Generator Install questions, answered by experts

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
