Generator Safety: Essential Tips for Safe Usage and Installation

Standby generators can provide reliable power, but safety must always come first.

Standby generators are a valuable backup power source, especially during outages, but improper use can create serious risks, including electrical shock and fire hazards. Whether you’re using a portable or permanently installed generator, understanding the safety requirements is essential.

Buying a Standby Generator

• Ensure the generator and its components are certified by a recognized certification agency. Check for the certification mark to verify safety compliance.
• Understand your electricity requirements to choose the correct generator size and voltage for your needs.
• Purchase appropriate accessories, such as an approved transfer switch, properly sized connector cords, and plugs.

Using Your Generator Safely

• Do not operate a generator indoors: Never run a generator inside your home or garage to avoid a dangerous buildup of carbon monoxide fumes. Open windows and doors or fans are not sufficient to keep your home safe.
• Avoid water-damaged appliances: Never connect portable generators to electrical appliances or wiring that has been affected by water.
• Use proper extension cords: Ensure extension cords are grounded, have three prongs, and are rated for your specific usage. Always uncoil cords completely to prevent overheating.
• Handle gasoline safely: Gasoline and its vapors are extremely flammable. Allow the generator engine to cool for at least 2 minutes before refueling and always use fresh gasoline.

Permanent Generator Installations

If you’re installing a standby generator permanently, it must be connected to your home’s electrical wiring using a transfer device. This prevents generator power from flowing back into the utility system, protecting your home and utility workers. You must file a notification of work with the Electrical Safety Authority (ESA) before connecting a generator permanently to your electrical system.

ESA strongly recommends hiring a Licensed Electrical Contractor to ensure the generator is correctly installed. You can find a Licensed Electrical Contractor using ESA’s lookup tool:
