Start with your range's nameplate

Do not guess your stove's draw. Ranges vary widely by size, burner count, and oven type. Look for the rating label, usually inside the oven door frame, under the cooktop, in the storage drawer, or on the back. The owner's manual and the maker's spec page list it too.

The label gives a rating in watts or kilowatts, along with the voltage the range needs. That figure is roughly the most the range can pull with every element on. You rarely run everything at once, but sizing to the nameplate keeps you from tripping the generator when you do.

• Write down the watt or kW rating and the voltage.
• If it lists only amps, multiply amps by volts to get watts.
• Note whether it is a plain electric, smooth-top, or induction range, since the label rating is what counts either way.

Add up everything else you want running

The range is rarely the only load. During an outage you may also want the refrigerator, some lights, a furnace fan, and phone chargers. Each one adds to the total the generator must carry.

For example, if your range label says 8,000 watts and your refrigerator label and other circuits add 2,000 running watts, you need a generator with more than 10,000 running watts on the fuel you plan to use. Leave some headroom so the generator is not pinned at its limit.

Motor loads like refrigerators and well pumps need extra power for a moment when they start. Check each appliance's label or manual for starting draw, or measure plug-in loads with a watt meter. Heating elements in a range do not have a motor surge, but your other loads might.

Read the generator's spec sheet the right way

Generators list running watts and starting watts. Size to running watts. Starting watts only cover brief surges.

Dual fuel models usually list separate ratings for gasoline and propane, and the propane rating is often lower. Use the rating for the fuel you will actually run. The listing on this page is listed with electric start and dual fuel; check its spec sheet for running watts on each fuel and for output at the voltage your range needs before you count on it for a range.

• Confirm the generator lists output at the voltage on your range's label.
• Use running watts, not starting watts, for your math.
• Check the rating on propane if you plan to use it.
• Look at fuel tank size and runtime at your expected load.
• Read the warranty terms and service options.

How a range actually connects to a generator

An electric range is hardwired or uses a dedicated plug, so you cannot run an extension cord to it. It runs from the generator through your home's panel, using a transfer switch or interlock installed by a licensed electrician.

Generator outlets and house inlets come in different plug types. Which outlet and cord are safe for your house is the electrician's call, so ask them to confirm the generator's outlet type before you buy. Never backfeed power through a dryer or range outlet; it can energize utility lines and endanger line workers and your home.

Run it safely

Never run a generator indoors, in a garage, or near windows, doors, or vents. Exhaust contains carbon monoxide, which you cannot see or smell. Place it well away from the house and put battery-backed carbon monoxide alarms inside.

To ease the load, cook with fewer burners at a time and avoid running the oven while other large appliances cycle. That keeps you inside the generator's limit and stretches fuel.
