OBTAINING ELECTRICITY FROM THE
GENERATOR
There are basically 2 ways to obtain electricity from a gen-
erator:
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.

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 deter-
mine the minimum wire size required.
An extension cord that is hot to the touch is
overloaded. Repair or replace damaged exten-
sion cords immediately.
Potential hazards exist when a portable electric genera-
tor 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 electri-
cian and in compliance 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, appli-
ances, TV, etc. at one time. To select which items to run
during the electrical power outage, see Wattage Calcu-
lation section in this manual.

6. Attach the other end of the positive (red) battery
cable to the positive (+) terminal on the battery.
7. Attach one end of the negative (black) cable to the
negative (-) terminal on the battery.
8. Attach the other end of the negative (black) cable to
the frame as shown. Install the star washer between
the cable and the frame. See Figure 6.
