Have it checked: a spark at the plug
No source we trust calls an outlet spark normal. Stop using that outlet, watch for warning signs, and have a licensed electrician check it.
Why this happens
Family Handyman treats sparks from an outlet as an immediate danger, and CPSC counts sparks emitted from a receptacle as a fire hazard condition. We could not find an authoritative source that says a small spark is harmless. Any spark that repeats, makes noise, smells or leaves a mark means breaker off and electrician right away.
What to do right now
- Stop using that outlet. Leave the device unplugged, gripping the plug body with dry hands to remove it.
- Check the plug prongs and the outlet face from a safe distance for black marks or melting.
- If you see a mark, smell burning, or it sparks again, turn the breaker for that outlet OFF at the hinged panel door and leave it off.
- Book a licensed electrician to check the outlet.
When to stop. A second spark, any sound, smell or mark: breaker off now.
What to tell the licensed electrician
- That it sparked once when you plugged in or unplugged, and what device it was.
- Whether the plug fits snugly or is loose.
- Whether the outlet has ever felt warm or smelled.
