Powering up for safety
Make sure a generator is rated for more than the amount of power that you think you will need. Look at the labels on lighting, appliances, and equipment you plan to connect to the generator to determine the amount of power that will be needed. This is best determined by an electrician.
Using a generator
The primary hazards to avoid when using a generator are carbon monoxide (CO) poisoning from the toxic engine exhaust, electric shock, electrocution and fire. Follow the directions supplied with the generator. Every year, people die in incidents related to portable generator use.
Plug appliances directly into the generator or use a heavy duty, outdoor-rated extension cord that is rated more than the sum of the connected appliance loads. Make sure that the entire cord has no cuts or tears and that the plug has all three prongs, especially a grounding pin.
Beware of "Backfeeding"
Never try to power the house wiring by plugging a generator into a wall outlet, otherwise known as "backfeeding". This is extremely dangerous and can electrocute utility workers and even neighbors. Electrocution is the fifth leading cause of all reported occupational deaths.
A better solution
The only recommended method to connect a generator to house wiring is by having a qualified electrician install a power transfer switch. This switch must be installed in accordance with the National Electrical Code® (NEC), which is published by the National Fire Protection Association, and all applicable state and local electrical codes. Call a qualified electrician or check with your utility company to see if they can install the appropriate equipment.
For power outages, permanently installed stationary generators are better suited for providing backup power to a home or business. Even a properly connected portable generator can become overloaded. This may result in overheating or stressing the generator components, possibly leading to a generator failure. Be sure to read instructions that come with the generator to make sure you operate it within its limitations for power output.
Safe Portable Generator Hook up
Connecting a portable generator to your home’s electrical wiring is dangerous and can cause serious injuries or electrocution. Do not hook up a generator directly into an electrical panel. The safe way is to connect the electrical equipment to a portable generator using a properly sized extension cord.
If your needs require a generator to be wired directly to your home, California state law mandates that you notify SCE. We also recommend that you enlist the service of a qualified electrician to perform the task.
