Always:

• Use qualified electrician to install a stationary or stand-by emergency generator
• Install a special safety transfer switch, required by the National Electric Code. The switch prevents the generator from back-feeding electricity onto the power lines which could be deadly to unsuspecting workers.
• 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, and always follow state, local, and national fire and electric codes.
• Turn off all equipment powered by the generator before shutting down your generator.
• Keep children and pets away from portable electric generators at all times.
• Always operate generators outdoors to avoid the buildup of deadly carbon monoxide fumes. 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, and ensure you have protected it from direct exposure to rain and snow, preferably under a canopy, open shed or carport.

And never:

• Connect the generator to your home's main electrical panel. Again, you could be putting your life and that of your family and our workers in jeopardy.
• 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.
• 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, so you must prioritize your needs. A portable electric generator should also be used only when necessary, and only to power essential equipment.
