Make a Generator Outage Plan Sheet: Circuits, Cords and Contacts

A generator outage plan sheet is one page, kept with the manual, that says what you will power, how each item gets its power, where the generator sits and who to call when something goes wrong. Write it on a calm day, because the first hour of a real outage is a bad time to decide which cord goes where. Everything below is a fill-in exercise for your household. It gives no wattage figures, since those come from your appliance labels and your generator manual.

Why a written sheet beats memory

Most outage mistakes come from improvising in the dark. Someone grabs the wrong cord, runs the unit too close to the house, or forgets that the furnace blower is hard-wired and cannot be plugged in. A page on the wall or in the manual folder turns those decisions into a checklist anyone in the house can follow, including the person who did not buy the generator.

The sheet is not a hardware guide. For gear, see our emergency backup power guide. For a winter-specific version of the same thinking, our winter storm prep guide goes further. This article is only about getting the plan onto paper.

Block 1: what must run

List every item you would want powered, then rank them. Start with what protects health and property, such as medical equipment, a refrigerator or freezer, a sump pump or a heat source with a powered fan, then move to comfort items such as lights, phone chargers and a router. Medical devices deserve a separate conversation: the Red Cross advises talking with your doctor or device provider ahead of time about a plan, and leaving for a place with power if you depend on powered medical equipment.

Use a table like this one, and copy it onto paper.

The "motor or heater" column matters because motors can ask for much more power when they start than when they run, and heating elements ask for a lot continuously. Our running versus starting watts explainer covers the idea,. Write the numbers on your sheet only after you read them from labels and your manual.

Block 2: how each item connects

For every line on the list, pick one of three paths. The first is plugging the appliance straight into the generator with a short cord. The second is using a heavy-duty, outdoor-rated extension cord, rated for the total connected load, which is what University of Georgia Cooperative Extension advises. The third is a house connection through equipment installed by a licensed electrician, such as an inlet with an interlock or a transfer switch.

The Electrical Safety Foundation International says a transfer switch is the only safe way to power a home's electrical system from a generator, and warns that backfeeding can injure utility crews. If a circuit cannot be reached by cord, that is a job for an electrician, not a workaround. Our CO and backfeeding guide explains the risk.

Next to each line, write the cord type and its length, and check that the plug matches the outlet. Our plug types guide helps with that. Store the cords near the generator and note their condition; our cord care guide covers inspection.

Block 3: where the generator sits

Draw a tiny map. Mark the spot outdoors where the unit will run, the route the cords take and the windows, doors and vents nearby. University of Georgia Extension advises a dry surface under a canopy-style outdoor structure, away from the house, and not running a generator in wet weather. Choose a spot that stays dry.

Add the CO alarms to the same page. The Red Cross suggests at least one carbon monoxide detector on each level of the home. Test the batteries before storm season and write the date on the sheet.

Block 4: fuel, oil and who does what

Write down where fuel is stored, in sealed, labeled containers kept out of living areas, as UGA Extension advises, and the date it was bought. Note the oil type your manual calls for and where the spare oil lives. Then assign jobs: one person starts and stops the unit, one watches fuel and oil, one handles the cords. In a small household that may be two people sharing three jobs, but writing it down avoids the argument.

Add one rule to the sheet: shut the generator off and let it cool before refueling. UGA Extension notes that spilled gasoline on a hot unit can ignite. For oil and refuel timing across a long outage, check the manual for oil and refuel timing.

Block 5: contacts

Keep a paper list, since phones die. The Red Cross suggests keeping a paper copy of your support contacts. For the generator, include:

• Your electrician, and the one who installed any inlet or transfer equipment.
• Your utility's outage line, plus a note on how to report downed lines.
• The generator maker's support line and your model and serial numbers.
• A small-engine service shop that works on your brand.
• A neighbor or relative who can help or who needs help.
• Your doctor or equipment provider, if anyone relies on powered medical gear.

Keep it current

Review the sheet when you buy an appliance, change a cord or run the yearly test. Our pre-season load test routine is a good moment to confirm every line still works as written. Fix anything that does not, and date the page. If the plan changes hands, for example when a relative house-sits during storm season, walk that person through the sheet once and let them start the unit while you watch. A plan only one person understands is not much of a plan.
