Don't connect your generator directly to your home's wiring.
- Connecting a portable generator directly to your household wiring can be deadly, as it can 'backfeed' onto the power lines connected to your home.
- Utility transformers can "step-up" or increase this backfeed to thousands of volts - enough to kill a utility lineman making repairs, even if he's far from your house.
- You could also cause expensive damage to utility equipment and your generator.
- The only safe way to connect a portable generator to your existing wiring is to have a licensed electrical contractor install a transfer switch.
- The transfer switch changes your power source from the utility power lines to the power that comes from your generator.
Never plug a portable 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.
- To connect a household appliance (refrigerator, lamp, etc) to the generator, always plug it directly into the receptacle outlet of the generator or extend the length with appropriately-rated outdoor extension cords.
