Treat exposed wires and storm-damaged panels as energized. If you can reach it safely from a dry spot, shut off the main disconnect; don’t re-energize wet equipment. Stay out of standing water, and don’t touch outlets, switches, or appliances with wet hands. Keep at least 30 feet from downed lines and anything they’re touching, and call the utility. Run generators outdoors 20 feet away; never backfeed. Next, you’ll see what to check until an electrician arrives.
Do a Quick Electrical Safety Check After a Storm
After the storm passes, do a quick electrical safety check before you step into wet areas or touch any wiring. If you can safely reach the service equipment, shut off the main disconnect to reduce shock risk; don’t energize a storm-damaged panel. If you can’t turn it off safely, call the utility. If a panel or branch circuits got wet, open breakers or remove fuses only when you’re dry and stable, and keep the area ventilated.
Stay out of standing water until you’ve confirmed power is off, and don’t touch outlets, switches, or appliances with wet hands. Wear rubber boots and gloves when you inspect wet zones. Flooding can lead to short circuits and electrical shocks in homes. Then do a visual check for exposed conductors, loose terminations, corrosion, moisture in enclosures, and damaged outdoor receptacle covers. Unplug sensitive electronics, don’t use damp equipment, and replace damaged surge protectors. Test GFCIs; if they fail or are water-damaged, get a licensed electrician.
Stay 10 Feet From Downed Power Lines
Even if the line looks quiet, treat every downed power line as energized and keep back far more than the “10‑foot rule” used for overhead conductors—maintain at least 30 feet of clearance (and more in rain, standing water, or around higher‑voltage transmission lines). ESFI warns the ground can be energized up to 35 feet from the contact point, so don’t guess based on sparks or sound. Increase your distance for transmission circuits; for voltages above 350 kV, stay at least 50 feet away. Don’t touch anything the line could be touching: fences, guardrails, pipes, buildings, plants, telecom cables, maintenance hole castings, or rebar can all become energized and carry current long distances. If you’re too close, back away by shuffling—keep both feet on the ground, take small steps, and don’t run. Call the utility; call 911 if contact occurred. Report downed lines immediately using your utility’s 24/7 trouble line and give the exact location while you wait at a safe distance.
Avoid Flooded Areas and Wet Outlets After Storms
Storm damage doesn’t stop at downed lines—floodwater and wet outlets can energize floors, walls, and anything you touch. Assume any waterline has energized wiring or receptacles beneath it, and don’t enter flooded rooms. Even a thin film of water on a floor lowers your body’s resistance and raises shock risk. Floodwater also carries corrosive contaminants that can degrade insulation and terminals, creating hidden faults and future fire hazards inside walls. Homeowners should prioritize storm preparedness to minimize risks during such emergencies.
Don’t touch wet switches, outlets, cords, or appliances, and never stand in water to unplug anything. If rising water threatens outlets, shut off breakers from a dry, accessible location; if that’s not possible, keep clear and leave power off. If you can’t safely cut power, contact the utility company or a licensed electrician for safe disconnection. After water recedes, treat every previously submerged receptacle, switch, panel component, and breaker as damaged—NEC requires replacement of submerged devices. Keep circuits off until a qualified inspection and testing confirm safety.
Use Generators Safely: and Know When to Call an Electrician
When the power’s out and you’re relying on a portable generator, set it up and connect it like a temporary power source—not a substitute for utility wiring. Place it outdoors only, at least 20 feet from doors, windows, and vents, with 3–4 feet clearance on all sides, and aim exhaust away from openings to limit CO infiltration. Never run it in a garage, shed, basement, or any partially enclosed area; CO is odorless and can linger after shutdown. One portable generator can emit as much carbon monoxide as 100 cars. Use a battery-operated CO detector, and prefer units with CO shutoff. It’s crucial to also understand your home systems to ensure safe operation while you wait for professional assistance.
Keep the unit dry on a stable surface under an open canopy, and don’t handle plugs with wet hands. Use heavy-duty outdoor extension cords with intact grounding pins, match cord and generator ratings, and stagger loads to prevent overload. Shut down and cool before refueling. Never backfeed a panel; call a licensed electrician to install a transfer switch.
Frequently Asked Questions
Will My Homeowners Insurance Cover Repairs for Storm-Damaged Wiring?
Yes—your homeowners insurance will often cover repairs for storm-damaged wiring if a covered peril caused it (lightning, wind, hurricane, or a tree fall) and the damage is sudden and accidental. You’ll likely need a licensed electrician’s report and photos to document cause and scope. You won’t get coverage for age-related deterioration, outdated systems, poor maintenance, or faulty installation. Check deductibles, windstorm exclusions, and surge-damaged electronics limits.
How Long Should I Wait Before Turning the Main Breaker Back On?
You shouldn’t turn the main breaker back on until a licensed electrician (and your utility, if the service was impacted) clears the system—there’s no safe fixed wait time. Keep it off if you had flooding, exposed/chafed conductors, tripped breakers, burning odors, or flickering before outage. Don’t test “just to see.” Have them inspect service entrance, neutrals, and water-exposed circuits with proper instruments.
What Are Signs of Electrical Damage Hidden Behind Walls or Ceilings?
You’ll spot hidden electrical damage by watching, listening, and feeling: lights that flicker or dim; outlets or switches with discoloration, scorch marks, or melted plastic; paint that peels or cracks, plus ceiling water stains. You’ll hear buzzing, crackling, humming, or faint panel clicking. You’ll notice hot outlets, warm wall areas, or a burning odor. You may see frequent breaker trips, dead outlets, sparking, or sagging ceilings.
Can Lightning Damage Electronics Even if the Power Never Went Out?
Yes—lightning can damage your electronics even if power never goes out. You can get EMP and induced transient surges on utility, coax, or phone lines from nearby strikes, driving kilovolt spikes and high‑frequency harmonics into sensitive microprocessors. You’ll often notice sudden shutdowns, flashing displays, or burnt odors. You should disconnect power and signal cables during storms when possible, and use quality surge protection, knowing it won’t stop a direct strike.
Should I Replace Surge Protectors After a Major Storm or Power Surge?
Absolutely—replace surge protectors after a major storm or significant surge; they can wear out like they’ve been hit by a thousand tiny hammers. You can’t “reset” lost joule capacity, and protection may be compromised even if outlets still work. If the indicator light is red/off, replace now. After lightning or utility restoration, swap them proactively. Use UL 1449-listed protectors, consider a whole-home unit, and verify grounding.
