What Would Cause an Outlet to Catch Fire?
Grease fires, leaving the stove on, forgetting about a lit candle—these are all obvious fire hazards we expect and worry about in our homes. But what happens when seemingly out of nowhere, an outlet catches fire? What do you do, and what was the cause? Learn more about the common reasons an outlet might catch fire and other related questions.
What Causes an Outlet to Burn?
The top causes of an outlet burning or catching fire include:
- Overloaded outlets or circuits. An outlet that has too many cords plugged in can quickly become overloaded with electricity. This can cause overheating that wears down the internal wiring and results in an outlet catching fire.
- Frayed or exposed wiring. Not only is exposed wiring dangerous to be near, but it can also interrupt the flow of electricity, leading to sudden spikes in heat and causing electrical fires.
- Faulty wiring or cords. Similar to a frayed cord, faulty wiring can interrupt the flow of electricity or distribute it unevenly.
- Faulty receptacles or switches. If the receptacle or switch itself is faulty, it can cause missed electrical connections or damage to internal wiring.
- Cracked cover plates. While it may not seem like a major issue, cracked cover plates can allow dirt and debris into an outlet or expose internal wiring. Both issues can result in short-circuiting.
- Old or outdated outlets or breaker boxes. Old outlets can’t keep up with the higher power demands of modern appliances or electronics. Because of this, outlets can quickly become overheated. Even worse, if the breaker box is outdated, it may not trip when it’s supposed to—resulting in short-circuiting.
Old or outdated appliances. Similar to any other outdated electrical work in a home, outdated appliances can be just as much of a hazard. Whether it’s due to damaged wiring, hazardous material, outdated safety regulations, or incompatible wattage for outlets and wiring, old appliances can cause overheating, possibly leading to a fire.

Other Common Electrical Outlet Fire Hazard Questions
Is a Dead Outlet Dangerous?
Yes. A dead outlet can be a sign that wires are loose or damaged. There could also be a short circuit, a faulty outlet, or a faulty breaker box. This could all result in a fire if not handled correctly.
However, a dead outlet could also simply mean the circuit is overloaded. Additionally, it could just be a faulty cord or appliance, or if it’s a GFCI outlet, it may just need to be reset.
Is a Burnt Outlet Dangerous?
Yes. If an outlet has already burned or sparked in some way, there’s likely faulty or damaged internal wiring somewhere. It’s best to call an emergency electrician right away to handle the issue.
Can a Wet Electrical Outlet Cause a Fire?
It depends. If the outlet is severely water damaged, or the amount of current flowing through the water is high, it could result in a fire. Additionally, even if a small amount of moisture enters the outlet, it could result in corrosion over time. So, if recent water damage occurred in the home, it’s important to have a restoration specialist address it as quickly as possible.
Can an Outlet Catch Fire with Nothing Plugged In?
Yes. This can happen for several reasons including those listed above such as faulty, damaged, or outdated wiring and receptacles. Regardless of whether something is plugged in, this damaged internal wiring can short-circuit and continue corroding, resulting in an unexpected fire.
Can a Buzzing Outlet Cause a Fire?
Yes. A buzzing outlet is a sign that something isn’t working properly. Usually, this buzzing sound is coming from the vibrating caused by loose connections. These loose connections limit the proper flow of electricity and can result in damaged wiring and short-circuiting.
Can Plastic Outlet Covers Catch Fire?
Yes. Unfortunately, by design, outlet covers create a greater risk of outlets overheating and potentially catching fire. While covers may be a helpful solution in childproofing outlets, it’s better to install childproof outlets that feature spring-loaded shutters when not in use.
How To Prevent Outlet Fires
The best way to prevent outlet fires in a home is by following these safety practices:
- Never overload electrical outlets.
- Only use GFCI outlets near water.
- Keep flammable items a safe distance from outlets.
- Unplug appliances when not in use.
- Don’t use outdated appliances.
