A quick blue spark when you plug something in can be normal. Sparks that are large, yellow or repeated, a sizzling sound, scorch marks or a burning plastic smell are not.
Do this first
- If you see flames or heavy smoke, get everyone out and call 911
- If it is safe, switch off the breaker for that circuit, or the main breaker if you are not sure which one
- Do not touch the outlet or pull the plug while it is sparking
- Do not use water on an electrical fire
- Keep the circuit off and call an emergency electrician
What causes a sparking outlet
- Loose connections, especially wires pushed into the back of the outlet instead of fastened under screws
- Worn contacts that no longer grip the plug
- Moisture in kitchen, bathroom or outdoor outlets
- An overloaded circuit heating a weak point
- Aluminum wiring connections that have loosened over time
What a burning smell means
Overheated insulation and plastic smell sharp and fishy. The source may be an outlet, a switch, a light fixture or the panel itself. If you cannot find it, treat the whole area as suspect and shut off power.
The repair
An electrician opens the device, cuts back damaged wire, replaces the outlet and checks the rest of the circuit for the same fault. Kitchens, bathrooms and exterior outlets should have GFCI protection. Repeated problems in an older home may point to wiring that needs replacement and are a good reason to book an electrical inspection.
Check your alarms
A scare like this is a reminder to test smoke alarms. Units older than ten years should be replaced. See smoke detector wiring.
