Portable Generator Safety

Portable generators are not intended to replace your home’s energy source. They should be used sparingly for powering a few appliances when power is not available. Don't cut corners when it comes to safety. Carefully read and follow all instructions in your portable electric generator's owner manual. Learn more about portable generator safety from the Electrical Safety Foundation. 

Don’t Connect Your Generator Directly to Existing Wiring

Attempting to connect a portable electric generator directly to existing wiring in your home or business can be deadly to you and others. This can “backfeed” onto the power lines coming from the electrical grid which can kill lineworkers making outage repairs.

The only safe way to connect a portable electric generator to existing wiring is to install a transfer switch. The transfer switch transfers power from the utility power lines to the power coming from your generator. Installation of transfer switches requires an electrical permit obtained by a Registered Licensed Electrical Contractor.

Note: Not all transfer switches are approved by Austin Energy. Find a list of approved transfer switches and permitting information on our Socket-Mounted Transfer Switch Devices page.

Never Use a Generator Indoors

Never run a generator inside your home or partially enclosed spaces including garages, crawl spaces, or even areas with partial ventilation. Generators release odorless carbon monoxide and need to be placed in a dry, outside location at least 20 feet from doors, windows, and vents. Take extra precautions by installing carbon monoxide alarms in your home to avoid the buildup of toxic fumes.

Use the Proper Power Cords

Plug individual appliances into the generator using heavy-duty, outdoor-rated cords with a wire gauge suitable for the intended load to meet your power needs. Overloaded cords can cause fires or equipment damage. Don't use cords with exposed wires or worn shielding. Keep cords out of the way to avoid tripping hazards. Never run cords under rugs where heat might build up or cord damage may go unnoticed.

Use Proper Grounding

To prevent electrical shock, make sure your generator is properly grounded. Consult your manufacturer's manual for correct grounding procedures.

Do Not Store Fuel Indoors or Refuel a Generator While It's Running

Gasoline (and other flammable liquids) should be stored outside of living and working areas in properly labeled, non-glass, safety containers. They should not be stored near other fuel-burning appliances, such as water heaters. Avoid spilling fuel on hot components. Always have a fully charged, approved fire extinguisher located near the generator. Never attempt to refuel a portable generator while it's running.

Shut the Generator Down Properly

Turn off all equipment powered by the generator before shutting down your generator.

Avoid Getting Burned

Many generator parts are hot enough to burn you during operation.

Keep Children Away

Children are naturally curious. Always keep them away from generators to avoid injury.
