What it usually means

Electricity makes heat wherever it meets resistance. A loose or worn connection, an overloaded cord, or damaged wiring can get hot enough to melt plastic and start a fire. CPSC warns that unusually warm outlets or switches may mean a loose connection that can start a fire (CPSC). Common causes:

  • A loose connectionAt an outlet, switch, light fixture, breaker or in the panel. This is the most common one we find.
  • Too much plugged inPower strips plugged into power strips, or a space heater on an extension cord, can overheat the cord, plug or outlet.
  • A failing appliance or plugA damaged cord or plug can overheat right at the outlet.
  • Older or aluminum wiringIn homes with aluminum branch wiring, CPSC lists hot face plates and the smell of burning plastic at outlets or switches as warning signs (CPSC).

Safe for you to check

  • If you see smoke or fire, get everyone out and call 911. Don’t go back in.
  • If an outlet, switch or cover plate is hot, stop using it. Unplug what’s plugged in if you can do it without touching anything hot, and don’t use that switch (ESFi).
  • If the panel isn’t the hot or smelly part and you can reach it safely, turn off the breaker for that circuit.
  • Warm vs. hot: ESFi says a cover plate that’s warm to the touch may be okay, but hot is not. Some dimmers run warm normally (ESFi, CPSC).
  • Look, don’t touch: brown or black marks around a plate, a melted plug, or a cord that feels hot are all reasons to call.

Leave these alone

  • Don’t keep using an outlet, switch or cord that’s hot, discolored or smells.
  • Don’t touch a panel or breaker that’s hot, smoking or smells burnt. Get away from it.
  • Don’t reset a breaker that tripped with a burning smell.
  • Don’t open the outlet, switch or panel to look.
  • If the smell or smoke is at the meter or the wires outside, stay away and call 911, then PG&E (PG&E).

Common questions

Is a warm outlet normal?

Slightly warm can be okay, especially a dimmer switch. Hot is not. If you can’t comfortably keep your hand on the cover plate, stop using it and call an electrician.

What does a burning plastic smell from an outlet mean?

Usually that something is overheating, like a loose connection, an overloaded plug or a damaged device. Stop using it, turn off the breaker if it’s safe to reach, and call. If there’s smoke, call 911.

My outlet cover is brown or black around the slots. Is that bad?

Yes. Discoloration is a sign of heat. Stop using that outlet and have it checked.

There’s a burning smell but I can’t find where it’s coming from.

If there’s any smoke, or the smell is getting stronger, get out and call 911. Otherwise, turn off and unplug what you can, and call us. We’ll help you track it down.

Should I turn off the main breaker?

If the panel itself is fine and you can reach it without touching anything hot or wet, turning off the affected breaker, or the main, is a reasonable step. If the panel is the hot or smelly part, stay away from it and call 911.
