Connecting the Generator to a
Building Electrical System
It is recommended to use a manual transfer
switch when connecting directly to a building
electrical system to prevent hazardous back-
feeding and avoid injuring utility line workers.
When connecting a portable generator to a
building electrical system, a transfer switch
must isolate the generator power from the util-
ity power at all times. Failure to comply will
result in a hazardous condition. Installation is
to be made in strict compliance with all
national and local electrical codes and laws,
and be completed by a qualified electrician.

Special Requirements

Review all Federal or State Occupational
Safety and Health Administration (OSHA) reg-
ulations, local codes, or ordinances that apply
to the intended use of the generator.
Consult a qualified electrician, electrical
inspector, or the local agency having jurisdic-
tion:
• 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.

Know Generator Limits

Overloading a generator can result in damage
to the generator and connected electrical
devices. Observe the following to prevent
overload:
• Add the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the gener-
ator's wattage capacity.
• The rated wattage of lights can be taken
from light bulbs. The rated wattage of tools,
appliances, and motors can 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 approximately 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 con-
nect to the generator:
1. Calculate 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 gen-
erator can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.
