Is Water Damaged Electrical Equipment Safe, and What Should You Do?

Is water damaged electrical equipment dangerous to touch?

Yes. Treat any electrical equipment that was submerged in or came into contact with water as unsafe until a licensed electrician has checked it. Do not touch wet outlets, panels, cords, or appliances, and do not step into standing water to reach them.

For safety reasons, Schneider Electric's storm response FAQ says electrical equipment that has been submerged or come into contact with water needs to be replaced. The City of St. Petersburg, Florida, agrees that submerged circuits are typically not safe to energize.

• Wet outlets and switches
• A wet panel or breaker box
• Wet cords and power strips
• Wet appliances

Contact counts, not only flooding

This replace rule covers equipment that came into contact with water, not only equipment that sat under floodwater. No source gives a water-height number, so this article does not use one.

This danger starts the moment water reaches a plug or panel, often the same moment you are also working out what to do in the first hour after a pipe bursts.

How do I cut the power if I cannot reach the breaker box dry?

Turn off power at the breaker only if you can reach it without standing in water. If you cannot, call your utility and ask it to disconnect power at the meter before anyone goes into the flooded area.

Call the utility to disconnect at the meter

Utilities differ. ComEd, an Illinois utility, can shut off some smart meters remotely once you call. Find your own utility's number on your bill or its website; this article does not publish one utility's number as a general number.

Before you touch anything near the panel, it helps to also know how to find your main water shutoff valve, since stopping the water is usually the first move.

Can I turn the power back on myself?

No. Keep the power off until a licensed electrician or electrical contractor inspects the system.

The Texas Department of Insurance likewise advises having a qualified electrician evaluate water damaged electrical equipment before it is used again. Whether a homeowner may legally reconnect power in your state is not confirmed here, so check with your local building department.

These are examples from one state, city, or utility, not national rules; no national rule is confirmed.

Who decides, by state or city

Rules vary from place to place. Ask your local building department or your electrician which inspection applies where you live.

Which water damaged electrical equipment has to be replaced?

Equipment that was submerged in or came into contact with water must be replaced. Molded-case circuit breakers, outlets, switches, dimmers, and GFCIs or AFCIs are all named on the National Safety Council's replace list, citing the Electrical Safety Foundation International.

This National Safety Council list, citing the Electrical Safety Foundation International, was written mainly for facilities and plants, but it does name the parts found in a home: outlets, switches, dimmers, breakers, and GFCIs.

Why the replace list reads like an industrial list

ESFI's guidance is aimed at commercial and industrial equipment, so it also names items like switchgear and transformers that a home does not have. Wiring hidden inside a wall can also be reached by water long before you see a stain; see what water dripping down a wall means for that angle.

Can water damaged electrical equipment be dried or reconditioned?

Drying does not make water damaged electrical equipment safe. Larger equipment may sometimes be reconditioned, but only a local electrical contractor or service technician can decide that, not the owner. Do not dry, rinse, or clean damaged equipment to reuse it, including with a fan, hair dryer, or heater.

The National Safety Council, citing the Electrical Safety Foundation International, warns that any water-damaged equipment, even if thoroughly dried, still poses a serious long-term safety and fire risk if it is not properly reconditioned. Schneider Electric's storm response FAQ adds that trying to reuse damaged equipment by air drying, rinsing, or cleaning it is not safe.

• Can sometimes be reconditioned: larger equipment, only after a qualified local contractor or technician decides and the manufacturer is contacted, per the Texas Department of Insurance.
• Cannot be reused by drying, rinsing, or cleaning: any equipment that was damaged by water, per Schneider Electric's guidance.

Reconditioning adds its own cost on top of the water damage itself; see our guide to what water damage restoration usually involves and costs for how that typically breaks down.

Fan, hair dryer, or heater?

No. Hair dryers and heaters are not named in any confirmed source as a safe way to dry electrical equipment. The same warning against air drying applies, and drying alone still leaves the long-term fire risk the National Safety Council describes.

What about appliances like the furnace, water heater, or fridge?

Minnesota's guidance says submerged furnaces, water heaters, and dishwashers must be replaced. No confirmed source gives a rule for refrigerators, washers, dryers, sump pumps, HVAC condensers, or electronics, so the general contact rule applies and the manufacturer or a technician should make the call.

The Minnesota Department of Labor and Industry's guidance names these three appliances specifically. Treat anything else that got wet the same way: assume it needs a professional opinion before it runs again.

What if the breaker trips, an outlet is warm, or a GFCI will not reset?

Treat these as reasons to stop and call a licensed electrician, not as problems to reset and retry. No confirmed source lists these signs or gives a waiting time, so the only sourced action is to keep the power off until an electrician inspects the system.

• A breaker that trips repeatedly
• An outlet that feels warm or buzzes
• A burning smell near a panel, outlet, or appliance
• A GFCI that will not reset
• A discolored or corroded switch or outlet

If you smell smoke or burning, leave the building and call 911 or your fire department. For everything else on this list, keep the power off until a licensed electrician or electrical contractor inspects the system, the same rule Schneider Electric's storm response FAQ gives for any water-damaged system.

Does water damage to electrical equipment change with sewage or saltwater?

No confirmed source sets a different replace rule by water type. The sourced rule is contact with water, so any floodwater contact falls under the same rule, and you should tell the electrician what kind of water it was.

If the water came from a sewer, see what to do immediately about a sewer backup in the basement.

Tell the electrician:

• The water source: rain or supply water, sewage, muddy floodwater, or saltwater
• How long the equipment sat in the water

This helps the electrician judge the equipment faster, even though no source here sets a separate rule for contaminated or salt water.

Does insurance pay for electrical damage and ruined appliances?

Homeowners insurance may help pay to replace appliances and other belongings, but coverage depends on your policy and the cause of loss. This article does not confirm whether any policy covers flood damage or wiring, so check your policy and ask your insurer. This is general information, not insurance advice; always check your own policy.

• Photograph and video the equipment and any water marks before anything is touched.
• Keep the electrician's written evaluation for your claim file.
• Ask your insurer which cause of loss your policy covers.

A burst pipe and a flood are often treated differently by insurance. See whether homeowners insurance covers a burst pipe for how that distinction usually works.
