How to Prepare Your Electrical System for a Tornado

Tornadoes can strike quickly and leave serious damage in their path, including power outages and dangerous electrical hazards. Here’s how to get your home’s electrical system ready before, during, and after a tornado.

✅ Before the Tornado

Install a Whole-House Surge Protector: A strong surge can come from lightning or nearby power line damage.

Secure Outdoor Electrical Equipment: Ensure outdoor outlets, lighting, and HVAC connections are weatherproof and protected.

Backup Generator Setup: Have a portable or standby generator installed by a licensed electrician so it’s ready when the grid fails.

Know Your Breaker Box: Make sure all adults in the home know how to shut off power in case of an emergency.

⚠️ During the Tornado Warning

Unplug Major Devices: TVs, computers, and appliances should be unplugged to protect from surges.

Avoid Electrical Appliances: Don’t use wired devices during lightning activity.

Shelter Safely: Stay away from electrical panels, outlets, and wires while sheltering in place.

🔌 After the Storm

Inspect for Water Damage: If flooding occurred, do not use power until inspected by a professional.

Avoid Downed Wires: Always assume downed lines are live — call utility services immediately.

Call an Electrician: Have a professional inspect the panel, outlets, and any outside systems before restoring full power.
