How to use a generator during a power outage

Using a generator during a power outage follows one order. Prepare, place, connect, start, watch the load, then shut down. Your manual sets the exact startup order and watt limits for your model.

Follow your manual for startup order and load limits. Place engine generators outdoors, at least 20 feet from the home, exhaust pointed away. Use a listed transfer switch for panel power. If outdoor space is not possible, a battery power station is the safer indoor choice.

Prepare before the outage

Read your manual before you need it. Write down rated running watts and starting watts. These change by model and fuel type.

Confirm your fuel type. It may be gasoline, propane, natural gas, or stored battery charge. Store gasoline in approved containers outside living areas, away from any flame or pilot light, and keep propane cylinders upright and outdoors, as your manual says.

Put a carbon monoxide alarm in your home now. Check its batteries today. A transfer switch for panel power needs a licensed electrician.

Place the generator safely

Run engine generators outdoors, at least 20 feet from the home. Point exhaust away from windows and doors. This is CPSC guidance (https://www.cpsc.gov/Safety-Education/Safety-Education-Centers/Carbon-Monoxide-Information-Center).

Never run one in a house or garage, even with the door open. Carbon monoxide has no smell. It builds up fast in closed spaces.

Set the unit on dry, flat ground. Check your manual before running it in rain (https://www.cpsc.gov/s3fs-public/Portable_Generator_Safety_Alert_2017_5123.pdf). Never touch the unit with wet hands.

Connect equipment the right way

Never plug a generator into a wall outlet. This sends power backward into the grid. It risks utility workers and can damage wiring (https://support.generac.com/s/article/How-to-do-a-manual-power-transfer-using-a-portable-generator-and-manual-transfer-switch).

A listed transfer switch is the safe way to power several circuits. It must match your generator and panel. A licensed electrician sizes and installs it.

For one appliance, plug straight into the generator with a heavy-duty cord. A single-circuit switch rated for 1875 running watts can serve one dedicated appliance (https://api.reliancecontrols.com/media/DAFD6560942639833572/DAFD6584409607368668/DAFL6584444121126561.pdf).

Start up and watch the load

Start the generator first. Let the engine settle, as your manual describes. Add devices one at a time.

Add up running watts for everything you plan to use together. Then add the single biggest gap between one appliance's starting watts and its running watts. This covers one unit starting at a time, not several at once.

Rated output is a screening number from the maker. It does not guarantee your generator will start a specific well pump or fridge.

Watch the load as you run it. If the engine bogs down, unplug something before adding more.

Handle fuel and refueling with care

Shut the generator off and let it cool before refueling. Never refuel a hot or running engine. Spilled fuel near hot parts is a fire risk.

Propane, natural gas, and tri-fuel units draw from a tank or line. This changes how you refuel, not where you place the unit. Every engine generator still makes carbon monoxide. The 20 foot outdoor rule applies to all of them.

Shut down the right way

Turn off and unplug appliances before you shut down the generator. Let the engine cool before you cover it. Check oil level and other basic items from your manual.

Write down hours run and fuel used after each outage. This record helps if you call a technician later.

When outdoor placement is not an option

Some homes have no spot 20 feet from windows and doors. Running an engine generator there is not safe under CPSC guidance.

A battery power station is the documented stand-in. Units like the BLUETTI AC200L (2048 Wh, 2400 W rated output) or the Jackery Explorer 2000 v2 (2042 Wh, 2200 W rated output) run indoors with no exhaust (https://www.bluettipower.com/products/ac200l-portable-power-station, https://www.jackery.com/products/jackery-explorer-2000-v2-portable-power-station).

A battery unit has a fixed watt-hour capacity. Runtime depends on what you plug in.

How to Use a Generator During a Power Outage Verdict

How to use a generator during a power outage? Follow your manual every time you use a generator during a power outage. Keep engine units outdoors, 20 feet from the home, exhaust pointed away. Never backfeed a wall outlet.

If your home has no safe outdoor spot, a battery power station skips the exhaust problem entirely.

Can I run a generator in my garage with the door open?

No. CPSC guidance says engine generators should never run indoors or in a garage, even with doors open. Carbon monoxide builds fast in enclosed spaces. Keep the unit outdoors, 20 feet from the home.

What counts as starting watts versus running watts?

Running watts are what an appliance draws once it is on. Starting watts are a short, higher burst some motors need to switch on. Your manual lists both numbers for your generator model.

Is a transfer switch the same as backfeeding?

No. A listed transfer switch isolates the generator from the utility line. Backfeeding means plugging a generator into a wall outlet without one. That sends power backward into the grid and risks utility workers.

What is the safe alternative if I cannot place a generator outdoors?

A battery power station, charged by an outlet or solar panel, is the documented option for indoor use. It has no engine and no exhaust, so the outdoor clearance rule does not apply to it.
