OBTAINING ELECTRICITY FROM THE GENERATOR
There are ba si cal ly 2 ways to ob tain elec tric i ty from a gen er a tor:
1.
Use of ex ten sion cords di rect ly from the generator to the appliance, lights,
tools, etc.
2.
Use of a dou ble-throw transfer switch installed directly to the main elec tri cal
supply outside of house.
EXTENSION CORDS
When using an appliance or tool at a considerable distance from the gen er a tor, 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 ad e quate size must be used. Using the fol low ing chart to de ter-
mine the min i mum wire size re quired.

*NOTE: When am per age exceeds 20 amp; a 12 gauge extension cord should
not be used for long dis tanc es.
An extension cord that is hot to the touch is over load ed.

DOUBLE THROW TRANSFER SWITCH
Potential hazards exist when a portable electric gen er a 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 pos si ble elec tro cu tion of workers who are
repairing the elec tri cal 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 elec tri cian and in com pli-
ance with all state and local electrical codes. (When in stall ing 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 elec tri cal power outage. Your generator will
not be large enough to handle the load of all the lights, ap pli anc es, TV, etc. at one
time. To select which items to run during the electrical power outage, see Wattage
Cal cu la tion section in this manual.
