How to Prepare Your Home for a Power Outage: A Practical Checklist
Power outages are rarely convenient and sometimes dangerous. Whether you’re preparing for hurricane season, winter ice storms, or wildfire-related shutoffs, having a plan before the lights go out makes every hour of an outage more manageable. This checklist covers every major preparation step.
Step 1: Assess Your Power Needs
Start by identifying which systems are critical during an outage. Most households prioritize: refrigerator/freezer, HVAC or at least window AC, well pump (if applicable), medical equipment, lighting, and phone charging. Make a list of the running wattage of each item — your generator needs to handle the total continuous load, plus startup surge for motors like the AC compressor and well pump.
Step 2: Choose and Size a Generator
For most homes, a portable generator in the 5,500W–8,000W range handles the essentials comfortably. For whole-home backup that includes central AC, you’ll want 7,500W or more. Key requirements for compatibility with meter-mounted transfer switches like GenerLink: 120/240V dual voltage output, 4-prong twist-lock outlet (L14-30 or L14-50), and no full-panel GFCI.
Step 3: Install a Proper Transfer Switch
Never connect a generator directly to your home’s wiring via an outlet — the practice is illegal, voids insurance, and creates a backfeed hazard for utility workers. A transfer switch is required by law in most jurisdictions. GenerLink installs at the utility meter in under 30 minutes and powers your entire panel — no breaker box work required.
Check with your utility company before buying. Most utilities require approval before installing any transfer switch. Use our Utility Approval Checker to verify your service area.
Step 4: Store Fuel Safely
A 5,500W generator running constantly burns about 0.75 gallons per hour. Plan on 5–10 gallons per day for essential loads. Store fuel in approved containers away from the home, rotate it regularly (gasoline degrades in 3–6 months without stabilizer), and always treat stored fuel with a stabilizer like STA-BIL.
Step 5: Protect Your Appliances
Power restoration can cause surge events that damage refrigerators, HVAC control boards, and other sensitive electronics. If your GenerLink model includes surge protection (MA23-S or MA24-S), your hardwired appliances are covered by a 15-year warranty against surge damage up to $10,000 per residence.
Step 6: Have a Communication Plan
Keep a battery-powered or hand-crank weather radio, backup phone chargers, and a list of important numbers available offline. Know your utility’s outage reporting number and have the customer service line saved.
Step 7: Test Everything Before Storm Season
Run your generator under load for 30–60 minutes every few months. Verify the GenerLok cable snaps securely. Check the GenerLink LED indicators confirm proper operation. Replace generator oil per manufacturer schedule. Test your CO detector batteries. A 30-minute test now prevents a 30-minute scramble during an actual outage.
Getting prepared starts with a proper transfer switch. Browse GenerLink transfer switches to find the right model for your home and generator.
