1. When amperage exceeds 20 amp; a 12 gauge extension
cord should not be used for long distances.
2. When amperage exceeds 30 amp; a 10 gauge extension
cord should not be used for long distances.
Extension Cords
When using an appliance or tool at a considerable distance
from the generator, a 3-wire extension cord that has a 3-
blade grounding plug and a 3-slot receptacle that accepts
the tool's plug MUST be used in order to reduce the risk of
electrical shock. A cord of adequate size must be used.
Using the following chart to determine the minimum wire size
required.
An extension cord that is
hot to the touch is over-
loaded. Repair or replace damaged extension
cords immediately.
Double Throw Transfer Switch
Potential hazards exist
when a portable electric
generator is connected to the main electrical
supply coming into the house. It is at that point
that the electrical generator could feed back into
the utility company's system causing possible
electrocution of workers who are repairing the
electrical lines.
To avoid back feeding of electricity into utility
systems, a double-throw transfer switch must be
installed between the generator and utility power.
The Double-Throw Transfer Switch should be
installed by a licensed electrician and in compli-
ance with all state and local electrical codes.
(When installing a Double-Throw Transfer Switch,
a minimum of 10 gauge wiring must be used.)
The electrician should also install a sub-panel to
isolate the circuits you would want to use during
an emergency or electrical power outage. Your
generator will not be large enough to handle the
load of all the lights, appliances, TV, etc. at one
time. To select which items to run during the
electrical power outage, see Wattage Calculation
section in this manual.
OBTAINING ELECTRICITY FROM THE
GENERATOR
There are basically 2 ways to obtain electricity from a gener-
ator:
1. Use of extension cords directly from the generator to the
appliance, lights, tools, etc.
2. Use of a double-throw transfer switch installed directly to
the main electrical supply outside of house.
OTHER LOOSE PARTS
1. Oil is supplied, see engine operator’s manual for correct
procedure to add oil and fuel to engine.
2. The locking plugs maybe used when needed or
required.
The locking plugs are to
be installed and/or used in
accordance with appropriate local electrical
code regulations. Refer to instructions enclosed
with each plug for proper installation.
3. 12V DC cables to be used with the 12V DC outlets. See
Operation section.
GROUNDING THE GENERATOR
A grounding lug is supplied with
the generator for use when
required by local electrical
ordinances. Refer to article 250
of the National Electrical Code to
clarify any needed grounding
information. Your local electric
company or a certified electrician
should be able to help you with
this information.
NOTE: Your engine is already grounded to the frame by a
grounding strap.
Grounding Lug
IMPORTANT: Before any attempt to start your generator be
sure to check engine oil (See Engine Operator's manual)
