Causes of Wet Outdoor Outlets
There are a few common ways outdoor outlets can get wet:
- Rain, snow or excess moisture seeping into the outlet cover or cracks in the outlet casing
- Sprinklers or irrigation systems spraying directly on the outlet
- Flooding due to heavy storms, burst pipes, etc.
- Accidentally spraying the outlet with a hose or power washer
- Condensation buildup within the outlet casing
Wet weather, outdoor water sources and moisture are unavoidable hazards for outdoor outlets. But it’s important to take precautions to protect outlets from getting drenched.
Dangers of Wet Electrical Outlets
When an outdoor outlet gets wet, there is a serious danger of electric shock or fire. Here are some of the risks:
- Electrocution – Water is an excellent conductor of electricity. Wet outlets can energize standing water and wet grass, posing a fatal shock risk.
- Short circuits – Moisture can cause short circuits, electrical arcing and sparks inside the outlet. This can lead to fires or damage to connected devices.
- Corrosion – Water can corrode metallic outlet parts and wiring. This degrades the outlet over time and causes safety hazards.
- Appliance damage – Any devices plugged into a wet outlet can short circuit and sustain permanent damage.
- Malfunctions – Wet outlets may flicker, stop working entirely or operate unpredictably.
A wet outdoor outlet is extremely hazardous until properly dried and repaired. It should be disconnected immediately.
What to Do If an Outdoor Outlet Gets Wet
If you notice your outdoor outlet has gotten wet for any reason, take these steps right away:
1. Switch Off Power at the Breaker
- Locate the breaker controlling the wet outlet and switch it to the OFF position. This isolates the outlet and prevents accidental shocks.
- Verify power is off by plugging in a tester or lamp. Lack of power confirms the outlet is no longer live.
2. Unplug All Connected Devices
- Unplug everything from the wet outlet, including lights, appliances and extension cords. This protects devices from damage.
- Do not reconnect anything until the outlet has dried completely. Energizing a wet outlet can cause short circuits.
3. Remove the Outlet Cover
- Unscrew the outlet cover plate and remove it to expose the interior of the outlet. This lets air circulate and dry out inner parts.
- Inspect for any standing water, dirt, cobwebs or damage inside the outlet. Make note of any issues.
4. Allow the Outlet to Dry Thoroughly
- Let the outlet dry completely for 1-2 days before attempting to use it again. This gives ample time for moisture to evaporate.
- Aim a fan at the outlet to speed up drying. But do not attempt to dry with a hairdryer or other heat source.
- Check for remaining moisture using an electrical tester. Bone-dry internals are essential before re-energizing.
5. Have an Electrician Inspect Before Using Again
- Even if the outlet appears dry, have an electrician inspect it before switching the power back on.
- The electrician can check for hidden moisture, damage and correct functionality for safety.
- Any damaged parts like wires or terminals should be replaced. The electrician may recommend adding outdoor-rated covers or sealants.
- Request GFCI outlets if not already present. GFCIs provide protection if moisture sneaks in again.
6. Improve Weatherproofing
- Caulk around conduit openings with waterproof silicone to prevent moisture intrusion.
- Add extra weatherstripping inside the outlet cover plate to block water.
- Install outdoor outlet covers that close tighter and have foam gaskets to repel water.
- Use outdoor-rated extension cords with tighter seals if plugging in appliances.
With proper precautions, you can help prevent outdoor outlets from getting wet and avoid the dangers of wet electrical connections. Act quickly if moisture does infiltrate an outlet by following these steps. Stay safe around all outdoor electricity.
Frequently Asked Questions
How soon after an outlet gets wet do I need to take action?
You should disconnect electrical power to the outlet and take steps to dry it immediately. Energized outlets that are wet present an immediate safety hazard.
Is it safe to use a wet outdoor outlet if I have a GFCI installed?
No, you should not use a wet outdoor outlet even with a GFCI. Damage from moisture can prevent the GFCI from tripping correctly. Disconnect the power.
Can I use compressed air to dry out my wet outlet?
Do not use compressed air, as forcing moisture deeper into the outlet can increase damage. Letting the outlet air dry naturally is safer.
How can I prevent my outdoor outlets from getting wet in the future?
Use outdoor outlet covers designed to seal out moisture. Caulk openings. Install GFCIs. Check for leaks in weatherstripping. Ensure outdoor wiring is properly grounded and rated for wet locations.
My outlet won’t turn back on after drying. What should I do?
Don’t attempt to repair it yourself. Have an electrician inspect the outlet for hidden moisture or damage. Corroded or faulty wiring may need replacement before the outlet can be safely re-energized.
