A generator can provide critical backup power during an outage. However, if generators are connected or used incorrectly, they can pose serious risks to you and our crews. Every year, people are seriously injured or killed in accidents involving portable generators. Before using a generator, you must consult an electrician to make sure you have the right equipment and a safe setup for your home or business.

When selecting or using a generator, keep the following top of mind:

• Portable vs. permanent generators: Even a properly connected portable generator can become overloaded or overheated, stressing the generator components, which can lead to generator failure. For power outages, permanently installed, stationary generators are better suited for providing backup power to your home or business.
• Work with an electrician: If you decide to permanently wire a generator directly to your home or business, California state law mandates that you notify SCE first by calling 1-800-655-4555. The only recommended method to connect a generator to house wiring is by hiring a licensed electrician to determine the proper setup and install a power transfer switch, in compliance with national, state and local electrical codes.
• Equipment options: Choose a generator rated for more power than you think you will need. This is best determined by an electrician.
• Setup: Do not run a portable generator indoors. Place your generator outdoors in a well-ventilated area, away from windows, doors and vents to prevent carbon monoxide buildup. Ensure there are no flammable materials or vegetation in the area and that fuels such as gasoline, propane and diesel are safely stored and handled.
• Getting connected: Use a heavy-duty, outdoor extension cord to connect electrical equipment to a portable generator. Be sure the cord is rated more than the sum of the power drawn by the connected appliances. Make sure the cord has no cuts or tears, and that the plug has all three prongs. Do not connect a portable generator to your home's electrical wiring or electrical panel. This can lead to serious injury or electrocution.
• Safety hazards: Be sure to follow the safety directions supplied with your generator to avoid hazards like carbon monoxide (CO) poisoning, electric shock, electrocution and fire. Don’t run cords under carpet, rugs or furniture. Heat could build up or the cords could be damaged without you knowing, creating a fire or electrocution hazard.
• Beware of backfeed: Never try to power your home by plugging a generator into a wall outlet or temporarily wiring into the electrical panel. This can create backfeed, which is extremely dangerous and can lead to electrocution of you, your neighbors or utility workers who may be working on nearby power lines.
