What to Do If You See Sparks from an Outlet After a Storm in St. Louis

 

Immediate Actions to Stay Safe

 

• Turn off the circuit breaker that controls the outlet. This cuts power and stops sparks right away.
• Unplug any devices from the outlet without touching the outlet cover or wires.
• Keep everyone, including pets, away from the outlet until it is fully checked.
• Do not use water or try to put out any sparks yourself—it can cause electric shock.

 

Understanding Why Outlets Spark After a Storm

 

When lightning strikes nearby or heavy winds damage power lines, a sudden surge of electricity or a drop in voltage can travel through wiring. This rush of electricity can:

• Overload wiring connections, causing small arcs (sparks) of electricity.
• Damage the outlet’s internal parts, creating loose connections that spark when you plug or unplug.
• Allow moisture from rain or humidity to enter the outlet, creating a path for electricity to jump.

Sparks are a sign of a serious electrical problem. They can lead to fires, shocks, or permanent damage to your home’s wiring.

 

How to Safely Shut Off Power

 

Locate your home’s main electrical panel (breaker box), usually in a garage, basement, or utility closet. Then:

• Open the panel cover and find the breaker labeled for the room or area with the sparking outlet.
• Flip that breaker fully to the “off” position. If you’re unsure which one, turn off the main breaker to cut power to the whole house.
• Keep the main panel closed and do not touch any internal wires.

Turning off power stops further damage and reduces fire risk until a professional can inspect the wiring.

 

When to Call a Professional Electrician

 

You should call a licensed electrician immediately if you see sparks from an outlet. Electrical work can be dangerous, and only a trained technician should:

• Open up the outlet box to look for burnt wires or loose connections.
• Use special tools (like voltage testers and insulation resistance testers) to check if current is safe.
• Replace damaged wiring, outlets, connectors, or install safety devices like arc-fault circuit interrupters (AFCIs).

A qualified electrician knows local codes, uses safe practices, and carries insurance in case of mishaps.

 

What a Professional Electrician Will Do

 

Once on site, the electrician will:

• Confirm that the power is off with a voltage tester.
• Remove the outlet cover and inspect the wiring for scorching, frayed insulation, or loose terminals.
• Replace the outlet if it’s cracked or damaged, using the correct amperage and terminal type.
• Check surrounding outlets and the wiring run for signs of storm damage or moisture intrusion.
• Install protective devices, such as surge protectors or GFCI outlets, to guard against future surges.
• Test the repaired circuit under load to ensure it operates safely and meets electrical code requirements.

 

Preventing Future Electrical Sparks

 

After repairs, you can reduce risk by:

• Installing surge protectors on major appliances and electronic devices.
• Adding arc-fault circuit interrupters (AFCIs) to critical circuits—these automatically shut off power when a spark is detected.
• Keeping outlet covers tightly closed and weatherproof on exterior outlets.
• Checking your home’s grounding system to make sure it safely directs excess electricity into the earth.
• Scheduling a routine electrical inspection every few years, especially after severe storms.
