Your Home’s Electrical System After a Storm, Flood or Fire

After a storm, a flooded basement, a burst pipe or a fire, getting the power back on is one of the first things everyone wants. It is also one of the most dangerous steps if it’s done too soon. Water and heat damage electrical equipment in ways you can’t always see, and re-energizing damaged wiring can cause shocks and fires days later.

Here’s what to do, and not do, with your home’s electrical system after damage.

Right After the Damage

• Stay out of standing water if the power might be on, and don’t touch the panel while standing in water or if it’s wet.
• Stay away from downed lines. Assume every downed line is live and report it to your utility.
• If it’s safe to reach the main breaker from a dry spot, shut it off. If not, call your utility to disconnect the service.
• Don’t turn power back on to anything that got wet, until it’s been checked.
• Use a generator only outside, far from the house, and never plug it into a wall outlet. See portable generator safety.

What Water Does to Electrical Equipment

Floodwater carries dirt, debris and contaminants that stay behind after things dry. Inside breakers, GFCI and AFCI devices, outlets and switches, that residue and the corrosion it causes can make them fail to protect you, even though they look fine. The National Electrical Manufacturers Association’s guidance on water-damaged equipment calls for replacing many items that have been submerged, including:

• Circuit breakers, fuses and panelboards that were under water
• GFCI and AFCI devices
• Outlets, switches and dimmers
• Some types of wire and cable, depending on how they’re rated
• Smoke alarms, and electronics in water heaters, HVAC and appliances

A licensed electrician evaluates what was exposed and how, and tells you what must be replaced and what can be cleaned and tested.

After a Fire

Heat can damage wire insulation well away from the visible burn, and firefighting water adds water damage. Smoke residue is corrosive. After a fire, the electrical system should be evaluated before it’s re-energized, and your local building official may need to approve reconnection.

Getting Back to Power

1. Make it safe: disconnect damaged circuits and, where needed, set up temporary power so cleanup and drying equipment can run.
2. Evaluate: inspect the panel, wiring, devices and equipment, and document what was affected.
3. Repair or replace, with a permit where required.
4. Inspect and re-energize, in some cases only after the building official approves.

Working With Your Insurance and Restoration Company

Most water and fire losses involve a restoration company and an insurance adjuster. We work alongside them: an itemized scope of the electrical damage, photos, and repairs coordinated with the drying and rebuild schedule. Keep copies of everything for your claim. Restoration contractors can see our guide for restoration firms.

Frequently Asked Questions

Can I turn my power back on after a flood?

Not until a licensed electrician has checked anything that got wet. Breakers, outlets and other devices that were submerged often have to be replaced even if they look fine.

Do outlets need to be replaced after water damage?

Outlets, switches, GFCIs and breakers that were under water are generally replaced, following manufacturer and industry guidance.

Will insurance cover electrical repairs after a flood or fire?

It depends on your policy; flood is often separate coverage. An itemized electrical scope with photos helps your adjuster evaluate the claim.

Is it safe to run a generator after a storm?

Yes, outdoors, at least 20 feet from the house, with exhaust away from doors and windows, and connected through an inlet and interlock or transfer switch, never a wall outlet.
