Power generators come in two primary forms: portable and standby.
A portable generator can be used to power select items in your home during a blackout. It's most often powered by gasoline and requires refueling after prolonged use. To prevent carbon monoxide poisoning, a portable generator can never be used inside. You start the generator manually by pulling a cord.
A standby generator can be wired into a sub panel by an electrician or plugged directly into appliances with heavy-duty extension cords. It can only supply enough electricity to power up to four outlets or a few circuits when wired into a sub panel.
A standby generator is permanently installed outside your home. Most often powered by petrol or diesel but can also be powered by natural gas or liquid propane in very rare cases, standby generators can run on local utility lines, meaning no refueling is required.
The best part about standby generators is they automatically sense power outages and turn on within seconds of the power going out. This seamless power transfer keeps your home's circuits and appliances up and running like normal. Depending on what size of generator you install, you can choose to power just the essentials or every electrical system in your home.
