Using a properly connected generator of adequate size during a power outage will reduce or almost eliminate the impact a power outage has on your life. Before you buy a generator, talk to an electrician about the size and type you need. Think about what you want your generator to run. Generators can be used to keep food cool, provide lights and electricity for phones and television, power furnace blowers and pumps.

The best way to use a portable generator is to connect it to your home using a transfer switch installed by a licensed electrician. This will keep the power from overloading the wiring in your home. It will also keep the power from your generator from traveling back into the power lines, which can injure or kill people working on power lines, or can unexpectedly re-energize downed power lines near your home. You may also connect equipment directly to the outlets on the generator, but be sure that any extension cords are of the proper length and gauge to handle the power requirements.

Remember: Always run generators outside. Never use a generator inside a house, in a basement, or garage. Never use a cord from a generator to backfeed a circuit in your house.
