2.4.1 GROUNDING THEGENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connectedto an approvedearth ground (Figure 8).
Local electrical codes may also require proper grounding of the
unit. Forthat purpose, connecting a No. 10 AWG (AmericanWire
Gauge) stranded copper wire to the grounding lug and to an
earth-driven copper or brass grounding rod (electrode) provides
adequateprotectionagainst electricalshock. However,local codes
may vary widely. Consultwith a local electricianfor grounding
requirements in the area.

LUG
Proper groundingof the generatorwill help preventelectrical
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.
2.4.2 CONNECTING ELECTR/CAL L OADS
DO NOTconnect 240 Volt loadsto 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 AO, single
phase, 60 Hz electrical loads.
• Add up the ratedwatts (or amps) of all loadsto be connected
at one time. This total should not be greaterthan (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breakerratingof the receptaclesupplying the power.See "Don't
Overloadthe Generator".
2.5 DON'T OVERLOAD THEGENERATOR
Overloadinga generator in excess of its rated wattage capacity
can result in damageto the generatorand to connectedelectrical
devices. Observethe following to preventoverloadingthe unit:
• Add up the total wattageof all electricaldevicesto be connected
at one time. This total should NOT be greater than the
generator'swattage capacity.
• The ratedwattage 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 affixedto the device.
• If the appliance,tool or motor does not give wattage, multiply
volts times ampererating to determinewatts (volts x amps =
watts).
• Some electric motors, such as induction types, require about
threetimes more watts of power for starting than for running.
This surge of power lasts only a few seconds when starting
such motors. Make sureto allowfor high startingwattagewhen
selectingelectrical devicesto connect to the generator:
1. Figurethe watts neededto start the largest motor.
2. Add to that figure the running watts of all other connected
loads.
The WattageReferenceGuide is providedto assist in determining
how many items the generatorcan operateat one time.
NOTE:
All figures are approximate. See data label on appliance for
wattage requirements.
