connected electrical
devices. Observe the following to prevent overloading the unit:
• Add up the total wattage of all electrical devices to be connected
at one time. This total should NOT be greater than the
generator's wattage capacity.
• The rated wattage of lights can be taken from light bulbs. The
rated wattage of tools, appliances and motors can usually be
found on a data label or decal affixed to the device.
