Operation
Connecting to a Building’s Electrical System through a 
Transfer Switch
IMPORTANT:  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.
NOTE: This generator system ground IS bonded to the neutral in 
the generator (see applicable unit wiring diagram).
2.6.2  GROUNDING THE GENERATOR
Local electrical codes may 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.

2.6.3  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".
2.7  OVERLOAD PREVENTION
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.
• If the appliance, tool or motor does not give wattage, multiply 
volts times ampere rating to determine watts (volts x amps = 
watts).
• Some electric motors, such as induction types, require about 
three times more watts of power for starting than for running. 
This surge of power  lasts  only  a  few  seconds  when starting 
such motors. Make sure to allow for high starting wattage when 
selecting electrical devices to connect to the generator:
1.  Figure the watts needed to start the largest motor.
2.  Add  to  that  figure  the  running  watts  of  all  other  connected 
loads.
The Wattage Reference Guide is provided to assist in determining 
how many items the generator can operate at one time.
NOTE: All figures are approximate. See data label on appliance 
for wattage requirements.
