Portable
Electric Generator Safety Tips
|
Portable electric generators offer great benefits
when outages affect your home. Below are guidelines for
safely connecting and operating portable
generators.
Don't connect your generator directly to your
home's wiring.
Connecting a portable electric generator directly to
your household wiring can be deadly to you and others. A
generator that is directly connected to your home's
wiring can 'backfeed' onto the power lines connected to
your home.

Utility transformers can then
"step-up" or increase this backfeed to thousands of
volts—enough to kill a utility lineman making outage repairs a
long way from your house. You could also cause expensive damage
to utility equipment and your generator.
The only safe way to connect a portable
electric generator to your existing wiring is to have a licensed
electrical contractor install a transfer switch. The transfer
switch transfers power from the utility power lines to the power
coming from your generator.
Never plug a portable electric generator
into a regular household outlet.
Plugging a generator into a regular household outlet can
energize "dead" power lines and injure neighbors or
utility workers. Connect individual appliances that have their
outdoor-rated power cords directly to the receptacle outlet of
the generator, or connect these cord-connected appliances to the
generator with the appropriate outdoor-rated power cord having a
sufficient wire gauge to handle the electrical load.
Don't overload the generator.
Do not operate more appliances and equipment than the output
rating of the generator. Overloading your generator can
seriously damage your valuable appliances and electronics.
Prioritize your needs. A portable electric generator should be
used only when necessary, and only to power essential equipment.
Never use a generator indoors or in an
attached garage.
Just like your automobile, a portable generator uses an internal
combustion engine that emits deadly carbon monoxide. Be sure to
place the generator where exhaust fumes will not enter the
house. Only operate it outdoors in a well-ventilated, dry area,
away from air intakes to the home, and protected from direct
exposure to rain and snow, preferably under a canopy, open shed
or carport.
Use the proper power cords.
Plug individual appliances into the generator using heavy-duty,
outdoor-rated cords with a wire gauge adequate for the appliance
load. Overloaded cords can cause fires or equipment damage.
Don't use extension cords with exposed wires or worn shielding.
Make sure the cords from the generator don't present a tripping
hazard. Don't run cords under rugs where heat might build up or
cord damage may go unnoticed.
Read and adhere to the manufacturer's
instructions for safe operation.
Don't cut corners when it comes to safety. Carefully read and
observe all instructions in your portable electric generator's
owner manual.
To prevent electrical shock, make sure
your generator is properly grounded.
Consult your manufacturer's manual for correct grounding
procedures.
Do not store fuel indoors or try to
refuel a generator while it's running.
Gasoline (and other flammable liquids) should be stored outside
of living areas in properly labeled, non-glass safety
containers. They should not be stored in a garage if a
fuel-burning appliance is in the garage. The vapor from gasoline
can travel invisibly along the ground and be ignited by pilot
lights or electric arcs caused by turning on the lights. Avoid
spilling fuel on hot components. Put out all flames or
cigarettes when handling gasoline. Always have a fully charged,
approved fire extinguisher located near the generator. Never
attempt to refuel a portable generator while it's running.
Turn off all equipment powered by the
generator before shutting down your generator.
Avoid getting burned.
Many generator parts are hot enough to burn you during
operation.
Keep children away from portable electric
generators at all times. |
