The Big Picture

  From SafeElectricity.org

When power goes out, it’s handy to have a generator. However, using a generator should not be taken lightly. It can be dangerous or even life-threatening if used incorrectly.

Before purchasing a generator, the first step is to research the best option for your home and budget. The second, and more important, step is to educate yourself on how to use one safely.

You can choose from two types of generators: standby and portable. Standby generators are installed directly into the home’s electrical system and are typically powered by natural gas or propane. These generators start automatically when the power goes out.

A portable generator is usually gas powered. Your generator should have more output than the wattage of the electronics plugged into it. Make sure there is nothing plugged into the generator when turning it on.

Safety Tips

When you refuel a portable generator, make sure the engine is cool. Keep children and pets away from the generator, as it could burn them.

Generators pose electrical risks, especially when operated during inclement weather. Use a generator only when necessary during wet conditions. Protect the generator by operating it under an open, canopy-like structure and on a dry surface where water cannot form puddles or drain under it.

Generators can be deadly

Carbon monoxide emitted by the gasoline engine on the generator can be deadly. Always operate your portable generator outdoors at least 20 feet from your home.

Misusing a portable generator or using a standby generator that is installed incorrectly can cause backfeed. Backfeed happens when a generator feeds electricity back through a home’s electrical system and meter into the power lines. To prevent this dangerous scenario, standby generators should have a transfer switch installed by a licensed professional.

Do not plug a portable generator directly into a home outlet or electrical system. Instead, use a properly rated extension cord to plug appliances into an outlet on the generator for power.

When not in use

Operate your generator once a month for 10 minutes to ensure it is running properly. Keep your generator well maintained and follow all manufacturer’s instructions. Have a standby generator installed in an easily accessible, weatherproof area.
